Coupler PVC, skt, rrj/flange, 200mm x 8" (Product Code: SLE/WDF/30) is a uPVC flanged coupling used to connect a 200 mm outside-diameter PVC pipe to 8" nominal-diameter flanged G.I. fittings, valves or equipment on large water mains. One end is a rubber ring socket that the PVC pipe pushes into; the other is a flange that bolts to the metal side. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the 200mm PVC Flanged Coupler Used For?

Large-bore mains usually meet valves, pump stations, meters and older metal pipework at a bolted flange. This coupling bridges the two systems: the 200 mm PVC pipe enters a rubber ring socket, so no solvent cement is used on that side, while the flange bolts to an 8" G.I. flange. Rubber ring joints also allow a little movement, which helps long mains cope with expansion and ground settlement.

Chamfer and clean the pipe spigot, apply a lubricant suitable for the rubber ring, and push the pipe home squarely without twisting the ring out of its groove. On the flange side, use a gasket between the faces and tighten the bolts evenly in a cross pattern. Confirm with us which gasket and bolt set you need, and keep service within 10 bar at 20°C.

What to Specify When Ordering

• PVC side: 200 mm outside-diameter pipe suitable for rubber ring jointing.
• Flange side: 8" nominal diameter; share your flange drilling standard so we can confirm it matches.
• Gasket, bolts and ring lubricant: say whether you need them sourced with the coupling.
• Quantity: one per flanged connection on the main.

Frequently Asked Questions

What does the Coupler PVC, skt, rrj/flange, 200mm x 8" connect?
The Coupler PVC, skt, rrj/flange, 200mm x 8" connects a 200 mm outside-diameter PVC pipe, pushed into its rubber ring socket, to an 8" nominal-diameter flanged G.I. fitting, valve or piece of equipment bolted to its flange.

Does the 200mm rubber ring flanged coupler need solvent cement?
No. The PVC side of the 200mm rubber ring flanged coupler seals with a rubber ring, so the chamfered pipe is lubricated and pushed in rather than cemented. Solvent cement should not be used on rubber ring joints.

What pressure is the 200mm x 8" PVC flanged coupler rated for?
The 200mm x 8" PVC flanged coupler is rated 10 bar at 20°C and suits water between 0 and 50°C. PVC carries less pressure as temperature increases, so the main's design pressure should reflect the actual water temperature.

Is the Coupler PVC, skt, rrj/flange, 200mm x 8" suitable for drinking water?
Confirm with us before using the Coupler PVC, skt, rrj/flange, 200mm x 8" on a drinking-water main. Utilities and project engineers should describe the application through the contact page and ask what ScienceLab can confirm for the supplied batch.

Elbow 90º Equal PVC, fxf, rrj, 200mm OD-P (Product Code: SLE/WDF/31) is a large-bore uPVC 90° elbow used to turn a 200 mm outside-diameter PVC water main through a right angle in buried or surface pipelines. Both ends are female rubber ring sockets, so pipes are lubricated and pushed in rather than cemented, which suits big-diameter mains laid in trenches. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the 200mm PVC Rubber Ring Elbow Used For?

Trunk mains of 200 mm follow roads, boundaries and site layouts, and every right-angle turn needs a bend of the same size. This elbow provides that turn with push-fit rubber ring sockets, which are quicker to make in a trench than solvent joints on large pipe and tolerate small movements caused by temperature change or settlement.

Because rubber ring joints are not designed to resist being pushed apart, the water pressure at a bend creates a thrust that the joints alone should not carry. Pressurised mains therefore normally have a concrete thrust block or other restraint at each bend, sized by the system designer. Chamfer and lubricate each spigot, push it fully home, and keep the main within 10 bar at 20°C.

What to Specify When Ordering

• Pipe size: 200 mm outside-diameter PVC suited to rubber ring joints.
• Angle: this item is a 90° bend; ask us if your route needs a different angle.
• Ring lubricant: say whether you need it sourced with the fittings.
• Quantity: one per right-angle turn on the route drawing.

Supplier

This 200 mm rubber ring elbow is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab. Its sourced pipeline range covers PVC, HDPE and G.I. fittings for water schemes, and buyers can handle them on the same enquiry as laboratory or hygiene products.

