J.G. Finneran* Limited Volume, Snap Seal* and R.A.M.*, Conical Glass Inserts

Inserts are available preassembled with a polymer bottom spring or patented Top Spring™. The polymer spring acts as a shock absorber that protects against breakage if the needle bottoms out. The conical design permits complete sample removal. The Step Insert sits precisely in the neck of the vial, thus eliminating the need for metal or plastic springs. Limited volume inserts are available silanized or precleaned.
