Low bleed high temperature septa are designed for the lowest bleed possible at temperatures of up to 400 °C. They can be used in combination with Mass Spectrometers or in applications where septa bleed interferes with trace analysis. These septa are typically used for manual injection applications.

• Extended temperature range, low-bleed
• Virtually eliminates injection-port sticking
• Each batch GC-FID tested
• Ideal for use with low-bleed, 'Mass Spec' capillary columns

The 5, 9, 11 and 11,5 mm diameter septa are available with a center depression which guides the syringe needle to the same injection point, extending septa life and reducing needle bending.
