Until now, magnetic crimp caps made of steel or bimetal for injection vials with ND20 crimp rim were only available with hole sizes of 5 mm or 8 mm. However, sampling in the bypass of a control system with an ND20 sample port requires simultaneous insertion of two adjacent syringe needles, which requires a hole size of 10 mm. Die innovative Lösung von LABC-Labortechnik aus Hennef besteht darin, eine 20 mm Aluminium Bördelkappe mit zentralem 10 mm Loch mit einem magnetischen Ring zu versehen, der durch die eingelegte Dichtscheibe fixiert wird. As an added benefit, these magnetic aluminium caps allow for much easier and more effort-saving use compared to conventional steel caps with 8 mm hole.
