Overview
FD-12 series laboratory freeze dryers (lyophilizers) are designed for freeze-drying laboratory samples and small-batch production. The units combine stainless-steel condenser and adjustable shelves, a transparent drying chamber for observation, and microprocessor control with graphical display for monitoring and logging drying curves and key parameters.

Characteristics

• Microprocessor control with 7" touch LCD showing drying curve, vacuum, condenser temperature, run time and ambient temperature
• Pre-freezing function for sample preparation
• High refrigeration capacity and low noise using DANFOSS (SECOP) compressors with CFC-FREE refrigerant
• 304 stainless-steel condenser, racks and shelves for corrosion resistance; shelves height-adjustable for flexible loading
• Transparent drying chamber for visual process monitoring
• Compact, floor-standing design for laboratory environments
• Condenser options: -55°C (standard), -80°C or -110°C dual-cascade for solvent-containing samples (optional)
• Electric heating defrost for quick turnaround between runs (optional)
• Nitrogen inflation valve available for inerting and transfer operations
• Multiple chamber configurations (normal, manifold, top-press, T-type) to fit vial, flask and ampoule workflows
• CE / ISO 9001 / ISO 13485 / ISO 14001 certified

Common samples
Typical applications include biological samples, vials, food samples, small-batch bulk bioproducts and other materials suitable for lyophilization; used in R&D, QC and small production labs.
