Product Description of Magnetic stir bar, 6×35 mm

The Magnetic Stir Bar, 6×35 mm is a precision-designed laboratory accessory essential for efficient mixing and agitation of liquid samples. Designed for compatibility with a wide range of magnetic stirrers and hotplate stirrers, this stir bar is manufactured with high-quality, chemically resistant materials, ensuring durability, reliability, and consistent performance across diverse laboratory environments. Its 6 mm diameter and 35 mm length make it particularly suitable for medium-volume sample containers such as beakers, Erlenmeyer flasks, and other glassware used in chemical, biological, and analytical laboratories.

Magnetic stir bars work on the principle of magnetic coupling between the stirrer’s rotating magnetic field and the embedded magnet inside the stir bar. This non-intrusive stirring mechanism eliminates the need for mechanical stirring rods, reducing contamination risks and improving efficiency.

Technical Features

  • Dimensions: 6 mm diameter × 35 mm length.

  • Material: High-grade PTFE (Polytetrafluoroethylene) coating for chemical inertness.

  • Magnetic Core: High-strength Alnico V or rare earth magnet ensuring efficient coupling with stirring units.

  • Shape: Cylindrical with slightly rounded ends, minimizing friction and enabling smooth rotation.

  • Surface: Non-stick PTFE surface prevents sample adhesion and is easy to clean.

  • Temperature Resistance: Can withstand a wide range of temperatures (-200 °C to +250 °C) suitable for hotplate stirring applications.

  • Sterilization: Autoclavable, allowing reuse in sterile environments.

Key Benefits

  1. Efficient Mixing: Provides uniform mixing of liquids, ensuring homogenous sample preparation for analytical or experimental accuracy.

  2. Compact and Versatile: With a 6×35 mm size, it is versatile enough for medium-volume mixing without occupying excessive vessel space.

  3. Chemical Resistance: PTFE coating ensures compatibility with acids, bases, solvents, and most laboratory reagents.

  4. Durability: The combination of a strong magnetic core and protective PTFE jacket extends product life, even with repeated sterilization cycles.

  5. Ease of Cleaning: Non-stick surface simplifies cleaning, preventing sample carryover and contamination.

  6. Safe and Reliable: Non-mechanical stirring minimizes contamination risks and ensures safe operation within sealed or closed vessels.

Applications

The Magnetic Stir Bar, 6×35 mm is widely used across various laboratory and industrial settings:

  • Chemical Laboratories: For preparing solutions, dilutions, and chemical reactions requiring continuous stirring.

  • Biological Research: Ensures consistent mixing of buffers, culture media, and biological samples.

  • Analytical Labs: Used in titration, spectrophotometry, and chromatography sample preparation.

  • Pharmaceutical Industry: Assists in formulation studies, dissolution testing, and drug development processes.

  • Food & Beverage Industry: For sample homogenization in quality control laboratories.

  • Educational Institutions: Common tool in teaching laboratories for chemistry and biology experiments.
