Thermo Scientific Crimp Caps

Crimp Caps for Autosampler Vials from Thermo Scientific

Minimize contamination from handling with convenient, pre-assembled Thermo Scientific 8 mm and 11 mm vial crimp caps, compatible with most HPLC and GC autosamplers.

Choose from Thermo Scientific National or Thermo Scientific Chromacol brands.

Thermo Scientific crimp caps are available in three different performance levels to suit different experiments, analytes, and budgets. SureSTART 11 mm crimp caps provide you with the affordability, compatibility, and performance you need.

Performance Level 1 crimp caps are chromatography approved, cost optimized products that are suitable for everyday analyses and compatible with all instrument types.

Performance Level 2 crimp caps are manufactured and tested to ensure low bleeding, robustness, and reproducibility of results for your routine GC-MS and LC-MS analyses.

Performance Level 3 caps are specially designed and treated for mass spectrometry applications and contain the lowest amounts of metals, extractables and leachables, ensuring that you consistently achieve sensitivity and selectivity from your most challenging analytes.

Thermo Scientific SureSTART crimp caps are used to seal 11 mm Thermo Scientific crimp vials. Choose from aluminium or magnetic steel caps with septa of various hardness values designed to reduce autosampler needle issues. Use Thermo Scientific manual crimpers and decappers, or Thermo Scientific electronic crimpers and decappers for easy application and removal of crimp caps.

PTFE/Natural Red Rubber Septa

PTFE/Natural Red Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/Synthetic Red Rubber.

 

PTFE/Silicone Septa

PTFE/Silicone is the most versatile septum material offered in various formulations to address specific applications requirements. Extractables from PTFE/Silicone septa are generally at lower levels compared to other resealable materials. PTFE/Silicone septa are formulated for different hardness (durometer) meeting requirements of various needle types. Formulations offering highly consistent performance, lowest background/blank value, and good chemical compatibility, effective sealing/resealing and low penetration force make PTFE/Silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical.

 

PTFE/Silicone/PTFE Septa

A layer of inert PTFE film is laminated to each side of high-purity, medium durometer silicone to form a septum that is resistant to coring, but still maintains good resealing characteristics. PTFE/Silicone/PTFE septa are recommended for the most critical applications such as ultratrace analysis, where there is a longer time between injections. PTFE/Silicone/PTFE septa provide superior performance with any autosampler employing a large diameter, blunt-tip needle. PTFE/Silicone/PTFE septa can have benefits when working with solvents that tend to attack silicone by protecting both sides of the elastomer.
