Description

C212CR is a large-window JGS1 quartz cuvette for UV/Vis measurements with a 21 mm optical path and a 45 mL nominal capacity. Its open-top body gives direct access to a broad upright chamber, which is useful when you need to fill, rinse or inspect the sample area from above rather than work through a narrow opening.

This is a Two-Way Light transmission cell, so selection is centred on a straight optical path through two opposing faces. The larger body format also matters at the holder stage: it can suit methods that use a larger upright sample region, but it needs more space than smaller standard-format cells.

Path Length: 21 mm
Sample Volume (Nominal): 45 mL
Opening Configuration: Open Top (Cell Body)

Choose this option

Choose C212CR when your method calls for a 21 mm transmission path and you want direct top access to a large upright sample chamber. The 45 mL nominal capacity and broad internal region make this option practical for filling, rinsing and checking the liquid condition by eye, while the quartz body supports UV/Vis use across the stated wavelength range.

What makes this option different

Open-top access lets you add and remove sample directly from above, with clear access for rinsing and routine visual checks inside the chamber.
Large upright chamber provides a broad internal sample region instead of a compact narrow-body format, which can be easier to handle when the method uses a larger liquid volume.
21 mm optical path suits methods built around this transmission length rather than the shorter paths used by many small cells.
Two-Way Light layout is intended for straight-through transmission measurements through opposing optical faces.
Powder-fused construction is the supplier’s stated build style for this option; in practical use, it is a structural selection detail rather than a claim of a monolithic body, measured tolerance or universal solvent resistance.
JGS1 quartz material supports UV/Vis use over the stated 200–2500 nm range for this cell format.

Using this cell

Fill the cell from the open top and make sure the liquid level covers the beam region used by your instrument. Before measurement, remove visible bubbles and keep the optical faces free from fingerprints, streaks and dried residue.

The broad chamber gives more room for direct pouring, pipetting and rinsing than a compact narrow opening. If your method depends on repeatable positioning, keep the same cell orientation for blank and sample runs.

First-use check

Inspect the chamber and optical faces on arrival, rinse before first use, and place the empty cell in the holder to confirm stable seating and beam access. Then run a blank before introducing sample.

Fit and optical alignment

The listed external dimensions apply to the uncapped cell body: 46 × 27 × 70 mm. Internal dimensions are 40 × 21 × 67 mm. These body dimensions are important when checking holder clearance, especially if your instrument is arranged around a smaller cuvette format.

Z Height is not specified for this item. If your holder or spectrometer requires a defined beam-centre height, confirm that separately before ordering rather than using the overall body height as a substitute.

Solvents and cleaning

This cuvette is made from quartz. Do not use hydrofluoric acid on quartz. Avoid hot strong alkalis and abrasive cleaning methods, and wipe the exterior optical faces gently with a non-abrasive optical tissue.

Specific chemical compatibility limits are not listed for this exact SKU. If your process involves aggressive solvents or long contact times, check suitability for the complete cell and your actual conditions of use. For general fabrication background, see MQ Cuvette Fabrication Glossary.

Included with this option

1 cuvette per listed price unit. If you need a supplied closure or other accessory, contact us before ordering.

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, path length, chamber format 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 C212CR.
