Refrigerated baths and circulators, Optima™
循环水浴 开放式循环系统 Heating/Cooling Circulators
Grant low temperature circulators provide a source of precision cooling for most low temperature applications.

  • T100 temperature range: 0 to 100 °C with refrigeration unit
  • TC120 temperature range: −25 to 100 °C with refrigeration unit
  • Pump for external circulation, an audible and visual alarm and adjustable over-temperature cut-out (TC 120 only)
  • Stability and uniformity ±0,1 °C at −10 °C

General purpose thermostats – T100 and TC120:
Digital microprocessor controlled T100 and TC120 thermostats feature an easy to use rotary dial and two function keys for quick temperature setting and menu navigation. Units feature a bright, easy to view four digit display, three programmable temperature presets, low liquid protection, over-temperature cut-out, visual alarm, countdown timer and user calibration facility for optimal accuracy.

They are suitable for use in both open and closed loop circulation (i.e. remote vessel open or closed). R2, R3, R4 and R5 models include a drain tap. The four Grant Optima™ thermostats can be combined with the five Grant refrigeration units to provide a range of models to cover basic through to sophisticated needs. Grant also offers a choice of two ready assembled low temperature refrigeration kits (LTC models) which have the Optima™ mounted on the refrigeration unit as a ready to use system with an additional years warranty (total 4 years).

Advanced thermostats – TX150 and TXF200:
TX150 and TXF200 thermostats feature a full colour QVGA TFT screen displaying actual and set temperature and clear status icons. The QVGA TFT screen in combination with the easy to use dial and function keys allows rapid navigation through the intuitive menu system. Both units have an RS232 and USB interface and can be programmed via remote PC or laptop using Grant’s versatile Labwise™ software (software optionally available). Additional features include countdown timer, adjustable over-temperature cut-out, visual, audible and programmable high and low temperature alarms. The TX150 has the capacity to store one programme with 30 segments. The TXF200 can also be programmed via the user interface and can store up to 10 programmes containing 100 segments. The programming interface includes set target temperature with a choice of time to target temperature or temperature ramp speed and an additional programmable relay for on/off control of refrigeration units.

TX150 and TXF200 temperature range: Ambient −47 to 100 °C with refrigeration unit (R unit dependent)
Pump for external circulation, an audible and visual alarm and adjustable over-temperature cut-out
Stability at −10 °C is ±0,1 °C
External PT1000 temperature probe socket
Five-point user calibration of internal and external probes

Maximum pump capacities:
TC120 16 L/min, 210 mbar
TX150 18 L/min, 310 mbar
TXF200 22 L/min, 530 mbar variable speed

Delivery information: LTC models are supplied with insulated tubing and clips, and include an additional years warranty. For details of the full range of models and accessories please see the VWR website.

Caution: Cooling capacity, defined at 20; 0; −20 and −40 °C in an ambient of 20 °C.
