Weewooday 130 Pieces PTFE Magnetic Mixer Stirrer Bar, White Color Stainless Steel Laboratory PTFE Stir Plate Bar, Mixing Plate Magnet Stick (30 mm/ 1.18 Inch)

Work as intended and have been through my pressure canner a couple times without any issue.

Mixing dye with these is better than with a blender. Mixes powders in well. High quality and heavy and doesn’t scratch the glass

Excellent product; great value for money cost.Great performance during my lab testing.

Magnetic, encapsulation still intact after many hours. Not much else to say other than I'd probably buy again if I need more.

Works Great and arrived on time.

Do what they're suppose to do. Seem good quality, they do stick to metal lids but by using another magnet you can pull them off

The magnetic stir machines only come with 1 stir bar and you are going to need many for your multiple LC (Liquid Culture) jars. I had 11 of these and somehow I’ve already misplaced 2 of them! They’re out the garden somewhere that I have dumped some questionable LC & eventually I’ll get out the metal detector and find them again. 😉🤣

Work great, especially if you put them in your jar BEFORE sterilization. I'm not saying I didn't, but make sure you do :)

El tamaño es adecuado para agitar, sin ser demasiado grandes o pequeños. Son totalmente lisos

The product is used in our main lab
