Description
The HI190M is a compact and lightweight magnetic stirrer. With a small footprint, lack of laboratory bench space is no longer a concern. Built to last with a protective covering and a user-adjustable stirring speed, this small magnetic stirrer is great for any lab space.
  • Compact size to maximize bench space for efficiency and safety.
  • Speedsafe™ mechanism ensures that the maximum speed is never exceeded.
  • Great for use in any sized laboratory.
Ideally, when performing electrochemistry measurements, the sample being tested should be stirred. The use of a stir plate allows for proper mixing and the sample to be homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time for a sensor to achieve a stable reading.
 
Compact & Cost-Effective
The HI190M-1 small magnetic stirrer is compact and lightweight, allowing for easy handling in the laboratory environment. Limited area on laboratory benchtops is no longer a concern with this durable, space-saving stirrer. Power-indicating LED lights also assure users at a distance that the stirrer is in operation. The durable plastic covering will resist harmful effects of accidentally spilled chemicals. The HI190M-1 magnetic stirrer is cost-effective for the customer that does not need the added expense of a heating element. The advanced design incorporates electronic controls that allow the user to easily regulate the speed with great precision.
 
Speedsafe™
Often in the lab, a sample is removed from a stirrer before the speed is adequately reduced. Normally this would cause the internal motor to accelerate until it is damaged. To control the speed from changes in viscosity or removing of the load the HI190M-1 magnetic stirrer incorporates the Speedsafe™ mechanism. With Speedsafe™, a speed sensing device (opto-sensor) is coupled with an FVC (frequency voltage converter) to monitor the stirring speed. As the speed reaches a preset maximum level, the speed limiter shuts down the VCO (voltage-controlled oscillator) to slow down the motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to such a high speed that will be hazardous to both the user and the stirrer; a feature not commonly found in conventional stirrers.
 
Fuse Protection
For safety, in the event of a short circuit, the HI190M-1 mini magnetic stirrer is equipped with a replaceable fuse. The circuitry of the HI190M-1 magnetic stirrer is grounded to the case for additional protection
  • Compact and lightweight magnetic stirrer with small lab footprint, adjustable stirring speed, power indicating LED lights indicate function from across the room, durable plastic covering to mitigate harmful effects of accidental spills.

How well does this perform with a 5l Flask?
David M F on Mar 23, 2019
BEST ANSWER: Hi David,
I used the stir plate with a much smaller vessel--100ml beaker, and it works well. I'd imagine it would work well with a bigger vessel if you had a large stir bar.

How much starter is needed for 10 gallons of wort?
Todd K on Feb 4, 2018
BEST ANSWER: For a 10 gallon batch of wort I like to use a 2 liter starter. This mostly makes sure that the yeast have enough food while doubling. I still start with extra yeast compared to a 5 gallon batch even when using a starter.

Very disappointing
Stopped working on maybe 3rd or 4th use. The power knob does not click on or off. LED light is on while plugged in but motor does not engage.

I've only used this once so far. Worked great. Easy to use. Quiet enough to sit in the kitchen without noticing it much.

Great for starters
I have only used it once but it worked great even with my giant 5,000ml flask. This was my first time doing a starter this way. I have to say it's way easier than coming by and stirring every once in a while. seems to be a very solid unit so we'll see if it's still running in a few years.

Good quality
The other generic stir plate that MoreBeer sells broke after a couple years of fairly infrequent use. Decided I’d pay a little more, and this is of much better quality and has more power than the other stirrer. I like the small footprint and it’s much quieter. Stirring a 2L flask with a vortex is completely silent. Great so far.
