Unit Dose powder Samplers These samplers with interchangeable dies for unit-dose sampling are available in different diameters, lengths and models. Made of 316 stainless steel, these samplers may have one sample port or multiple sample ports for simultaneous sampling at several locations. Any number of sample ports may be blocked with blank dies. Single, duplicate or triplicate sampling at each sample port is possible. Duplicate and triplicate samples are obtained from exactly the same spot at each sample port with just one insertion of the sampler into the powder bed. Segmented design samplers facilitate sampling from large blenders with roof height limitation. Stainless steel inner shaft is hollow (except in Model IB and 1BB) to make the sampler lighter. Inner shafts, custom-made of Delrin or PTFE - FDA approved white plastics), are available. The samplers are passivated and easily cleanable with a removable conical end piece. Some sizes of standard models are stock items. Others are custom-made and have longer lead times.
Another unit-dose powder sampling technique, involving compaction of the powder sample in the sampling die itself, is described separately under "New Unit-Dose Powder Sampling Technique".
