Overview
A UV-VIS absorbance bench needs square quartz cells like these, which the title describes as sealable cuvettes for a spectrophotometer. Quartz passes light across the stated wavelength range, and two cells arrive in the pack.
The stated range is wide and quartz covers the ultraviolet region where plastic cells fail, which is the case for choosing these over disposable cells. The seller states a size but not a clear path length, so the match to a holder is left to the buyer.
Who it's for
Teaching and research labs that run absorbance studies and need quartz cells in a standard looking square format. Buyers with a strict holder size or matched cell requirement should ask the seller for the path length.
Pros and cons
- Quartz for UV transmission
- Wide stated wavelength range
- Two cells in the pack
- Path length not given as a number
- Matched pair status unstated
- Lid details unstated
Performance notes
Quartz transmits ultraviolet light that ordinary plastic or glass absorbs, so readings in that region are possible. Fingerprints and scratches on the optical windows distort absorbance, so handling and cleaning matter more than anything else.
