Sipette System

The sipette system shown in the photograph may be used to advantage when a number of samples have to be measured in sequence. All measurements are made in the same cell improving accuracy while cell handling and breakage are avoided. The Sipette pump mounts inside the sample compartment and operates under control of the spectrophotometer microprocessor system. Samples after measurement may be returned and saved, or pumped to waste.

Multi-Cell Sipette System

A cell changer designed to accommodate three cells, of 10mm, 20mm and 50mm pathlengths, connected in series speeds up the change between cells of different pathlengths when using a sipette system. This avoids cell handling and breakage.

Batch Sampling

Where large numbers of similar samples are to be measured, a batch sampler is available for up to 100 samples. The pump for the system is sample compartment mounted and under the instruments internal system control.

Automatic Cell Changers

For automatic measurements cell changers are available for 4, 6 or 8 cells and may be fully programmed for measurements.

A wavelength programme for up to 10 wavelengths is also available and may be used with a single cell or combined with a cell changer for a cell and wavelength program.

The sample changers are shown above together with a photograph of the 6 cell changer fitted to a spectrophotometer.
