Goldstar Instruments Pro 9085 Freeze Dryer

Overview

The Goldstar Instruments Pro 9085 Freeze Dryer is a pilot-scale, manifold-compatible lyophilization system engineered for high-throughput, multi-user laboratory environments. It employs primary drying via sublimation under controlled low-pressure conditions—typically maintained between 0.001 and 1000 mbar—while secondary drying removes residual bound water through gentle shelf heating. Its hybrid architecture integrates a manifold port array for vial-based freeze-drying with three independently controllable heated shelves (325 × 500 mm), enabling simultaneous processing of diverse sample formats—including serum bottles, flasks, and open trays—without cross-contamination. The system’s core thermal management relies on an external coil condenser operating at ≤−85 °C, coated with PTFE to resist aggressive solvents (e.g., acetone, ethanol, acetonitrile), ensuring long-term integrity during organic solvent lyophilization. Designed for reproducibility in shared-core facilities, the Pro 9085 delivers consistent shelf temperature uniformity of ±1 °C across all three plates—a critical requirement for method transfer and regulatory validation.

Key Features

• Triple-heated shelf configuration (325 × 500 mm per shelf) with independent PID control and real-time monitoring
• External PTFE-coated condenser with 9 kg/24 h ice capture capacity and 12 kg maximum ice load tolerance
• Ultra-low ultimate vacuum performance: ≤0.01 mbar (1 Pa), achieved via corrosion-resistant dual-stage vacuum pump with integrated anti-oil-backflow valve
• Frost-resistant thermal barrier insulation minimizes ambient heat ingress and condenser icing during extended cycles
• One-touch programmable venting with inert gas (N₂ or air) purge capability for oxygen-sensitive samples
• Hot-gas automatic defrost cycle reduces downtime between batches without manual intervention
• Manifold ports compatible with standard KF-25 and NW25 flanges for direct connection to glassware or stoppering devices
• Intuitive touchscreen interface with preloaded SOP templates, user-level access control, and cycle parameter locking

Sample Compatibility & Compliance

The Pro 9085 accommodates aqueous and organic solvent-based formulations—including buffers containing methanol, DMSO, or ethyl acetate—without degradation of condenser performance or vacuum integrity. Its PTFE-coated condenser surface and chemically resistant vacuum path meet ASTM F2337-22 requirements for solvent compatibility in pharmaceutical lyophilization. The system supports Good Laboratory Practice (GLP) workflows through configurable data logging (temperature, pressure, time, shelf power), with optional 21 CFR Part 11-compliant software enabling electronic signatures, audit trails, and role-based permissions. All mechanical components comply with ISO 13485:2016 design controls for medical device manufacturing support, and electrical safety conforms to IEC 61010-1.

Software & Data Management

The embedded LyoS operating system provides full-cycle automation with up to 99 customizable protocols, each supporting multi-step ramp/soak profiles for shelf temperature and vacuum setpoints. Real-time graphs display condenser temperature, chamber pressure, product temperature (via optional thermocouple input), and accumulated ice mass. Raw data export is available in CSV and PDF formats; optional cloud-connected firmware enables remote monitoring and centralized fleet management. When paired with the Goldstar DataVault module, the system generates tamper-evident audit logs compliant with FDA 21 CFR Part 11 Subpart B, including user actions, parameter changes, and alarm events—with immutable timestamps and digital signature verification.

Applications

• Pharmaceutical R&D: Stabilization of monoclonal antibodies, vaccines, and peptide APIs under GMP-aligned process development conditions
• Biotechnology: Lyophilization of cell lysates, enzyme preparations, and CRISPR-Cas reagents requiring solvent tolerance
• Academic Core Facilities: High-turnover processing of heterogeneous sample sets—from microbial cultures to plant extracts—across multiple research groups
• Food Science: Preservation of probiotics, enzymes, and flavor compounds while retaining structural integrity and bioactivity
• Material Science: Preparation of porous scaffolds and aerogels via controlled ice nucleation and sublimation kinetics

FAQ

What types of solvents can be safely processed on the Pro 9085?
The PTFE-coated condenser and chemically resistant vacuum train enable reliable handling of common organic solvents including ethanol, methanol, acetone, and ethyl acetate—provided vapor pressure and concentration remain within ASHRAE Class 3A limits.
Is shelf temperature calibration traceable to NIST standards?
Yes—each unit ships with a factory calibration certificate referencing NIST-traceable RTD probes; field recalibration kits and third-party verification services are available upon request.
Can the system operate unattended overnight?
Absolutely—the Pro 9085 includes comprehensive safety interlocks (condenser over-temp, vacuum loss, power failure recovery) and automatic cycle termination with inert gas backfill, certified for continuous 72-hour operation under ISO 14644-1 Class 7 cleanroom conditions.
Does it support automated stoppering integration?
Yes—manifold ports accept standard stoppering manifolds (e.g., Edwards, SP Scientific); optional electro-pneumatic valve control enables synchronized vacuum break and stopper insertion via external PLC interface.
What maintenance intervals are recommended for the vacuum pump?
Oil change every 2000 operating hours; full pump inspection and seal replacement every 6000 hours—logbook templates and predictive maintenance alerts are built into the LyoS software.
