Sample cylinder Nessler Cylinder

Overview
At Osmosis Scientific, the Nessler cylinder for colour comparison (Class A) is manufactured from borosilicate 3.3 glass with clear, calibrated graduations for fast, repeatable visual colour matching. Available capacities: 50 mL and 100 mL. Supplied in packs of 10 with defined subdivisions and Class A tolerances suitable for routine water testing, chemical comparisons and QC workflows.

Sizes & tolerances (Class A)
50 mL — subdivisions: 25 mL & 50 mL; tolerance ±0.4 mL; pack of 10; SKU: NCC-A-0050
100 mL — subdivisions: 50 mL & 100 mL; tolerance ±0.8 mL; pack of 10; SKU: NCC-A-0100

Applications
Nessler cylinders are used for side-by-side visual colour comparison where consistent viewing depth provides reliable sample comparison. Typical applications: water colour checks, comparative chemical analyses and laboratory QC procedures requiring repeatability.

Why Class A matters for colour comparison
Class A tolerances reduce volume variation between cylinders, minimising visual differences caused by small fill discrepancies and supporting more consistent results in routine testing and reporting.

How to use (best practice)

• Use matched cylinders for side-by-side comparison and fill exactly to the mark.
• Compare against a neutral white background with consistent, diffused lighting for clearer colour assessment.
• Rinse thoroughly between samples and avoid abrasive cleaners that can scratch the glass and affect clarity.

Packaging & ordering
Supplied in packs of 10 for both capacities with clear subdivisions for rapid checks. For pricing and availability contact Osmosis Scientific or authorised distributors via official ordering channels.
