Screw Cap

A secure, well-fitted closure is one of the most fundamental requirements in any laboratory, chemical handling, or industrial packaging workflow. The wrong cap can mean leaks, contamination, or compromised sample integrity. Our Screw Cap line offers an extensive range of bottle closure options from Rixius, covering a wide variety of thread sizes, materials, inlay types, and colours to suit virtually every container and application requirement.
