Millions of caps of all different shapes and sizes are produced annually at Lüdi Swiss.

The fastener assortment LABOCAP for example, is produced for test tubes and Erlenmeyer flasks made from aluminum and stainless steel and are particularly used in microbiology. These caps are reusable, heat resistant, washable, rust-proof and distinguish themselves through their stable design and long lifespan. They guarantee that test tubes in the bacteriological laboratory are kept longer sterile but are not hermetically closed.

Customized precise caps and screw caps are used worldwide particularly in chromatography and human medicine.
