This range of 1200°C and
1500°C horizontal vacuum tube furnaces offers vacuum levels of better
than 10-5mbar with a clean empty worktube.
The vacuum system and all controls are housed in the
base with one end of the worktube joined to the vacuum system via a
stainless steel elbow. Access to the tube is via the other end which
is fitted with a removable stainless steel flange. radiation shields
are provided for both ends of the furnace to ensure maximum temperature
uniformity with minimum loss of pumping speed.
These furnaces include two stage sliding vane rotary
pump, water cooled oil diffusion pump, high vacuum baffle valve, roughing/backing
valve(s) and Pirani and Penning gauges.
A number of special options is available including
gas systems, automatic/semi-automatic vacuum systems, air cooled diffusion
pump, cooling water failure alarm and custom built designs.
