Flask Freeze Dryer – QualiFD™ F Series
The QualiFD™ F Series Flask Freeze Dryer is a precision freeze-drying system built for flask-based lyophilization using a hanging-bottle T-frame. Its design allows fast attachment and removal of multiple flasks during runs, enabling laboratories to process mixed sample sets efficiently without interrupting operation.
This Flask Freeze Dryer is ideal for biomedicine applications, peptide research, synthesis samples, and long-term strain preservation, where precise low-temperature performance and stable vacuum are critical.
Featuring a low-temperature cold trap capable of ≤ -85 °C, with an optional extension down to ≤ -110 °C (no-load), the QualiFD™ F Series ensures optimal moisture removal. The system supports T-shaped hanging-bottle frames, with customizable layouts to meet lab-specific requirements.
A three-way valve design allows flexible bottle management during operation, while a 7-inch industrial touchscreen records and visualizes freeze-drying curves and process data for analysis and USB export.
Applications – QualiFD™ F Series Flask Freeze Dryer
Strain and Microorganism Preservation: Freeze-dry bacteria, fungi, and microbial strains for extended storage with lower variability compared to liquid storage. The hanging-flask T-frame layout allows multiple bottles to be processed in a single run, ideal for strain libraries and routine sample banking.
Peptides and Sensitive Biomedical Samples: Gentle solvent removal at low temperature preserves peptides and other delicate biomedical materials. The low-temperature cold trap and stable vacuum minimize thermal stress while efficiently capturing vapor.
Synthetic Chemistry and Intermediate Drying: Perfect for temperature-sensitive intermediates and solutions that are challenging to dry under heat. The T-frame and three-way valve system enables vessel swapping without interrupting the drying cycle.
Multi-Vessel R&D Screening: Conduct parallel drying of different flask sizes for method development and screening. Supports conical and wide-mouth flasks to accommodate common laboratory vessels.
Standards – QualiFD™ F Series Flask Freeze Dryer
- ISO 13408-3: Guidelines for aseptic processing and lyophilization, providing requirements for process control and validation when lyophilization is used in sterile applications.
- ASTM E3250-21: Best practices for freeze dryer instrumentation, focusing on accurate temperature and pressure measurement in pharmaceutical freeze-drying workflows.
- IEC 61010-1: General safety standards for electrical laboratory equipment, ensuring safe operation in research and industrial settings.
Flask Freeze Dryer – QualiFD™ F Series Key Features
- Designed for biomedicine, peptide research, and synthesis sample freeze-drying with a hanging-bottle T-frame layout.
- Stainless steel T-frame with welded construction to minimize leak risk during multi-bottle operations.
- Optional customized internal channel routing to align with lab workflows and vessel arrangements.
- Three-way valve system allows bottles to be added or removed without interrupting the drying cycle.
- Dedicated vacuum pump ensures stable operation and consistent vacuum performance.
- 7-inch industrial touchscreen provides real-time freeze-drying curves, process data logging, and USB export.
- Nitrogen or inert gas backfill valve for controlled venting and sample protection after drying.
- Electric defrost function speeds up turnaround between runs.
- Optional compatibility with low-temperature rotary freezing instruments for integrated workflows.
Theory and Method – QualiFD™ F Series Flask Freeze Dryer
Freeze drying removes solvents from frozen samples under vacuum through sublimation instead of boiling. The process begins by freezing the sample, reducing chamber pressure, and then applying controlled heat so ice transitions directly to vapor, which is captured on the cold trap.
Lower cold-trap temperatures enhance vapor capture and maintain a stable vacuum during primary drying. Secondary drying further reduces bound moisture to achieve the desired residual levels. Monitoring process curves ensures repeatable results across runs and provides reliable documentation for lab records.
