-35°C to 250°C
Three different capacities available; 5, 7 or 12 litres
Temperature stability; ±0.005°C depending on choice of control unit
Fully insulated bath for excellent heat retention
Analogue or digital temperature selection, depending on choice of control unit
Includes cover, lid and bridging plate

When temperature calibration is required the compact liquid baths offers excellent stability over
the entire temperature range. The LCBs can be also be used for external circulation to maintain
temperatures of samples in viscometers, photometers, refractometers, fermenters and other t
reaction vessels.
All models of LCB offer exceptional thermal stability from -35ºC to 250°C. The baths are
fully insulated on all sides and base and are fitted with a cooling coil for connection to a cold
water supply for use at temperatures around ambient. The minimum temperature achievable
is -35°C when a Dip or Flow Cooler is added to the system.* For the full specifications of the
thermoregulators see pages 24 and 25.
Each bath is supplied complete with lid, drain tap, carry handles , a cooling coil and hole with
bung to position a certified sensor.
The TechneWorks software package is available for the TU-20 thermoregulators free of charge
from www.techne.com (see page 11 for details).
