Catalog Number - 95001-04ND

Maximize recovery and minimize adsorption for ultra‑low volume, high‑sensitivity analytical workflows.

95001‑04ND inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to reduce active surface sites. This treatment significantly improves recovery of polar and adsorption‑prone analytes while maintaining excellent consistency and durability through a thicker wall design and mandrel‑formed precision tip.

The high‑precision conical tip concentrates the sample at the bottom, enabling reliable needle access and consistent injection performance even with very small volumes. These inserts provide approximately 50 µL usable volume with a residual volume near 2 µL in most autosamplers. Polypropylene springs ensure proper centering within the vial, reducing needle misalignment and minimizing the risk of insert breakage during operation.

Manufactured in an ISO 9001:2015 certified facility, these inserts deliver consistent performance batch‑to‑batch. Their versatile design allows compatibility across multiple vial formats while maintaining optimal recovery and reproducibility for demanding LC‑MS and HPLC applications.
