Before You Order
- Glued (cemented) construction — neutral samples only. The quartz body is inert, but the cement is not: strong acids, strong alkalis, HF and most organic solvents will attack the bond.
- Match the centre height. This cell has a 15 mm centre height. If your instrument beam is fixed for a standard 10 mm cell it may miss the sample window entirely.
- Set the slit width. This cell needs a 2 mm instrument slit; without it the beam reads cell wall or air.
- Not every instrument is compatible. Confirm beam geometry and sample-compartment height with your instrument manufacturer before ordering — or send us the make and model and we will check for you.

100µL Quartz Fluorescence Ultra-Micro Cuvette (10mm Path) - Frequently Asked Questions
What sample volume do I need for an ultra-micro cuvette?
This cuvette needs a minimum of 100µL. The internal chamber height is 15mm with 2mm slit width, so even at 100µL the light path is fully filled. For smaller samples (down to 20µL), see our 20µL variant.
Is this cuvette suitable for DNA and protein quantification?
Yes. The four-way optical windows and JGS1 fused silica construction make it ideal for fluorescence assays including PicoGreen, RiboGreen, Hoechst 33258 DNA quantification, and Bradford/BCA protein assays. For UV absorbance at 260nm/280nm, the JGS1 material provides >83% transmittance with low autofluorescence.
How do I clean an ultra-micro cuvette without scratching?
Rinse with deionized water, flush with 1% laboratory detergent solution, then rinse with isopropanol. Use only soft-tipped pipettes or syringe needles to dispense - never insert forceps or hard objects. Air-dry or use lint-free wipes. For full protocol see our cuvette cleaning guide.
