Product Details
✓Size Specifications: each stir bar measures 0.39 x 1.38 inches/ 10 x 35 mm in length with an 8mm (5/16 inch) diameter; This compact cross shape fits standard laboratory glassware, beakers, and flasks; The 6-piece set provides adequate replacement options for ongoing experiments and daily mixing tasks in research settings
✓Material Composition: constructed from virgin PTFE, these x shape stirring bars resist powerful durability; The non-stick surface prevents sample adhesion between uses; PTFE material withstands wide temperature fluctuations without degrading, ensuring consistent performance in variable laboratory conditions
✓Shape Performance: the cross-shaped geometry creates turbulent stream patterns that enhance solution blending compared to cylindrical alternatives; This configuration suspends particulates effectively and maintains uniform temperature distribution throughout liquids; The design proves particularly effective for viscous solutions requiring sustained mixing action
✓Versatile Usage: these mixer bars function with standard magnetic stirrer plates found in clinical, educational, and industrial laboratories; Applications include dissolving reagents, suspending cells, preparing buffers, and mixing chemical syntheses; The bars accommodate various container shapes including round-bottom flasks and flat-bottom beakers
✓Operational Stability: the balanced construction allows continuous whirl without wobbling or jumping during prolonged mixing sessions; Each bar maintains consistent contact with stirrer plates, reducing decoupling incidents; This stability supports the whole night reactions and long-duration protocols where uninterrupted stirring is required
