CRS Injection Port Septa
CRS Premium Injection Port Septa
- Center point guides the needle for easy penetration. Reduces needle bending.
- Precision molding assures accurate fit.
- Packaged in glass jars for high purity.
Premium septa are precision-molded with a recess on the injection side, to guide the syringe needle to the same point with every injection.
The CenterGuide™ design requires less force for initial penetration for a smoother feel. Septum life may be enhanced in some applications by minimizing tearing and coring.
The CenterGuide design are available in 5, 9, 11, 11.5, 12.7 and 17 mm sizes for Septa BTO ™, Advanced Green 3 ™, and Marathon™.
Septa BTО ™
Septa BTO is bleed and temperature optimized for the most demanding GC and GC-MS applications: it is the finest GC septum they have tested. Septa BTO is formulated to extend low bleed and outstanding mechanical properties of premium GC septa to the highest-temperature applications. It retains remarkable softness and pierceability at high temperatures, with extremely low bleed, and has been optimized to reduce injection port adhesion.
Marathon Septa™
This is an advanced GC septum for autosampler use, with significantly longer life. The Marathon septum typically achieves 400 injections without failure when used with a rounded-tip (HP-style) needle and autosampler or needle guide. Now you can make extended autosampler runs without fear of sample loss caused by blow-back of leaking carrier gas. The Marathon septum is also ideal for standard manual injection GC and GC-MS.
Advanced Green 3 Septa™ (AG3 Low-Bleed)
The CRS Advanced Green 3 septum was created to combine significantly longer injection life, low bleed and low injection port adhesion. The result is a green septum you can use for all your critical analyses.
