Acetocarmine (Nucleic Acid) (Product Code: SCL451/0134) is a chromosome stain used to colour nuclei and chromosomes deep red for observing cell division in biology practicals. Students rely on it for onion root tip squashes and flower-bud meiosis preparations because the cytoplasm stays pale, and it is packed as 125 ml of analytical reagent grade stain with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a core part of any staining kit for a biology lab.

Specifications

What Is Acetocarmine Stain Used For?

The onion root tip squash is the classic practical. Freshly grown root tips are fixed, softened in warm dilute hydrochloric acid so the cells separate, and then warmed gently in a few drops of acetocarmine in a watch glass over a spirit lamp without boiling. The tip is moved to a slide, covered with a coverslip and pressed firmly to spread the cells into a single layer. Under the microscope the chromosomes stand out clearly, and students can identify prophase, metaphase, anaphase and telophase in the same field.

Young anthers from flower buds are squashed the same way to show stages of meiosis, and college classes also use the stain for salivary gland chromosomes. Comparing a student's temporary slide with a reference slide of the same tissue is a good way to check technique. The stain contains acid, so use it in a ventilated area, keep it off skin and clothing, and wipe the underside of the slide before it goes on the microscope stage.

Frequently Asked Questions

How much stain is in a pack of Acetocarmine (Nucleic Acid)?
Each pack of Acetocarmine (Nucleic Acid) contains 125 ml of analytical reagent grade stain, supplied with an MSDS. A few drops are enough for one root tip preparation, so a single pack lasts a class through many practical sessions.

Is Acetocarmine (Nucleic Acid) ready to use?
The listing for Acetocarmine (Nucleic Acid) gives the pack size and grade but not the working strength. If your practical manual specifies a particular strength or preparation, share it through the contact page and we will confirm whether this stain suits it.

Why are the chromosomes pale after staining?
Pale chromosomes with Acetocarmine (Nucleic Acid) usually mean the root tip was not softened or warmed enough, or the cells were not squashed flat. Warm the tip in the stain without boiling, then press the coverslip evenly to spread the cells into one layer.

What is the shelf life of Acetocarmine (Nucleic Acid)?
Shelf life depends on the chemical, its grade and storage conditions, so we do not state a blanket period for Acetocarmine (Nucleic Acid). Ask us for the expiry date of the batch you are quoted, keep the bottle tightly closed and away from heat, and filter the stain if a deposit forms.

Who supplies Acetocarmine (Nucleic Acid)?
Acetocarmine (Nucleic Acid) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. Alongside the stain, the company can quote watch glasses, coverslips and reference slides, so colleges can order a complete mitosis practical in one enquiry.

Eosin (Cytoplasm) (Product Code: SCL452/0135) is an acidic dye used to stain cytoplasm, muscle fibres, connective tissue and red blood cells pink in histology and cell biology practicals. Medical, paramedical and science colleges use it mainly as the counterstain to haematoxylin, and it comes as a 500 ml pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a routine item of zoology lab equipment.

Specifications

What Is Eosin Stain Used For?

Eosin is best known as the second half of haematoxylin and eosin (H and E) staining, the combination used to study tissue sections in histology courses. After sections are stained with haematoxylin and blued, the slides pass briefly through eosin, are rinsed, and are taken through graded alcohols before clearing and mounting. The result shows purple-blue nuclei against pink cytoplasm and fibres, the view most textbooks use for epithelium, muscle, liver or kidney sections.

Students preparing permanent slides soon learn that timing matters: a longer dip or less time in the alcohols gives a deeper pink, while extra rinsing lightens it. Eosin can also be used on its own for a quick temporary mount of cheek cells or to highlight cytoplasm in simple animal tissue preparations. Use a staining jar so several slides are treated evenly, keep the jar covered between runs, and wipe drips promptly, because the dye marks benches and fingers.

Supplier

Jain Scientific Equipments Private Limited, operating as ScienceLab, is located in Ambala, Haryana. It supplies stains, reagents, glassware and teaching apparatus to schools, colleges, medical and paramedical institutes and research laboratories in India and international markets.

More stains and slide supplies are in the Biology Lab category.

Frequently Asked Questions

How much eosin comes in one pack of Eosin (Cytoplasm)?
One pack of Eosin (Cytoplasm) holds 500 ml of analytical reagent grade stain and is supplied with an MSDS. Because slides are only dipped briefly, the same stock can serve a histology class across many staining runs when it is kept covered between uses.

