Liquid Calibration Baths

Please note: thermoregulator temperature control units are purchased seperately. See "Further Information" links in left margin.

The Techne® liquid calibration bath (LCB) series offer compact, accurate and reliable liquid baths which can be used for external circulation or temperature calibration of thermal sensors.

• -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 offer 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 reaction vessels.

All models of LCB offer high pump performance and exceptional thermal stability from -35°C 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 Flow Cooler is added to the system.

Each bath is supplied complete with lid, drain tap, carry handles, a cooling coil (with bung) and hole to position a certified sensor. The TechneWorks software package is available for the TU-20 thermoregulators free of charge from www.techne.com.

LCB Probe holder
The new FBCAL7PH LCB probe holder is an accessory designed to allow multiple probe positioning and calibration within the LCB.
It can be used for 5, 7 and 12 litre baths and acts as a lid as well as a probe holder.
The Probe holder has spare mounting studs to suit all 3 bath models.

The probe holder has holes for 10 off probes to Ø12.5mm and also 8 off probes to Ø6.5mm.

Please note: for Liquid Calibration Baths to operate, a thermoregulator is required. The thermoregulator must be purchased separately because there are 4 models to choose from. To determine which thermoregulator is most suitable please click here
