Borosilicate Nessler Cylinder Manufacturer,Supplier and Exporter in India

Product Code : SCL-B-12567

The Borosilicate Nessler Cylinder is a laboratory colour-comparison cylinder used for visually comparing the colour, clarity, or turbidity of liquid samples under controlled test conditions. It is suitable for school chemistry labs, college practicals, analytical laboratories, water-testing demonstrations, distributors, and institutional procurement buyers.

Product Description

Borosilicate Nessler Cylinder from School Equipments India is intended for supervised colour-comparison and analytical chemistry work. The cylinder supports practical demonstrations where students compare a sample solution with a reference solution or standard series by visual observation.

A Nessler cylinder is typically a flat-bottom laboratory cylinder with capacity marks used for consistent liquid-depth comparison. The product name specifies borosilicate construction, but exact borosilicate grade, capacity, graduation pattern, tolerance, stopper type, optical bottom finish, dimensions, and certificate availability should be confirmed before publication, quotation, or tender submission.

Key Features

• Colour-comparison use: designed for visual comparison of liquid colour, clarity, and turbidity.
• Borosilicate glass product name: suitable for laboratory glassware positioning; exact grade must be confirmed.
• Flat-bottom cylinder format: helps keep liquid depth consistent during side-by-side comparison.
• Reference-mark operation: supports filling to defined volume marks for repeatable visual observations.
• Chemistry teaching value: useful for colorimetry principles, solution comparison, and analytical observation skills.
• Manual laboratory method: requires no electrical supply or digital display.
• Procurement-safe specification: final capacity, tolerance, class, stopper, and compliance documents should be verified before order.

How to Use the Borosilicate Nessler Cylinder

1. Inspect the cylinder for cracks, chips, stains, scratches, or damaged graduation marks.
2. Clean and rinse the cylinder with the same liquid or solvent specified by the laboratory method.
3. Place the cylinder upright on a stable, level surface with good lighting.
4. Fill the sample cylinder to the required reference mark.
5. Fill the comparison cylinder or standard series to the same volume level.
6. Compare colour, clarity, or turbidity visually under consistent lighting and viewing conditions.
7. Record the comparison result according to the laboratory worksheet or analytical method.
8. Clean the cylinder immediately after use, especially when coloured or staining reagents are used.

Safety note: Use the cylinder only under trained supervision. Wear suitable PPE and handle reagents, including Nessler-type or mercury-containing reagents, strictly according to the SDS and laboratory SOP.

Care & Maintenance

• Clean after every use because stains and film can distort visual colour comparison.
• Avoid abrasive brushes or powders that may scratch the viewing surface.
• Store upright or padded in a glassware cabinet to prevent rim and base damage.
• Do not heat, autoclave, or use aggressive chemicals unless the final glass grade and product limits confirm suitability.

Frequently Asked Questions

What is a Borosilicate Nessler Cylinder used for?

A Borosilicate Nessler Cylinder is used for visual comparison of colour, clarity, or turbidity in suitable liquid samples. It is commonly used in chemistry and analytical observation practicals.

What capacity is available?

The capacity is not confirmed. Add 50 mL, 100 mL, matched pair, or set capacity only after checking the final School Equipments India quotation or datasheet.

Is it the same as a measuring cylinder?

No. A Nessler cylinder is mainly used for colour comparison at defined liquid depths. A measuring cylinder is primarily used for volume measurement.

Is the cylinder made from borosilicate glass?

The product name specifies borosilicate, but the exact grade should be confirmed from the final datasheet, product label, or certificate before publishing detailed material claims.

Does it meet IS 4161?

IS 4161:2023 is a relevant specification for Nessler cylinders. Compliance should be claimed only if School Equipments India supplies supporting documentation.

Can students use it in school chemistry labs?

Yes. It is suitable for supervised school and college chemistry laboratories when teachers control reagent handling, viewing conditions, cleaning, labelling, and glassware safety.