Do I need haematoxylin as well as Eosin (Cytoplasm)?
For standard H and E staining, yes: haematoxylin stains the nuclei blue-purple and Eosin (Cytoplasm) stains the cytoplasm and fibres pink. For a quick cytoplasm-only temporary mount, such as cheek cells, the eosin can be used on its own.

My sections are too pink. What should I change?
If sections stained with Eosin (Cytoplasm) look too pink, shorten the time in the stain or allow a little longer in the lower-strength alcohol, which removes excess dye. Test the timing on a single slide before staining the whole batch.

What is the shelf life of Eosin (Cytoplasm)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Eosin (Cytoplasm). Ask us for the expiry date of the batch you are quoted, store the bottle closed and away from light and heat, and filter the working stain if particles appear.

Who supplies Eosin (Cytoplasm)?
Eosin (Cytoplasm) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company quotes the stain together with haematoxylin, staining jars and slides, which lets histology departments order a complete H and E set in one request.

Can a medical college order larger quantities?

Fast Green (Proteins) (Product Code: SCL453/0136) is a green acid dye used to counterstain protein-rich and cellulose-walled plant tissue in section-staining practicals. Botany classes pair it with safranine so that thin-walled tissue shows green against red lignified walls, and it is packed as 100 ml of analytical reagent grade stain with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside the rest of its botany lab equipment.

Specifications

What Is Fast Green Stain Used For?

The double-staining practical in plant anatomy is where most students meet fast green. A thin transverse section of a dicot or monocot stem is cut with a razor, stained in safranine and rinsed, then dipped very briefly in fast green before a second rinse and mounting in glycerine. Lignified tissues such as xylem and sclerenchyma keep the red of safranine, while parenchyma, phloem and other thin-walled cellulose tissues take up the green, so the vascular bundles stand out sharply for drawing and labelling.

Fast green works quickly and can easily overpower the red, so a short dip is enough and it helps to test the timing on a spare section first. In higher classes the dye's affinity for proteins is also used in cell and protein staining exercises, which is why it is listed here for proteins. Pour only what is needed into a watch glass, return nothing to the stock bottle, and rinse the section well so excess dye does not cloud the mount.

Frequently Asked Questions

What size is a pack of Fast Green (Proteins)?
Each pack of Fast Green (Proteins) contains 100 ml of analytical reagent grade stain and is supplied with an MSDS. Because only brief dips are needed in section staining, the small pack goes a long way in a plant anatomy practical.

Can Fast Green (Proteins) be used without safranine?
Yes, Fast Green (Proteins) can stain on its own, but the classic contrast between lignified and non-lignified plant tissue needs both dyes. Most plant anatomy practicals therefore use safranine first and fast green as the counterstain.

Why do my sections look completely green?
Sections turn completely green when they stay too long in Fast Green (Proteins), which can displace the red safranine. Reduce the dip to a brief immersion, rinse promptly, and test the timing on a spare section before staining the class set.

What is the shelf life of Fast Green (Proteins)?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is stated for Fast Green (Proteins). Ask us for the expiry date of the batch you are quoted, and keep the bottle closed, away from strong light and heat.

Who supplies Fast Green (Proteins)?
Fast Green (Proteins) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company can quote it with safranine, glycerine, watch glasses and coverslips, so a complete double-staining practical can be ordered in one enquiry.

Haematoxylin (Histology) (Product Code: SCL454/0137) is a nuclear stain used to colour chromatin blue to purple in tissue sections, smears and cell preparations in histology laboratories. Medical, paramedical and life-science colleges use it as the first stain of the H and E method, and it comes as a 500 ml pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to colleges that prepare their own permanent slides for biology teaching.

Specifications

What Is Haematoxylin Stain Used For?

In a standard histology run, deparaffinised and rehydrated sections are placed in haematoxylin until the nuclei take up enough dye. The slides are then rinsed and blued in gently alkaline water, which turns the initial reddish tint to a crisp blue-purple. Where the stain is used regressively, a brief dip in acid alcohol removes excess colour from the cytoplasm before bluing, and counterstaining with eosin, dehydrating, clearing and mounting then complete the familiar H and E slide.

Colleges that cannot buy a prepared slide for every tissue in the syllabus often teach students to make their own, and a dependable haematoxylin is the foundation of that work. Filter the stain before use to avoid surface deposits on sections, keep the staining jar covered to reduce evaporation, and time each batch the same way so results match from one practical group to the next. Wear gloves, since the dye marks skin and benches.

Frequently Asked Questions

Is Haematoxylin (Histology) the product previously listed as Haemotoxicilin?
Yes. Haematoxylin (Histology) was previously listed under the misspelling Haemotoxicilin; the product code SCL454/0137 and the item are unchanged. It is haematoxylin, the nuclear stain used in histology, supplied as a 500 ml pack of analytical reagent grade with an MSDS.

