Accessory options for GD120-S12 bath
Lids and polypropylene spheres
Between 60ºC and 100ºC and below room temperature a lid or layers of polypropylene spheres should be used to help reduce evaporation/heat loss and avoid sample contamination. Above 100ºC a lid must be used.
Note: Polypropylene spheres are particularly useful where tall vessels need to be immersed.
Lids
LG12 gabled, hinged, removable stainless steel lid
Polypropylene spheres
PS20 pack of polypropylene spheres:
1 pack required
Rack systems and raised shelves
Grant custom designed racks and shelves enable you to optimise the available baths capacity. Raised shelves allow shallow vessels to be accommodated.
Racks
VR : - 2 VR racks per GD120-S12 bath
Tube size Number of tubes per VR rack
Ø 10-13 mm 65
Ø 16-19 mm 36
Ø 24 mm 23
Ø 30 mm 14
0.5 ml 102
1.5 ml 75
Raised shelves
Reduce the effective liquid depth to allow shallow vessels to be placed in the baths.
RS14 raised shelf
Accessory cooling systems
To allow systems to operate at or below room temperature by means of a cooling coil dipped into the bath. Designed for minimal impact on working area.
Refrigerated immersion coolers
Consist of a cooling coil connected to a refrigeration unit by a flexible pipe. Extract heat continuously, with the bath control unit controlling temperature.
C1G immersion cooler , temperature range 0 to 40ºC
Heat exchange coil
Designed to be attached to a supply of cooling tap water or a refrigerated circulator
CW5 heat exchange coil , temperature range 2ºC above coolant temperature
Accessory vertical turbine pumps
Required only where the application demands a higher pressure than that delivered by the GD120 internal pump to maintain flow. Note: When an accessory pump is fitted, the available working area is reduced.
Low noise, compact design. Supplied with pipe connections and special lid for fitting to tank, pipe bore 12.7 mm.
VTP1 - max. pressure 1000 mbar, max. flow 9 L/min
VTP2 - max. pressure 1650 mbar, max. flow 12 L/min
