-
Volumes: 5 l, 12 l, 20 l variants, each with a robust stainless steel container
-
Temperature stability & uniformity: ±0. °C (DIN 12876-compliant), guarantees constant conditions for sensitive processes
-
Heating power: 1.3 kW (230 V) or 1.4 kW (120 V) for rapid temperature changes
-
Maximum flow rate: approx. 23 l/min - ideal mixing and external circulation possible
-
Display: Four-digit, easy-to-read LED display for target and actual values
-
Alarm management: Visual and audible alarms, over-temperature shutdown, configurable floats for liquid level protection
The tanks are made of high-quality stainless steel and are available in various sizes. The most compact model (R1/R2) has a volume of 5 l, while R4 with 20 l and R5 with 12 l cover an even larger sample spectrum. The external dimensions vary accordingly, with all models guaranteeing ergonomic handling, easy cleaning and reliable long-term durability. Depending on the tray, the usable liquid depth ranges from 85 to 180 mm - ideal for larger vessels as well.
Other features include a four-button control unit, a USB port for data transfer and optional PC connectivity with Labwise software, which offers functions such as programming, real-time graphics and comprehensive data acquisition. Users also benefit from two calibration points for customisation and quality assurance.
Safety features and standards
Safety is a key focus: in addition to the adjustable overtemperature protection function, a float ensures level control. The entire series is DIN 12876-certified and meets the quality requirements of modern laboratories: maximum operational safety, low maintenance and reliable alarm functions protect personnel and samples. Applications in research, development and quality control
The flexible temperature ranges of the TC120 R series make it the first choice for a wide variety of laboratory processes:
-
In biotechnology: Incubation and cultivation of cell lines, temperature-controlled fermentation processes (with buffer substances, cell culture media, if necessary)
-
Chemical synthesis: Precise temperature control for reaction control, temperature control of solvents such as acetone, methanol or ethanol, reflux cooling, extraction processes
-
Pharmaceutical analysis: Stability testing of drugs and formulations, determination of melting points, quality assurance under reproducible conditions
-
Food analysis: Reference measurements, for example in fat and protein analyses (e.g. milk with butyrometers), pasteurisation tests or temperature control in enzyme assays
The powerful circulation pump enables both internal and external applications to be operated reliably, for example, temperature control of reactors, cooling of analysis devices or sample cells.
FAQs
How are the temperature processes controlled and monitored?
Operation is via an intuitive LED display with four buttons. Parameters can be entered, saved and monitored graphically either on the device or via PC using Labwise software.
Which temperature fluids are suitable?
Pure water can be used for standard applications, mixtures with propylene glycol for low temperatures and special silicone oils for applications above 8 °C. The selection depends on the desired temperature range and application.
How is calibration implemented in everyday laboratory work?
Using two-point calibration, both internal and external temperature monitoring (via optional probe) can be optimally adjusted to achieve maximum measurement accuracy.
Is there a way to alert in critical situations?
Yes, the series offers audible and visual alarms. The alarm parameters can be set individually; there is also a reliable overtemperature protection and a float to control the liquid level. Can custom programmes be stored? Optional - With Labwise, up to 10 programmes with 100 segments each can be stored and applied as needed. This facilitates recurring processes and test series.
Conclusion
Grant's TC120 R series refrigerated circulating water baths are the ideal solution for research and quality control in laboratory environments where accuracy, reliability and flexible temperature control are required. Thanks to extensive safety features, modern communication technology and compliance with relevant standards, a wide range of processes and experiments can be carried out efficiently and safely. The robust stainless steel construction, intuitive operation and intelligent control options guarantee a sustainable investment in laboratory equipment - for the demanding requirements of today and tomorrow.
