Metric Spinbar® Magnetic Stirring Bar Size and Selection Guide

Stirring Spinbar® Magnetic Stirring Bar Guide Magnetic stirring is used in a number of common laboratory procedures, yet the importance of selecting the best stirring bar for each particular application is often overlooked. The size of the magnetic stirrer, vessel shape (including the opening of the vessel that the stirbar has to fit through), viscosity and abrasiveness of the materials should all be considered when choosing the size, shape and materials (coating and magnet) of the magnetic stirring bar in order to achieve effective, efficient stirring results. First, let’s discuss magnetism....

Stirring Octagon Spinbar Magnetic Stirring Bars Vigorous, Thorough Mixing Used in conjunction with a magnetic stirring plate, Spinbar® stir bars enable uniform, consistent, and thorough mixing of chemical solutions. • ulti-faceted shape provides greater surface area and added turbulence M for more vigorous, thorough mixing when compared to the smooth surface of cylindrical bars • ivot ring allows the Spin Bar to “rock” while spinning for better mixing conditions P • lnico magnet encapsulated in FDA Grade, USP Class VI PTFE coating; A Superior chemical compatibility • Autoclavable • anufactured...

Stirring Color Octagon Spinbar Magnetic Stirring Bars Choose from Red, Yellow, or Blue Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Choose from red, yellow or blue. • lnico magnet encapsulated in FDA Grade, USP Class VI PTFE Coating – A Superior Chemical Compatibility • Interrupted profile provides greater surface area and added turbulence when compared to the smooth surface of cylindrical bars • Pivot ring allows the Spin Bar to “rock” while spinning for better mixing conditions (F37107-1303, F37108-1303, and F37109-1303 do not have a pivot ring)...

Stirring Polygon Spinbar Magnetic Stirring Bars without Pivot Ring Scrapes Solids from Vessel Bottom High quality PTFE encapsulated magnetic stirring bars ensure efficient mixing with consistent results. • ulti-faceted polygon shape with increased surface area creates M added turbulence relative to similar sized, smooth cylindrical bars to provide thorough mixing • bsence of a pivot ring allow the Spinbar to stay close A to the bottom of the vessel enabling “scraping” of solids • ptimal coupling with magnetic spindrive as entire O length of stir bar is in close contact • lnico magnet encapsulated...

Stirring Elliptical (Egg-Shaped) Spinbar Magnetic Stirring Bars “Eggcellent” for Round Bottom Flasks Used in conjunction with a magnetic stirring plate, Spinbar® stir bars create uniform, consistent, and thorough mixing of chemical solutions. • ontoured egg shape is ideal for use in round-bottom vessels/flasks; C ensures complete mixing • ffers minimal contact when used in plastic containers; minimizes scraping O • gg shape provides pivot point without a separate ring or E abrupt change in contour for smoother mixing • lnico magnet encapsulated in FDA Grade, USP Class VI PTFE Coating; A Superior...

Stirring Micro Spinbar Magnetic Stirring Bars Small Sample Mixing Designed for small volume mixing in vessels such as vials, tubes and gradient makers. • articularly useful for environmental testing and life science applications in which P small sample volumes need to be prepared and evaluated • lnico magnet encapsulated in FDA Grade, USP Class VI PTFE Coating; A Superior chemical compatibility • anufactured in a registered ISO 9001:2015 facility, as verified M by SGS certification • Autoclave safe Enlarged to Show Detail Actual Size when Document Printed at 100% 1 Enlarged to Show Detail 9 YELLOW...
