The black wall really cuts stray light for our low-volume fluorescence reads. Pairing is consistent and the PTFE lid seals well. Exactly as described.

Perfect for tiny sample volumes — the 350 μL version saves a lot of reagent. Windows are clean and plano-parallel. Will reorder.

Good value micro cuvettes. We use the 1750 μL ones for routine UV and they perform exactly as expected. Arrived well packed.

Transmittance is solid for the price and the glue joints look clean. The black wall makes a visible difference versus clear micro cells.

Black Wall Quartz Micro Cuvette (4-Port 50µL, Center Height 8.5mm) - Frequently Asked Questions
What does the black wall on this cuvette do?
The blackened side walls absorb stray light instead of letting it pass through the cell body, which suppresses light piping and scattered-light interference. This makes the 50µL cuvette well suited to low-volume fluorescence measurements where a clean signal-to-noise ratio matters. Only neutral (non-fluorescent) samples should be used.
What is the minimum sample volume for the 50µL cuvette?
This cuvette is rated for a sample volume of 50µL at 8.5mm center height. At the rated volume the light path is fully covered, giving reproducible readings run after run. If you need a different sample volume, pick the matching variant from the related products below.
Can I use a black wall cuvette for UV absorbance measurements?
Yes. The four clear windows are JGS1 fused silica with transmittance above 80% from 200 nm to 2500 nm, so the cell can be used for UV-Vis absorbance as well as fluorescence. Keep in mind the black walls only control stray light – use neutral samples and stay below the maximum operating temperature of 100°C.
How do I clean a black wall micro cuvette without scratching?
Rinse immediately with deionized water, flush with 1% laboratory detergent solution, then rinse with isopropanol. Use only soft-tipped pipettes or gel-loading tips to fill – never insert forceps or hard objects. Air-dry inverted or blot with lint-free wipes. For the full protocol see our cuvette cleaning guide.
