18mm Closures

Vials with septa-capped 18mm caps are used as sample vials, and these vials can also be used as storage bottles. Precision-machined threads always ensure sealing. It fits perfectly with the matching 18mm magnetic metal screw cap and PTFE/silicone septum. The caliber of this series of headspace bottles is 18mm, and the size of 20ml is 22.5*75.5mm.

The head space of the threaded mouth is easy to use, without tools, the Cap can be screwed directly on the bottle mouth; the risk of wrong clamping jaws is avoided, and the repeatability of the analysis results is guaranteed; the professional precision makes the gasket and the bottle mouth more sealed; Septa’s The thickness is less than the thickness of the jaw cover, making the puncture easier and safer; the sample can be taken out in the field without taking it out in the laboratory.

The 18mm Magnetic Metal Closures produced by Aijiren are made of magnetic metal. This metal has its own magnetism and can be adsorbed on the robotic arm of the autosampler, which facilitates the accuracy and stability of sample injection. The height of the 18mm Magnetic Metal Closures is very high, which provides a large space for the thread, the multilayer thread ensures sealing, the metal texture meets the precise thread, and the 8mm center hole meets the sample injection.

Also because the 18mm screw headspace vial needs to be used on the autosampler, the 18mm screw magnetic closures have a center hole for easy sampling. Septa uses a composite method of PTFE and Silicone. The composite process is Aijiren¡¯s exclusive patent and does not use any adhesives. Compound, compared to septa using adhesive, the texture is softer and has less influence on the experiment. The 18mm screw magnetic closures produced by Aijiren are the most suitable partner for gas chromatography.

Aijiren usually packs 100 caps in a packaging bag, starting with a pack. Aijiren will choose the delivery method according to the quantity of products ordered by the customer. If the quantity ordered is small, it can be sent by express, and if the quantity is large, it needs to be transported by sea. If the customer is in a hurry, it can also be shipped by air.
