PolyMag® Screw Caps

• 9mm Magnetic Screw Cap
• Easy-to-use polypropylene screw thread format
• No crimping required
• Secure grip to autosampler magnets
• Liners manufactured from low extractable silicone

This PolyMagnetic cap combines the tried and true functionality of a standard 9mm polypropylene screw cap with a built-in steel overlay design. This cap eliminates the need for hard to crimp steel caps yet still allows for transport with a magnetic sample transport system. The unique design of the cap does not alter the compatibility of glass or plastic 9mm thread vials providing an excellent seal between the cap and vial.
