Baron Blakeslee Cleaning Stations are designed for sample preparation applications in a variety of industries including Aerospace, Medical, Oxygen Service, Space, etc. The Cleaning Station provides a means for safe, efficient use of solvents in sample preparations for particulate analysis (Millipore® testing) and nonvolatile residue. Cleaning Stations are also beneficial in applications for flushing of tubing or other assemblies during a final cleaning process step. Cleaning Stations are available for use with solvents like pure fluorinated hydrocarbons, Honeywell Solstice® PF, and isopropyl alcohol.
The Cleaning Station is designed to flow clean, filtered fluorinated solvent onto parts for cleanliness verification operations, manually processed in a basin. Clean fluorinated solvent distillate flows into a clean storage tank, which is filtered. Dirty fluorinated solvent is collected in a storage tank / still equipped with a heater for distillation. All tanks are insulated, and cooled with refrigerant coils to minimize Fluorinated solvent evaporation. During a cleaning cycle, distilled, filtered fluorinated solvent flows from a manual spray wand, and the effluent of dirty fluorinated solvent is collected in the dirty solvent storage tank. When the foot switch controlling the spray wand is depressed, a solenoid valve opens in the drain line from the cleaning basin to the dirty storage tank to minimize evaporation of dirty solvent prior to distillation. Submerged cooling coils (evaporator coils of the on-board refrigeration system) are provided in both the clean & dirty fluorinated solvent tanks. The cooling coils operate continuously to minimize evaporation from both tanks, and to control cavitation of the filtration pump in the clean tank. Only during the distillation cycle do the cooling coils in the dirty tank cease to operate. When the dirty tank is full, a distillation cycle may be initiated. Distilled fluorinated solvent flows to a gravity type water separator, and flows to the clean fluorinated solvent storage tank.
