Ningbo Scientz SCIENTZ-18N/D Benchtop Freeze Dryer with Manifold and Stoppering Capability

Overview

The Ningbo Scientz SCIENTZ-18N/D is a pilot-scale benchtop freeze dryer engineered for reproducible, high-fidelity lyophilization of thermolabile biological, pharmaceutical, and material science samples. It operates on the principle of sublimation under deep vacuum—where ice transitions directly from solid to vapor without passing through the liquid phase—preserving structural integrity, bioactivity, and chemical conformation of sensitive analytes. Designed for laboratories requiring batch flexibility and multi-vial processing, the SCIENTZ-18N/D integrates a transparent polycarbonate drying chamber, manifold ports with stoppering capability, and a robust single-stage or optionally dual-stage cascade refrigeration system. Its compact footprint (600 × 450 × 720 mm main unit + 440 mm cold trap extension) enables deployment in standard fume hood bays or shared instrumentation rooms while delivering 0.12 m² effective lyophilization area and up to 4 kg condensate capacity per cycle—making it suitable for method development, small-batch GMP-aligned process validation, and academic research workflows.

Key Features

• 7-inch full-color capacitive touchscreen interface with industrial-grade embedded OS for real-time monitoring and intuitive operation
• Imported high-efficiency hermetic compressor system delivering stable cold trap temperatures ≤−56 °C (optional −80 °C cascade configuration available)
• Polycarbonate drying chamber: one-piece molded, corrosion-resistant, optically transparent, and vacuum-tight for full-process visual observation
• Manifold configuration with eight standard 24/29-thread ports compatible with internationally standardized lyophilization flasks and stopper-seal vials
• Intelligent vacuum management: programmable vacuum pump start delay based on cold trap temperature setpoint to extend pump service life
• Automatic data logging: all critical parameters—including shelf temperature (if equipped), cold trap temperature, chamber pressure, and elapsed time—are timestamped and stored internally
• USB export functionality for raw freeze-drying curves; compatible with PC-based analysis software for trend evaluation and protocol archiving
• Optional accessories include vacuum oil mist filter, automatic pressure-equalization valve (to prevent oil backstreaming), and eutectic point measurement module

Sample Compatibility & Compliance

The SCIENTZ-18N/D accommodates diverse sample formats including aqueous solutions, suspensions, gels, and tissue homogenates across life sciences, food safety, environmental, and materials research domains. It supports lyophilization of proteins, enzymes, vaccines, nucleic acids, microbial cultures, plant extracts, nanomaterial dispersions, and soil/sludge matrices without agglomeration or denaturation. While not certified for cGMP production, its architecture aligns with GLP-compliant documentation requirements: audit-trail-capable data storage, user-accessible calibration logs, and configurable alarm thresholds (e.g., ambient temperature exceedance). The system meets CE electromagnetic compatibility (EMC) directives and conforms to IEC 61010-1 for laboratory electrical safety. For regulated environments, optional features—including password-protected user roles and electronic signature support—facilitate alignment with FDA 21 CFR Part 11 readiness when integrated into validated workflows.

Software & Data Management

The embedded control system records ≥10,000 data points per run at user-defined intervals (1–60 s). All datasets are saved in CSV format with metadata headers (date, operator ID, protocol name, version). USB flash drive export enables offline review in Excel or third-party analytics platforms (e.g., OriginLab, MATLAB). Freeze-drying profiles can be imported/exported between instruments for method transfer consistency. The interface supports up to 20 pre-programmed protocols, each with customizable ramp rates, hold durations, and pressure modulation steps. Real-time graphing displays concurrent trends for vacuum level, cold trap temperature, and (if shelf-heating option installed) plate temperature—enabling immediate deviation detection during primary drying.

Applications

• Academic & government research: stabilization of viral vectors, bacterial strains, and fungal spores for long-term archiving
• Pharmaceutical R&D: formulation screening of lyophilized monoclonal antibodies, peptide therapeutics, and mRNA-LNP complexes
• Food science: preparation of reference standards for pesticide residue analysis in fruits, vegetables, and meat matrices
• Environmental testing: moisture removal from soil, sediment, and wastewater sludge prior to elemental or organic contaminant quantification
• Materials engineering: drying of sol-gel precursors and colloidal nanoparticle suspensions to prevent aggregation and preserve surface area
• Clinical diagnostics: processing of serum, plasma, and CSF specimens for biomarker stability studies

FAQ

What is the maximum batch volume this freeze dryer can handle?

The SCIENTZ-18N/D supports up to 4 L of total solution volume across the manifold flasks, assuming typical 10–15% solids content and optimized freezing geometry.

Is shelf heating available as a factory option?

Yes—electrically heated shelves (±0.5 °C uniformity, range: −40 to +60 °C) can be specified at time of order to enable controlled secondary drying and improve residual moisture reduction.

Does the system support remote monitoring via Ethernet or Wi-Fi?

Standard configuration includes only local touchscreen control and USB data export; Ethernet connectivity and cloud-based telemetry require custom firmware integration and are available under OEM agreement.

Can the cold trap be defrosted automatically?

Yes—the built-in electric defrost function activates after cycle completion, reducing manual intervention and shortening turnaround time between batches.

What vacuum pump models are recommended for optimal performance?

Scientz validates compatibility with Edwards RV8, Agilent TW-10, and Leybold D30B rotary vane pumps; oil-free scroll pumps may be used but require verification of ultimate vacuum attainment (<5 Pa) under load.
