Pilotech YC-210 Falling Film and Wiped-Film Vacuum Concentrator

Overview

The Pilotech YC-210 Falling Film and Wiped-Film Vacuum Concentrator is an engineered solution for rapid, low-thermal-stress concentration of heat-labile, high-viscosity, or foaming liquid samples under controlled vacuum conditions. Unlike conventional rotary evaporators—where batch processing subjects samples to prolonged residence time in heated vessels—the YC-210 employs a continuous-flow wiped-film evaporation principle based on Couette flow dynamics and thin-film heat transfer. Liquid feed enters the top of a vertically oriented, jacketed glass evaporator tube, where a precision-machined PTFE-coated rotor assembly rotates at adjustable speed to generate a uniform, sub-millimeter-thick film that flows downward under gravity. Simultaneous heating (via circulating thermal fluid in the jacket) and high-vacuum environment (typically 0.1–5 mbar) enable instantaneous solvent vaporization upon film formation. Total thermal exposure time is consistently ≤30 seconds—from inlet to concentrated distillate collection—minimizing degradation of thermally sensitive actives such as peptides, enzymes, natural extracts, and unstable APIs.

Key Features

• Continuous-feed architecture eliminates batch bottlenecks; supports unattended operation for multi-hour concentration cycles
• Optimized wiped-film geometry ensures uniform film thickness and high surface-area-to-volume ratio for enhanced mass and heat transfer coefficients
• High-purity borosilicate glass construction (DIN/ISO-compliant) with chemical resistance to common organic solvents, acids, and bases
• Integrated PID-controlled thermal fluid circulation system with ±0.5 °C stability across operating range (20–120 °C)
• Automated vacuum regulation via digital pressure controller and dual-stage vacuum pump (oil-free option available)
• Ergonomic, single-hand operation interface with intuitive tactile controls and real-time parameter feedback
• 72-hour pre-shipment endurance testing under full-load vacuum and thermal cycling conditions

Sample Compatibility & Compliance

The YC-210 accommodates aqueous, alcoholic, and mixed-solvent systems—including DMSO, DMF, ethyl acetate, methanol, and chlorinated solvents—with demonstrated performance across viscosities up to 5,000 cP and surface tensions down to 22 mN/m. It is routinely deployed in GLP-compliant laboratories for API intermediate purification, botanical extract concentration, and post-synthesis solvent recovery. The system meets mechanical safety requirements per ISO 13857 and electrical safety standards IEC 61010-1. Vacuum components comply with ASTM E2912 for leak integrity. While not inherently 21 CFR Part 11–certified, its data logging interface supports integration with validated LIMS or ELN platforms for audit-trail generation when paired with compliant software infrastructure.

Software & Data Management

The YC-210 operates via embedded microcontroller firmware with local parameter storage (temperature setpoint, rotation speed, vacuum target, run duration). All operational parameters are timestamped and exportable via USB-C to CSV format for traceability. Optional RS-485 Modbus RTU interface enables integration into centralized lab automation networks. No cloud connectivity or proprietary software installation is required—operation remains fully functional offline. User-accessible calibration routines allow verification of thermal fluid temperature accuracy and vacuum transducer linearity per internal SOPs.

Applications

• Rapid desolvation of peptide synthesis reaction mixtures without racemization
• Concentration of thermolabile herbal extracts (e.g., polysaccharides, flavonoids) while preserving antioxidant activity
• Solvent recovery from crystallization mother liquors in pharmaceutical manufacturing
• Dehydration of enzyme-containing fermentation broths prior to lyophilization
• Removal of residual ethyl acetate from polymer synthesis intermediates
• Simultaneous concentration and degassing of viscous food emulsions (e.g., soy lecithin solutions)

FAQ

What is the typical residence time of sample in the evaporator tube?
Residence time is consistently measured at ≤30 seconds under standard operating conditions (60 °C, 1 mbar, 100 mL/min feed rate), verified by tracer dye studies and thermal profiling.
Can the YC-210 handle foaming solutions without carryover?
Yes—the combination of controlled film shear, optimized vapor path geometry, and integrated demister section prevents entrainment, even with highly foaming surfactant systems.
Is cleaning validation supported?
All wetted parts are accessible, non-porous, and compatible with standard CIP protocols using 0.5 M NaOH or 70% ethanol; residue limits can be verified via HPLC or TOC analysis.
Does the system support GMP documentation packages?
Factory-supplied IQ/OQ protocols are available upon request; user qualification (PQ) must be performed in situ per site-specific process requirements.
What maintenance intervals are recommended?
Rotor bearing inspection every 1,000 hours; vacuum pump oil change every 500 hours (if oil-lubricated); annual recalibration of temperature and pressure sensors.
