Additional Info:
Improve recovery and reduce adsorption for sensitive analytes when working with low‑volume samples in 4 mL vial formats.
9504S‑02ND inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and undergo a deactivation (silanization) process to minimize active surface sites. This improves recovery for polar and adsorption‑prone compounds while maintaining consistent performance in LC‑MS and HPLC workflows.
The precision conical tip concentrates the sample at the bottom for reliable needle access and consistent injections. These inserts provide approximately 250 µL total fill volume with about 125 µL usable volume and a residual volume near 4 µL in most autosamplers, offering a practical balance between recovery and capacity.
The extended 6 × 38 mm design is optimized for 4 mL autosampler vials, enabling efficient use of larger containers for small volume samples. Springs may be required depending on the autosampler and are sold separately; when used, they help center the insert and reduce the risk of needle misalignment or breakage.
