Flexible programming, a wide temperature range and standard-compliant safety make this system the preferred choice over comparable devices.
High performance and efficiency for precise temperature control
The TX150 R series offers numerous well-designed features that ensure automated, flexible and safe temperature control. With five models and an intelligent design, the devices cover a wide range of applications - from sensitive sample incubation to demanding reaction iterations. Particularly noteworthy is the first-class temperature stability in accordance with DIN 12876, which ensures consistent quality of test results.
Important technical data at a glance:
- Temperature range depending on model: -25 °C to -47 °C (minimum), up to 100 °C (maximum)
- Precision: Temperature stability ±0.1 °C (DIN 12876)
- Pump capacity: max. 23 l/min, 530 mbar pressure for internal and external circulation
- Programmable sequences: storage of 10 programmes with up to 100 segments
- Full colour QVGA TFT display for intuitive operation and status monitoring
- Comprehensive safety features: over-temperature shut-off and float switch for low liquid level
- USB and RS232 interface for convenient control and data exchange
Other technical highlights include a resolution of 0.1 °C (up to 0.01 °C via Labwise), a timer function for precise process control (1 min to 99 h 59 min) and communication in five languages (EN, FR, DE, IT, SP). The connection for external temperature sensors and the option to configure relays for individual alarm messages offer maximum flexibility. The devices have a heating capacity of up to 1.9 kW (at 230 V).
The baths are made entirely of robust stainless steel and vary in volume from 5 to 20 litres, with practical working areas and well-designed dimensions for different test setups. Depending on the model, the weight also remains within the usual range for laboratory equipment (20-47 kg).
Certifications and standards
The devices in this series meet all the requirements of DIN 12876, offering tested safety for working with temperature-controlled liquid baths in the laboratory. This certified standard guarantees the highest standards in terms of operational safety, protection against overheating and reliable temperature control.
Specific applications in everyday laboratory work
-
Biotechnological processes: Incubation and temperature control of biological samples, e.g. in the cultivation of microbes or cell lines.
-
Chemical synthesis and analysis: Use for precise temperature control in reactors, during synthesis, distillation and titration, e.g. with solvents, buffer systems or polymers.
-
Pharmaceutical control: Use for stability testing, storage and conditioning of temperature-sensitive active ingredients and reagents such as insulin, antibiotics or vitamins.
-
Material testing and quality assurance: Temperature conditioning for the examination of physical properties, for example of plastic samples, adhesives or novel materials.
Thanks to the powerful pump, external applications such as the temperature control of jacket reactors or inline analysis systems are also reliably possible.
FAQ on use and function
How is temperature control achieved?
Through precise electronic control with external and internal calibration (two-point calibration). External probes allow direct temperature measurement in the sample for optimum control.
What safety mechanisms protect users and samples?
An adjustable overtemperature protection system and liquid level monitoring via a float switch prevent overheating or dry running.
Can custom programmes or sequences be saved?
Yes, up to 10 complex programmes with 100 segments each can be saved directly and executed repeatedly - ideal for recurring routines in everyday laboratory work.
Is external circulation possible?
The integrated pump allows direct temperature control of external systems with a high flow rate, enabling uniform temperature distribution and efficient cooling or heating of external reactors.
Summary
Grant's TX150 R series of cooled, circulating water baths offer a first-class solution for laboratory temperature control thanks to their wide temperature range, programmable control, DIN-certified safety and robust stainless steel construction. They combine high precision, reliable process safety and user-friendly operation - ideally dimensioned for applications in biotechnology, chemistry and pharmaceuticals where constant temperature control and versatile use are required.
