Votre recherche pour: Barreaux magnétiques

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.

Magnetic stirring bars, PTFE, octagonal, assorted, Spinpak®, SP Bel-Art

Fournisseur: Bel-Art Products, a Part of SP

Description: Eight-sided Spinbar® octagonal magnetic stirring bars provide greater surface area and added turbulence when compared to smooth cylindrical bars.

Magnetic stirring bars, PTFE, star-shaped, Spinstar®, SP Bel-Art

Fournisseur: 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.

Magnetic stirring bars, cylindrical, PTFE, Spinbar®, SP Bel-Art

Fournisseur: 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.

Magnetic stirring bars, PTFE coated, cylindrical

Fournisseur: KARTELL

Description: PTFE coated, cylindrical.

Barreaux d'agitation magnétiques, PTFE, ovales

Fournisseur: Brand

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

Magnetic stirring bars, PTFE, elliptical, Spinbar®, SP Bel-Art

Fournisseur: 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.