Frequently Asked Questions

What pipe does the Elbow 90º Equal PVC, fxf, rrj, 200mm OD-P fit?
The Elbow 90º Equal PVC, fxf, rrj, 200mm OD-P fits PVC pipe of 200 mm outside diameter on both ends. Each female end has a rubber ring seal, so the chamfered, lubricated pipe is pushed in rather than solvent-cemented.

Does the 200mm PVC rubber ring elbow need a thrust block?
On a pressurised main, the 200mm PVC rubber ring elbow normally needs a thrust block or other restraint, because rubber ring joints are not designed to hold the thrust that water pressure creates at a bend. The system designer should size it.

What pressure is the 200mm PVC rubber ring elbow rated for?
The 200mm PVC rubber ring elbow (Elbow 90º Equal PVC, fxf, rrj, 200mm OD-P) is rated 10 bar at 20°C and suits water from 0 to 50°C. Warmer water lowers PVC's safe pressure, so allow for the service temperature.

Is the Elbow 90º Equal PVC, fxf, rrj, 200mm OD-P suitable for drinking water?
Please check drinking-water suitability of the Elbow 90º Equal PVC, fxf, rrj, 200mm OD-P with us for your application first. For a utility main or tender, raise the question through the contact page when requesting a quotation, and we will state what we can confirm for the batch.

Respiration Apparatus (Product Code: SLE/BL/039) is a two-tube glass set-up used to compare inhaled and exhaled air in school biology lessons on respiration. It comprises two stoppered boiling tubes with one short and one long length of 5 mm glass tubing, joined by PVC tubing and a plastic T, and is listed for testing inhaled and exhaled air in small organisms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of biology lab equipment in India, at its own factory in Ambala.

Specifications

What Is the Respiration Apparatus Used For?

Both tubes are part-filled with a carbon dioxide indicator such as limewater; in each stopper the long glass tube reaches below the liquid and the short one stays above it. The PVC tubing links the plastic T to the short tube of one boiling tube and the long tube of the other, so that air drawn in bubbles through the first tube on its way in and air breathed out bubbles through the second. Because exhaled air carries more carbon dioxide, the indicator in the "out" tube changes first — limewater turns milky, for example — giving a clear side-by-side comparison in a single lesson.

Before anyone breathes through the T-piece, the teacher should check which tube is which, since an assembly error can draw liquid towards the mouth. Breathe gently, use a clean mouthpiece for each person and rinse the tubes after the lesson. A standard item on any school lab instruments list, the apparatus also supports follow-on discussion of how the same comparison applies to other organisms that respire.

What to Specify When Ordering

• The number of sets — each has two stoppered boiling tubes, short and long 5 mm glass tubing, PVC tubing and a plastic T.
• Whether spare boiling tubes or bored stoppers should be quoted with the sets.
• Whether you need lime water or another carbon dioxide indicator, as none is listed with the apparatus.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, is the OEM (original equipment manufacturer) of the Respiration Apparatus and makes it at its own licensed factory at Saha, Ambala, India. Registered as an MSME under Udyam number UDYAM-HR-01-0003714, the company moves its overseas consignments under Importer-Exporter Code AAECJ8618A issued by the DGFT.

Frequently Asked Questions

What parts make up the Respiration Apparatus?
The Respiration Apparatus comprises two boiling tubes, each with a stopper, and two lengths of 5 mm glass tubing, one short and one long, connected by PVC tubing and a plastic T. Together these let air be drawn in through one tube and breathed out through the other.

Is limewater or indicator supplied with the Respiration Apparatus?
No indicator is listed as part of the Respiration Apparatus. Lime Water is available separately in our range, and your syllabus may suggest another carbon dioxide indicator; mention it in your enquiry and we will add it to the quotation.

What diameter is the glass tubing of the Respiration Apparatus?
The glass tubing of the Respiration Apparatus is 5 mm. In use, the long length dips below the indicator liquid while the short length stays above it, so that air bubbles through the liquid in one direction only.

How should students breathe through the Respiration Apparatus?
Students should use the Respiration Apparatus only under teacher supervision: check the tube arrangement first, breathe gently and give each person a clean mouthpiece. Nobody should suck hard on the T-piece, because an assembly error can draw liquid towards the mouth.

