Import 9-425 Screw Thread Sample Vial — Buy in wholesale FOB from Supplier in China

The 9-425 screw thread sample vial is a 2 ml capacity chromatography consumable manufactured from amber borosilicate glass conforming to USP Type I standards, with an outer diameter of 11.6 mm and height of 32 mm. The amber glass formulation provides UV light protection for photosensitive analytes, while the 9-425 GPI screw thread ensures compatibility with standard auto-sampler cap and septa systems. These vials are supplied in bulk configurations of 100 pieces per box, with optional writing label and graduations for sample tracking.

The flat-bottom design supports stable placement in auto-sampler trays, and the vial body accommodates削 tolerances accommodate insert sleeves for reduced-volume applications. Material specification to USP Type I borosilicate glass indicates low extractable levels and chemical inertness, critical for HPLC and GC-MS workflows where analyte integrity must be preserved. The amber coloration typically achieves light transmission blocking below 450 nm, though buyers should request specific spectral transmission data for validation against pharmacopoeial light-protection requirements.

Primary import demand originates from pharmaceutical quality-control laboratories, environmental testing facilities, academic research groups, and contract analytical services. The vial's dimensional standardisation permits direct substitution into Agilent, Shimadzu, Waters, Thermo and PerkinElmer auto-sampler platforms without tray modification. Buyers should confirm septa compatibility (PTFE/silicone, PTFE/butyl, or pre-slit variants), cap torque specifications, and whether insert matching is required for sub-millilitre sample volumes. Packaging integrity for international shipment, including inner bag sealing and carton stacking strength, should be verified with the supplier prior to order confirmation.

Ningbo Excellent New Material Co., Ltd. is located at No. 667 Chaoyang Road, Jiangshan, Ningbo, Zhejiang Province, with postal code 315100. The supplier operates under a harbor trust tier classification, and listing data indicates a response rate of 0.00 percent with zero recorded average response hours. This profile suggests limited or unmonitored inquiry-handling history, which buyers should factor into communication planning.

The company specialises in laboratory consumables including chromatography vials, caps, septa and associated accessories, with explicit matching part numbering for integrated supply (HM-0722, HM-0720, HM-2076 and other cap/septa combinations). The listing provides dimensional and material specifications but does not state manufacturing certifications (ISO 9001, ISO 13485), export licence status, annual production capacity, or established client references. Buyers should request quality-system documentation and sample evaluation batches before committing to volume orders, particularly for regulated pharmaceutical applications where supplier audit trails are mandated.
