Laboratory evaporator SP 1000 M

thin-film

The short path distillation system is designed for the distillation of thermally sensitive products under vacuum. The system is used for organic products of high molecular weight and high viscosity at operating temperatures. The evaporator surface consists of a vertical double mantled glass cylinder, heated by circulating thermal oil. The product is being spread to a thin film on the inner surface of the evaporator by means of rotating PTFE wiper elements. The wipers are being pressed to the inner wall of the surface where they produce a continuously distributed thin liquid film. The condenser is arranged vertically in the center of the glass evaporator to reduce the distance for the vapors and to prevent any pressure drop by large transfer spaces. It is tempered by liquid flow to condensate the evaporated product. This technology enables the operation at high vacuum to reduce the boiling point of thermally sensitive extracts without decomposition. The rotating wiper basket is made of stainless steel AISI 316 and equipped with PTFE (Teflon) roll wipers. PILODIST SP1000M is offered as a turn-key system including complete vacuum accessories and three high capacity thermostats to temper feed-vessel, inlet line, evaporator and the condenser including outlet line. The residue outlet is also tempered to prevent solidification of very heavy, waxy residues. The SP1000M is a system for batch-wise operation and the budget friendly alternative to our fully continuous flagship SP1000CC. Once having installed and operated the system at customers side it can later be upgraded to the continuous more sophisticated version SP 1000 CC.
