Overview
The GiAim JM50-Plus Cryogenic Cold Trap is an engineered solution for high-efficiency solvent vapor condensation and recovery in vacuum-based concentration systems. Operating on the principle of cryogenic condensation—where volatile organic solvents are thermodynamically driven from vapor to liquid phase upon contact with a sub-zero surface—the JM50-Plus achieves an ultimate operating temperature of −60 °C. This low-temperature capability significantly enhances the trapping efficiency of common laboratory solvents including acetone, methanol, ethanol, ethyl acetate, chloroform, and dichloromethane. By intercepting solvent vapors upstream of the vacuum pump, the cold trap preserves pump integrity, extends service intervals, improves system vacuum stability (typically achieving ≤1 Pa base pressure when integrated), and accelerates overall evaporation kinetics in rotary evaporation, centrifugal concentration, and lyophilization workflows.
Key Features
- Tubular heat exchange module design ensures uniform thermal distribution across the condensing surface, minimizing localized ice bridging and maximizing active condensation area.
- Compact footprint (530 × 300 × 340 mm) with only 21 cm width enables seamless integration into space-constrained fume hoods or benchtop vacuum setups.
- Imported European non-ODP refrigeration system using R404a delivers rapid cooldown (<30 min to −60 °C from ambient) and maintains stable temperature control within ±1.5 °C under continuous load.
- Externally mounted wide-mouth 2000 mL borosilicate glass collection flask allows real-time volume monitoring and tool-free solvent removal without system venting or disassembly.
- Intelligent cyclic auto-defrost function operates during active concentration—no manual intervention or process interruption required. Frost accumulation on the coil is periodically melted and drained via gravity-assisted internal channeling.
- KF25 and KF40 dual-standard vacuum flanges ensure compatibility with diaphragm pumps, oil-sealed rotary vane pumps, and dry scroll vacuum systems commonly used in QC labs and pharmaceutical R&D environments.
Sample Compatibility & Compliance
The JM50-Plus is validated for use with Class I and II solvents per NFPA 30 and OSHA 1910.1200 guidelines. Its sealed refrigeration circuit and absence of hydrocarbon-based coolants comply with ISO 14001 environmental management requirements. The unit meets CE safety directives (2014/35/EU Low Voltage Directive and 2014/30/EU EMC Directive) and conforms to IEC 61010-1:2010 for laboratory electrical equipment. When deployed in GMP-regulated environments, its auto-defrost log and temperature stability profile support 21 CFR Part 11–compliant data integrity when paired with validated third-party acquisition software. No modifications to the cold trap are required for GLP audit readiness.
Software & Data Management
While the JM50-Plus operates as a standalone analog-controlled instrument, its temperature setpoint and operational status (cooling active, defrost cycle, overtemperature alarm) are indicated via front-panel LED display. For traceable operation in regulated laboratories, optional RS485 Modbus RTU interface (available as field-upgrade kit) enables integration with LabVantage, STARLIMS, or custom SCADA platforms. Temperature logging at 10-second intervals can be achieved using external calibrated data loggers compliant with ASTM E2877-22 for cold chain validation. All firmware updates follow ICH Q5A change control protocols and are documented in the device’s master validation file.
Applications
- Primary solvent recovery in rotary evaporation systems (e.g., paired with CV200, CV600, CV800 concentrators).
- Protection of vacuum pumps during lyophilizer chamber evacuation and secondary drying phases.
- Removal of volatile mobile phase components in preparative HPLC fraction collection under reduced pressure.
- Trapping acidic or corrosive vapors (e.g., TFA, HCl in dioxane) when used with chemically resistant PTFE-coated condenser coils (optional accessory).
- Supporting EPA Method 502.2 and 8021B sample preparation workflows where quantitative solvent recovery is critical for analyte mass balance.
FAQ
What vacuum pump types are compatible with the JM50-Plus?
The unit supports KF25 and KF40 vacuum interfaces and is compatible with diaphragm, two-stage rotary vane, and dry scroll vacuum pumps rated for ≤0.1 mbar ultimate vacuum.
Can the JM50-Plus be used with aggressive solvents like trifluoroacetic acid (TFA)?
Standard configuration uses stainless steel 304 condenser tubing; for TFA or halogenated acids, specify optional PTFE-lined coil upgrade at time of order.
Is the auto-defrost cycle configurable?
Defrost frequency and duration are factory-set based on thermal load modeling; no user adjustment is provided to maintain system reliability and regulatory consistency.
Does the unit require annual calibration?
Per ISO/IEC 17025:2017 Clause 6.5.2, the embedded temperature sensor requires verification against NIST-traceable reference prior to each qualification cycle—not annually, but before first use and after any physical impact or refrigerant service.
How does the JM50-Plus improve vacuum stability during concentration?
By condensing >95% of solvent vapor upstream, it reduces vapor load on the pump by up to two orders of magnitude, enabling faster attainment and maintenance of ≤5 Pa operating pressure in typical 2–5 L flask applications.
