Aurius Spectrophotometers Have a Comprehensive Accessory Range Available

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.
