VJ Tech provides a compact sieve shaker which has been specially designed and manufactured to combine the advantage of low cost with the benefits of a well designed and engineered shaker, incorporating many features usually found only on larger more expensive models. It is ideal for the laboratory or plant since it is compact and genuinely portable. There are no moving mechanical parts and so consequently it is very quiet in operation and maintenance free. The sieve stack is held firmly in position between the location and clamp plates by an efficient, simple to use adjustable clamp system and the anti-vibration feet ensure good stability.
