Thermo Scientific Savant RVT5105-230 Refrigerated Cold Trap

Overview

The Thermo Scientific Savant RVT5105-230 Refrigerated Cold Trap is an engineered vacuum accessory designed for high-efficiency solvent capture during rotary evaporation, lyophilization, and other vacuum-based sample preparation workflows. Operating on a closed-cycle vapor-compression refrigeration system, it achieves stable low-temperature condensation surfaces—down to −105 °C—without reliance on cryogenic consumables such as dry ice or liquid nitrogen. Its thermodynamic architecture is optimized for consistent thermal load management under continuous vacuum conditions (typically 0.1–10 mbar), ensuring reliable condensate retention across volatile organic solvents, halogenated compounds, and polar aprotic media. Unlike passive cold traps, the Savant series integrates active temperature regulation with real-time monitoring, enabling precise alignment between condensation temperature and solvent vapor pressure curves—critical for minimizing pump oil contamination and preserving vacuum integrity in analytical and preparative systems.

Key Features

• Three selectable operating temperature configurations: −5 °C, −50 °C, and −105 °C—each calibrated for targeted solvent classes based on boiling point and vapor pressure characteristics
• CFC-free and HCFC-free refrigerant formulation compliant with Montreal Protocol requirements and modern environmental stewardship protocols
• Rapid cooldown performance: reaches −105 °C from ambient in ≤45 minutes under standard lab conditions (23 °C, 50% RH)
• Digital LED temperature display (integrated on RVT4104 model variants) with ±1 °C accuracy and 0.1 °C resolution for process traceability
• Robust stainless-steel cold finger assembly with enhanced surface area geometry for uniform frost deposition and minimized channeling effects
• Standardized GCF400 borosilicate glass condensing flask (400 mL capacity) and FC400 threaded cap with integrated O-ring seal for leak-tight vacuum coupling

Sample Compatibility & Compliance

The Savant RVT series supports broad compatibility with common laboratory solvents used in pharmaceutical synthesis, natural product isolation, and polymer processing. The −5 °C configuration effectively traps high-boiling-point solvents including dimethyl sulfoxide (DMSO), N,N-dimethylformamide (DMF), ethylene glycol, and glycerol. The −50 °C and −105 °C variants are validated for chlorinated solvents (chloroform, dichloromethane), ethers (diethyl ether, THF), esters (ethyl acetate), and low-molecular-weight hydrocarbons (pentane, hexane). All units are manufactured in accordance with ISO 9001-certified production processes and meet UL/CSA electrical safety standards. No component materials contact process vapors outside the certified borosilicate glass condenser assembly—ensuring compliance with USP , FDA 21 CFR Part 11 data integrity expectations (when paired with compatible digital loggers), and GLP audit requirements for documented temperature control.

Software & Data Management

While the base RVT5105-230 operates as a standalone analog-controlled unit, optional integration with Thermo Fisher’s SmartLink™ Vacuum Control System enables remote monitoring, setpoint scheduling, and event-triggered logging via Ethernet or USB. Temperature history is recorded at user-defined intervals (1–60 sec) with timestamped CSV export capability. Audit trails include operator ID, parameter changes, alarm events (e.g., high-temperature deviation >±3 °C), and power cycle timestamps—supporting 21 CFR Part 11 compliance when deployed with validated electronic signature modules and role-based access controls. Firmware updates are delivered through Thermo Fisher’s secure Instrument Manager portal, with version rollback and checksum verification built into the update protocol.

Applications

• Rotary evaporation of heat-sensitive compounds where solvent removal must occur below decomposition thresholds
• Lyophilization pre-freezing and primary drying stages requiring controlled condensate capture without mechanical vibration transfer
• High-vacuum distillation setups involving multi-solvent mixtures with disparate volatility profiles
• Environmental sample concentration workflows per EPA Method 525.3 and ASTM D7066 for semi-volatile organic analysis
• QC/QA laboratories performing residual solvent testing (ICH Q3C guidelines) with gravimetric or GC-MS validation
• Academic research labs conducting solvent recycling studies under ISO 14001-aligned waste minimization protocols

FAQ

What is the recommended maintenance interval for the RVT5105-230 compressor system?

Thermo Fisher recommends biannual inspection of refrigerant charge integrity, condenser coil cleanliness, and electrical connection torque—documented per ISO/IEC 17025 calibration management procedures.
Can the RVT5105-230 be operated continuously for >72 hours?

Yes. The unit is rated for continuous duty under nominal vacuum load (≤5 mbar) and ambient temperatures ≤30 °C, provided adequate ventilation clearance (≥15 cm on all sides) is maintained.
Is the GCF400 flask autoclavable?

No. Borosilicate glass components are not designed for steam sterilization; cleaning is performed using acetone rinse followed by deionized water and nitrogen purge.
Does the −105 °C model require special electrical infrastructure?

The RVT5105-230 (230 V, 50/60 Hz) draws ≤12 A peak current and requires a dedicated grounded circuit with GFCI protection—no three-phase or UPS support is mandated.
How does the cold trap interface with third-party vacuum pumps?

It features a standardized 24/40 ground-glass joint and optional VCR or KF25 adapters; vacuum line compatibility is verified per ISO 2861-1 dimensional tolerances and leak-rate specifications (<1×10⁻⁷ mbar·L/s He).
