Centrifugal Evaporators Eliminate Sample Handling

A new generation of automated centrifugal evaporators for laboratories eliminates manual handling of samples, increasing safety and enhancing productivity.

The Auto HT-12 is a new, robot-ready version of Genevac's (Ipswich, UK) HT-12 large-scale solvent evaporator. The small footprint of the Auto HT-12 allows it to be positioned in any standard fume hood. It allows corrosive solvents such as trifluoroacetic acid, poisons, and solvents from radioactive samples to be safely removed in a remote fume hood without direct operator intervention. This will improve laboratory health and safety without compromising throughput in compound synthesis.

For laboratories looking to accelerate tasks such as compound purification, plate re-formatting, and plate replication, the Auto HT-12 offers many benefits. The high productivity system incorporates remote access doors and an indexing rotor to ensure that sample holders always line up with the robot arm. In addition, full remote control and data logging via the built-in RS232C interface makes it easy to integrate the Auto HT-12 with most laboratory automation systems.

Each Auto HT-12 can be customized by Genevac to suit individual requirements and to provide seamless integration with all commercial robots. Control software allows the Auto HT-12 to automatically detect when the samples are dry and then to shut itself down, thereby safeguarding valuable samples from potential thermal degradation. To allow unattended operation for extended periods, the waste solvent condenser unit is continuous-running and automatically defrosts when full. The evaporator is ideal for drying large numbers of samples of broadly similar mass and format, such as microplates and high-performance liquid chromatography (HPLC) autosampler vials. The system's triple deck rotor has capacity to accommodate 48 shallow-well plates simultaneously.
