Additional Info:
A reliable, glass‑free solution for samples that interact with traditional borosilicate inserts.
9502S‑02PP inserts are manufactured from ultra‑pure, virgin medical‑grade polypropylene using a proprietary molding process that introduces no additives. This produces a highly inert plastic insert that is compatible with most LC‑MS solvents and minimizes extractables, making it an excellent alternative to glass for sensitive applications.
These inserts provide a 300 µL total fill capacity with approximately 200 µL usable volume and residual volume as low as ~2.5 µL, depending on autosampler configuration and solvent viscosity. The precision conical tip concentrates sample at the bottom for improved recovery and consistent needle access.
The integrated spring design ensures the insert remains centered within the vial, helping prevent needle misalignment and reducing the risk of insert damage during injections. The translucent material includes fill lines for easier sample preparation and handling.
