Stirrers & Stir Bars

Octagonal, Teflon-coated, leak-proof magnetic stir bar.

Three-pack contains one each of 1”, 1.5” and 2”.  Octagonal, Teflon-coated, leak-proof magnetic stir bar.

- Color-coded bars with pivot rings

This new stir plate will fit up to a 5000ml flask and also feature a pH probe holder that winemakers like. Has an on/off switch as well as a speed control dial, and a screw-in fuse in the back. Standard 110V power. Includes 1" stir bar.

This compact stir plate features an on/off switch as well as a speed control dial, and a screw-in fuse in the back. Comes with magnetic stirbar. 

Useful for growing up yeast cultures. A constantly stirred yeast starter will yield a much higher cell count than a non-stirred starter 

Circulus™ Magnetic Stirring Bars offer fast mixing action and strong turbulence as well as greater stability with less drifting at higher speeds. Excellent self-centering characteristics.

Mini Magnetic Stirrer
An economical solution made for ultimate function

The Mini Magnetic Stirrer by Heathrow Scientific is an economical solution made for ultimate function with optimal magnetic coupling to ensure dependable stirring efficiency.

A powerful magnetic coupling of the high-quality stir bar and the unit ensures consistent accurate alignment which significantly reduces spin-outs during acceleration or deceleration of spin speeds and ensure maximum stirring performance, every time.

The mini stirrer is made from an ABS and PC blend that is chemical resistant making the unit easy to clean.

The low-profile design is lightweight for transporting with ease and the small footprint saves valuable space on a bench top.

The mini stirrer offers quiet operation with low vibration which helps users stay focused by reducing noise in the lab.

Ideal for routine stirring applications in general research, life science, industrial, quality analysis, and clinical lab settings.

2 High quality stir bars (35x9mm) are included to ensure maximum stirring performance. HS Item #120552.
