For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.
Ideal for demanding MS work. LCMS Certified Vials are suited for analyte concentrations in the 100s ng/mL concentration. Waters LCMS Certified Vials are tested by MS scans from 250 to 1000 m/z with specifications set on the total ion count and presence of clusters in the high mass range. This chromatogram shows a comparison of typical MS scans
• Pre-assembled caps and septa are convenient and minimize contamination from handling Plastic Vials • High clarity plastic vials for easy sample viewing • Low extractables polypropylene provides the broadest compatibility and low non-specific binding • Variety of closure options available Snap-It Caps • Inexpensive single use closure
The septum forms a barrier between your sample analyte in the vial and the outside atmosphere. This barrier protects your sample from external contamination while allowing a needle (from a manual or automatic syringe) to enter the vial, and extract the sample for the next stage of separation.
Sample vials may also be sterile or pre-cleaned for conformity to various certification and compliance requirements. Glass sample vials made from Type 1 Class A borosilicate glass have low extractables and superior chemical resistance, others made from soda lime glass are for less demanding applications. Plastic sample vials are manufactured
Different septa material for LC and GC applications There are many different types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa When selecting which septa is right for your experiments, it
Volume 35 mL; mixing load approximately 15 mL. For use with SPEX SamplePrep 3112 or 8006A methacrylate balls. Polypropylene Vial w/Cap 1.5x3 in.: For wet or dry mixing. Vial size 11/2 in. (3.81 cm) diameter x 3 in. (7.62 cm) long. Polyethylene vial with attached cap. Volume 75.
Each lot of certified kits is tested by HPLC/UV and GC/MS against 15 critical parameters. Certificate of Conformance included in every pack. Kits are delivered shrink-wrapped to ensure product cleanliness. Superior quality 1st hydrolytic class glass (Type 1) in clear and amber. Fixed insert or conical base vials for limited volume sampling.
used for caps include polypropylene, low density and high density polyethylene, and urea resin. Materials commonly used for septa include PTFE, silicone, natural red rubber, butyl rubber, Viton, polypropylene and polyethylene. PTFE is often laminated onto the sample facing side of a resealable septum to improve solvent exposure characteristics
The dram/sample vials are available in clear or amber Type I borosilicate glass assembled with solid top or open hole black polypropylene screw thread closures. The solid top closures are lined with PTFE/F217 material and the open hole closures have PTFE faced silicone septa assembled in the
These sample vials are made from low extractable borosilicate glass to provide superior chemical resistance. Vials are available with or without caps and a choice of liners. PTFE faced rubber lined caps provide an inert and chemically-resistant barrier for reactive samples. Caps with 14B rubber liner are suitable for aqueous samples.
extractables and leachables contaminating the drug product. Siliconized stoppers also tend to stick to the freeze dryer shelf (Figure 2). The degree of stoppers sticking to the shelf is dependent on the compression force of the stoppering ram and the duration of compression. Factors to Consider While Selecting Stoppers for Lyophilized Vials
Thermo Scientific. 9mm Clear Glass Screw Thread Vials are 2mL, 12x32mm and built with Advanced Vial Closure System (AVCS). This innovation not only prevents septa push through, but provides a stop point for the cap to prevent over- or under-tightening and provide an optimal, consistent seal every time. Vials are made.
Thermo Scientific Economy Certified VOA Vials with 0.125" Septa are designed for water sample collection for volatile organic analysis (VOA). You get our standard 40 ml VOA vials, processed and Certified to meet EPA Performance Based …. More Product Information.
