Strong Alnico V Magnetic Egg Shape Stir Bar Feature:
Item No. MSB-PR series
Material Polytetrafluoroethylene (PTFE) , Teflon
Color White
Shape Egg, Oval-Style
Name: Magnetic Stirrer
Material: PTFE, strong magnet
Model: Plum blossom type
Egg-shaped stir bars have oval magnets-ideal for use in round-bottom flasks. Shape conforms to flask bottom and ensures complete mixing. Super-strong Alnico V magnets remain coupled to drive magnets-resisting spin out at high stirring speeds. One-piece coating of PTFE resists corrosion, heat, and cold. Chemically inert stir bars won. Low-friction PTFE coating ensures smooth spinning and maximum energy transfer.
These egg-shaped stirring bars are designed especially for use in round-bottom vessels as they spin unrestricted by the vessel contour. Particularly well suited for round bottom flasks; shape ensures complete mixing Offers minimal contact when used in plastic containers Egg shape

Strong Magnetic, New & Clean & Cute
High temperature: the use of operating temperature up to 250 ℃
Corrosion resistance: for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents
High lubrication: the lowest coefficient of friction in solid materials. X Shape Magnet Stir Bar Alnico
Low temperature resistance: good mechanical toughness, even if the temperature dropped to -196 ℃, can also maintain a 5% elongation
No adhesion: with the smallest surface tension in the solid material, no adhesion to any substance
Weather resistance: long-term exposure to the atmosphere, the surface and performance remain unchanged, there is B06B plastic in the best aging life
Non-toxic: with physiological inertia, as artificial blood vessels and organs long-term implanted in vivo no adverse reactions
Homemade Stir-plate vs. Laboratory Equipment
The top image shows a STIR40 Stir Bar Magnet with a B44Y0 magnet underneath. The lower image shows the same Stir Bar Magnet with a pair of B664 magnets underneath. We found more strength using configurations like the lower image. PTFE Coating Magnetic Stir Bar Gear Style
Should you make your own stir-plate or purchase one? That depends both on your budget and how you will use it. Lab quality stir-plates come with built in speed controls that usually work quite well. Lab stir-plates often incorporate a heating element, handy if you need to keep your solution warm. Gear Shape Spinbar Stirring Mixer Stirrer Bar Magnets
A homemade stir-plate made with recovered materials (like a fan from a PC) can be quite inexpensive. This project is popular among home brewers who prepare their own yeast for beer.
If you use a lab-quality stir-plate, be sure to check what type of magnet is used inside. A neodymium magnet is the strongest type of permanent magnet, and typically works best with these strong Stir Bars. A ceramic or Alnico magnet inside the stir-plate is much weaker than a neodymium magnet. While it will still work with the neodymium stir bars shown here, it is possible to demagnetize the ceramic or Alnico magnet inside the stir-plate. X-shaped PTFE Covered Magnet Stirring Bar
