Product description
A lab scale pharmaceutical aseptic separator is a closed vibratory filtration and drying system designed for sterile batch processing of pharmaceutical solids. The system integrates filtration, washing, dewatering, and vacuum drying within a sealed chamber to maintain aseptic processing conditions. This type of equipment is typically used in pharmaceutical research, pilot laboratories, and small-batch production environments where product containment, sterility, and controlled processing are required.Technical overview
The system combines vibratory screening technology with vacuum drying and inert gas flow to process pharmaceutical slurries within a single sealed unit. Liquid-solid separation occurs on a screening surface, allowing the filtrate to pass through the screen while solids remain on the screen deck. Once the filtration step is complete, the retained solids can be washed and dewatered without transferring the material to another system. Drying is performed under vacuum conditions while controlled gas flow promotes moisture removal and gentle particle movement. The compact design and batch capacity make this configuration suitable for pharmaceutical laboratory operations and early-stage process development.Operating principle
The separator operates using controlled vibratory motion applied to a screening surface inside a sealed chamber. Slurry is introduced into the chamber and distributed across the screen deck. During filtration, liquid passes through the screen openings while solid particles remain on the surface. The vibratory motion keeps the product moving gently across the screen, preventing clogging and improving liquid removal. After filtration and optional washing steps, vacuum is applied inside the chamber to initiate drying. Inert gas, typically nitrogen, may be introduced beneath the screen to improve moisture removal. The vibratory motion redistributes the particles during drying to promote uniform drying and reduce agglomeration. Once the process is complete, the dried solids are discharged through a sealed outlet.Material options
