As a replacement for the discontinued 11 mm crimp closures with MN REF 702001, MACHEREY-NAGEL has added a range of new natural rubber/ETFE closures in silver (MN REF 70246), green (70246.1), red (70246.2) and blue (70246.3) caps to their delivery program.
The high restoring forces of the natural rubber allow multiple injections without sample loss. In comparison to the discontinued NR/ETFE closure 702001, 70246 has a lower durometer (45° shore A instead of 60° shore A) and thus is easier to penetrate. This offers more safety for the needle and less fragmentation during piercing (lower risk of contamination).
The ETFE lamination has a comparable chemical resistance to other types of PTFE.
The main area of usage for these closures is in GC applications where instrument manufacturers like Agilent offer them as a cost-effective closure for routine analysis (see 5181-1210/100; 5183-4498/1000).
The self-manufactured closure is available ex stock at sensational pricing. For those who prefer screwing instead of crimping, a screw closure N 9 with a blue open top cap and with natural rubber/ETFE liner can be obtained with MN REF 702460.
