Product Overview
The Beifan Digital Rotary Evaporator is designed for controlled solvent recovery, sample concentration, and chemical synthesis. As an established rotary evaporator manufacturer, we replace manual analog adjustments with a microprocessor-driven PID controller. This unit ensures identical, repeatable batch processing for laboratories, pharmaceutical R&D, and chemical manufacturing.
Operational Standardizations:
• Temperature Fluctuations: Eliminated via real-time PID feedback control.
• Process Tracking: Dual LCD/LED screens display both target and actual parameters simultaneously.
• Maintenance Overhead: Heavy-duty drive mechanisms reduce mechanical wear during continuous operation.
Key Technical Advantages
PID Microprocessor Control System The digital controller manages rotation speed and bath temperature to remove operator-to-operator variability between shifts.
Visual Monitoring: Continuous dual-screen readouts prevent batch parameters from drifting undetected.
Thermal Stability: Critical for managing heat-sensitive active pharmaceutical ingredients (APIs) or natural extracts.
Step-less Speed Regulation The motor drive provides a continuous range of 20 to 280 RPM, establishing a uniform liquid film over the inner surface of the flask.
Evaporation Efficiency: Maximizes the surface area for heat transfer, preventing localized bumping or overheating.
Vibration Dampening: The structural stabilizing mechanism counteracts dynamic imbalances at high RPMs, even when processing high-viscosity media.
Dual-Media Thermal Management (±0.2°C) The heating bath adapts to different chemical protocols by supporting both water and oil heating media.
Safety Interlocks: Built-in dry-boil protection and thermal cut-off circuits automatically disconnect power if limits are exceeded.
Dual-Component Vacuum Sealing The interface relies on a combined PTFE and Viton double-sealing ring assembly.
Solvent Compatibility: The sealing materials resist breakdown from aggressive organic solvents, preventing sample contamination.
Pressure Maintenance: Holds a continuous deep vacuum to lower solvent boiling points for low-temperature distillations.

FAQ
Q: What is the primary operational advantage of the digital model over standard analog units?
A: The digital model uses a PID controller to lock temperature tolerances to ±0.2°C and provides exact RPM readouts. Analog units rely on manual knobs, which introduces operator error and prevents standardized batch replication.
Q: Can we review your compliance certifications before placing an order?
A: Yes. Copies of our CE certificates and ISO 9001 compliance documentation are available upon request for your import evaluation. Please contact our sales team directly to receive the PDF copies.
Q: What are your standard lead times and Minimum Order Quantities (MOQ)?
A: Our standard configuration MOQ is 1 unit, with dispatch within 3–5 business days. Custom branding or OEM configurations typically require a 15–25 day production lead time depending on component adjustments.
Q: How does the system handle highly corrosive solvents?
A: All fluid-contact and vapor-path components are restricted to GG-17 borosilicate glass and PTFE/Viton seals. This material selection provides universal chemical resistance against standard acids, bases, and organic compounds.
Q: How are fragile glassware components protected during international shipping?
A: All glassware components are nested in custom-cut foam inserts and shipped inside drop-tested, heavy-duty export wooden crates to prevent transit damage during sea or air freight.
