Benefits & Key Features of ILT Press-Fit SecureTM Screw Caps
Press-Fit Secure™ screw caps use a patent pending design that reinforces the seal at the point where evaporation starts. This creates stronger, better sealing for storage, transport, and analysis. The caps support evaporation control across chromatography use, from GCMS to LCMS.
Centered Seal System for Consistent Alignment
ILT’s Centered Seal System ensures the liner seats correctly every time. Proper alignment reduces the risk of leaks or mechanical stress during tightening.
Reinforced Liner That Locks in Place
The top facing liner in Press-Fit Secure™ caps fits securely into the top of the cap. This prevents push through, fallout, and misalignment. Users can confirm proper seating at a glance.
Leak Proof Seal Protects Specimen Integrity
A stable, leak proof seal reduces unwanted air exchange and minimizes evaporation loss to maintain sample consistency and support cleaner GCMS and LCMS results.
Low Bleed Silicone PTFE for Clean Results
The precision molded liner is made using platinum cured silicone and is conditioned to ILT’s Level-3 standard. The Press-Fit Secure™ cap offers low bleed performance suited for GCMS and LCMS, promoting clean baselines and sharp peaks.
Pre-Slit Liners Have Reduced Weight Loss
Available in pre-slit versions. Compared to a standard 9mm pre-slit silicone/PTFE lined cap, the Press-Fit Secure™ cap had a third of the percent weight loss over time.
Built for High Throughput Workflows
Press-Fit Secure™ screw caps are durable enough for fast handling and automated processes. The strengthened interface reduces rework caused by evaporation or compromised samples.
