Other relevant features: The device can be individually recalibrated with a maximum of two calibration points and supports three temperature presets for frequently used setpoints. With a liquid level warning system, adjustable over-temperature shutdown and robust safety features, operation is securely protected even during sensitive reactions or continuous use. The T100 series features a compact housing and tank design, with dimensions optimally adapted to the respective volumes and areas of application.
The stainless steel model (ST series) offers improved chemical resistance to common laboratory chemicals such as buffer solutions, hydrogen peroxide or ethanol, while the plastic models (P series) offer an economical solution for standard applications.
Special features
The series scores with the following special features that make everyday laboratory work easier:
- Precise electronic temperature control and stable, even water circulation
- Individually configurable liquid level monitor with float mechanism
- Uncomplicated operation via an easy-to-read, 4-digit LED display
- Robust plastic or stainless steel baths for maximum flexibility in the choice of chemicals
- Various safety mechanisms for uninterrupted and safe temperature control of sensitive substances
- Option of two-point recalibration for accurate temperature measurement
Certifications and standards
The water baths comply with the requirements of the DIN 12876 standard for temperature control, stability and uniformity of liquid temperature control baths. They therefore meet key criteria for standard-compliant laboratory operation in terms of accuracy, reproducibility and traceability of temperature control.
Typical applications in scientific laboratories
Thanks to their precise temperature control and reliability in long-term use, these devices are particularly suitable for the following laboratory procedures:
-
Incubation of biological samples such as cell cultures, bacterial suspensions and enzyme reactions (e.g. restriction digestion with buffer solutions, PCR reactions)
-
Chemical analyses and syntheses where constant, reproducible temperature control conditions are essential (e.g. control of exothermic reactions, synthesis of polysaccharides and peptides)
-
Materials science testing, including resistance and ageing tests on plastics, elastomers and coatings at defined temperatures
-
Quality control in the food and beverage industry, including pasteurisation, temperature control and testing of fruit juices, dairy products or sample extracts
The models are also popular in the pharmaceutical industry and biochemical research for dissolution, solubilisation or stability testing of active ingredients and reagents such as SDS, Tris-HCl, ethanol or glycerine.
FAQ: Important questions and answers about use
How is the temperature measurement recalibrated?
The two-point recalibration is carried out directly on the controller and can be set for internal temperature probes. This ensures maximum measurement accuracy for changing applications.
Can the water baths be used for external circuits?
Thanks to a powerful, adjustable pump, external circulation operation is possible, e.g. for cooling or temperature control of reaction vessels outside the water bath.
What safety standards are implemented?
All models have a liquid level sensor (float switch) and a fixed overtemperature protection system to ensure safe operation at all times and prevent damage.
Are the water baths suitable for media containing solvents?
The stainless steel tank models can be used with many common solutions such as buffers, water, ethanol or other moderately aggressive chemicals (no concentrated acids/bases).
How flexible is the choice of language and display?
The T100 series models use a 4-digit LED display with simple parameterisation - various language options are not available on the device for international use, but the user interface is intuitively designed.
Which programmes can be used to control the temperature?
Three temperature setpoints can be stored, and the desired target temperature can be selected directly depending on the application.
Conclusion
The GRANT Optima T100 series circulating water baths combine first-class precision, excellent long-term stability and a comprehensive protection mechanism, as required by professional laboratories today. Thanks to their flexible configuration, wide range of models and maximum reliability, they are establishing themselves as the standard solution for all temperature control tasks in scientific and industrial environments.
