Abstract: An improved clamp ring system comprises a clamp ring having a wedge shaped seal face; a reactor having a clamp ring mounting recess; a quartz sleeve disposed within the clamp ring mounting recess; a seal being disposed within the clamp ring mounting recess around the quartz sleeve. The clamp ring is removably attached to the reactor near the clamp ring mounting recess such that the wedge shaped seal face compresses the seal against the quartz sleeve.
