Capability

Precision, sterility, and traceability — by design.

We treat glass as an engineered material, not a commodity. Our process controls the three variables that decide whether a vessel performs: composition, geometry, and the environment it is finished in.

01 — Materials

Type I borosilicate

We work exclusively in 3.3 expansion borosilicate — the international reference for thermal-shock resistance and chemical inertness. Low alkali migration, predictable expansion, stable across repeated thermal cycling.

02 — Process

Controlled batch finishing

Vessels are washed, depyrogenated, and finished under filtered, positive-pressure airflow. Each lot carries a batch record from anneal through final inspection, so traceability never breaks.

03 — Logistics

Protected cold-chain shipping

Orders are packed to survive transit, not just the warehouse. Foam-seated trays, tamper-evident closures, and documented packing standards for refrigerated and ambient consignments alike.

Inventory

A curated range of analytical hardware.

Informational overview. Full specifications, dimensions, and grading notes are listed in the catalog.

Borosilicate storage vials

Crimp-top and screw-thread formats in 2 mL–30 mL. Amber and clear, with matched closures and inert liners. Supplied sealed, ready for a sterile field.

Graduated pipettes & micro-tubes

Serological pipettes, fixed-volume transfer tubes, and conical micro-tubes. Clear graduations, low static, certified nominal volumes per lot.

Sterile closures & septa

PTFE/silicone-faced septa and aluminium crimp seals engineered for repeat-access integrity and minimal coring.

Protective & cleanroom supplies

Nitrile gloves, lint-free wipes, and 70% USP-grade isopropyl presentations for maintaining a clean working field.
