Inserts, Low Volume for Vials, Plastic. Translucent, 300ul fill volume with a conical, precision point and 6x29mm outer dimensions with plastic spring attached. For use in 2ml autosampler vials. LCMS Compatible. AQ Brand. 1000/CS.
Additional Info:
A high‑volume, glass‑free solution designed for sensitive samples and demanding LC‑MS workflows.
9502S‑02PP‑K inserts are manufactured from ultra‑pure, virgin medical‑grade polypropylene using a proprietary additive‑free molding process. This results in a highly inert insert with minimal extractables, making it compatible with most LC‑MS solvents and ideal for analyses where glass interaction must be avoided.
Each insert offers a 300 µL 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 the sample for improved recovery and consistent needle access across injections.
The integrated spring design ensures proper centering within the vial, reducing needle misalignment and minimizing risk of insert damage. The translucent polypropylene construction includes molded fill lines to support accurate and efficient sample preparation in high‑throughput environments.
