Aijiren 15-425 threaded caps with silicone septa are designed for HPLC autosampler bottles to ensure the stability and integrity of samples during storage and injection. These caps are made of polypropylene (PP) material, which has excellent chemical stability and sealing performance and is suitable for a variety of laboratory environments.

10-425 Screw Neck 2ml HPLC Autosampler Vial design is characterized by universal ease of use, especially the use of automated sample introduction systems. Aijiren 10mm 2ml HPLC autosampler vial is generally made of high-quality imported expanded borosilicate glass tube. The high-cost performance of this material is the first choice for throughput analysis. The matching polypropylene bottle cap is chemically compatible, suitable for most chromatographic applications, and suitable for 6mm diameter micro-insert. the wide mouth of 10-425 vials can get a larger injection range, so this kind of bottle is often used to repeatedly clean the residual solution on the automatic injection needle.
