Reliable laboratory caps

LabCaps from KISICO are closures designed specially to withstand stress, such as those frequently encountered in analytics and in laboratories due to extreme temperatures, aggressive chemicals, or pressure.
Closures adapted to the product and the neck of the bottle offer a higher level of protection of the contents and the environment while preventing accidents such as leaks, from occurring. LabCaps provide greater safety during filling, transport, storage, and use. Careful planning and development are therefore essential, as any potential weak point must be considered and eliminated at the design stage. This allows KISICO to offer high-performance, high-quality, and cost-effective products.
By selecting the appropriate raw materials, LabCaps can also be used for high-temperature applications over 300°C. They can be produced in the cleanroom. Special sealing liners ensure optimum tightness even with critical filling materials, such as hazardous goods.
Closures with a center opening that can be used, for example, as coupling connections and pipette closures.


Temperature- and chemical-resistant caps as well as screw-thread couplings for a variety of laboratory applications.
