Bell Jar (Plant Physiology) (Product Code: SCL1455/020) is a bell-shaped glass cover, 20 x 10 cm, used to enclose a small plant, specimen or piece of apparatus so that the air around it can be controlled and observed in plant physiology practicals. Made of thin, transparent, heat-resistant glass with care for optical clarity, it can also contain a vacuum when set on a suitable plate. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Plant Physiology Bell Jar Used For?

To show transpiration, a well-watered potted plant is placed under the jar with the pot and soil wrapped in polythene; within a few hours droplets form on the inside of the glass, and cobalt chloride paper placed inside turns from blue to pink. For photosynthesis, a destarched plant kept under the jar beside a dish of alkali that absorbs carbon dioxide is compared with a control plant, and the leaves are then tested with iodine. Germinating seeds under the jar with a dish of lime water show that respiration releases carbon dioxide.

Stand the jar on a smooth glass plate and seal the rim with a thin film of petroleum jelly whenever the enclosed air must be isolated. The clear glass lets students watch changes without lifting the cover, which is why the bell jar remains standard botany lab equipment in India for these three classic experiments.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of this bell jar and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Because it is made by the company rather than bought in from a trader, schools, colleges, dealers and importers receive it factory-direct, and repeat orders or replacements after breakage are handled by the manufacturer itself — just ask. More about the company is on its profile page.

Cavity Slides (Single Cavity) (Product Code: SCL1557/021) are rectangular microscope slides in clear borosilicate glass with one concave well, used to hold a drop of culture or a small living organism for observation without crushing it under a coverslip. Biology and microbiology students use them for hanging-drop preparations and live-specimen study, and the heat- and chemical-resistant glass stands up to repeated cleaning. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Are Cavity Slides Used For?

In the hanging-drop method, a drop of broth culture or pond water is placed on a coverslip, the rim of the cavity is ringed with a little petroleum jelly, and the slide is lowered over the coverslip and turned the right way up. The drop then hangs inside the well, where students can watch bacterial motility or the swimming of Paramecium, Euglena and other protozoa without the sample drying out. The well is also handy for germinating pollen grains in a drop of sugar solution.

Find the edge of the drop with the low-power objective before moving to higher magnification. Because the borosilicate glass is chemical resistant, the slides can be cleaned with alcohol and used again, and they sit comfortably alongside stains and coverslips as part of the microbiology lab equipment in India’s school and college labs.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited of Ambala, Haryana, which supplies these cavity slides to schools, colleges, laboratories and dealers in India and international markets, often in the same order as coverslips, stains and microscopes. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). The company profile has further details.

Plain Slides (Product Code: SCL1462/022) are flat, clear glass microscope slides measuring 75 x 25 mm and 1.2 mm thick, used to carry temporary mounts, smears and stained sections for viewing under a compound microscope. Their ground edges make them safer for students to handle and clean, and the chemical-resistant glass takes routine stains. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools building a microscope slides set for practicals.

Specifications

What Are Plain Microscope Slides Used For?

Plain slides carry onion-peel and cheek-cell preparations, leaf epidermal peels that show stomata, thin hand-cut sections of stem and root, and blood or bacterial smears. The chemical-resistant glass is unaffected by stains such as safranin, methylene blue and iodine, or by the alcohol used for cleaning and fixing, which makes them the basic consumable in any temporary slides biology kit.

Wipe each slide with alcohol before making a smear so the film spreads evenly, hold slides by their ground edges, and label one end with a marker so that preparations are not mixed up. The 75 x 25 mm format sits securely under the stage clips of common school and college microscopes.

Coverslips (Product Code: SCL1365/023) are thin 18 x 18 mm glass squares placed over a specimen on a microscope slide to keep solid material pressed flat and to spread liquid samples into a flat layer of even thickness. Students and technicians use them on every wet mount, stained preparation and hanging drop, so they are among the first items in a microscopy starter kit for schools. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Are Coverslips Used For?

Once a drop of water, glycerine or stain has been placed on the specimen, the coverslip is touched to the slide at an angle and lowered slowly with a needle, so that air is pushed out rather than trapped as bubbles. Excess liquid at the edges is drawn off with a strip of blotting paper. The even layer this creates lets the objective focus across the whole field, and the glass also keeps stains and water off the lens.

In the hanging-drop method the coverslip carries the drop over the well of a cavity slide. Because coverslips are very thin, handle them by the edges or with forceps, keep them in their container until needed, and clean them with alcohol before use for the clearest view.

