JG Finneran 4035-630Z Deactivated Glass Flat Bottom Insert Without ID Ring - 350µL Capacity (Pack of 1000) - Ideal for HPLC, GC, and Laboratory Sample Analysis

Product Description

Limited volume inserts are available in a variety of designs to accommodate all size vials and all types of autosamplers. Polymer Top Springs, bottom springs and metal springs act as shock absorbers that protect against breakage if the needle "bottoms out". Plastic flanges adjust smaller volume inserts to fit the vial neck. Conical bottoms permit complete sample removal. Flat bottom inserts are an economical alternative.
