Compatible With / Replaces
This design matches Restek's Thomson SINGLE StEP filter vial line on every published spec we can check: 450µL loading capacity, 120µL dead volume, PTFE membrane, and fit for standard 12 x 32mm autosamplers including UHPLC. We're calling this designed to be compatible with the Thomson SINGLE StEP PTFE filter vial format, since housing wall thickness and exact cap torque spec are the only details we haven't independently confirmed.
FAQ
- What's the fill volume?
- 450µL loading capacity, with a low dead volume of 120µL so you lose less sample.
- What's the septa/cap material?
- A pre-slit PTFE/silicone cap, designed to reduce broken autosampler needles and cored septa.
- What autosamplers does this fit?
- Standard 12 x 32mm autosamplers, including UHPLC instrument trays.
- Can these handle particulate-heavy samples?
- They're recommended for samples with less than 10% solid particulates. For heavier particulate loads, a standalone syringe filter may be a better fit.
- How are these packed?
- 10 packs of 100, 1,000 vials total per case.
