从China供应商批发进口250ul Micro-Insert With Pp Feet — FOB条款

The 250μL micro-insert with PP feet from DanYang Sunny Glasswork is precision-engineered for laboratory use, featuring a 5.8 × 28mm form factor to fit standard 9-425 vials. Constructed from borosilicate glass tubing, it delivers chemical resistance and thermal stability for analytical procedures like chromatography and spectrometry. The PP feet provide stability during sample processing, reducing the risk of breakage or displacement.

Borosilicate glass 3.3 is the typical material grade for such inserts, offering low thermal expansion and resistance to most acids and solvents. The design prioritises sample recovery, with a conical base that minimises residual volume, a critical factor for trace analysis. These inserts are standardly used in pharmaceutical and biotech labs where consistency in small-volume sampling is essential.

Buyers in research and QC labs source these inserts for applications requiring precise liquid handling, such as HPLC or GC-MS. The inserts are compatible with common autosampler systems, and bulk packaging options are available to suit large-scale operations. Confirm compatibility with your specific vial type and analytical workflow before ordering.

DanYang Sunny Glasswork Co.,Ltd is based in the Economic Zone of Danyang, Jiangsu Province, China. The company specialises in laboratory glassware, with a focus on precision components for analytical instrumentation. Its facility is located in a region known for glass manufacturing, leveraging local expertise in borosilicate processing.

The supplier operates under the harbor trust tier, indicating a verified business presence. While the response rate and average response hours are not publicly available, the address and operational focus suggest a dedicated production line for lab consumables.
