Yarong SY-2000 Benchtop Rotary Evaporator (Standard Configuration)

Overview

The Yarong SY-2000 Benchtop Rotary Evaporator (Standard Configuration) is an engineered solution for precise, repeatable solvent removal, concentration, and crystallization in research and quality control laboratories. Operating on the principle of reduced-pressure distillation, the system rotates a sample-containing flask in a heated bath while maintaining controlled vacuum conditions—thereby lowering the boiling point of solvents and minimizing thermal degradation of heat-sensitive compounds. Its integrated design features a dual-reflux condenser with standardized ball-joint connections, ensuring high-efficiency vapor capture and condensate recovery. The SY-2000 is calibrated for operation across both aqueous and high-boiling-point organic media, supporting workflows in pharmaceutical development, environmental analysis, natural product isolation, and polymer synthesis where reproducibility and process traceability are essential.

Key Features

• Full-color LCD touchscreen interface with intuitive menu navigation and encoder-based parameter input for rotation speed, bath temperature, vacuum setpoint, and timed operation
• PID temperature control with independent calibration for water and oil bath modes—achieving ±1 °C stability in water and ±2 °C in oil at steady state
• Frequency-controlled synchronous drive delivering smooth, low-noise rotation from 10 to 200 rpm with consistent torque across the full range
• Motorized vertical lift mechanism (0–150 mm stroke) enabling precise flask positioning relative to the condenser and bath—critical for optimizing evaporation kinetics and preventing bumping
• Built-in vacuum management system featuring a solenoid valve, real-time pressure feedback, and synchronized pump control—eliminating manual venting and enabling uninterrupted vacuum-state feeding via a dedicated valve port
• Robust sealing architecture using high-elasticity PTFE gaskets compatible with aggressive solvents and temperatures up to 180 °C
• 4 L thermostatically controlled heating bath with 1500 W power output, supporting rapid thermal equilibration and stable setpoint maintenance

Sample Compatibility & Compliance

The SY-2000 accommodates standard-taper glassware ranging from 50 mL to 2000 mL, with its 2 L rotating flask and dual-reflux condenser optimized for high-yield recovery of volatile and semi-volatile fractions. All wetted surfaces—including condenser, adapter, and collection flasks—are constructed from borosilicate 3.3 glass meeting ISO 3585 specifications. The instrument’s vacuum controller (YRZK-10S) and diaphragm vacuum pump (YR-PTB) are rated for continuous duty in Class II chemical environments. While not certified to IEC 61010-1 out-of-the-box, the SY-2000’s electrical architecture complies with fundamental safety requirements for laboratory equipment. When operated within defined parameters and documented procedures, it supports GLP-aligned data integrity practices and can be integrated into GMP-relevant processes requiring temperature/vacuum logging and user-access controls.

Software & Data Management

The SY-2000 operates via embedded firmware with non-volatile memory for storing up to 10 user-defined protocols—including ramp rates, hold times, and multi-step vacuum profiles. Real-time operational data (temperature, speed, vacuum level, elapsed time) is displayed continuously and may be manually recorded. Although the standard configuration does not include USB or Ethernet connectivity, the system’s digital interface supports external data acquisition via analog voltage outputs (0–5 V) for temperature and vacuum signals—enabling integration with third-party SCADA or LIMS platforms. For audit readiness, users are advised to implement supplementary logging tools compliant with FDA 21 CFR Part 11 requirements when electronic records are required.

Applications

• Solvent recovery and concentration of active pharmaceutical ingredients (APIs) during early-stage formulation development
• Removal of chlorinated and polar solvents (e.g., DCM, acetone, methanol) from reaction mixtures in synthetic organic chemistry
• Concentration of environmental water samples prior to GC-MS or HPLC analysis per EPA Method 525.3
• Extraction and purification of plant-derived compounds (terpenes, alkaloids, flavonoids) under mild thermal conditions
• Preparative-scale dehydration of polymer solutions and colloidal suspensions
• Routine QC testing in biotechnology labs for buffer exchange and lyophilization pre-concentration steps

FAQ

What flask sizes are compatible with the SY-2000?

The system accepts standard-taper ground-glass flasks from 50 mL to 2000 mL, with optimal performance observed using 1 L and 2 L rotating flasks mounted on the included 2 L main flask assembly.
Can the SY-2000 operate under inert atmosphere?

Yes—when equipped with optional gas inlet adapters and PTFE-sealed valves, the system supports nitrogen or argon purging during evaporation to prevent oxidation of air-sensitive compounds.
Is the vacuum controller programmable for multi-stage pressure ramps?

The built-in YRZK-10S controller supports single-setpoint vacuum regulation only; multi-stage ramping requires external programmable vacuum controllers or manual intervention.
Does the unit include bath fluid?

No—water or heat-transfer oil must be supplied separately based on the target operating temperature range.
What maintenance intervals are recommended for the vacuum pump?

The YR-PTB diaphragm pump requires oil replacement every 500 hours of cumulative operation and filter inspection every 100 hours under continuous use.
