Valuable time can be taken up mixing bottles and flasks by hand. Let our flask shaker take the strain. Holding up to eight flasks or bottles, up to 500ml capacity, it creates a vigorous mixing action by simulating hand shaking. It is especially useful for applications where prolonged shaking is required as it can be left on continuously and won’t get tired! Robust construction, mounted on four rubber feet to absorb vibration and prevent unnecessary movement on the bench. Analog timer covers 10 to 60 minutes with a manual override. Electronic feedback control ensures a constant speed irrespective of load. Supplied with two side arms, eight clamps and Allen key. An optional extension kit is available which consists of two extension arms and four extra clamps increasing the capacity to twelve bottles or flasks.
