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. It suits limit tests and visual comparisons in pharmacy, chemistry and water-analysis practicals. Science Lab Supplies, a laboratory glassware supplier in India based in Ambala, can send it to schools, pharmacy colleges, testing laboratories, tender contractors and dealers.

Specifications

The rows below break the Nessler cylinder down fact by fact. In short, it 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; the comparison is visual, with no electronic measuring system.

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, colour checks in water analysis and introductory lessons on semi-quantitative analysis all depend on pairs of these tubes viewed under identical conditions.

• B.Pharm pharmaceutical analysis: limit tests for chloride, sulphate and iron, with standards measured by a Graduated Pipette.
• 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, adding reagent drop by drop with a Glass Dropper Pipette 6.
• 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. Ask for cylinder pairs or sets via the contact page, keep a running list in the enquiry cart, and check the lab tender page if the order is part of a public tender.

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. The two do different jobs and can be quoted together.

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

Who supplies the Nessler Cylinder?
Science Lab Supplies dispatches it from Ambala in Haryana. Pharmacy colleges, testing laboratories and contractors can order the cylinders in pairs or sets and add standards glassware, pipettes and reagent bottles to the same quotation.

Related Colour Comparison and Volumetric Glassware

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

• Measuring Cylinder Glass — transparent graduated cylinders offered from 10 mL to 500 mL.
• Volumetric Flask — borosilicate 3.3 flask for bringing a solution to a defined final volume.
• Volumetric Pipette 5ml — fixed-volume pipette that is not graduated to the tip.
• Graduated (Measuring) Tubes with Stoppers — glass tubes in 10 ml and 25 ml capacities.
• Colorimeter Photo Digital — works with test tubes and a rotating disc of eight filters to find concentration by colour.
• Reagent Bottles Narrow-Mouth — colourless glass bottle with a frosted stopper for prepared reagents.
• Bottles of Dark Glass with Stoppers for Reactants — amber glass that reduces UV transmission, 60 ml to 500 ml.
