The 63 series has been specifically designed to enable a wide range of accessories to be easily fitted and used. To increase productivity Jenway offer a four position rotary cuvette holder. To accommodate various sample volumes there are a wide range of passive accessories available including an adjustable cuvette holder which can hold cuvettes between 10 and 100mm; a test tube holder for test tubes with diameters between 16 and 24mm; and for small sample volumes there is a micro-cuvette holder with a reduced aperture.

Where temperature control is important Jenway offer a water heated cuvette option which requires a water bath and circulator (not supplied). For reproducible samples volumes Jenway offer an external sipper pump system which can be programmed to deliver controlled and reproducible sample volumes into the chamber of a flow through cuvette along with air and segmentation rinse cycles.
