11 mm Snap/Crimp Caps with Silicone/PTFE Septum

ms-Pure Silicone/PTFE Septum: non-pigmented Silicone Septum
With the increasing sensitivity of GC‘s and HPLC‘s there is an increased need for low bleed septum material to reduce the potential for sample error and to improve overall reliability. Pigmentation in coloured septum material can be a source of contaminant and tests show that the ms-Pure Septum is over 60 % cleaner than the standard white/red versions on the market.
