Hanna Instrument Magnetic Mini-Stirrer (230V) – HI190M
A portable and lightweight magnetic stirrer is the HI190M-1. The housing and lid of this mini-stirrer are made of durable ABS plastic and are resistant to many dangerous substances. The stirring speed can be changed between 100 and 1000 RPM. When lab benchtop space is at a premium, the HI190M stirrer’s small footprint is beneficial.
- SpeedsafeTM technology
- The light that indicates the power
- programmable speed regulator
The test sample should ideally be mixed before electrochemistry measurements are conducted. A magnetic stirrer is used to ensure correct mixing and uniform temperature and consistency of the sample. A sensor’s response time to obtain a stable reading is sped up by agitating the sample.
- Compact and economical
Due to its small size and lightweight, the HI190M-1 mini-magnetic stirrer is simple to use in a laboratory setting. With the help of this sturdy, space-saving stirrer, a lack of space on laboratory benchtops is no longer an issue. Users at a distance are further assured that the stirrer is in use by power-indicating LED lights. Chemicals that are spilled accidentally won’t destroy the sturdy plastic coating. For customers who do not require the additional costs of a heating element, the HI190M-1 magnetic mini-stirrer is a cost-effective option. The cutting-edge design includes electronic controls that let the user easily and precisely manage the speed.
- Speedsafe™
In the laboratory, a sample is frequently taken out of a stirrer before the speed has been sufficiently decreased. Normally, the internal motor would speed up until it was harmed. The SpeedsafeTM mechanism is incorporated into the HI190M-1 magnetic mini-stirrer to adjust speed in response to variations in viscosity or the removal of a load. With SpeedsafeTM, the stirring speed is tracked by an Opto-sensor, which is connected to an FVC (frequency voltage converter). The voltage-controlled oscillator (VCO) is turned off by the speed limiter when the speed reaches a certain maximum level, which reduces the motor speed. This prevents the motor from rapidly accelerating to a high speed that would be dangerous to both the operator and the stirrer when the load is quickly withdrawn from the stirrer, a characteristic not frequently present in conventional stirrers.
- Switch Protection
The HI190M-1 has a changeable fuse for added security in the case of a short circuit. For added protection, the HI190M-1’s circuitry is grounded to the casing.
