Vortex Mixers - SA8 These laboratory vortex mixers allow scientists to control the mixing speed by selecting from 200rpm for more gentle mixing to 2500rpm for vigorous agitation. Choose between `touch' on mode and continuous operation simply by pressing a button on the facia. Robust die-cast body avoids unnecessary movement during use. The ergonomic low profile design makes everyday vortexing comfortable for the user. Integral retort rod fixing allows vessels to be secured above the vortex action for long-term mixing. The SA8 can mix a variety of other vessels when used in conjunction with the SA8/1 accessory pack. Variable speed control between 200 and 2500 rpm Intermittent or continuous mode Stable low profile body Robust die-cast construction
