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 8.5 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 1 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.

Frequently Asked Questions
It is designed for low-volume fluorescence spectroscopy, DNA/RNA quantification, protein assays, and other applications where sample volume is limited to 20µL.
The 8.5mm center height defines the vertical position of the sample window relative to the instrument base, ensuring compatibility with most fluorescence spectrometers.
This cuvette has a 1mm slit width, which controls the illuminated sample volume and helps optimize signal intensity.
Yes, it is made from JGS1 fused quartz with >80% transmittance from 200nm to 2500nm, suitable for UV-Vis and fluorescence measurements.
Glued cemented windows are recommended for neutral aqueous samples only. For aggressive organic solvents, choose a fully fused quartz cell.