Which haematoxylin formulation is this?
The listing for Haematoxylin (Histology) does not name a specific formulation, such as Harris or Mayer's haematoxylin. If your protocol requires one, ask us through the contact page before ordering so we can confirm whether this stain suits your method.

Why are the nuclei reddish instead of blue?
Nuclei stained with Haematoxylin (Histology) look reddish when the sections have not been blued long enough. Rinse them in gently alkaline water until the colour turns a crisp blue-purple, then continue with eosin, dehydration, clearing and mounting.

What is the shelf life of Haematoxylin (Histology)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is given for Haematoxylin (Histology). Ask us for the expiry date of the batch you are quoted, keep the bottle tightly closed away from sunlight and heat, and filter before use if a film forms.

Methylene Blue (Cellulose) (Product Code: SCL455/0138) is a blue biological stain used to add contrast to plant cell walls, nuclei and cell outlines for observation under a compound microscope. It is listed for cellulose, meaning plant cell wall work, although students also meet it in cheek-cell and simple bacterial smears, and it comes as 500 ml of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for school biology lab equipment lists.

Specifications

What Is Methylene Blue Stain Used For?

In a typical practical, a thin plant peel or section is laid on a clean glass slide, a drop of methylene blue is added and left briefly, the excess is drained or blotted away, and a coverslip is lowered at an angle so that no air bubbles are trapped. The blue dye binds to acidic components of the cell, so walls and nuclei stand out against a pale background. Outside plant work, the same dye is familiar from cheek-cell smears in introductory cell biology and from simple staining of bacterial smears in microbiology.

A 500 ml stock is far more than one class uses in a session, so most labs decant a working quantity into a small dropper bottle and keep the main container tightly closed and out of direct sunlight. Methylene blue marks skin, clothing and bench surfaces easily, so gloves, a lab coat and a tray under the slides are sensible precautions. The MSDS supplied with the reagent covers storage, handling and disposal for secondary and senior-secondary practicals on cell structure.

Safranine (Plant Tissue) (Product Code: SCL457/0139) is a red stain used to colour lignified cell walls and nuclei in plant sections before microscopic study in botany practicals. Colleges and schools use it to make xylem vessels and sclerenchyma fibres stand out in stem, root and leaf sections, and it is packed as 125 ml of analytical reagent grade stain with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its plant biology lab equipment range.

Specifications

What Is Safranine Stain Used For?

The classic exercise is staining free-hand transverse sections of stems and roots. Students cut thin sections, float them in a watch glass of water, move the best ones into a few drops of safranine until they take up colour, rinse off the surplus and mount them in glycerine under a coverslip. Lignified xylem and sclerenchyma show up red, which lets the class compare the vascular bundle pattern of dicot and monocot stems side by side. Safranine is also paired with a green counterstain such as fast green for double-stained preparations, and it is the usual counterstain in Gram's method in microbiology.

Each section needs only drops, so the 125 ml size suits a single lab section. Close the cap firmly after use so the stain does not concentrate through evaporation, wipe drips from the bottle neck, and follow the supplied MSDS for storage and disposal. Institutions stocking botany lab equipment usually order safranine together with slides, coverslips and plant section material so a full anatomy practical can run from one delivery.

See the full Biology Lab category for other stains, reagents and slides.

Frequently Asked Questions

What volume of Safranine (Plant Tissue) is supplied?
One container of Safranine (Plant Tissue) holds 125 ml of analytical reagent grade stain, supplied with an MSDS. Each section needs only a few drops, so this size suits a single lab section running regular plant anatomy practicals.

Which plant structures does Safranine (Plant Tissue) highlight?
Safranine (Plant Tissue) colours lignified walls, such as xylem vessels and sclerenchyma, and nuclei a strong red, while thin unlignified walls stain more lightly. This contrast is what makes vascular tissue easy to trace in stem and root sections.

Can Safranine (Plant Tissue) be used for double staining?
Yes. Safranine (Plant Tissue) is commonly combined with fast green, which colours the cellulose walls green while lignified tissue stays red. Staining times depend on your own protocol, and Fast Green (Proteins) is listed separately in the same category.

Can the same safranine be used in Gram staining?
Safranine is the usual counterstain in Gram's method, so many labs use one reagent for both purposes. The listing for Safranine (Plant Tissue) does not state a concentration, so please contact us if your microbiology protocol specifies one.

