Lyophilizer (Freeze Dryer)

KEY FEATURES

• Construction & Materials
  Stainless steel chamber, chemically compatible seals/valves for solvents, easy-clean surfaces suitable for GMP labs

• Freezing / Cold-Trap Capability

  • Cold-trap (or condenser) temperature: table-top units achieve –50°C, –70°C, or –80°C or lower

  • Ice-condensation (water capture) capacity: removal of several kg of water per 24 h in the condenser

  • Refrigeration system: CFC/HCFC-free, cascade or high-efficiency compressors with good insulation

• Control Panels
  Digital/microprocessor-based temperature and vacuum control & display
  LED/LCD readouts showing cold trap temperature, vacuum curve, sample shelf temperature
  Automated sequences: auto start-up of vacuum pump when trap is cooled, interlocks, defrosting functions, alarms for maintenance (e.g., oil change)

• Vacuum / Drying Chamber Capability

  • Final vacuum level: Benchtop units reach < 10 Pa (or ~0.1 mbar) or better.

  • Vacuum pump: Often double-stage rotary vane or direct-drive, with gas ballast or oil-return protection.

  • Drying chamber: Stainless steel material, with transparent lid or bell-cap for visibility, often adjustable shelves or manifold ports for vials/flasks.
