The LyoQuest laboratory freeze dryers are designed to be a multipurpose unit in the research and development field.

It is a small freeze dryer, more robust and compact than most but in spite of its small size has an unbeatable capacity. A state-of-the-art control system and a range of specially designed accessories make the LyoQuest a benchmark in its category.

The unit’s design offers the best performance in the least possible space; an extremely compact unit for freeze-drying products either in flasks, vials, ampoules or bulk. The base unit is constructed of an epoxy coated steel frame including a refrigeration system and condenser.

The stainless steel condenser can be found inside the equipment. A wide range of accessories can be connected to the condenser, allowing the unit to be flexible by being able to accommodate every individual application perfectly. The special design allows freezing the samples within the same equipment.

The equipment includes a PLC controlled unit with digital display and touch screen for the continuous monitoring of the process. It also provides fully automatic functioning, with the possibility of manual actuation.

The unit is manufactured with a standard configuration and an RS232 interface for connection to a PC via suitable monitoring Lyologger software.

Designed thinking on basic research

• Unit suitable for laboratories: compact and easy to install.
• Technical reliability and excellent performance: 8.7 kg condenser capacity.
• Flexible to use; option for adapter manifolds; option for connection of different types of chambers.
• Robustness: solidly designed laboratory equipment. On a functional level cooling management ensures optimum performance. Easy to clean. Chamber in stainless steel.
• Reliable operation: control system fully re-engineered with new options.
• Flexible use: with a touch screen user interface.
• Possibility to save the work carried out and to export data to other platforms (Excel) with the LyoLogger data acquisition software.
• Double stage vacuum pump with gas ballast and safety valve to isolate the pump from the system, so avoiding oil back streaming. An exhaust filter is included in the pump.
• Refrigerating system. Cascade system. Coil type condenser. The system includes two hermetic compressors with cascade mounting with suitable safety devices. Refrigerating fluids are CFC free.
• Control unit with digital display and friendly user touch screen.

The LyoQuest laboratory freeze dryer comes in 2 configurations:

• LyoQuest -55, with a final condenser temperature of -55 ºC.
• LyoQuest -85, with a final condenser temperature of -85 ºC, allowing a higher freeze drying speed and much more suitable for working with biological samples or products with very low eutectic or collapse points.
