Safety standards and certifications
The integral safety features include reliable overheating protection, which immediately detects uncontrolled temperature rises and protects the system. With its safety class 2 rating and CE marking, the SB-35 complies with all relevant European directives for safe laboratory operation. The corrosion-resistant design minimises contamination risks and contributes to quality assurance.
Focus on a wide range of laboratory applications
With its flexible temperature control and adjustable shaking motion, the device opens up a wide range of possibilities for sample preparation and incubation. Typical areas of application:
-
Cell culture and tissue samples: Uniform mixing and precise incubation temperatures for reproducible cell growth results, especially with sensitive cell lines.
-
Microbiology and fermentation: Reliable cultivation and propagation of bacteria, yeasts and moulds in a controlled moving water bath.
-
Enzymatic reactions: Ensuring optimal conditions for enzyme activity studies, for example with DNase, proteases or amylolytic enzymes, where constant temperature and movement increase the reaction yield.
-
Food and environmental analysis: Performing temperature-dependent analyses, such as shelf life studies or microbiological contamination measurements of food samples.
In addition, the SB-35 is ideal for sample preparation in pharmaceutical research, temperature control of buffer solutions or preheating of culture media.
FAQs on use and maintenance
How often should the bath water be changed?
It is standard practice to change the water once a week; more frequent replacement is advisable in cases of intensive use or risk of contamination.
How is calibration carried out?
For reliable measurement results, regular checking and calibration with an external precision thermometer is recommended - especially in accredited laboratories.
Which liquids can be used?
Distilled water is mainly used; alternatively, temperature-resistant, non-corrosive heat transfer fluids and buffer solutions are suitable.
Is maintenance complicated?
The stainless steel surfaces, corrosion-resistant housing and easily removable spring basket reduce maintenance and make cleaning much easier.
Are all safety-related guidelines met?
Yes, the system complies with safety class 2, is CE-certified and suitable for professional laboratory use.
Which sample vessels can be used?
Thanks to the flexibly adjustable spring basket, a wide variety of formats - from flasks and tubes to large cell culture bottles - can be accommodated without any problems.
What is the timer function useful for?
It enables automated shaking or incubation cycles with precise control of operating times, ideal for standardised workflows.
