Additional Info:
Ultra-low Bleed Septa provide less extractables than most septa and is recommended for LCMS. The star shaped (*) slit offers a much greater target area for an autosampler needle to penetrate the septa and offers minimal resistance. It may not reseal as well as other Pre-Slit Septa.
