31B-Q Style Cylindrical Quartz Cuvette short path low volume
The Type 31B range small volume cuvettes have path lengths 0.01mm to 5mm, with a sample compartment aperture of 13mm. The structure of this 31B-Q cylindrical cuvette allows for lower volume usage as compared to the requirements of the Type 31 cells. Please note when filling cylindrical cells, to avoid damage to the windows, do not fill cell to the top. Leave an air gap otherwise the windows will be broken by the hydraulic pressure of the stopper being inserted. PTFE stoppers are supplied with these cells as shown in drawing below.
