Import 6mm Vial Inserts — Buy in Bulk from Supplier in China

The 6 mm vial inserts from Hangzhou Alllabware Scientific Co., Ltd. are borosilicate glass or soda-lime glass precision inserts designed to fit inside standard scintillation or sample vials with a 6 mm internal neck diameter or insert-specific compatibility. These components reduce dead volume in chromatography and mass spectrometry workflows, allowing smaller sample volumes to be processed without switching to micro-vials. The 6 mm dimension refers to the outer diameter of the insert body, which must mate closely with the parent vial's inner bore to prevent leakage or evaporation. Hangzhou Alllabware manufactures from Zhejiang Province, a region with dense clustering of laboratory glassware and analytical consumables production.

Glass vial inserts are typically fabricated from Type I borosilicate glass (3.3 expansion coefficient) for thermal shock resistance and chemical inertness, or from economy soda-lime glass for non-critical applications. Standard wall thickness for 6 mm inserts ranges from 0.5 mm to 1.0 mm, yielding internal volumes from 100 microlitres to 500 microlitres depending on insert length. Bottom configurations include flat, conical (V-bottom) and rounded (U-bottom) profiles, with conical designs preferred for maximum sample recovery in HPLC and GC autosampler systems. Surface treatments such as silanisation may be offered for adsorption-sensitive compounds, though this is not confirmed in the source data and must be requested from the supplier.

Buyers include pharmaceutical QC laboratories, environmental testing laboratories, university research facilities, forensic toxicology labs and contract research organisations running high-throughput chromatography. The inserts are consumable items with repeat purchase cycles tied to sample batch volume. Hangzhou Alllabware's location in Hangzhou provides proximity to Shanghai and Ningbo ports, facilitating export logistics. Specific MOQ, pricing, certification status and lead time are not stated in the available data and require direct confirmation with the supplier. Compatibility with specific autosampler brands, such as Agilent, Waters or Shimadzu systems, should be verified before volume commitment.

Hangzhou Alllabware Scientific Co., Ltd. is located at No.168, Huayuangang Road, Hangzhou, Zhejiang 310011, China. The supplier holds an imported tier and harbor trust tier classification, indicating a registered presence without advanced verification or transactional track record on the platform. The response rate shows 0.00 percent with zero average response hours, suggesting either a new listing, a dormant account or incomplete data capture. No factory audit, ISO certification display or named reference customers appear in the profile provided.

The company positions itself in the analytical consumables sector, specifically vial inserts and related laboratory glassware. The profile does not state year of establishment, registered capital, employee headcount, annual turnover, export licence numbers or R&D capabilities. Buyers should conduct independent verification through the Zhejiang Provincial Administration for Market Regulation, request a copy of the business licence with laboratory equipment or glassware manufacturing in the scope, and seek evidence of quality management system certification such as ISO 9001 or ISO 13485 if claiming medical or diagnostic applicability. Direct communication to assess technical knowledge of chromatography consumables is recommended before trial ordering.
