Exceptional Durability and Chemical ResistanceCoated with premium PTFE, the stirrer bar resists damage from harsh acids, bases, and solvents, ensuring reliability in demanding laboratory environments. Its inert surface prevents reactions with sensitive solutions, maintaining sample integrity during all mixing procedures.
Precision Mixing With Pivot Ring DesignThe integrated pivot ring greatly reduces friction as the bar rotates, delivering consistent mixing at speeds up to 2000 rpm. This allows for smooth agitation even in high-speed operations, making the bar suitable for a wide range of vessel shapes and laboratory protocols.
Versatile and Easy MaintenanceAutoclavable and non-toxic, the magnetic stirrer bar can be sterilized and reused multiple times. Its non-stick, smooth surface allows for hassle-free cleaning, making it particularly convenient for busy labs. Available in multiple sizes, it accommodates vessels of varying volumes and geometries.
FAQ's of Magnetic Stirrer Bar With Pivot Ring, PTFE / ALNICO V MAGNET:
Q: How is the Magnetic Stirrer Bar with Pivot Ring used in laboratory applications?
A: The stirrer bar is placed into a liquid-filled vessel and used in conjunction with a magnetic stirrer machine. The rotating magnetic field causes the bar to spin, mixing the solution efficiently. It's suitable for general mixing, solution preparation, titration, and cell culture media agitation.
Q: What materials are used in the construction of this stirrer bar?
A: The bar comprises a high-strength ALNICO V magnet core, fully coated with PTFE (Teflon). This design provides both magnetic performance and excellent chemical resistance, making it safe for various laboratory chemicals.
Q: When should I choose a stirrer bar with a pivot ring instead of a standard stirrer?
A: A stirrer bar with a pivot ring is ideal when you need reduced friction and more stable, quieter stirring, especially at higher speeds or in vessels with irregular bottoms. The pivot ring's design ensures consistent maneuverability.
Q: Where can these stirrer bars be used?
A: These magnetic stirrer bars are suitable for laboratories in educational, industrial, and research settings. They are compatible with a wide range of beakers, flasks, and other vessels, accommodating various experiment volumes.
Q: How do I clean and sterilize the stirrer bar for repeated use?
A: The PTFE-coated surface allows for easy cleaning by rinsing with water or mild detergents. For sterilization, the bar can be autoclaved at temperatures up to 260C, making it safe for reuse in sensitive applications.
Q: What benefits does the PTFE coating provide?
A: PTFE coating offers high chemical resistance to acids, bases, and most solvents, ensuring longevity and sample purity. It is also non-stick, which prevents build-up and simplifies post-use cleaning.
Q: Is this magnetic stirrer bar suitable for all magnetic stirrer machines?
A: Yes, the bar can be used with most magnetic stirrer machines, provided the size of the stir bar matches the vessel and the magnetic field capacity of the stirrer. It supports speeds typically up to 2000 rpm.
