Accessories
Cuvette Holder
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.
Astra CH1 Cuvette holder, 1cm pathlength,
complete with collimating lenses
Astra FC1 Flowcell 1cm pathlength,
constructed in Peek with collimating lenses and
demountable windows wavelength range from
230 to 2,200nm
Astra FC4 Flowcell 4cm pathlength, constructed
in Peek with collimating lenses and demountable
windows wavelength range from 230 to
2,200nm
Flow Cell
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.
Colour Measurement
AstraNet offers a six-around-one reflectance
probe for small sample areas, this accessory
can be used to measure the colour of solid
objects over the wavelength range 400-700nm.
Dip probe
Immersion probes allow direct absorption
measurements of liquid samples by simply
immersing the probe tip into a suitable vessel
containing the sample. Optical pathlengths from
2 to 40mm are available as interchangeable
screw-in tips. Reactions can be monitored
directly in a vessel thanks to the very fast
scanning speeds of the spectrometer.
Additionally, immersion probes can be installed
directly into sample streams, such as steel pipes
in industrial plants, for monitoring and control
purposes.
