This item is a 500W sonicator that includes a ½ in. probe. The probe may accommodate volumes ranging from 20 – 250 mL, depending on the sample type, viscosity, and vessel type. The 750W product option and additional probes are sold separately. There is no specified viscosity range. However, liquids that will not pour or circulate easily may be too thick to processed effectively. Typically, the maximum viscosity at which a material can be processed effectively is 4000 cps.
