Molded 11,5 mm thermogreen lb-2 x 250

The Perfect Combination of Low Bleed, Thermal Stability, and Easy Puncturability!
Molded Thermogreen LB-2 septa are manufactured from high quality, low bleed material using the same exclusive LB-2 rubber formulation that chromatographers are accustomed to using. The difference is that molded septa, unlike traditional die-cut septa, offer easier installation and better sealing inside the injection port. This is because our liquid injection molding process ensures that every septum conforms to the same shape with crisp, clean sides. This is an improvement over a die-cutting process where septa can become cupped and/or distorted when the cutting surface becomes dull.
