Labconco FreeZone 6 Plus Freeze Dryer with Stoppering Tray Features
- 6-liter ice capacity collector for moderate throughput applications
- Ultra-low temperature capability down to -84°C
- Integrated stoppering tray for sealing vials under vacuum
- Three temperature-controlled shelves (-40°C to +40°C)
- Lyo-Works touchscreen with programmable methods and data logging
- Real-time monitoring of vacuum and temperature parameters
- Compact console design with built-in viewing window
- Suitable for both aqueous and low eutectic samples
- 90-day warranty included from American Instrument Exchange
Featuring a 6-liter ice-holding collector and advanced refrigeration capable of reaching temperatures as low as -84°C (-119°F), the FreeZone 6 Plus efficiently removes moisture from both aqueous and low eutectic point samples.
The integrated stoppering tray dryer allows users to freeze-dry samples and seal them under vacuum without exposure to atmospheric moisture, significantly improving sample stability and shelf life. This is especially critical for sensitive materials such as biologics, vaccines, and pharmaceuticals.
Equipped with three temperature-controlled shelves (-40°C to +40°C) and programmable protocols, the system provides precise thermal control throughout the drying cycle. The Lyo-Works operating system with touchscreen interface enables real-time monitoring of vacuum levels, collector temperature, and process parameters for consistent, repeatable results.
Its compact console design includes a front viewing window, built-in vacuum connections, and space for a vacuum pump, making it a complete and efficient freeze-drying solution for moderate sample loads.
Applications include pharmaceutical and biotech lyophilization, vaccine, protein, and biologic stabilization, serum bottle and vial processing with stoppering, environmental and analytical sample preservation, and research and academic laboratories.

FAQs – Labconco FreeZone 6 Plus Freeze Dryer with Stoppering Tray
What is the advantage of a stoppering tray freeze dryer?
A stoppering tray system allows you to dry samples and seal vials under vacuum, preventing contamination and moisture exposure. This is essential for preserving sensitive pharmaceutical and biological samples.
What types of samples can this system handle?
The system is suitable for:
- Aqueous samples
- Low eutectic point compounds (e.g., solvents like acetonitrile)
- Biological materials (proteins, enzymes, tissues)
- Pharmaceuticals and vaccines
Its low-temperature capability ensures effective processing of temperature-sensitive materials.
What is the capacity of the FreeZone 6 Plus?
This unit features a 6-liter ice collector and can remove approximately up to 4 liters of water per 24 hours, depending on configuration and temperature settings.
How does the stoppering tray improve workflow efficiency?
The stoppering tray:
- Eliminates the need to transfer samples after drying
- Allows in-place sealing under vacuum or inert gas
- Reduces contamination risk and handling time
This leads to faster workflows and improved reproducibility.
What level of control does the system provide?
The system offers:
- Programmable temperature ramping (-40°C to +40°C)
- Adjustable vacuum setpoints
- Real-time monitoring via touchscreen
- Data logging and export via USB/Ethernet
These features enable precise process optimization and repeatability.
What additional equipment is required?
A vacuum pump (typically ≥163 L/min displacement) and appropriate glassware or trays are required for operation.
Is the system suitable for high-throughput labs?
Yes. While compact, the combination of:
- Multi-shelf tray drying
- Programmable automation
- Simultaneous processing
makes it ideal for moderate to high sample throughput environments.
How does this system compare to standard manifold freeze dryers?
Compared to manifold systems, this unit offers:
- Better control of shelf temperature
- Ability to process bulk samples
- Integrated stoppering capability
- Greater reproducibility
This makes it the preferred choice for regulated or precision-driven applications.
Why choose a refurbished freeze dryer instead of new?
Refurbished units provide:
- Significant cost savings
- Verified performance through testing
- Faster availability
For many labs, refurbished equipment delivers the best balance of cost, performance, and reliability.