Respirometer (Product Code: SLE/BL/040) is a compact manometer apparatus used to compare the rates at which small organisms absorb or give off gases during respiration in school and college biology laboratories. Students set up two stoppered boiling tubes — one for the organisms, one acting as a control thermo-barometer — joined by three-way taps to a graduated manometer. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, among its biology lab equipment in India.

Specifications

What Is the Respirometer Used For?

A typical practical places germinating seeds or small invertebrates such as woodlice on the wire basket of the experimental tube, above a layer of potassium hydroxide solution; the control tube is prepared the same way with inert material, such as glass beads, in place of living organisms. With the taps open, the syringe brings the manometer liquid to a starting level, then the taps are closed and timing begins. As the organisms take in oxygen and their carbon dioxide is absorbed, the gas volume in the experimental tube falls and the liquid moves along the graduated scale.

Readings taken at regular intervals give a rate that can be compared between species, temperatures or stages of germination. The thermo-barometer is what makes those comparisons fair: room temperature and air pressure act on both tubes equally, so only the organisms' gas exchange shows as a difference, and standing both tubes in one water bath helps further. Potassium hydroxide is corrosive, so wear eye protection, keep the organisms clear of the liquid and return live animals to their habitat — routine good practice for any biology lab setup in schools in India.

OEM Manufacturer

The Respirometer is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab. The company is the OEM (original equipment manufacturer) of this apparatus and makes it at its own licensed factory at Saha, Ambala, Haryana, India, rather than buying it in from a trader. Schools, colleges, dealers and importers are supplied factory-direct, and if you later need replacement wire baskets or extra units for more benches, ask us — the request is handled by the manufacturer itself. More about the company is on our company profile.

Frequently Asked Questions

Who manufactures the Respirometer?
The Respirometer (SLE/BL/040) is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and spare-part requests go straight to the manufacturer.

Is potassium hydroxide supplied with the Respirometer?
No, potassium hydroxide is not listed as part of the Respirometer, which comes complete with wire baskets for supporting the organisms. The carbon dioxide absorbent can be ordered separately as Potassium Hydroxide from our chemical range.

What is the second tube of the Respirometer for?
The second boiling tube of the Respirometer acts as a control thermo-barometer. Because temperature and air-pressure changes affect both tubes equally, the difference shown on the graduated manometer reflects only the gas exchange of the organisms in the experimental tube.

What does the syringe on the Respirometer do?
The syringe fitted to the organism tube of the Respirometer alters the level of liquid in the manometer during set-up, so each run starts from a known reading before the three-way taps are closed and timing begins.

What is the scale range of the Respirometer's manometer?
The Respirometer's manometer is graduated, but its scale range and divisions are not stated in our product information. Please ask through the contact page and we will confirm the scale details for the units you are quoted.

Tulgren Funnel (Product Code: SLE/BL/041) is a Tullgren-type extraction funnel used to drive small animals out of a soil or leaf-litter sample and into a collecting jar during ecology fieldwork and biology practicals. Schools and colleges add its 175mm funnel and 170mm sieve, 65mm deep, to their zoology lab equipment in India, with a 220V heating lamp held above the sample. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Tullgren Funnel Used For?

Clamp the funnel to a stand with the supplied horizontal rod and bosshead, put a collecting jar under the spout, and spread the soil or leaf-litter sample on the perforated plate over the chosen mesh. Coarse mesh lets larger animals drop through freely, while fine mesh stops loose soil from falling into the jar with them. Switch on the lamp above the sample: as the surface warms and dries, mites, springtails, beetle larvae and other soil organisms move downwards and fall through the funnel. A little alcohol in the jar preserves specimens for counting; damp tissue keeps them alive for study and release.

Keep to a bulb of 40 watt or less as specified, because stronger heat can kill animals before they have time to move out. Position the lamp so it cannot touch the sample or any alcohol, and switch it off before handling the set-up. Running several funnels side by side lets a class compare habitats such as lawn, hedge and compost in one session, which makes this a practical centrepiece for an ecology science kit in India.

What to Specify When Ordering

• The number of funnels — one per group if the class will compare several habitats at once
• Whether you also need stands to take the supplied horizontal rod and bosshead
• A suitable low wattage B22D bayonet bulb of 40 watt or less for each funnel, and whether you want us to quote for bulbs
• Your mains voltage, since the heating lamp is specified at 220V

OEM Manufacturer

This funnel comes from Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, which is the OEM (original equipment manufacturer) and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Because the maker is also the seller, schools, colleges, dealers and importers deal directly with the factory for quotations, repeat batches and questions about spare meshes or fittings — just ask us. Read about the company on our company profile.

