The partial slit septa offers both a penetration aid for thick and dull needles plus prevents evaporation resulting in concentration changes. Only the silicone rubber is cut, the PTFE is not pre cut acting as an evaporation barrier.
A vial that is listed as 2mL is defined as the entire fill volume, with no headspace when the cap is secured. In practice though, a sample solution cannot contain this much volume because of displacement caused by the syringe needle during injection causing the autosampler to inaccurately withdraw the solution. For this reason, a […]
The glass material must contain at least 5% boron oxide to be termed “borosilicate glass”. Other types of glass with less than 5% is often called flint glass or sodium glass.
All of our Vials and Caps are manufactured in carefully controlled conditions to prevent introduction of contaminants to the product. Assembly is performed using powder-free gloves and hair nets in a clean-room facility. Autosampler Vial Product Page
Use a Serum Finish Vial with Crimp Caps While MicroSolv sells 3 types of vial closures and vials; Screw thread, Snap Top and Crimp Top. Crimp Caps will provide the most effective seal with a serum finish, Crimp Top Vial and to ensure the best long term seal we recommend using our Crimp Top (Serum […]
Snap caps are chosen strictly for convenience in ease of applying the cap to the vial, such as in the case of capping hundreds of samples at a time. Screw caps on the other hand provide a better seal (when the cap is properly matched to the vial threading) and is therefore more reliable. An important thing to consider […]
Solid Phase MicroExtraction (SPME) is a technique in which a short fiber coated with a sorbent or polymer quantitatively extracts analytes from a sample matrix. The fiber is then sent to the injector of an instrument such as a Gas Chromatograph (GC) where desorption of the analytes occurs. For this reason, thin septa are highly recommended for SPME […]
Some Compounds adsorb to Borosilicate Glass due to Hydroxyl Groups / Silanols on the Glass Surface and others adsorb due to Hydrophobic Interaction with the Glass itself. Deactivated (surface Treated) RSA-Pro Vials offer the best Glass Options for you since the surface treatment is more complete than any other Glass Vial Available. RSA Vial […]
There are a number of ways to consider the volume of a Vial. One way is if you fill the vial all the way up until there is no headspace when the cap is secured. You could call this a 2mL vial. In practice though, a sample should not contain this much volume because of […]
A simple and quick answer is to meet the different needs of all laboratories and Chromatographers. In 1997, the MicroSolv Brand™ Vials, made with N51A TYPE-1 Borosilicate Glass were the standard of the Autosampler Vial Market and were used by many leading Autosampler Manufacturers as their Brand. Made to be Pharmaceutical Grade Vials equal to […]
Your vials are listed as 12 x 32mm but my autosampler accepts a maximum diameter of 11.8mm. Will they fit?
12x32mm or 2ml vials are listed as 12mm diameter for standardization purposes within the industry. This is a nominal value only (name only) and the exact value is suitable for use with your autosampler. The outer diameter is actually 11.8mm for most 12x32mm vials. Autosampler Vial Product Page