Supplier

Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, supplies these coverslips from Ambala, Haryana, as part of the slides, stains and microscopy consumables it provides to schools, colleges, laboratories and dealers in India and international markets. See the company profile for more.

Related Biology Lab Equipment

Items used with coverslips when preparing and staining mounts:

• Plain Slides — the base slide for most temporary mounts.
• Cavity Slides (Single Cavity) — for hanging-drop preparations under a coverslip.
• Glycerine — a mounting medium that slows drying under the coverslip.
• Acetocarmine (Nucleic Acid) — stains chromosomes in root-tip squash preparations.
• Brush — transfers thin sections onto the slide before covering.

See the Biology Lab category for more slides, stains and specimens.

Frequently Asked Questions

What size are the Coverslips?
The Coverslips are 18 x 18 mm squares of glass. That size covers a typical onion-peel, cheek-cell or root-tip preparation on a standard microscope slide while leaving room at the ends of the slide for a label.

What thickness are the Coverslips?
The thickness of the Coverslips is not specified in their product details. If your microscope objectives call for a particular coverslip thickness, confirm it with ScienceLab through the contact page before placing the order.

How do you avoid air bubbles under the Coverslips?
Touch one edge of the Coverslips to the liquid first and lower each one slowly with a needle or forceps. The liquid then spreads outward across the specimen and pushes the air out ahead of it, leaving a clear, bubble-free mount.

Can the Coverslips be reused?
The Coverslips can be cleaned carefully with alcohol and reused, but most laboratories treat them as consumables because the thin glass breaks easily. Put broken pieces in a glass waste container rather than an ordinary bin.

How many Coverslips come in a pack?
The pack quantity of the Coverslips is not listed on this page. Please ask when requesting a quotation, and mention how many slides your classes prepare so that ScienceLab can suggest a sensible order quantity.

Who supplies the Coverslips?

Measuring Cylinder (Product Code: SCL1699/030) is a 25 ml graduated cylinder in clear borosilicate glass, used to measure small volumes of reagents, stains and water more accurately than a beaker allows in biology and chemistry practicals. Its heat- and chemical-resistant glass and small capacity make it a routine choice when schools order a measuring cylinder for school labs in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 25 ml Measuring Cylinder Used For?

The 25 ml size suits small measured volumes: reagents for food tests, water for seed-soaking experiments, sugar or salt solutions for osmosis work and dilutions of stains. Stand the cylinder on a level bench, bring your eye level with the liquid and read the bottom of the meniscus against the graduation. For volumes of only a few millilitres a pipette gives better precision.

Although the glass is heat resistant, a measuring cylinder should not be heated over a flame, because heating can affect the accuracy of its volume markings; warm washing water is fine. Chemical resistance means that acids, alkalis and stains will not etch the glass, so the scale stays readable through years of shared use between biology and chemistry rooms.

OEM Manufacturer

This measuring cylinder is produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM (original equipment manufacturer) and makes its glassware at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers are supplied factory-direct rather than through a trader, and orders for matching glassware or replacements go straight to the manufacturer. The company profile gives more background.

Items used with the measuring cylinder when preparing solutions:

• Beaker — receives the measured liquid for mixing or warming.
• Pipette — for volumes too small to read accurately on the cylinder.
• Distilled Water — for making up and diluting solutions.
• Wash Bottle LDPE with Narrow Mouth — tops up to the mark drop by drop.
• Measuring Cylinder, Polypropylene — a plastic alternative where breakage is a concern.

Find more glassware in the Biology Lab category.

Frequently Asked Questions

What capacity is the Measuring Cylinder?
The Measuring Cylinder holds up to 25 ml and is graduated along its length, which makes it suited to the small reagent and stain volumes used in school practicals rather than to bulk solution preparation.

How do you read the Measuring Cylinder accurately?
Place the Measuring Cylinder on a level surface, bring your eye level with the liquid and read the bottom of the curved meniscus against the nearest graduation. Reading from above or below the line gives a parallax error.

Can the Measuring Cylinder be heated?
Avoid heating the Measuring Cylinder directly. Its borosilicate glass is heat resistant, but measuring vessels are not meant for heating because it can affect their markings; warm liquids in a beaker or flask and measure them once cooled.

