Hanna Instruments HI200M-2 magnetic stirrer, stainless steel cover plate, 230 V
The Hanna Instruments HI200M-2 magnetic stirrer, stainless steel cover plate, 230 V is specially designed for precise and reliable stirring applications in the laboratory. Thanks to its stainless steel cover, it withstands exothermic reactions and enables efficient mixing of the sample. Its compact design makes it easy to use even in confined spaces, which sets it apart from many alternatives. Compared to similarly robust stirrers such as the [Heidolph Hei-PLATE Magnetic Stirrer], there are hardly any compromises in practice, making this device an extremely economical and robust solution for everyday laboratory use.
Compact design and powerful features
This mini magnetic stirrer was specifically developed to mix a maximum of 1 liter of liquid homogeneously and at the same time create permanently reproducible conditions. Researchers and laboratory staff benefit from the following features and advantages:
- Adjustable stirring speed with a range of 100 to 1000 revolutions per minute
- AISI 316 stainless steel cover plate for high chemical resistance
- Mini format (120 x 120 x 45 mm), ideal for small laboratory benches
- Weight of only 710 g for easy transportation
- 230 V power supply, suitable for the majority of common laboratory equipment
- Speedsafe mechanism that protects the motor from overspeeding
- Replaceable fuse in the event of a short circuit to ensure a high level of safety
Aside from these core functions, the durable construction and prudent design of the housing are also crucial. Instead of a plastic surface, the model relies on a robust stainless steel plate that is particularly resistant to harsh chemicals. This is an advantage when exothermic or highly corrosive reactions take place during the experiments, which could quickly damage conventional device surfaces.
Certifications and standards
The stirrer complies with the usual safety standards for laboratory equipment and impresses with its reliable electrical design and grounding of the housing. Users also benefit from a stable design that can be used safely and in compliance with the law in professional environments, for example under laboratory guidelines such as DIN and CE.
Application examples
- Biotechnological applications: Constant stirring keeps cell cultures or bacterial cultures in a homogeneous growth environment.
- Pharmaceutical and chemical laboratories: Exothermic reactions with aggressive chemicals require resistance to corrosion as well as safe handling.
- Food analysis: Uniform mixing of samples, for example in pH or conductivity measurements, enables reliable results.
- Environmental analysis: The preparation and stable homogenization of samples (e.g. water samples with dissolved substances) is greatly simplified.
The Speedsafe mechanism has proven itself in all of these areas, as it protects the motor from overloading and keeps the speed within a safe range, even when a vessel is suddenly removed.
FAQs
How exactly does the Speedsafe mechanism work?
Speedsafe monitors the engine speed using an opto-sensor linked to a frequency-to-voltage converter. If the speed suddenly increases (e.g. when removing the sample), it is regulated immediately to prevent damage to the device.
Can a stirring bowl format other than 1 liter be used?
The appliance is designed for stirring up to 1 liter of liquid. Although a larger volume can be placed, the stirring performance will decrease and the motor could be overloaded.
Which substances can be stirred particularly well?
Thanks to the stainless steel surface and the wide speed range, most laboratory liquids, including slightly corrosive solutions, can be stirred. Typical applications include aqueous samples, buffer substances, culture media or light acids and bases.
Is there a risk of overheating?
Heat can be dissipated relatively well through the metal surface. However, with exothermic reactions and prolonged operation, it must be ensured that the heat development remains within acceptable limits.
How does cleaning work?
The stainless steel surface is comparatively smooth and resistant to chemicals, so it can be easily cleaned with standard laboratory detergents, 70% ethanol or isopropanol.
Conclusion
The HI200M-2 magnetic stirrer offers a combination of compactness, safety and durability that is essential in many laboratory environments. It significantly simplifies the homogenization of samples and impresses with its Speedsafe mechanism, which protects both the motor and the user. Especially in the field of exothermic reactions and corrosive media, its stainless steel cover plate is a key feature for reliable results and a long service life in the laboratory.
