Description

C202CR4 is a JGS1 quartz large-window cuvette for UV/Vis work with a 20 mm optical path and a 42.4 mL nominal capacity. Its open-top body gives direct access to the sample chamber, and this option is specified as a flat-bottom version, which is useful when you need that stated profile as part of your cell selection. The Two-Way Light layout supports transmission measurements through the opposing optical faces.

Choose this option

Choose C202CR4 when your method calls for a 20 mm transmission path and a larger upright sample chamber than compact cuvette formats provide. The nominal 42.4 mL capacity suits workflows that need a fuller liquid volume in the cell, while the open top makes filling, rinsing and visual inspection straightforward from above. This listing is also the flat-bottom option, so keep that profile requirement separate from path length and overall body size when matching the cell to your setup.

What makes this option different

20 mm optical path for UV/Vis methods built around this longer transmission distance.
42.4 mL nominal capacity in a large upright chamber for methods that use a higher sample volume in the cell.
Open-top access for direct pouring, pipetting, rinsing and chamber inspection from above.
Two-Way Light geometry for transmission through two opposing optical faces.
Flat-bottom version for applications that need this specified profile as part of the cell format.
Large internal region with listed internal dimensions of 50 × 20 × 53 mm for planning filling space and chamber access.

Using this cell

Fill the cell from the open top and make sure the liquid covers the sample region used during measurement. Before reading, check for bubbles, droplets or streaks across the optical path, especially after pouring or decanting.

The 42.4 mL figure is the nominal capacity of the cell, not a minimum working volume. If your method uses a lower fill level, check separately that the beam still passes through a fully covered sample region.

First-use check

Inspect the optical faces and chamber when the cell arrives, then rinse before first use. Place the empty cell in your holder to confirm seating and clearance, and run a blank before preparing a full sample for measurement.

Fit and optical alignment

The listed external dimensions apply to the uncapped cell body: 54 × 24 × 55 mm. Internal dimensions are 50 × 20 × 53 mm. Use these dimensions to check holder clearance and surrounding space for handling, rather than assuming fit from the 20 mm path length alone.

Z Height is not listed for this SKU. If your spectrometer or accessory depends on a defined beam-center height, confirm that separately before ordering instead of using the overall body height as a substitute.

Solvents and cleaning

This cuvette is made from quartz with a supplier-described powder-fused construction. For use and cleaning planning, treat this as a quartz cell whose exact chemical limits for this SKU are not established here, especially if your method involves aggressive solvents or mixed cleaning routines. For general fabrication background, see Compare fabrication methods.

Do not use hydrofluoric acid on quartz. Avoid hot strong alkalis and abrasive cleaning methods that can damage the optical surfaces.

Included with this option

1 cuvette per listed price unit.

Availability and ordering

Order this specification directly, or contact us to check current availability and dispatch timing. If temporarily unavailable, additional preparation or production time may be needed. For a required delivery date, contact us before checkout; preparation or production is separate from carrier transit and customs clearance.

Discuss a custom version

If you need a different body size, optical path, chamber format, closure style or holder fit, we can review a custom JGS1 quartz version separately from this listed SKU. Send your drawing or holder details, key dimensions and sample conditions through the contact page and refer to part number C202CR4.
