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 in small timed increments to display the magnitude of potential sample loss […]
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 […]
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. […]
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 […]
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. They are provided in 4 different “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 bottle provides. CLICK ON GRAPHICS TO […]
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 […]
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.
