真空控制器 V-850/855 - 智能真空控制
真空控制器 V-850 和 V-855 可普遍用于真空的显示、调节和控制。
集成的通气阀和精密压力传感器具有抗化学腐蚀性，使得该真空控制器成为一种适用于实验室中众多应用的紧凑型装置。
通过新颖的速度控制并结合真空泵 V-700 或 V-710，可以完成无滞后的真空控制。
Reliable and simple to use
Vacuum Controller V-850, designed for standard applications with following functions:
- Vacuum regulation of set pressure with the Vacuum Pump V-700 / V-710 by speed regulation or by switching on and off the vacuum valve. The novel speed control allows a hysteresis-free vacuum control with quiet operation
- Timer function for stopping the process after a preset time
- LabVac function: intelligent control of the pump in a laboratory system with several consumers
- Buchi wizard for a quick configuration using simple menu control
- USB interface for data transfer to PC for storage, evaluation and optimization
- The solvent library is an integrated library with 43 present solvents that can be expanded by the customer. This function considerably simplify the parameter selection
Vacuum Controller V-855, the top model offers additional features as:
- Programming function for pressure gradients for special distillation tasks, ideal for difficult to distil products like foaming extracts or those with boiling delay
- EasyVac function:automatic process control based on vapour pressure detection - it couldn`t be easier. The EasyVac function guarantees the simplified, automatic distillation of individual solvents and complex solvent mixtures, whenever time is the issue during distillation
- Automatic distillation with a stage probe positioned in the rotary evaporator`s condenser. The stage probe is suitable for foaming substances or for maximum solvent recovery
- Repeat function: The pressure curve of a manual or automatic distillation can be stored and retrieved anytime as set point values for optimum process conditions