Why choose the glass Measuring Cylinder over a plastic one?
The glass Measuring Cylinder is chemical resistant, easy to see through and does not stain, which suits reagent and dye work. A polypropylene cylinder is the better choice where breakage is the bigger concern, such as with younger classes.

Who manufactures the Measuring Cylinder?
The Measuring Cylinder (SCL1699/030) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and is sold factory-direct to institutions, dealers and importers.

Ganog's Potometer (Product Code: SCL2409/033) is a borosilicate glass apparatus of the Ganong type used to measure how quickly a leafy plant shoot takes up water, giving students a practical estimate of the rate of transpiration in plant physiology classes. It is fabricated from imported glass tubing for a durable structure, and it anchors any transpiration experiment kit in India’s schools and colleges. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Ganong’s Potometer Used For?

A freshly cut leafy shoot is fitted into the apparatus so that the joint is airtight, and the apparatus is filled with water. A small air bubble is introduced into the capillary, and its movement over a measured distance in a set time shows how fast the shoot is drawing up water. Because almost all of the water taken up is lost from the leaves, the reading serves as a measure of the transpiration rate.

Cut the shoot under water to stop air entering the xylem, seal the joints with petroleum jelly and let the shoot settle before timing. Students can then compare rates in still and moving air, in light and shade, or at different temperatures, turning a textbook idea into measured data with a single piece of plant biology lab equipment.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this potometer: the apparatus is fabricated from imported glass tubing at the company’s own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers therefore buy it straight from the people who make it, and questions about replacement glass parts or repeat sets are answered by the manufacturer directly. See the company profile.

• Stomata — a slide showing the pores through which water vapour escapes.
• Kit for Demonstration of Transpiration in Plants — a complementary set for the same topic.

Further apparatus is in the Biology Lab category.

Frequently Asked Questions

Does the Ganog's Potometer measure transpiration directly?
The Ganog's Potometer measures the rate at which a leafy shoot takes up water. Since nearly all of that water is lost through the leaves, the uptake rate is used as an estimate of the transpiration rate rather than a direct measurement of it.

What is the Ganog's Potometer made of?
The Ganog's Potometer is made of borosilicate glass and is fabricated from imported glass tubing that gives it a durable structure. Glass also lets students see the air bubble clearly as it moves along the capillary during a reading.

Is a stopper or plant shoot supplied with the Ganog's Potometer?
Plant material is not supplied with the Ganog's Potometer, and accessories are not listed in its product details. Please confirm the set contents with ScienceLab through the contact page before ordering.

How can reliable readings be obtained with the Ganog's Potometer?
Cut the stem under water, make every joint of the Ganog's Potometer airtight and wait a few minutes after setting up before timing the bubble. Repeat each reading at least three times under the same conditions and take the average.

Who manufactures the Ganog's Potometer?
The Ganog's Potometer (SCL2409/033) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, which fabricates it from imported glass tubing at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct.

How should the Ganog's Potometer be cleaned and stored?
Flush the Ganog's Potometer with clean water after use, let it drain and dry fully, and store it in padded packing or a fixed rack so that the glass tubing is not stressed or knocked between practicals.

Can colleges order several Ganog's Potometers?
Yes. Several Ganog's Potometers can be quoted together for a botany or plant physiology laboratory; mention the quantity and delivery location. ScienceLab supplies institutions and dealers in India and international markets directly as the manufacturer.

Osmotic Pressure Apparatus (Product Code: SCL222/034) is a glass demonstration set used to show osmosis and osmotic pressure at elementary levels in school biology classes. A semipermeable membrane seals the open mouth of a thistle funnel fitted with an indicator tube, the funnel stands in a reservoir, and a dropping pipette is supplied with the set. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Osmotic Pressure Apparatus Used For?

It is used to make the movement of water across a membrane visible to a whole class. The funnel is filled with a concentrated sugar solution, the membrane is secured over its mouth, and the funnel is placed mouth-down in a reservoir of water with the indicator tube held upright. Water moves through the membrane into the more concentrated solution and pushes the column up the tube; marking the level at intervals turns the demonstration into a simple set of readings. The dropping pipette is used to adjust the starting level precisely.

Tie the membrane tightly and check for leaks before starting, clamp the tube vertically and add a little food colour to the sugar solution so the column is easy to see from the back of the room. As an osmosis experiment kit for school classes, the set suits the secondary years in which osmosis is first taught.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM of this apparatus and makes it at its own licensed factory at Saha, Ambala, Haryana, India.
