8mm Amber Screw Top Sample Vial

The 8mm Amber Screw Top Sample Vial from Jiangyin Allpro Polymer Technology Co., Ltd. is a 2 mL capacity borosilicate glass container engineered for chromatography and analytical sample storage. The 8 mm screw thread (8-425 finish) interfaces with standard autosampler caps and septa, while the amber tint blocks UV wavelengths below approximately 500 nm to protect light-sensitive analytes. The vial measures 11.6 mm in outer diameter by 32 mm height, a footprint compatible with Agilent, Waters, Shimadzu and Thermo Scientific autosampler trays.

Construction employs low expansion borosilicate glass (typical coefficient of thermal expansion 3.3 x 10^-6 /K for high borosilicate grades), resisting thermal shock during temperature-programmed analyses. The screw-top closure with precision-moulded threadform provides resealability across multiple injection cycles, a critical parameter for longitudinal sample studies. Standard neck geometry accepts 8 mm open-top caps with PTFE/silicone septa in standard 1.3 mm or 3.0 mm thicknesses.

Primary buyers include pharmaceutical QC laboratories validating drug formulations, environmental testing facilities monitoring pesticide residues, and food safety labs quantifying flavour compounds and contaminants. The vial suits HPLC, GC-MS and LC-MS workflows where sample integrity between collection and analysis directly affects regulatory compliance. Trade terms and precise MOQ should be confirmed directly with Jiangyin Allpro Polymer Technology Co., Ltd., as response signals indicate no recent inquiry activity.

Jiangyin Allpro Polymer Technology Co., Ltd. operates from Room 1009, 27 Huancheng North Road, Kaiy, Wuxi 214400 in Jiangsu Province, China. The company holds a 'harbor' trust tier and 'imported' supplier tier classification, with its profile imported into the marketplace rather than organically verified on-platform. Response rate data shows 0.00% with zero average response hours recorded, indicating no recent buyer engagement through the platform channel. The address places the firm in Wuxi, a city within the Yangtze River Delta manufacturing corridor with established glass and polymer processing infrastructure.

The supplier specialises in laboratory consumables, specifically auto-sampler vials, matched caps and septa, with claims of over 20 years in the sector and proprietary bonded cap manufacturing capability. The source description positions the company as a direct manufacturer rather than distributor, with in-house machining and cleanroom-controlled production environments. No verified certification details, audited factory information, or named client references appear in the available data. Buyers should independently verify ISO 9001 or ISO 13485 quality management system status, as well as specific glass compliance certificates (USP Type I, EP Type I) for pharmaceutical applications.
