competitive price thanks to smaller septum diameter
Headspace chromatography requires the vial to be tightly sealed and the closure to withstand pressure. This requires some effort and is tiring when closing larger series. Our screw- top headspace vial only requires a torque < 1 Nm for a pressure tight seal while common solutions require a torque > 8 Nm.
Our screw caps not only close smoothly, they also have a smaller diameter than aluminium crimp caps for Headspace. Because of the smaller diameter the septum, which is the cost defining factor, is therefore less expensive.
