Case
Metal caps offer the widest range of temperature tolerances and are very resistant to fracture from impact. Metal caps are great for industrial and food applications. A metal closure is manufactured from either steel (coated with anti-corrosive coating of either chromeplate or tinplate) or aluminum.
These one-piece microvials have a very low residual volume due to a specially shaped deep and narrow inner reservoir which collects the liquid in the base so compatible autosamplers can collect all but 1-2 microliters of sample while having a total sample volume of 1.2mL.
We supply the following types of sample bottles: vials with crimp top and corresponding caps screw thread vials and srew caps sealing disks for individual combinations of cap and seal Except for a few frequently used combi packs, vials and caps can be ordered separately, thus allowing a wide range of possible combinations.

expected from 33 type vials, as the coefficient of mean linear thermal expansion is the lowest for the basic tubes used for vial manufacturing, as well as the hydrolytic resistance acc. to ISO 719, acid resistance acc. to DIN 12116 and alkali resistance acc. to ISO 695. Aside of 33 type vials we tested vials of the 51 and 70 type, in order
Micro inserts are used to reduce the volume of standard sample vials for application with very small sam-ple volumes. Vials are closed as usual. As an alternative for small volumes you may use the sample vials with conic inner shape (conic vials). Crimp caps can be used for crimp top vials or vials with snap ring design. They are available with
• TOC certified kits contain 40 mL glass screw vials and pre-assembled 24 mm screw caps with bonded, high purity silicone/PTFE septa. • Each lot is tested and certified to contribute <10 ppb or <20 ppb background Total Organic Carbon levels via gas chromatography. • Low TOC background is ideal for preparation and storage of standards.
Jun 02, 2020 · Concepts of Fiber–Sample Distance and Fiber Penetration Depth. To perform HS-SPME experiments, samples were introduced in 20 mL (23 × 75 mm) HS vials sealed with an 18 mm HS screw cap (Phenomenex, Torrance, CA, USA) and stirred at 250 rpm; vial volume and stirring speed were defined according to the most common conditions reported in 200 HS-SPME papers published in 2019 ().
Screw thread vials and caps provide low evaporation, reusability, less hand injury during manipulation than crimp seals and require no special tools. All screw threads vials and caps are differentiated by their thread finish as defined by the Glass Packaging Institute, GPI. For screw thread vials, a two part number is assigned.
very low and very high pH applications. Clear Glass Vials can be made from different coefficient of expansion glass; most notable 33-expansion and 51-expansion glass. All Aijiren Technology Clear Glass vials are made from of 33-expansion glass. The alkali content is low and 33-expansion glass has very low free ion content. Figure 1.
Screw caps come in different sizes identified by the outer diameter of the mouth of the vial. Screw caps used on chromatography vials are either 8mm, 9mm, or 10mm, with 9mm being the most popular size. Vials can have a standard opening (5mm) or wide-mouth opening (6mm) depending upon the cap type to be chosen.
03 Oct 2017. Solvent Choice for GC Injection. I guess we all have our ‘go to’ solvents for our work in GC, and most of the time this will be based on the availability of the solvent and the chemical nature of our samples. Polar samples (analytes) generally need a more polar solvent (methanol for example) and less polar analytes a less polar
Chromatography - Focus on vials, closures & chemicals. In chromatography, a broad variety of glass or plastic vials are used as Hydrolytic class glass is very hard and has a low expansion coefficient even. Aijiren Tech Sample handling premium products - MZ
includes caps and septa screw thread vials that are supplied in a storage tray. Vials have a wide opening, 2 mL capacity and measure 12 x 32 mm. Vials are supplied ready to use saving time and labor. Trays are stackable for easy storage and hold vials upright for filling and maintaining sample…
