Concentration solutions
  • Description




MULTIVAPThe new LabTech MultiVap8 automatic parallel system increases the capacity and sample throughput in laboratories and maintains quality and lower costs. With this system users can evaporate to solid state or concentrate into a fixed end-point volume. A compact solution compared to conventional rotary evaporators, with the possibility to be used outside fume hood thanks to the integrated vapor exhausting system.

Technical features

Vortex nitrogen purge to get the highest concentration efficiency. The location and direction of nitrogen purge can be adjusted according to the concentration cup size and sample volume
Operations visible through the backlit front window. Sample cups do not need to be handled to check the residual volume
Sealed concentration chamber including a high efficient vapour exhausting system
Built-in digital nitrogen gas regulator to control the nitrogen flow and the evaporation speed
Automatically detecting the liquid endpoint
8 positions supporting 50 & 200ml concentration cups simultaneously
8 infrared sensors for single cup volume control
Possibility to place concentration cups in the liquid handler of GPC/SPE directly
Liquid bath with temperature control range from ambient to 99.9°C
Low liquid level and pressure alarms to ensure safe operations
Touch screen control interface
