Catalog Number - 9502S-02CP-K

Improve reliability and reduce bubble formation in high‑throughput workflows with a wider‑tip insert design.

9502S‑02CP‑K inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and feature a thicker wall construction combined with a wider conical tip. This design helps minimize bubble formation at the tip, improving injection consistency and reducing variability for samples prone to gas entrapment.

The wider precision cone maintains effective sample concentration while allowing improved needle access and consistent recovery. Residual volume is approximately 2.5 µL with most autosamplers. Polypropylene springs keep the insert centered within the vial, reducing the risk of needle misalignment and insert breakage during repeated injections.

Manufactured in an ISO 9001:2015 certified facility, these inserts provide consistent quality and performance across large batches. This configuration is one of the most popular and economical borosilicate insert designs available, offering an excellent balance of durability, performance, and cost for high‑volume laboratories.
