Adsorption in Borosilicate Glass Vials is Time Dependent. But can be Fast. We have shown from previous experiments of how concentration of certain analytes can be adsorbed to glass surfaces over time which is an indicator of potential problems for the laboratory for many other analytes as well. In this experiment, a sample was taken […]
Yes. The Soft-Guard™ Septa will outperform most septa and caps on the market when used with most LCMS applications. For very sensitive LCMS/MS applications we recommend our Advanced Quality, AQR™ septa and caps which is colorless, ultra-pure and designed for the most critical chromatography applications. The AQR™ cap incorporates all the benefits of the Soft-Guard […]
While BASIK Brand Screw Caps are Not designed for Ion Chromatography; it may work for some Applications. However, we suggest for Maximum Performance in IC to use our Ultra-Pure Polyethylene Screw Caps. Note that these Caps, are a Single Use Cap and will not reseal after injection. Ordering Information
No, the Plastic Springs are only Available assembled with the small volume Vial Inserts, including the Springs from the RSA Inserts shown below. RSA Brand Glass Vial Insert and Spring RSA Glass Small Volume Insert Product Page Inserts Product Page
Can the autosampler vials be used in a centrifuge? What is the maximum centrifugal force that can be used?
Autosampler vials are not designed to be centrifuged so we cannot support it with the exception of the MRQ & Max Recovery vials due to their thicker walls and “single piece” construction (AQ brand, RSA or RSA-Pro). They can withstand g forces up to 6,000 x g when used in a compatible centrifuge and adapters. The […]
Concern if RSA™ vials been discontinued and did RSA-Pro™ change to RSA-Pro X™ is answered. No, RSA™ Vials the non-surface treated, hydrophilic, borosilicate glass vials do not adsorb basic compounds are still available and remain one of the most popular vials in the market today. They and are still an excellent choice for compounds that […]
It is important to understand that crimping a cap could result in an inadequate seal if not done properly. Follow the steps shown below to achieve the best seal. You need a calibrated crimping tool (https://mtc-usa.com/Crimping-Tool) This means that the chuck has to be adjusted every 10 -15 crimps with the adjusting tool it comes with. […]
RSA-Pro X™ – Hydrolytically Stable Glass Vials & Low Volume Glass Inserts Silanol groups (Si-OH) on the surface of glass has been known to cause not only empirical quantitative loss but also inaccurate quantitation, vial to vial and run to run over time. Silanol sites are very reactive and can produce among other things, imprecise […]
The idea of a filter membrane that fits directly onto the autosampler vial like a standard cap may seem like a streamlined, labored-saving design. However, there are several practical issues associated with the physics of using such a cap: 1. The air that is required to “push” liquid through the filter goes into the vial; this […]
For both of two autosampler vials, the total Residual volume is 2 μL. The Dead Volume is analogous to Residual volume.
MicroSolv has the world’s most comprehensive assortment of Vials, Caps & Inserts for every chromatography need. This assortment of solutions are provided in 4 different “ type tiers” or levels to suit every lab’s analytical and budgetary requirements. Each tier/level is described below including the value each type of vial, cap, limited volume insert or storage […]
Amber Glass Vials are manufactured with 51-Expansion, Borosilicate Glass, and according to the recommended exposure this glass is rated to 230°C for normal service or 490°C for extreme service. Please always verify the temperature limits of Caps and Septa, as each material will have different specifications. We do not recommend pressurizing Autosampler Vials above 1 […]
The first number refers to the “Major Diameter” of the Screw Thread, (Major Diameter is the OD / outside diameter of the screw top vial (not the OD of the vial) at the thread line, measuring on the outside of the threads, Minor Diameter is the smaller diameter, measuring OD between the threads). We use […]
The U-2D™ Inserts can be written on using our laboratory markers found HERE. Also, the U-2D™ Racks have positions that are marked with alpha-numeric embossed markings on the sides of the racks.
Liners or Septa? A liner can be made of the same material and be the same or different thickness as a septum but it is installed in a solid top cap and therefore cannot be pierced as Septa do. Its primary function is to keep the sample from escaping the vial while the cap is […]
What is the difference between RSA-Pro™ and vs the new RSA-Pro X™ surface treatments? The biggest difference is that RSA-Pro™ surface treatment incorporated a vapor deposition type process that used ionic bonds with silanes to achieve hydrophobicity of the RSA glass. RSA-Pro X™ surface treatment uses a very different, proprietary process of covalently bonding hydrophobic […]
Both vials are designed so that the maximum recovery of precious samples can be achieved without the use of vial inserts. The difference between the two is important when different autosamplers with different types of needles are installed. MRQ™ can be used with side port needles such as in the Waters™ WISP© or with bottom port needles in […]
MicroSolv Brand Autosampler vial screw caps are designed for use at room temperature with a typical temperature range of 0°C to 60°C . Caution: An extreme temperature range of -55°C to 220°C is possible, however the silicone / PTFE septa will be able to withstand a higher temperature before structural integrity of the polypropylene cap is lost.
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 […]
