One supplier for the whole path from raw sample to injection vial: filtration, extraction, vials and labware.
Sample preparation is where most analytical error is introduced and where most laboratories buy from four different vendors. Microlab covers the whole sequence from one catalogue, which is what makes the parts consistent with each other: filters that fit the syringes, vials that fit the caps, septa that survive the sequence.
The problem. Sample integrity is lost before analysis when storage containers leach or leak.
How we handle it. Storage vials, EPA VOC TOC vials, centrifuge tubes and test tubes cover collection and holding across the sample types.
The problem. Particulates block column frits and shorten column life.
How we handle it. Syringe filters across nine membranes in 13 mm and 25 mm, plus vacuum filtration systems for larger volumes.
The problem. A trace analyte in a complex matrix cannot be injected directly.
How we handle it. SPE columns on silica, inorganic chemical, organic copolymer and mixed mode bases, with vacuum manifold systems and empty cartridges for custom packing.
The problem. Unfiltered mobile phase carries particulates straight into the pump.
How we handle it. Membrane filter discs and rolls in nine materials, with glass solvent vacuum filters and multiple vacuum filtration systems.
The problem. Coring drops septum fragments into the sample and blocks the needle.
How we handle it. Threaded vials from 8-425 to 15-425 plus 11 mm crimp and snap top ranges with matched caps, septa and micro inserts.
The problem. Vials tip, get mixed up between batches, or crack in transit.
How we handle it. Vial racks in PP and acrylic, crimpers and decrimpers, HPLC syringes and pipette tips.
Fit and traceability. Vials match caps and septa, filters match syringes, and part numbers stay stable across reorders, which removes a class of problem that mixed sourcing creates.
Yes. The Membrane Selection Guide and Syringe Filter Guider cover the selection logic, and specific applications can be discussed by email.
Trial quantities for method checking can be arranged by email before a bulk order.
