Qunclay 6 Pcs X Shape Magnetic Stir Bar, 20mm (0.78 Inch) PTFE Cross Shape Stirring Bars, Lab Mixer Stirrer for Industrial Laboratory, Magnet and Balanced for Magnetic Stirrers

Features: Maintenance simplicity: The non-porous ptfe surface releases quickly clean during washing. Bars can be rinsed with deionized water or appropriate solvents between experiments without absorbing chemicals, contribute proper lab hygiene practices. Application range: Suitable for laboratory environments including educational institutions, research facilities, and quality control stations. Also functions in non-traditional settings such as home brewing operations and hobbyist mixing applications. The compact size stores conveniently in drawer organizers or lab supply cabinets. Specifications: Material: ptfe Color: white Size: about 0.79 inch/ 20 mm Package includes: 6 × magnetic stir bar cross Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays

• Size Specifications: each stir bar measures 20mm (0.78 inch) 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
