Features and Benefits

• Easy and fast manual handling - Easy handling for left and right handed operators. Sample exchange and sample transport into the heated zone of the oven is provided for by the simple transport system with a magnetic guide rod attached to the glass sample boat.
• Equilibrium conditions are quickly reached - The cold and the hot zone can be purged separately with dry carrier gas using a stopcock. Ambient moisture introduced during sample exchange or addition via the sleeve opening is quickly carried away. Therefore, a stable drift is reached within a short period of time.
• Enhanced operational safety - There is no need to remove the transfer tube from the titration cell after switching off the oven; just open the stopcock to avoid contamination of the oven due to underpressure. Different temperature ranges can be pre-programmed in one cycle. Safety is further improved by automatic shut down after the analysis is completed.
• Ready for use - All necessary parts including the drying unit with gas flow measurement are part of the standard delivery. If purging with dry air is desired, an optional air pump is available.
