The Stuart® SHM1 is a powerful, variable speed, homogeniser. The high-speed, high-torque motor makes the unit ideal for most homogenising applications. During operation the rotor shaft, which is directly coupled to the motor, spins at up to 35,000rpm. The tube assembly that fits around the shaft remains static and as the rotor shaft spins, within the tube assembly, it creates a pumping action drawing the sample into the open end of the tube, or probe, and forcing it through the windows at the bottom of the tube assembly. This shearing action reduces the particle size of the sample. In addition the speed differential between the rapidly moving rotor, and the static tube assembly creates cavitational force, further dismantling the sample to additionally reduce particle size.

The SHM1 is lightweight making it comfortable to use, and most samples can be processed within thirty seconds. For longer processing the unit can be stand mounted using the included post clamp assembly. A retort stand is available separately.

The SHM1 can accommodate a selection of stainless steel probes for larger and tougher samples and also our polycarbonate disposable probes. The SHM/ADAPT adaptor is required to use the disposable probes with the SHM1, however each purchase of a SHM1 incudes a complimentary SHM/ADAPT adaptor. Disposable probes are suitable for hard tissues and ideal where cross contamination is of concern. If necessary disposable probes can be easily dismantled and autoclaved up to seven times. Through careful selection of probe type, samples of 0.03ml to 100ml can be processed.

All Stuart® homogenisers are supplied with a tool kit for dismantling the rotor probes for easy cleaning.