What is the shelf life of Safranine (Plant Tissue)?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is given for Safranine (Plant Tissue). Ask us for the expiry date of the batch you are quoted, and keep the container tightly capped, away from heat and direct light.

Sudan III (Animal Tissue) (Product Code: SCL458/0140) is a fat-soluble dye used to show lipids by staining fat droplets orange-red in animal tissue preparations and food tests. Biology and physiology classes rely on it because it dissolves far more readily in fats and oils than in water, and it is packed as 125 ml of analytical reagent grade stain with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a biology lab equipment supplier serving schools and colleges.

Specifications

What Is Sudan III Stain Used For?

For the food test, a little oil, butter or crushed food is shaken with water in a test tube and a few drops of Sudan III are added. After standing, any lipid collects as a red-stained oily layer at the surface, while a lipid-free sample leaves the colour evenly spread. In histology and physiology classes the stain is applied to fresh or frozen preparations of animal tissue, where it picks out fat droplets inside cells; routine alcohol-processed permanent sections generally lose their fat, so fresh material gives the clearest result.

Wear gloves, keep the container firmly closed and store it away from heat and open flames; the MSDS supplied with the reagent sets out storage, handling and disposal. Schools stocking school biology lab equipment in India often order Sudan III together with the sugar and protein test reagents, so the full food-test practical can run from one consignment.

Supplier

ScienceLab is the brand name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, which supplies stains, reagents and apparatus to teaching and research laboratories in India and international markets. For vendor registration and export paperwork, the supplying company holds Importer-Exporter Code AAECJ8618A (DGFT) and GSTIN 06AAECJ8618A1ZT. More background is on our company profile.

These items complete the food-test and lipid-staining practicals that Sudan III is used in:

• Benedict's Reagent (Test Of Glucose) — the reducing-sugar test that runs alongside the lipid test.
• Biuret Reagent (Protein Test) — the protein test that completes the food-test set.
• Test Tubes (With Rim) — for mixing food samples, water and stain.
• Ethanol — for the emulsion test, a common cross-check for lipids.
• Plain Slides — for mounting fresh tissue stained to show fat droplets.

More reagents and teaching slides are listed in our Biology Lab category.

Frequently Asked Questions

What does Sudan III (Animal Tissue) stain?
Sudan III (Animal Tissue) colours lipids such as fats and oils orange-red. Proteins and carbohydrates are not stained, which is why it is used as a specific test for fat in food samples and for fat droplets in fresh animal tissue.

How much Sudan III (Animal Tissue) is supplied?
Each container of Sudan III (Animal Tissue) holds 125 ml of analytical reagent grade stain and is supplied with an MSDS. A few drops are enough for each food test, so one container serves many student groups through the year.

Can Sudan III (Animal Tissue) be used on permanent animal tissue slides?
Usually not. Routine processing for permanent slides uses alcohol and clearing agents that dissolve fat, so Sudan III (Animal Tissue) works best on fresh or frozen tissue preparations where the lipid droplets are still present.

What is the shelf life of Sudan III (Animal Tissue)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is stated for Sudan III (Animal Tissue). Ask us for the expiry date of the batch you are quoted, and store it closed, cool and away from light and open flames.

Who supplies Sudan III (Animal Tissue)?

Sulphur Powder (Product Code: SCL459/0141) is analytical reagent grade sulphur in powder form, used for combustion, allotrope and compound-formation experiments in school and college science labs. This 500 g pack, supplied with an MSDS, suits institutions that run the same sulphur practical across many class groups. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Sulphur Powder Used For?

Burning a small amount of sulphur on a deflagrating spoon, inside a gas jar in a fume cupboard, produces sulphur dioxide; moist blue litmus paper held in the gas turns red, showing that non-metal oxides are acidic. Gently melting sulphur and pouring it into cold water forms rubbery plastic sulphur, a clear demonstration of allotropy.

With a 500 g pack, a department can portion sulphur into labelled containers for each bench or class set. Sulphur dust is flammable, so keep it away from open flames except during controlled experiments, carry out every burning test in a fume cupboard, and store the bulk pack closed in a cool, dry chemical cabinet away from oxidising agents.

What to Specify When Ordering

• Product code SCL459/0141 for the 500 g pack, or SCI-556/165 if 100 g packs suit your labs better.
• Number of packs and how many labs will share them.
• Delivery address, and whether the shipment is domestic or export.

Supplier

Sulphur Powder is sourced by Jain Scientific Equipments Private Limited, which trades as ScienceLab, and supplied with its MSDS to schools, colleges and laboratories in India and international markets.
