You Searched For: Magnetic Stirring Bars

Magnetic stirring bars provide effective stirring of samples via magnetic manipulation. Many models feature an octagonal shape with a central integrated pivot ring for optimal turbulence while stirring thanks to a greater surface area. The heavy-duty magnetic strips is one of the frequently used tools, strong enough to hold the solution. Commonly coated in Teflon to provide chemical inertness, occasionally glass will be the coating for use with most liquid alkali metals and alkali metal solutions in ammonia. Both of these coatings are inert and will not contaminate or react with the reaction solution.

Supplier: Bel-Art Products, a Part of SP
Description: These PTFE covered egg-shaped magnetic stirring bars have their own pivot point without a separate ring or abrupt change in contour. Designed especially for use in round-bottom vessels, they spin unrestricted by the contours of the vessel.

Supplier: Brand
Description: These oval shaped PTFE magnetic stirrer bars are ideal for vessels with round bottom such as round bottom flasks.

Supplier: Brand
Description: PTFE-coated cylindrical magnetic stirring bars.

Supplier: Bel-Art Products, a Part of SP
Description: Stirring bars ensure centering and smooth running characteristics via a small removable pivot ring in the center. The pivot ring minimises the contact area of the bar to the vessel, reduces friction and lessens marring of plastic containers.

Supplier: KARTELL
Description: Economical stirring bars designed for a wide variety of applications.

Supplier: Bohlender
Description: Magnetic stirrer bars with magnetic core of samarium-cobalt encapsulated in PTFE. Torque loads transmitted with these stirring bars are four times larger than conventional magnetic stirring bars.

Supplier: Bohlender
Description: Double end shaped PTFE magnetic stirrer bars with magnetic core of Alnico 5 encapsulated in PTFE. Stable discs present at both sides provide an excellent stirring capability.

Supplier: Bel-Art Products, a Part of SP
Description: Spinstar® star-shaped stirring bars creates a deep vortex at relatively slow speeds. Bars are an exact fit for the inside diameter of the beaker indicated.

Catalog Number: (BELAF371500000)
Supplier: Bel-Art Products, a Part of SP
Description: This magnetic stirring bar, with Alnico magnet encapsulated in PTFE coating, fits into the standard 10 mm light path cuvette and provides rapid vertical and horizontal mixing with a minimum of vortexing when placed on a magnetic stirring machine.
