ONiLAB Lab Analog Overhead Stirrer, 10L Capacity, 100-2500rpm Adjustable Speed,Max.Viscosity 10000mpas, Lab Mixer with Overload Protection, Overhead Mixer with Support Stand&Two Stirring Rods,110-220V

This is a lovely piece of simple kit that gets the job done. Quiet, efficient, good torque. No wobblies or weird vibrations. In short this thing works great for us. I also want to praise the team there - mine arrived w/ a defective transformer and they replaced it without fuss. Very satisfying customer support people, and prompt. THIS MATTERS!

Good! The only complaint is when you first turn on the mixing, it will at first mix with a joult of power for 2 seconds and then equilibrate to the selected speed. When purchasing attachments note the distance between the hot plate and overhead stirrer.

I receieved the item with two of the upper support rods instead of one upper and one lower so they do not screw together and I cant use the stirrer.

I like this overhead stirrer. It makes my cosmetic formulation less laborious. I typically use either 500 or 1000ml beakers with it. The stand is sturdy enough to hold this stirrer, but the clamps aren't the strongest. I have no problem with the stirrer moving up or down, but I do have issues with it moving left to right while mixing, which is exacerbated a bit by there being nothing to hold the beaker in place at the bottom. The speed knob jumps a bit in speed increments - for example, the first little bit after turning it on has barely any spinning, then very quickly jumps up to a much faster rpm. The speed up and speed down is not as smoothly incremental as a twist knob would imply. That said, at this price I've found it to be a great addition to my lab. It works very well with a few quirks, but none of its quirks are deal breakers for me. I'd buy it again.

el comportamiento hasta ahora ha sido bueno, esperemos el transcurso del año
