Lids

Between 60ºC and 100ºC and below room temperature a lid or layers of polypropylene spheres should be used. Above 100ºC a lid must be used. Lids help to reduce evaporation and heat loss, and to avoid contamination of samples. Hinged lids can be opened to a stable, vertical position, or lifted off completely.

Polypropylene spheres

Polypropylene spheres are an alternative to lids for temperatures up to 100ºC, allowing easy access to vessels in the bath, and are particularly useful for tall vessels.

Rack systems

Our range of robust, stainless steel racks enable you to make the best use of the available bath capacity.

Raised shelves

Raised shelves reduce the effective liquid depth to allow shallow vessels to be placed in the baths. The effective liquid depth may be between 0 and 90 mm in 12 or 18 litre baths, and between 0 and 50 mm or 85 and 135 mm in 26 and 38 litre baths.

Accessory cooling systems

Cooling systems allow thermostatic baths, circulators and immersion thermostats to operate at or below room temperature, by means of a coil dipped into the bath. The coil is made of nickel-plated copper, and is designed to fit in the bath such that it doesn’t impinge on the working area (except S5).

CG refrigerated grant immersion coolers: consist of a cooling coil connected by a flexible pipe to a refrigeration unit, which is housed in an outer case; immersion coolers extract heat continuously, with temperature control carried out by the bath’s control unit.

CW5 heat exchange coil: is designed to be attached to a supply of cooling tap water, or a refrigerated circulator.

External probe

For use with GR150 and GP200, for remote temperature control. FF17 flexible nylon probe has a very fast response; 100mm long, 4.5mm dia. LL17 robust stainless steel probe, slower response; 125mm long, 5mm dia. Fitted with two metres of cable. Special probes can be supplied for use in corrosive liquids.

Remote switching device

The RSD remote switching device can be used by the GR150 and GP200 models to control, by switching on and off, any mains powered appliance (up to a maximum of 8 Amps). This can be programmed on the GR150 and GP200 controllers under the alarms - relay section of the Navigator control menu, or alternatively with Labwise software. The GR150 can control one relay and the GP200 can control two. A separate RSD is required for each relay on the GP200.
