Micro Sampling
For analytical measurements of minute samples, such as the purity
of nucleic acid in a biological sample, or samples prepared with
costly reagents, measurements may be made on samples as small as
50µl, or even less, using a special cell and holder.
The optical system provides a small image at the sample position
so that a large proportion of the available energy passes through
the sample, giving accurate, low noise measurements with excellent
linearity.

Micro Sipette Sampling
For rapid measurement of samples as small as 300µl with low
cross contamination this is the ideal sampling system.
Without cell handling all measurements are made in the same cell,
enhancing accuracy and eliminating breakages.
The pump, mounted in the sample compartment, is controlled by the
instrument with control information and data on screen. Fully documented
printouts are provided.

Ultra-Micro Sampling
For the ultimate in small sample measurement, a special precision
cell holder is available which accommodates a pipette loaded cell
with a 10µl chamber volume and a 10mm pathlength. A similar
cell is also available offering a chamber volume of 5µl with
a 5mm optical pathlength.

Sampling Accessories
A complete range of sampling accessories is available, some of
these are shown and include cell changers, 50µl and 5µl
cell holders, film holder and microcell changer.

Thermoelectric Temperature Control
The CE2024 controller provides temperature control for a single
cell, sipette cell or four cell changer. Water cooling is provided
for work below ambient. Temperature programming is also provided
for thermal melt experiments.

Water Thermostatting
Water thermostatted holders are available for single cells, sipette
cells, long pathlength cells and the four cell changer. A holder
with pipe port and special lid fitted is shown here.

Automatic Cell Changers
Four, six and eight cell changers are available. A long pathlength
holder is available for four cells. Water and Thermoelectric temperature
controlled holders may also be used.
