(C202CA7) Glass Standard Cuvette, 20 mm Path, 7 mL
Original price was: $27.00.$25.00Current price is: $25.00.
C202CA7 is a glass standard cuvette with a 20 mm optical path, 7 mL nominal capacity and a supplied lid for covered top access during routine handling. Its specified 350–2000 nm range suits visible to near-infrared work, and the listed price is for a pack of four cuvettes.
Description
C202CA7 is a glass standard cuvette for methods that use a 20 mm optical path and a covered sample opening. Its 7 mL nominal capacity gives a full-size sample chamber in a familiar rectangular body, while the supplied lid helps keep the top covered during handling between filling and measurement. The specified wavelength range is 350–2000 nm, so this option suits visible to near-infrared work rather than UV applications below 350 nm.

Choose this option
Choose C202CA7 when your method is set up for a 20 mm path and you want an open-fill cuvette supplied with a lid. That combination is useful when you need direct top access for pipetting and rinsing, but still want the sample opening covered during routine bench use. The nominal 7 mL capacity also makes this a practical choice for methods that are not built around micro-volume cells.
What makes this option different
- Lid-covered top opening gives direct access for filling and cleaning, then covers the opening during normal handling; it is not presented as a pressure seal.
- 20 mm optical path suits methods written for this longer path length rather than standard 10 mm cells.
- 7 mL nominal capacity provides a full-size sample chamber; nominal volume is not the same as minimum working volume.
- Fused integrated construction is the supplier’s stated build style for this cell, useful as a practical handling distinction when selecting a routine rigid cell body for repeated filling and rinsing, without implying a separate performance grade.
- 350–2000 nm specified range fits visible to near-infrared measurements and excludes UV work below 350 nm.
- Pack of four cuvettes per listed price unit for this MQ offer.
Using this cell
Fill from the top so the liquid level fully covers the beam area used by your instrument, and keep the same orientation for blank and sample measurements. The lid is useful once the sample is in place, but this remains an open-fill cuvette rather than a leak-tested or pressure-rated assembly.
The 7 mL figure is a nominal capacity for the cell, not a minimum working fill. If your method depends on low fill height or a tightly defined beam position, check that your actual liquid level will cover the light path in your instrument.
First-use check
Inspect the optical faces for chips, scratches, dust or residue before first use. Confirm that the cell seats squarely in the holder, then run a blank after filling to make sure the beam is fully covered and no bubbles remain in the light path.
Fit and optical alignment
The recorded external size is 22.5 × 12.5 × 45 mm for the uncapped cell body. Use those uncapped dimensions when checking holder seating, and leave additional top clearance for the lid because the overall closed height is not specified here.
Z Height is not established for this SKU. If your holder or spectrometer requires a defined beam-center height, verify that separately before ordering rather than relying on the body size alone.
Solvents and cleaning
Use non-abrasive cleaning methods and handle the optical faces carefully. The supplier describes this type for acid/alkali use, but the exact chemical limits for this SKU are not established here, so check your sample liquid, concentration, temperature, contact time and cleaning routine before use, especially for aggressive reagents or mixed-solvent work.
