Thermo Scientific Screw Kits

Thermo Scientific screw kits contain equal numbers of specific types of vials and closures for use with chromatography autosamplers. Available as Performance Level 2 specification certified kits or Performance Level 3 HPLC and GC Certified kits.

Specification certified SureSTART kits are for everyday analysis and the vials and caps in the kit are certified to meet physical parameter specifications as part of the manufacturing process.

HPLC and GC Certified SureSTART kits are tested and certified using GC/FIS LC/UV to ensure that there are no residual manufacturing agents present in the vial that could generate spurious chromatographic peaks and interfere with your results. A certificate is provided with each kit.

Choose from a variety of kits containing short thread screw vials with marking spots in clear or amber glass and polypropylene caps with silicone/PTFE septa designed to reduce autosampler needle issues. Pre-slit and bonded septa options are available. Select kits with SureStop vials and/or AVCS screw caps for effective seals, consistent data, and increased sample throughput.

Features

Performance level 2 kits are specification certified to meet physical parameters
Performance Level 3 kits are HPLC and GC certified and are tested for up to 15 critical physical specifications to prevent technical/performance issues
SureStop vials and AVCS caps features a push-through resistant sealing ring design, controlled septum compression, and positioning flange to ensure an effective seal that eliminates under- and over-sealing, reduces solvent evaporation, and creates less autosampler interruptions

Specifications

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.

Pre-slit PTFE/Silicone Septa

Pre-slit septa are offered in many of the same formulations as for non-slit PTFE/silicone septa and shares most of the physical and chemical characteristics. The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that of a septum without a slit, except that the ability to withstand exposure to aggressive solvents is slightly lessened. Pre-slit septa are highly recommended for Shimadzu, Hitachi, and other autosamplers with thin gauge needles.

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.
