Precision Laboratory Bottle Caps — Engineered for Every Need

We manufacture a comprehensive range of laboratory bottle caps crafted from high-performance materials like PBT, PP, and TPX — each designed to meet specific chemical resistance, thermal stability, and sealing requirements for diagnostic and pharmaceutical applications.

Standard Screw Cap PBT

Made from Polybutylene Terephthalate — typically black, offering high chemical resistance for demanding laboratory environments.

High-Temp Cap PBT

Red/Brown cap ideal for sterilization and high-heat applications — engineered to retain integrity under extreme thermal conditions.

PBT Cap with PTFE Seal PBT + PTFE

High chemical resistance cap in red, featuring a PTFE-coated inner seal for enhanced protection against reactive chemicals.

Premium Cap TPX

Made from Polymethylpentene — white/colorless, offering excellent chemical resistance and outstanding high thermal stability up to autoclave temperatures.

Membrane Cap PP / PTFE

Features a gas-permeable PTFE membrane for pressure equalization during autoclaving — essential for sealed containers in sterilization processes.

Standard Screw Cap PP

Polypropylene cap, typically blue — the go-to choice for general laboratory storage, offering reliable sealing at a competitive price point.

Vented / Port Cap PP

Includes built-in openings for tubing connections — ideal for liquid transfer, titration setups, and continuous flow applications in labs.
