Elliptical Magnetic Stirring Bars Use Neodymium Magnet 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
We are Manufacturer Exporters and Suppliers of Plastic Egg Shape Magnetic Stirring Bars at wholesale competitive prices from China.
These stir bars are magnetic, and coated in PTFE, no harm to human body, and heat resistant to 250 celsius degree
The PTFE coatings are intended to be chemically inert, not contaminating or reacting with the reaction mixture they are in
Elliptical (egg shaped) magnetic stirring bars are particularly well suitedfor round bottom flasks. Their shape mimics that of a flask and ensurescomplete mixing. They also offer minimal contact when used in PVC containers. Egg Shaped Magnet Stir Bars Polytetrafluoroethylene
Magnetic stirrers can only be used for relatively small experiments of 4 liters or less.The mixing process is quieter and more efficient, and the stirrer is not EXCLsed to the external transmission component so it is not easily damaged
Stir bars help to build a relatively economical, environmentally friendly, and safe device that can greatly save manpower and reduce the use rate of flames, and relatively improve the safety of laboratories and home brewing
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
