Accessories: Flow Cell and Cuvette Holder

Flowcells

Offering a serious alternative to the immersion probe, flowcells are especially useful in situations where the sample may contain particulates.

AstraNet offers a range of both low and high pressure flowcells, with pathlengths from 1 to 100mm, measurements are not affected by turbulent flow.

The flowcells are supplied with integrated collimating lenses and windows and connection to the input and output fibres is via simple SMA 905 connectors. 

Astra FC1 Flowcell 1cm pathlength, constructed in Peek with collimating lenses and demountable windows wavelength range from 230 to 2,200nm

Astra FC4 Flowsell 4cm pathlength, constructed in Peek with collimating lenses and demountable windows wavelength range from 230 to 2,200nm

Cuvette holders

Fixed 10mm pathlength holders are offered to allow the use of standard laboratory cuvettes for measuring the absorption of liquid samples.

A variable pathlength holder provides for pathlengths from 10 to 100mm.
