CUSTOM ITEM: Inserts, Low Volume for Vials, Glass. Clear, 250ul fill volume with a conical, precision point and 6x38mm outer dimensions. For use in 4ml autosampler vials. AQ Brand. BULK PRICING.
Additional Info:
Designed for reliable low‑volume analysis in larger vial formats, these inserts provide consistent recovery and performance for routine HPLC and LC‑MS workflows.
9504S‑02N inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and feature a precision conical tip that concentrates sample at the bottom for improved recovery and consistent needle access. This design provides approximately 250 µL total fill volume with about 125 µL usable volume and a residual volume near 4 µL with most autosamplers.
The extended 6 × 38 mm format is optimized for 4 mL autosampler vials, allowing efficient handling of small sample volumes in larger containers. Manufactured in an ISO 9001:2015 certified facility, these inserts ensure consistent dimensional accuracy and dependable performance across batches.
