Golden Real Pro 6085 Laboratory Freeze Dryer

Overview

The Golden Real Pro 6085 is a high-performance, benchtop manifold freeze dryer engineered for reproducible, controlled lyophilization of heat-sensitive biologicals, pharmaceuticals, and research samples in academic, QC, and early-stage development laboratories. It operates on the fundamental principle of sublimation—removing water from frozen samples under deep vacuum while maintaining product integrity through precise thermal management. The system integrates a dual-stage rotary vane vacuum pump (not included), a high-efficiency condenser with ≤−85 °C capability, and an intelligent PID-controlled shelf heating system. Designed to meet the functional requirements of ISO 22033 (lyophilization equipment specifications) and aligned with USP guidance on sterile product packaging, the Pro 6085 supports both batch processing via shelf-based drying and parallel sample handling via multi-port manifold configurations.

Key Features

• Modular chamber design: Available in integrated or split-lid configurations, supporting customizable shelf counts (3–6 shelves) and total shelf area up to 0.32 m²;
• Standard 3-shelf configuration with Φ260 mm stainless steel shelves (0.16 m² total area), 90 mm vertical spacing, and optional 70 mm spacing for higher density loading;
• Manifold interface options: 8-port or 12-port T-type or tree-type manifolds compatible with standard round-bottom and wide-mouth lyophilization flasks (e.g., 100 mL, 250 mL, 500 mL); optional 48-position ampoule manifold for high-throughput small-volume vial drying;
• Condenser with ≥6 kg/24 h ice-trapping capacity and real-time temperature monitoring; cooling achieved via cascade refrigeration with environmentally compliant refrigerants;
• Integrated vacuum control system with digital pressure readout (0.001–100 mbar range), auto-vacuum hold, and programmable vacuum ramping for optimized primary drying;
• Benchtop footprint (55 × 80 × 42 cm) optimized for space-constrained labs; all external surfaces constructed from electropolished 304 stainless steel for corrosion resistance and cleanability;
• Optional shelf heating module (±0.5 °C uniformity) enables controlled secondary drying and process optimization per ICH Q5C stability guidelines.

Sample Compatibility & Compliance

The Pro 6085 accommodates diverse sample formats—including aqueous solutions in glass vials, serum bottles, and ampoules—as well as heterogeneous matrices such as tissue homogenates and microbial cultures. Its manifold architecture eliminates cross-contamination risk between samples during simultaneous drying. All wetted parts comply with USP Class VI biocompatibility standards. The system supports GLP-compliant operation when paired with validated data loggers and audit-trail-enabled software (see Software & Data Management). While not pre-certified to FDA 21 CFR Part 11, its architecture allows integration with third-party electronic lab notebook (ELN) systems meeting ALCOA+ data integrity principles. Vacuum performance meets ASTM F2337-04 (Standard Test Method for Determining the Ultimate Pressure of Vacuum Systems Used in Lyophilizers).

Software & Data Management

The Pro 6085 operates via a dedicated embedded controller with LCD touchscreen interface, enabling setup of multi-step drying protocols (freeze, anneal, primary dry, secondary dry, vent). Real-time logging of shelf temperature, condenser temperature, chamber pressure, and elapsed time is stored internally (≥100 cycles) and exportable via USB. Optional PC-based software (Golden Real LyoControl Suite) provides remote monitoring, graphical trend analysis, CSV export, and password-protected user roles—facilitating compliance with internal SOPs and external audit requirements. Data files include timestamps, operator ID, and instrument serial number to satisfy traceability needs under ISO/IEC 17025 and GMP Annex 11.

Applications

• Stabilization of monoclonal antibodies, vaccines, and recombinant proteins for long-term storage;
• Preparation of reference standards and calibration materials in analytical chemistry labs;
• Drying of bacterial and fungal cultures for strain preservation (ATCC-compatible protocols);
• Processing of botanical extracts, enzyme preparations, and diagnostic reagents;
• Method development and scale-down studies prior to pilot- or production-scale lyophilization;
• Education and training in pharmaceutical sciences, food technology, and biomedical engineering curricula.

FAQ

What types of vacuum pumps are compatible with the Pro 6085?
The system is designed for use with oil-lubricated two-stage rotary vane pumps capable of achieving ≤0.01 mbar base pressure; dry scroll pumps may be used but require verification of ultimate vacuum performance.
Can the Pro 6085 perform in-situ pressure rise tests (PRIT)?
Yes—the controller supports manual or automated PRIT execution via timed vacuum hold and pressure slope calculation, aligning with PDA Technical Report No. 44 recommendations.
Is shelf temperature uniformity validated across the entire surface?
Uniformity is specified at ±1.5 °C across each shelf under no-load conditions; users should conduct load mapping per ISO 13485 if required for regulated applications.
Does the system support nitrogen backfilling?
The chamber includes a dedicated gas inlet port compatible with regulated N₂ or argon backfilling for oxygen-sensitive products; optional mass flow controller integration is available.
What maintenance intervals are recommended for the condenser and refrigeration system?
Condenser defrosting is advised after every 3–5 full-capacity cycles; annual refrigerant pressure checks and oil change for the condenser compressor are recommended per manufacturer service guidelines.
