Digital Laboratory Rotary Evaporator

The Beifan Digital Laboratory Rotary Evaporator is a benchmark industrial and lab-grade instrument designed for precise solvent evaporation, concentration, purification, and recovery. By integrating a microprocessor-controlled heating bath with a vacuum-sealed rotating system, it effectively lowers solvent boiling points to allow rapid, gentle evaporation at reduced temperatures.

This advanced process prevents thermal degradation of heat-sensitive compounds and optimizes workflow efficiency across chemical, pharmaceutical, herbal extraction, and biotechnological industries.

Microprocessor PID Control System: The integrated digital control panel provides real-time monitoring and micro-adjustments of rotation speed and bath temperature. This continuous feedback loop maintains stable processing conditions, ensuring exact repeatability across multiple batches.

Advanced Film Evaporation Technology: Continuous rotation of the evaporation flask creates a uniform, ultra-thin liquid film across the entire inner surface. This maximizes the effective surface area for heat transfer, preventing localized overheating (bumping) and accelerating vapor formation.

Vacuum-Assisted Low-Temperature Distillation: Operating under reduced system pressure lowers the boiling point of target solvents. This allows for low-temperature distillation, preserving the molecular integrity of volatile compounds, natural extracts, and organic intermediates.

Dual-Medium Heavy-Duty Heating Bath: The insulated, double-walled heating bath accommodates water (up to 99°C) or oil (up to 180°C). High-caliber heating elements deliver uniform thermal distribution to minimize temperature fluctuations during extended runs.

Variable Hydrodynamic Speed Control: Adjustable rotation speeds from 10 to 280 rpm allow operators to match flask dynamics to specific liquid properties, effectively managing high-viscosity samples or minimizing foam generation.

Corrosion-Resistant Borosilicate Glass 3.3 Flow Path: The complete vapor-condenser-receiver circuit is constructed from premium Borosilicate Glass 3.3 (ISO 3585 compliant). This heavy-duty glass withstands aggressive organic solvents, thermal shocks, and acids without leaching, while its high transparency allows direct visual monitoring of the process.

As a dedicated manufacturer, Beifan supports global distributors, laboratories, and pharmaceutical factories with robust supply chain security:

Factory-Direct Pricing & Scalable Discounts: Direct sourcing from our manufacturing facility eliminates middleman markups, providing highly competitive, tiered pricing for bulk wholesale orders.

Global Electrical & Plug Compatibility: Units are custom-configured to match destination-specific grids, including 110V/60Hz or 220V/50Hz with US, EU, UK, or AU plug standards.

Rigorous Pre-Shipment Quality Validation: Every rotary evaporator undergoes strict factory testing prior to crating. This includes vacuum integrity checks (leak-rate testing), rotation stability calibration, and a multi-hour heating bath stress test.

Secure International Packaging: Glassware and heavy bases are packed separately in export-standard, shock-proof wooden cases to ensure safe global transit and zero-damage arrival.

Immediate Component Availability: We maintain dedicated inventory reserves of high-wear parts (PTFE vacuum seals, vapor tubes, and glassware components) to ensure rapid replacement and minimize equipment downtime for end-users.

Pharmaceutical Development: Concentration of active pharmaceutical ingredients (APIs) and solvent removal post-chromatography.

Chemical Synthesis: Routine solvent recovery, purification of reaction products, and organic workups.

Botanical & Natural Product Extraction: Low-temperature concentration of essential oils, cannabis/hemp compounds, and thermal-sensitive botanical extracts.
