Digital Hotplates / Hotplate Stirrers
Look for this in your magnetic hotplate stirrer
Some things to think about before your purchase. What matters most to you and your colleagues?
Strong magnetic coupling
Unique permanent magnets can guarantee strong magnetic coupling, effectively preventing stir bar decoupling during the stirring process. Even when the bottom of the container is not touching the stirrer plate surface.
Precise speed control
When it comes to stirring, precision is key. The curated collection of magnetic hotplate stirrers below are all tested thoroughly for accuracy and precision.
Temperature accuracy
It’s easy enough for you to verify. We invest a lot of time into building or sourcing magnetic hotplate stirrers that are accurate.
Size and capacity
Can you improve an SOP by stirring larger volumes of sample? The curated magnetic hotplate stirrer collection below contains units up to 10X10.
Magnetic Hotplate Stirrers That Don’t Jump or Dance
Never splash samples onto your hands. Never return to stagnant samples.
Even the most basic heated stirring applications still need to be reliable.
Your old magnetic hotplate stirrers are caked with a decade of gunk. The magnetic coupling is weak, and your controls don’t respond the way you want.
And every once in a while, you return to check on your sample to find the stir bar dancing around like P.Diddy. .
So you don’t save yourself any time by walking away. Because you have to keep an eye on it.
Every magnetic hotplate stirrer in the curated collection below is sturdy, stable, easy to clean, and strong.
You’ll know you made a smart investment with your first sample next week.
Why does strong magnetic coupling on my magnetic hotplate stirrer matter?
If fluids are too viscous or the magnetic field is too weak, the stir bar doesn’t do its job. Instead, it wobbles around uselessly.
It doesn’t always happen right away. So you may think your sample is mixing, walk away to check on other work, and return to a sample in the same state you left it.
Waste of time!
Strong magnetic coupling allows your magnetic hotplate stirrer to overcome viscosity and avoid decoupling more than weak magnetic coupling.
Seems obvious. But older magnetic hotplate stirrers often have weakened magnets. And operators keep using them because the quality of the magnet has degraded so slowly that it’s imperceptible.
Here’s an example of what new, strong magnetic coupling can do (this example is from the Yamato MFH Versatile Magnetic Stirrer with Hot Plate).
A more powerful magnetic coupling enables a greater stirrable range, meaning you can mix more types of liquids across a greater variety of containers. It saves users time and energy with:
- Less vessel transference.
- Less cleanup.
In the case of the Yamato stirrer, it’s about 50% more range than other stirrers on the market.
