MASCARINI STILLS FOR LABORATORY USE

OPERATING PRINCIPLE
The feed water (1) enters the plant after being pre-heated in counter-flow by the distillate in the exchanger (2). Then it passes through the evaporation column tube side and is maintained at a constant regulated level. The electrical heating element (3) provides the energy to bring the water to the boiling point. The pure steam produced is aspirated by the compressor (4) and compressed outside the condenser tubes (5) where it condenses in distilled water and releases its latent heat. The distilled water is recovered in the hydrostatic column (6) and conveyed by pump (7) into the exchanger (2) where it releases its sensible heat and exits under pressure (8). The concentrate is conveyed directly to the drain (10).
The incondensable gases which are released in the hydrostatic column are sent to the discharge (11).

CONTROL SYSTEM
The Control panel is provided with a PLC and operator interface terminal. Even for laboratory stills the operations are completely automatic.
Laboratory stills are available in different versions with operation performed completely automatically or alternatively semi-automatically with start according to a weekly program and stop according to the storage tank level control.

DOCUMENTATION
 The Documentation Package supplied by STILMAS for its Plants is conceived and organized to be in compliance with the following requirements:
- To provide documented evidence of the Project Life-cycle, since the design phase up to the final Site Acceptance Test runs
- To collect all the necessary information as needed to consistently feed and Support the Validation Activity and related Support Systems (i.e. Design, Installation, Operational & Performance Qualification, Computer System Validation, Instruments Calibration,etc.); to provide to the plant user all necessary information as needed to implement a written and consistent set of internal documentation such as Operating & Maintenance S.O.P.s. Preventive Maintenace Program, Periodical Instruments Calibration Program, etc.
VALIDATION
 With regard to the Validation Activity, STILMAS is able to provide a fully comprehensive Validation Service Package, including Validation Prtocol Preparation, Site Tests execution and Validation Reports organization. The Validation Activity is performed by a dedicated Validation Team, strongly referenced in the Pharmaceutical Validation Area, which operates in strict coordination with the Project Team.
