Description

• Molded Septa offer easier installation and better sealing inside the injection port
• A liquid injection molding process ensures that every septum conforms to the same shape with crisp, clean sides
• Injection hole helps guide the syringe needle to puncture the same location every injection
• Benefits of the injection hole include minimal coring and less septum fragments that could contaminate the inlet liner
• High puncture tolerance makes these septa ideal for use with autosampler injections, manual injections, and/or SPME applications
• The useable inlet temperature range of 100-350°C is adequate for most GC applications
• Rubber formulation is exclusive to Supelco
• Strict tolerances (diameter, thickness, injection hole) due to constant dimension of the mold itself
• Ultra low bleed over a wide range of inlet temperatures
• No foreign substances/powders, which could contaminate the inlet, are used during manufacturing
• Fully tested for bleed and contamination
• Pre-conditioned and ready to use
• Ideal for use with low bleed GC-MS columns
