Micro–spinning Riffler (MSR)
Microscal's Spinning Rifflers (SRs) are manufactured with hopper capacities from 25ml to 40 litres.
Those SRs below ten litres hopper capacity employ a common set of base, motor, and vibratory feeder units which provide for the easy adaptation of riffling volumes of bulk material from five litres down to one millilitre. The appropriate Hopper, Dividing Head, and Collection Vessel packages can be purchased separately to alter the operational capacities of these instruments within the range twentyfive millilitres to fives litres, inclusive, as required.
The Micro Spinning Riffler (MSR) has a bulk capacity up to 25ml and extracts representative samples as small as one–twentieth of the bulk in one pass. The collecting vessels fit together to form a precision integrated dividing head. For 'dense' materials, only the number of samples required need be collected as there is provision to collect the over–spill in the tray that supports the sample collectors. An optional Micro Hopper Assembly is available to enhance the precision of handling the sample and ease the operation of the instrument.
Microscal's laboratory spin riffling instruments are designed to handle materials with a wide range of particle size, cohesion, and density. Powders and granules from sub–micron to 4·75mm (#4) top size can be riffled.
Larger bulks may be sampled using a higher capacity riffler before feeding the resulting portions through a smaller instrument. The representativeness of the final sample is assured even when the ratio of initial bulk to final sample size is 100,000 to 1, particulate properties permitting.
Recombining samples after riffling to generate desired quantities for round–robins, standard samples of materials, or particular tests are distinct advantages of the riffling technique.
All Spinning Riffler instruments between twentyfive millilitres and ten litres hopper capacity are enamelled and equipped with a stainless steel gap–adjustable hopper (which is optional for the smallest instrument, the MSR), an adjustable–rate vibratory feeder with stainless steel feeder chute, synchronous motor turntable drive, and the appropriate collection vessels. All but the MSR have an optional hopper filling aid. The one litre and five litre instruments have a detachable annular dividing head.
Spinning Rifflers fit appropriately into your analytical procedures at the sample preparation stage. Customer's special requirements will be carefully considered. |
