Ningbo Scientz SCIENTZ-18ND/C Standard Manifold Freeze Dryer with Heated Shelf

Overview

The Ningbo Scientz SCIENTZ-18ND/C is a benchtop manifold freeze dryer engineered for precision, reproducibility, and operational flexibility in academic, governmental, and industrial R&D laboratories. It employs primary drying via sublimation under deep vacuum—solid-phase solvent removal without liquid-phase transition—preserving structural integrity, biological activity, and chemical conformation of thermolabile samples such as proteins, vaccines, nucleic acids, microbial cultures, and botanical extracts. The system integrates a heated shelf with PID-controlled 36 V silicone rubber heating elements, enabling controlled secondary drying and process optimization for lyophilization protocol development. Its design complies with fundamental principles outlined in ISO 22057 (freeze-drying terminology), USP (sterile processing), and supports GLP/GMP-aligned documentation workflows when paired with validated software modules.

Key Features

• Heated shelf with precise PID temperature control (range: ambient to +60 °C), eliminating thermal overshoot and ensuring stable ramp profiles for optimized drying kinetics.
• High-efficiency refrigeration system featuring Embraco (Brazil) compressors—providing rapid cooldown to ≤−56 °C (empty cold trap); optional −80 °C dual-stage cascade configuration available for low-eutectic formulations.
• 7-inch full-color capacitive touchscreen interface with industrial-grade embedded OS; real-time display of cold trap temperature, chamber pressure, shelf temperature, and vacuum status.
• Transparent one-piece polycarbonate drying chamber—chemically resistant, optically clear, and structurally robust—enabling visual monitoring of sublimation progress and ice formation dynamics.
• Eight-port stainless steel manifold with standard 24/29 or 29/32 O-ring ports; compatible with internationally standardized lyophilization flasks (e.g., Kimble, Wheaton), including wide-mouth vials and scintillation vials.
• Intelligent vacuum management: programmable vacuum pump start delay (activated only after cold trap reaches setpoint), integrated oil mist filter option, and automatic differential pressure valve to prevent backstreaming.
• Onboard data logging: automatic storage of complete freeze-drying cycles (time-stamped temperature/pressure profiles), exportable via USB to PC for analysis in Excel or third-party scientific software.

Sample Compatibility & Compliance

The SCIENTZ-18ND/C accommodates diverse sample formats—including bulk slurries, suspensions, and individual vials—without requiring pre-freezing in the chamber. Its 0.18 m² effective drying area and 6 kg/24 h condensation capacity support small-batch R&D throughput typical of university labs, QC departments, and early-stage bioprocess development. The system meets essential safety and performance benchmarks for Class II laboratory equipment per IEC 61010-1. While not certified for GMP manufacturing, its architecture supports audit-ready operation: traceable parameter logging, user-access-level controls, and configurable alarm thresholds (e.g., ambient temperature exceedance, vacuum failure). Optional eutectic point detection module enables empirical determination of optimal primary drying temperature—critical for formulation-specific cycle design aligned with FDA Q5C guidance.

Software & Data Management

Data acquisition is handled by an onboard ARM-based controller with ≥16 GB internal flash memory. All critical parameters—cold trap temperature, shelf temperature, chamber pressure, and elapsed time—are sampled at 1-second intervals and archived per cycle. Export is supported via USB 2.0 to FAT32-formatted drives; exported CSV files contain column headers compliant with ASTM E2500-21 (data format standards for pharmaceutical systems). Optional PC-based upper-computer software provides graphical overlay of multiple cycles, deviation analysis against reference curves, and PDF report generation with digital signature fields—facilitating adherence to 21 CFR Part 11 requirements when deployed with appropriate IT validation protocols.

Applications

This freeze dryer serves cross-disciplinary research domains requiring structural preservation: molecular biology (lyophilized plasmid DNA, CRISPR ribonucleoproteins), virology (inactivated virus stocks), pharmacology (small-molecule APIs, peptide conjugates), food science (enzyme powders, probiotic cultures), environmental analysis (soil microbiome samples, sediment extracts), and materials science (porous MOFs, aerogel precursors). Its manifold configuration is especially suited for comparative studies across formulations, stability testing under varied shelf temperatures, and pilot-scale parameter scouting prior to tray dryer scale-up.

FAQ

What is the maximum batch size this system can handle in manifold mode?

The unit supports up to eight standard 500 mL flasks simultaneously, with total condensable load limited to 6 kg over 24 hours—ideal for parallel small-volume experiments.

Can the shelf temperature be programmed independently from the drying cycle?

Yes—shelf heating is fully decoupled and programmable via multi-step ramp-soak profiles, enabling secondary drying optimization and residual moisture reduction.

Is the vacuum system compatible with corrosive solvents like TFA or acetic acid?

Standard configuration uses oil-lubricated rotary vane pumps; for aggressive solvents, we recommend optional oil mist filtration and chemically resistant pump variants (e.g., Edwards nXDS).

Does the system support remote monitoring or network integration?

Native Ethernet or Wi-Fi connectivity is not included; however, USB-exported datasets integrate seamlessly with LabArchives, Benchling, or custom LIMS via API-ready CSV ingestion.

What maintenance intervals are recommended for long-term reliability?

Compressor oil inspection every 12 months; cold trap cleaning after every 10–15 batches; vacuum pump oil replacement per manufacturer schedule (typically every 500 operating hours).