Related Biology Lab Equipment

Items that complete a soil-fauna extraction set-up:

• Retort Stand — a stand for mounting the funnel with the supplied rod and bosshead
• Garden Auger Soil — for collecting soil samples to load onto the sieve
• Quadrat — for choosing comparable sampling areas in the field
• Plastic Container with a Magnifying Glass Lid — for viewing extracted animals up close
• Stereo Binocular Microscope — for identifying mites, springtails and other small finds

Our Biology Lab Equipment category lists further fieldwork and laboratory items.

Frequently Asked Questions

What are the dimensions of the Tulgren Funnel?
The Tulgren Funnel has a funnel diameter of 175mm and a sieve diameter of 170mm, with a sieve depth of 65mm. That leaves room for a typical soil or leaf-litter sample spread over the coarse or fine mesh on the perforated plate.

Which bulb does the Tulgren Funnel need?
The Tulgren Funnel needs a low wattage bulb with a B22D bayonet fitting of 22mm diameter, rated at 40 watt or less, in its 220V heating lamp. Keeping to that rating warms the sample gently, so animals move down rather than dying in place.

Are a bulb and collecting jar included with the Tulgren Funnel?
The Tulgren Funnel is supplied with a horizontal support rod, a bosshead and coarse and fine mesh. Our product information states that a bulb is required but does not confirm that a bulb or jar is included, so please check with us when ordering.

Why does the Tulgren Funnel come with two meshes?
The Tulgren Funnel includes coarse and fine mesh so the sieve can match the sample: coarse mesh lets larger animals pass freely from crumbly material, while fine mesh holds back more loose soil and keeps the collecting jar cleaner for counting.

Can the Tulgren Funnel be used where the mains supply is not 220V?
The heating lamp for the Tulgren Funnel is specified at 220V. If your laboratory runs on a different mains voltage, contact us before ordering so we can advise on a suitable arrangement for your country or region.

How does the Tulgren Funnel differ from the Funnel Tullgren listing?
Both use the same heat-driven extraction principle. The Tulgren Funnel listing gives dimensions, a support rod, bosshead and two meshes, while Funnel Tullgren describes the method in more detail; compare both and ask us which suits your class.

Who manufactures the Tulgren Funnel?
Jain Scientific Equipments Private Limited, trading as ScienceLab, manufactures the Tulgren Funnel as the OEM at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers in India and international markets buy it direct from the manufacturer.

Enzyme Biotechnology Kit (Product Code: SLE/BL/042) is a practical experiment kit used to show how industry uses enzymes, in senior secondary school and college biotechnology classes. Its four experiments cover enzymes in washing powders, pectinase in fruit juice production, rennet in cheese production and protease in meat tenderisers. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a biotechnology lab kit for schools and colleges.

Key Details

What Is the Enzyme Biotechnology Kit Used For?

Each experiment links a classroom test to a product students already know. With washing powders, they compare how biological detergent breaks down protein-based stains against a non-biological control. In the pectinase demonstration, fruit pulp treated with the enzyme releases more juice, and clearer juice, than untreated pulp. Rennet shows milk proteins clotting into curds — the first step in cheese making — and the meat tenderiser experiment shows a protease digesting a protein sample.

The set-ups make a good enzyme experiment kit for school coursework because variables such as temperature, enzyme concentration and time can each be changed and graphed. They also open a discussion of why industry now sources many enzymes from micro-organisms rather than from traditional sources such as animal tissue. Use a water bath to hold temperatures steady, measure volumes carefully for fair comparisons, and store the enzyme components as their labels direct when the kit arrives.

The set lets students work system by system through human tissue types: nervous tissue in the cerebellum, spinal cord and nerve; the layered walls of artery and vein; the digestive tract from oesophagus to colon; and glandular organs such as the liver, pancreas and thyroid. Comparing striated muscle with cardiac muscle is a classic practical exercise that the set supports directly.

Scalp and heavily pigmented skin sections show the epidermis, hair follicles and pigment, while the testis, ovary, uterus, cervix and mammary gland slides support reproduction lessons. Locate each tissue layer at low power, switch to higher magnification to identify cell types, and record observations as labelled drawings.
