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.

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 […]
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 […]
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.
