Thermo Scientific Chromatography Vials and Closures Buying Guide. Maximizing productivity and achieving reproducible results in chromatography requires a fully optimized workflow from sample through assay. With that in mind, the Thermo Scientific™ SureSTART™ portfolio supports sample security and integrity with a variety of products to fit

Overview Diferent septa material for LC and GC applications There are many diferent 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

Oct 21, 2022 · Oct. 21st, 2022. The septa and vial caps are essential parts of HPLC vials. The vial cap serves as a barrier, keeping outside contaminants out of the vial and preserving the integrity of the sample. The septa, a seal between the injection needle and the vial composed of silicone, PTFE, or rubber, ensure accurate and exact sample injection.

The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down. Use the simple online Thermo Scientific SureSTART Selection Guide to find the right septa and vial for your analysis.

Chemically resistant but for one time use only with no ability to reseal. Free of fluoropolymer coating, so suitable for PFOA analysis. 20 mm seal selection for headspace and sample preparation applications.

4 mL vials , 12 mL vials, 22 mL vials, or 40 mL vials are available. Choose from either clear glass storage vials or amber glass storage vials. Open top storage screw caps are lined with PTFE/silicone for chemical resistance and excellent seal. Closed storage screw caps (closed storage caps) are PTFE-lined and available together as storage vial

Apr 18, 2023 · HPLC vials are of great significance for chromatographic analysis, especially 2ml vials. They have different materials, sizes, and designs and can be used in different applications. Let’s discuss different types of 2ml HPLC vials, their features, and advantages, how to choose the right vial, and their maintenance and storage. II. 2ml HPLC vial

Chemically resistant polyethylene septa are usually molded into single-piece caps . The surface for needle penetration is 0 .01" thick, allowing for use with most HPLC autosamplers . Polyethylene septa are not resealable and are intended for single injection use with aqueous based sample mixtures . Polypropylene (PP) Septa

The vials are removed from the lyophilizer, capped, and sealed to ensure sterility. Stoppers are vented and fall into 3 categories: single vented (igloo), dual vented, or 3-legged configurations (Figure 1). Figure 1. IGLOO, 2-legged, and 3-legged Stoppers (20 mm) The stopper design has no impact on the resistance of flow of water vapor during

Vials and Closures Thermo Scientifi c Chromatography Columns and Consumables 2014-2015 2-102 Chemical Resistance Reference Chart This chart provides a guideline for the chemical resistance of materials used for vials and closures. Because so many factors can affect chemical resistance, it may be necessary to test your product under

The 1.5mL 9mm Short Thread Vial ND9 offers numerous features that make it a reliable and flexible storage option for sample material. Compact size, compatibility with various analytical techniques, user-friendly design, high-grade materials, secure sealing options for sample visibility, and cost-effective packaging options are among its outstanding characteristics.

Precleaned, EPA certified assembled kits; includes 40 mL screw vials and 24 mm. open top screw caps. 0.3 and 1.5 mL screw top vial-cap kits for analysis of small sample volumes. For use with environmental analyses under EPA regulations. Highest levels of sample security and integrity. Precleaned.

Jul 26, 2022 · The pipette tip is also an important detail to consider for HPLC analyses. Low retention tips are best when working with solvents of different viscosities, as they maximize sample recovery. Sample contamination can also occur as a result of leaching from the pipette tip. As such, tips with high chemical resistance preserve sample integrity. Step 4.

The septa are conditioned to provide the lowest level of chromatographic extractables. Choose these products for ultimate method performance and high levels of and sample security and integrity. All SureSTART vials, closures, and septa are certified to meet physical parameter specifications as part of our manufacturing process.

Polypropylene is by far the best option for plastic vials due to its good chemical resistance for short term storage. They can also be incinerated while sealed limiting exposure to hazardous materials. View vials and filter by vial material. 8) Choose the best vial color for your sample. Both plastic and glass vials come in clear or amber options.
