A mixed experience with 70mm PTFE Magnetic Stir Bar

I purchased the 70mm/2.75 inch PTFE Magnetic Stir Bar with a smooth ridge for my laboratory experiments. The product arrived promptly and was in good condition. The first thing I noticed was its smooth surface and the solid build. The magnetic strength of the bar is impressive and it handles larger volumes of solutions with ease. It creates adequate turbulence suitable for homogenizing the mixture. The smooth ridge around the shaft provides resistance to slipping off the stirrer, preventing…

Pros
  • Thanks to its smooth ridge design, the 70Mm / 2.75 Inch PTFE Magnetic Stir Bar allows for efficient mixing of liquids in laboratory and industrial settings.
Cons
  • Not suitable for high heat environments

70Mm / 2.75 Inch PTFE Magnetic Stir Bar With Smooth Ridge - High Quality!

As a scientist, having quality equipment is essential. This stir bar certainly met my expectations! The smooth ridge made for a seamless mixing experience and the magnetic pull was strong enough to handle even thicker solutions. The 70mm size was also perfect for my needs. My only criticism is that the stir bar was slightly more expensive than others on the market, but it was worth the investment for the high quality. Overall, I highly recommend this product.

Pros
  • With its strong magnetic properties, this stir bar can be easily attached to a magnetic stirrer, providing a simple and effective way to mix liquids without the need for manual effort
Cons
  • At only 70mm / 2.75 inches in size, this magnetic stir bar may not be large enough for some experiments or laboratory procedures, decreasing its overall usefulness
