With the adjustable overtemperature shutdown and low liquid protection function, safe long-term operation is guaranteed - even with complex multi-stage processes and sensitive samples.
Typical areas of application and specific uses
The GRANT JB Academy water bath is used in all areas where consistent and precise temperature control is essential. It is an indispensable tool for
-
Molecular biology: Performing enzyme reactions, optimal conditions for PCR, restriction digestion or DNA ligation. Heat-sensitive substances such as enzymes (e.g. DNA polymerases), plasmids or buffers also benefit from the accuracy.
-
Pharmaceutical development: Stability testing, solubility determination and quality control of active ingredients or reference substances at a constant temperature.
-
Materials research: Temperature-dependent viscosity measurements, expansion analyses, investigation of polymers or additives.
-
Food analysis and beverage industry: Checking shelf life, recipe development and sensory tests through targeted heating or cooling of samples such as milk, fruit juices, emulsions or fermentation preparations.
Precise control and high programmability also make it the ideal choice for empirical test series, comparative studies and long-term studies.
FAQs
How is calibration performed to ensure accurate temperature results?
Two-point calibration can be performed directly on the device for internal and external probes (TXPEP, TXSEP), enabling application-specific fine adjustment.
What safety features protect my samples?
The device has low liquid protection (float switch) and an individually adjustable over-temperature shut-off to prevent damage from evaporation or overheating. Warning messages are signalled visually and acoustically.
Can operating data be recorded electronically?
Yes, all models are equipped with a USB interface for PC connection. The optional Labwise software also enables comprehensive monitoring, data storage and graphical evaluation.
Which media can be used in the water bath?
In addition to water, buffer solutions, buffered salt solutions, ethanol-water mixtures or special laboratory media can also be safely temperature-controlled, depending on the experiment and temperature requirements. For particularly low temperatures, the use of suitable cooling media is recommended.
How flexible are the programming functions?
Up to 10 programmes, each with up to 100 segments (temperature/time), can be stored per device. Ideal for complex processes and automated sample thermostatting.
Conclusion
The versatile laboratory water bath from Grant Instruments sets standards for precise temperature control in modern laboratories. For professional requirements in research, quality control and development, it offers safety, efficiency and intuitive operation in a robust, durable system. Whether in a university environment, the pharmaceutical industry or food analysis, this water bath guarantees reproducible results and maximum reliability, even for demanding tasks.
