Nessler Cylinder

Product Code : SCL-LG-11986

Nessler Cylinder (SKU SCL-LG-11986), also called a colour comparison cylinder or Nessler tube, is a glass cylinder for judging the colour, clarity or intensity of a test solution against a reference by eye. Pharmacy, chemistry and water-analysis practicals use it for limit tests and visual comparisons. The item reaches schools, colleges, testing laboratories, tender contractors and distributors through Science Lab Supplies, which supplies it from Ambala, India.

Specifications

The cylinder is a clear laboratory-glass vessel in which a sample and a reference solution, made up to the same specified volume in matched cylinders, are viewed side by side under the same lighting. It needs no electronic measuring system; comparison is made visually, as the chosen method sets out.

Applications and Experiments for the Nessler Cylinder

Nessler cylinders serve any test in which the depth of colour or turbidity of a sample is judged against a standard. Pharmacopoeial limit tests, colorimetric checks in water analysis and introductory lessons on semi-quantitative analysis all rely on pairs of these tubes viewed under identical conditions.

• B.Pharm pharmaceutical analysis: limit tests for chloride, sulphate and iron.
• Environmental and water analysis courses: visual colour matching, for example ammonia with Nessler's reagent.
• B.Sc. analytical chemistry: comparing light-coloured solutions against standards.
• Supervised demonstrations of qualitative and semi-quantitative techniques.

Standard Scope of Supply

The price line covers a single Nessler Cylinder. Stoppers, a second matching cylinder, racks, reagents, standard solutions and pipettes are not part of the supply; since tests use cylinders in pairs or sets, state the number of cylinders you need when you enquire.

Packing, MOQ and Lead Time

Whether you need one pair for a quality-control bench or a full set for every student group, send the quantity and the quotation will show packing, delivery time and price. Other school chemistry lab equipment in India, such as pipettes and flasks, can be priced alongside.

With an Importer-Exporter Code on record as a registered exporter, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. You can reach the team on the contact page, build a list in the enquiry cart, or read about institutional buying on the lab tender page.

Frequently Asked Questions

What is a Nessler cylinder used for?
It is used to compare the colour or appearance of a test solution with a reference solution by eye. Equal volumes go into matched cylinders, which are then viewed side by side under the lighting the method prescribes.

Is a Nessler cylinder the same as a measuring cylinder?
No. A Nessler cylinder is meant mainly for visual colour comparison, whereas a measuring cylinder is designed for measuring liquid volume. Laboratories usually keep both for different jobs.

How should the cylinders be cleaned?
Clean them promptly after each test so colour residues do not affect later readings, avoid abrasive brushes that scratch the viewing surface, and discard any cylinder that is chipped or cracked.

Who supplies the Nessler Cylinder?
It is supplied from Ambala, India by Science Lab Supplies. Pharmacy colleges, testing laboratories and contractors can order the cylinders in pairs or sets and add related glassware to one quotation.

Related Volumetric and Analytical Glassware

A limit test needs more than the comparison tubes: standard and test solutions are prepared by accurate volume and stored between sessions. These four items handle volume measurement, solution preparation and storage, so the complete analytical bench can be ordered together.

• Measuring Cylinder Glass — for measuring liquid volumes rather than comparing colour.
• Volumetric Flask — makes up standard solutions to an exact volume.
• Volumetric Pipette 5ml — transfers fixed volumes of reagents.
• Reagent Bottles Narrow-Mouth — store prepared reagents and standards.
