For the gentle homogenisation of biological samples or for grinding tough; rigid material which is difficult to break down. Complete with load-compensating drive unit and universal quick-action chuck; transparent plexiglas cooling jacket and multi-purpose spanner for centering homogenising vessels of varying sizes. Portable; but highly stable and vibration-free due to its triple-post frame construction; and easy to use. Provides high torque; even at the low speed range; ensuring extremely powerful homogenising. Continuously adjustable speed range: 40rpm to 3000rpm. Provides reproducible homogenising by maintaining constant rotational speed; which is shown on an easy to read; 4-digit LED display. The fast-action clamping chuck with hollow shaft permits rapid and easy replacement of the pestle and allows pestles with longer shafts to be used. We highly recommend using a quick-grip chuck for glass pestles to minimise lateral movement (and therefore strain) of the glass shaft. The cooling jacket incorporates a clamping holder suitable for Eppendorf test tubes and homogenising vessels with outside diameters from 10mm to 40mm. Sample cooling is easily achieved using ice; which can be introduced into the cooling jacket through a screw capped opening. The homogenising vessel moves up and down in conjunction with the cooling jacket platform and is raised and lowered using a lever jack. The long lever facilitates thorough homogenising without much effort. For 230V 50/60Hz; 300 W single phase supplies (optionally available for 115V 50/60Hz). Supplied with: schuett homgenplus homogeniser drive unit with universal keyless chuck; incl. cooling vessel; 1000 ml and universal chuck set (consisting of 6 sizes). We also offer a sterile alternative for use in a glove box and with infectious material. Details on request.
