ND20 aluminum flare caps Butyl shaped washer
The molded butyl discs are cleaner and denser compared to a conventional punched disc. In comparison, pure butyl is an inexpensive septum. Due to the lack of PTFE lamination, the closure is only suitable for non-critical analyses.
The closure can be used in the temperature range from -40 °C to 120 °C. The hardness is 55° shore A.

The ND20 closures with an inserted butyl molded washer are available with various crimp caps. In addition to the non-magnetic standard cap ND20, crimp caps are also available for special applications. Medium and full tear-off caps have a tab so that the cap can be removed from the vial without tools. Headspace flare caps have a perforation that opens automatically in the event of dangerous overpressure. Magnetic crimp caps with 6mm and 8mm holes complete the range.
