3" / 76 mm Sieve Shaker is designed for small samples of chemicals, minerals, pharmaceuticals, powdered metals, cosmetics, abrasives, ores, foods, and other fine powders. Useful range is 75 µm - 4.75 mm (No. 200 to No. 4 sieve sizes) with woven wire sieves, but many materials may be sized smaller using electroformed sieves.
High frequency, 3600 vpm, electromagnetic vibratory action with 0-100% amplitude control is ideal for fine particle separations. Inline solenoid-actuated tapping action may be used during vibration (60 taps/min.) to speed dry separations. Also use the tap separately for tap-settling and bulk density tests. During dry sieving, the tapping action redistributes the sample on the sieves, and breaks static blinding, helping to clear undersize particles rapidly.
Model SS-3 includes a platform assembly for up to seven full-height. 3" / 76 mm metal sieves and pan or 14 acrylic sieves and pan. The unique sieve clamping mechanism makes insertion and removal of the sieve stack simple and convenient, yet holds the sieves snugly during operation. The captive knobs on the clamping mechanism allow it to be raised with a quick twist, releasing the sieves. The mechanism remains at this height until the knobs are twisted in the opposite direction clamping the sieves in place. The Performer III’s compact size, small footprint, and quiet operation make it an extremely desirable instrument for dry powder sample separations.
Model SS-3 features include an attractive, but rugged coated steel case, on/off controls for vibration and a manual/timed mode switch. A digital timer showing time set and time remaining, the numbered vibration control knob, and simple, efficient electromagnetic vibratory action enable the Performer III to give reliable, repeatable results. Optional stackable acrylic 3" / 76 mm see-through cylinder is helpful for observing sample action while leveling platform or for setting vibration.
