IKA RV 8 V Starter Solution Rotary Evaporator

Overview

The IKA RV 8 V Starter Solution is a compact, entry-level rotary evaporator engineered for reliable solvent removal, concentration, and gentle sample recovery in R&D, quality control, and pilot-scale production environments. Designed according to fundamental principles of vacuum distillation—where reduced pressure lowers the boiling point of solvents while controlled rotation increases surface area and heat transfer efficiency—the RV 8 V delivers consistent performance across chemical synthesis, pharmaceutical formulation, natural product isolation, and biotechnology workflows. Its robust all-metal frame, 24 V low-voltage DC motor drive, and IP20-rated enclosure ensure operational safety and long-term stability under routine laboratory conditions. As part of IKA’s established RV platform, it maintains full mechanical and dimensional compatibility with the broader RV 10 series glassware ecosystem, enabling seamless scalability without revalidation of glass joint interfaces or condenser alignment.

Key Features

• 4 L heating bath with extended temperature range up to 180 °C, supporting high-boiling-point solvents including DMSO, NMP, and ethylene glycol
• Digital LED display for both rotational speed (5–300 rpm) and bath temperature, enabling real-time parameter monitoring and reproducible method execution
• Vertically oriented triple-layer condenser providing 1500 cm² effective cooling surface area—optimized for high-efficiency vapor condensation across wide volatility ranges
• Manually operated lift mechanism with 120 mm travel stroke, adjustable endpoint positioning, and tactile end-stop feedback for repeatable flask immersion depth
• Dual mechanical locking system: primary evaporation flask clamp plus secondary safety lock with integrated red visual indicator when disengaged
• Ergonomic single-hand operation design—including angled motor mount adjustment, dedicated bottle-release knob, and insulated carry handle on the heating bath
• Compliance with IEC/EN 60529 (IP20), EN 61010-1 (safety requirements for electrical equipment), and RoHS directives

Sample Compatibility & Compliance

The RV 8 V accommodates standard ISO-K 29/32 and ISO-K 24/29 ground-glass joints, ensuring interoperability with IKA’s full suite of RV 10-compatible glassware—including 1 L, 2 L, and 4 L round-bottom flasks, vertical and diagonal condensers, and specialized receiving flasks. It supports aqueous, organic, and moderately corrosive solvent systems when used with appropriate PTFE-coated seals and cold traps. For regulated environments, the instrument’s analog control architecture and absence of embedded data storage align with GLP-compliant documentation practices where manual logbook entries are required. While not equipped with electronic audit trails or 21 CFR Part 11–compliant software, its stable mechanical design facilitates integration into validated processes governed by ISO 17025, USP , and ASTM E2656 (Standard Guide for Validation of Analytical Instrumentation).

Software & Data Management

The RV 8 V operates as a standalone analog-digital hybrid system with no built-in connectivity (USB/Ethernet) or proprietary software interface. All operational parameters—including setpoint values and physical adjustments—are manually configured and visually verified via front-panel displays. This architecture eliminates firmware dependencies, reduces cybersecurity exposure, and simplifies IQ/OQ documentation for GxP-regulated facilities. Users may integrate external digital vacuum controllers (e.g., IKA Vacstar or Vacuubrand VRD) and PT100 temperature probes for enhanced process logging. Calibration records for bath temperature and rotation speed should be maintained per internal SOPs, referencing traceable NIST-traceable references at defined intervals.

Applications

• Solvent removal from reaction mixtures post-synthesis in medicinal chemistry labs
• Concentration of heat-sensitive natural extracts (e.g., flavonoids, terpenes) under mild vacuum conditions
• Recovery and recycling of chlorinated and non-halogenated solvents in QC laboratories
• Preparative-scale fractionation in academic teaching labs requiring intuitive, low-maintenance instrumentation
• Stabilization of unstable intermediates through rapid low-temperature evaporation prior to lyophilization or crystallization

FAQ

What is the maximum recommended flask size for the RV 8 V?

The system is rated for use with up to 4 L round-bottom flasks, matching the bath capacity and mechanical stability envelope.
Can the RV 8 V be connected to an external vacuum pump or controller?

Yes—it features a standard 10/12 mm O.D. vacuum port compatible with diaphragm pumps, oil-sealed rotary vane pumps, and programmable vacuum controllers.
Is the heating bath filled with oil or water by default?

The bath is dry and user-filled; silicone oil (up to 180 °C) or water/glycol mixtures (for ≤100 °C applications) may be selected based on thermal stability and safety requirements.
Does the unit include a chiller or cold trap?

No—the RV 8 V Starter Solution is supplied without active cooling; users must provide an external coolant source (e.g., recirculating chiller) or dry ice/acetone cold trap depending on solvent volatility.
How often does the rotary seal require maintenance?

Under normal use with clean solvents, the PTFE-impregnated rotary seal requires inspection every 500 operating hours and replacement every 1,500–2,000 hours—or sooner if visible wear, leakage, or inconsistent rotation torque is observed.
