18mm Microcenter Liner Screw Caps

ILT’s customizable 18mm Microcenter Liner Screw Caps are made from steel, and are lined with combinations of white silicone/blue PTFE. Microcenter lined caps have a standard silicone thickness around the perimeter of the liner to maintain good fit, but with a thin 0.060in center liner to allow penetration from the SPME injection needle without damage to the fibers. Caps manufactured by ILT provide the high level of cleanliness needed to meet analytical laboratory requirements. Interested in our products? Contact us to be connected to our sales team.

Our high-quality caps are available in silver, with liner thicknesses of 1.5mm or 2.5mm. 

All of our products are tested in our onsite laboratory, fully equipped with state-of-the-art instrumentation to ensure quality control. As the largest global producer of lined caps, ILT is dedicated to maintaining the highest standards in the industries of manufacturing and material science.

We understand that every laboratory has unique needs and requirements. From product design to laboratory testing, our creativity is found nowhere else in the industry. We use FDA-approved materials in accordance with GMP and ISO 15378 standards.
