IKA RV10 Digital Rotary Evaporator

Overview

The IKA RV10 Digital Rotary Evaporator is an engineered solution for efficient, reproducible solvent removal and concentration in research, quality control, and pilot-scale purification workflows. Based on the classic Couette-flow principle—where sample rotation under reduced pressure enhances surface area exposure and thermal transfer—the RV10 Digital delivers precise control over evaporation kinetics without compromising process integrity. Designed for compatibility with both aqueous and organic solvent systems, it integrates a vertically oriented glass assembly, a universal heating bath capable of water or oil operation, and a high-efficiency condensation system. Its robust mechanical architecture, combined with intelligent safety logic and digital interface capabilities, positions it as a laboratory-grade instrument meeting international expectations for reliability, traceability, and operational safety—particularly in regulated environments where procedural consistency is critical.

Key Features

• Motorized lift mechanism with automatic elevation upon power interruption—prevents thermal degradation of samples during unexpected outages
• Adjustable descent endpoint (0–60 mm), enabling precise positioning of the evaporating flask relative to the heating bath
• Dual digital display showing real-time rotation speed (20–280 rpm, continuously adjustable) and bath temperature (RT–180 °C)
• Three-section coolant-coated condenser with total active cooling surface area ≥1600 cm²—optimized for high-condensation efficiency across volatile and semi-volatile solvents
• Programmable timer function supporting repeatable, unattended operation; ideal for standardized extraction or concentration protocols
• Soft-start motor control (ramp-up to 100 rpm) minimizes splash risk and ensures stable film formation on flask walls
• Independent safety temperature circuit (adjustable range: 50–190 °C), decoupled from main setpoint for fail-safe thermal management
• PTFE-sealed stainless-steel spring gasket ensuring long-term vacuum integrity and chemical resistance
• Ergonomic bath handle and front-left control panel placement—designed to reduce operator fatigue and prevent steam contact during routine handling
• IR interface for bidirectional communication between heating bath and drive unit; RS232 port enables integration with Labworldsoft software

Sample Compatibility & Compliance

The RV10 Digital accommodates standard 3 L round-bottom flasks and is compatible with common joint sizes (e.g., ISO 29/32, 24/40). Its vertical condenser configuration supports efficient recovery of low-boiling solvents (e.g., diethyl ether, acetone, dichloromethane) as well as higher-boiling media (e.g., ethyl acetate, toluene, DMSO) when paired with appropriate vacuum control. The system meets general laboratory safety requirements per IEC 61010-1 and complies with CE marking directives. While not certified for Class I Div 1 hazardous locations, its dry-run protection, thermal cutoffs, and sealed electrical compartments align with GLP-aligned lab practices. Optional silanized or PTFE-coated glassware is available to minimize sample adhesion and facilitate cleaning—critical for residue-sensitive applications such as pharmaceutical intermediate isolation or natural product purification.

Software & Data Management

Equipped with RS232 serial output and IR-based internal communication, the RV10 Digital interfaces seamlessly with IKA’s Labworldsoft software suite (freely provided for trial and licensed use). This platform supports remote parameter setting, time-stamped event logging, multi-step gradient programming (e.g., ramped temperature + variable rotation speed), and automated distillation sequences. Audit trails generated via Labworldsoft are structured to support 21 CFR Part 11 readiness—when deployed with validated user access controls and electronic signature modules. All temperature and rotation data are timestamped and exportable in CSV format for integration into LIMS or ELN systems. Firmware updates are delivered through official IKA channels and maintain backward compatibility with existing hardware configurations.

Applications

• Solvent removal following solid-phase extraction (SPE) or liquid–liquid partitioning in environmental and food testing labs
• Concentration of peptide solutions and labile biomolecules prior to HPLC or MS analysis
• Recovery and recycling of reaction solvents in synthetic organic chemistry workflows
• Preparative purification of thermally sensitive compounds under controlled vacuum–temperature profiles
• Removal of residual solvents from polymer solutions and nanomaterial dispersions
• Standardized evaporation protocols compliant with ASTM D129, ISO 3675, or USP

FAQ

Does the RV10 Digital support both water and oil heating baths?
Yes—the integrated 4 L universal bath accepts either water or silicone oil, with independent temperature calibration available for each medium.
What vacuum level is required to achieve optimal condensation efficiency?
A stable base pressure ≤2 mbar is recommended for full utilization of the 1600 cm² condenser surface; performance scales inversely with vapor pressure of the target solvent.
Is the heating bath removable for standalone use?
Yes—the bath operates independently with full temperature control and safety cutoff functionality, making it suitable for non-evaporation applications such as controlled heating or digestion.
How does the “intermittent rotation” feature benefit powder drying?
By alternating forward/reverse motion at programmable intervals (0–60 s), the system prevents cake formation and promotes uniform heat distribution across particulate samples.
Can Labworldsoft be used to synchronize multiple RV10 units?
No—Labworldsoft controls one RV10 Digital per connected COM port; networked multi-instrument coordination requires third-party SCADA or custom API integration.
