Model 28334-U -Molded Thermogreen LB-2 Septa, With Injection Hole

The useable inlet temperature range of 100-350 °C is adequate for most GC applications. Don′t be fooled by other septa that advertise a maximum temperature of 400 °C! Tto make septa with high thermal limits, they must be made stiffer, resulting in septa that are harder to pierce and easier to core! Our molded Thermogreen LB-2 septa offer the perfect combination of low bleed, thermal stability, and easy puncturability.

• Rubber formulation 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 (100 °C to 350 °C)
• No foreign substances/powders (which could contaminate the inlet) are used during manufacturing
• Fully tested for bleed and contamination
• Already conditioned, ready to use
• Ideal for use with low bleed GC-MS columns
