Laboratory Stir Bars
Flexible Magnetic Stir Bar Retriever, 40 cm Length, Spin Bar Removal
• Flexible magnetic stir bar retriever for removing spin bars from beakers, flasks and sample containers
• 40 cm length provides reach into deeper vessels, reduces the need to pour liquids to recover bars
• Magnetic tip captures PTFE coated stir bars through glass walls and narrow neck openings in typical labware
• Flexible shaft bends to follow vessel shape, helpful for round bottom flasks and curved container profiles
• For laboratory or educational settings only, use under supervision and rinse between samples to avoid cross contamination

PTFE Cross Stir Bar 38 x 38 mm, Stable General Purpose Stirring
• PTFE cross stir bar for magnetic stirring, 38 x 38 mm size, general purpose laboratory mixing applications
• Cross profile designed for extra stability on vessel bases, helps reduce jumping and loss of coupling
• Suitable for routine stirring tasks where standard cylindrical bars may chatter at higher speeds or in turbulence
• PTFE construction supports chemical resistance and simple cleaning between different solutions or reagents
• Use in laboratory or educational settings only, match stirrer size to vessel diameter and stirrer motor strength for best control
$11.00 (Ex GST)
PTFE Octahedral Stir Bar 5.5 x 42 mm, Turbulence at Low Speed
• PTFE octahedral magnetic stir bar, size 5.5 x 42 mm, designed for general laboratory stirring
• Profile described as similar to pivot ring type, but promotes more turbulence at low stirring speed
• Useful where mixing is needed at lower RPM, supports agitation without requiring high speed operation
• PTFE construction supports chemical resistance and easy cleaning between different solutions or reagents
• For laboratory or educational settings only, use under supervision and match bar length to vessel size and stirrer strength
