VT-2xx-PLUS Series- Advantages and Applications:Anti-corrosion top plate is easy to clean, can stand for high temperature (450 C). Ceramic coated stainless steel top plate is suitable for relatively mild heating, good for small amount sample or a relatively low temperature for large volume sample. Very quick obtainment of desired high media temperature, which low temperature models cannot reach. o High safety protection: When exceeding the safety range of the hot top (50 C more than the setting temperature) or solution (adjustable for VT-240-PLUS), the heating can be shut off immediately and automatically for the safety protection. Two sets of PID parameters (VT-240-PLUS) suitable for quick heating of large volume sample or accurate control of small amount sample.

Technical Description: The set-up consists of a glass column. Arrangement is made for changing the glass column conveniently and filling it with any type of packing required. Air from a regulated pressure vessel passes through a sparker and allowed to enter in the column at the top. Liquid is feed from a tank, fitted with a pump and is distributed at the top of a column using a spray nozzle. Set-up is fully accompanied with manometers required. Solenoid valves are provided in the feed line at the top of column for instant release and close. The flow rate can be adjusted by operating the valves provided in respective line.
