What is the primary function of a freeze dryer?

A freeze dryer, or lyophilizer, removes water from perishable materials by freezing them and then reducing the surrounding pressure to allow the frozen water to sublimate directly from the solid phase to the gas phase.

What kind of vacuum pump is typically required?

Freeze dryers commonly require a robust vacuum pump, often a rotary vane pump, capable of achieving and maintaining the low pressures necessary for sublimation.

Are these units suitable for sterile applications?

While not inherently sterile, these units can be operated in controlled environments. For sterile applications, specific aseptic techniques and potentially additional sterile components would be required.

What maintenance is typically involved with a freeze dryer?

Routine maintenance commonly includes cleaning the condenser, checking and changing vacuum pump oil, inspecting seals, and calibrating temperature and vacuum sensors.

Can this equipment handle different sample types?

Yes, with appropriate trays and vials, freeze dryers are versatile and can process a wide range of samples, from bulk solutions to individual vials of sensitive materials.

This listing is for an SP VirTis AdVantage Pro Freeze Dryer The unit is in full working condition and ready for immediate use This listing is for two units with specific configurations. Both units are direct-from-bench and were sourced from a biotech facility. Unit 1: Full System The unit is in full working condition and ready for immediate use. This Unit is supplied with: Bambi Air Compressor (Model: 35-20-240) Welch Vacuum Pump (Model: 3042-00) Integrated Digital Control System with Touchscreen Internal Product Shelving (2 Trays) Original Manuals and Operating Guides Unit 2: Main Console and Pump This unit is suitable for facilities with an existing air supply or for use as a secondary system. This Unit is supplied with: Welch Vacuum Pump (Model: 3042-00) Integrated Digital Control System with Touchscreen Note: This unit does not include an external compressor or internal trays. A precision benchtop lyophilisation system designed for sophisticated research and development applications. Known for precise control over shelf temperature and vacuum levels, it supports efficient lab workflows for proteins, organic tissues, and high-value chemical samples. Compact and user-friendly design. Transparency Report and Technical Audit: - Source Pedigree: Biotech / Research Facility - Condition: Direct-from-Bench (Decontaminated/Original) - Power-On Test: Verified; Digital display active, touchscreen responsive, and internal cooling/vacuum sequence initiation confirmed on both units. - Integrity: 100% Original Parts (Non-Refurbished) Software and Media Disclosure: As a Direct-from-Lab asset, any original software media or accessories found with the units are included as a courtesy. Licensing Notice: We do not provide, transfer, or guarantee software licenses or keys. The buyer is responsible for all software licensing, registration, and workstation compatibility via the manufacturer. Notice for Procurement: These units are sold As-Is. While we verify the power-on status, component sequence, and physical integrity, we do not perform analytical validation or full-cycle lyophilisation testing. Ideal for labs with in-house technical expertise or existing service agreements. Sustainability Impact: By choosing Direct Reuse, your facility avoids the carbon footprint of new manufacturing and prevents specialized materials from entering waste streams. Direct-to-Lab reuse is the most carbon-efficient way to equip a modern laboratory.

Типичные сведения для этой категории оборудования. Всегда уточняйте детали у продавца.

Preserving biological samples such as proteins, enzymes, and cell cultures for long-term storage.
Drying pharmaceutical ingredients and formulations to improve stability and shelf life.
Processing food samples for analytical testing or product development.
Preparing chemical samples, including sensitive organic compounds, to remove solvents.
Developing new freeze-drying protocols in research and development laboratories.

Typical capacity: Benchtop units of this class typically feature shelf areas ranging from 0.1 to 0.5 square metres, accommodating several litres of ice capacity.
Power supply: Commonly requires a standard single-phase electrical supply, typically 230V, 50Hz for UK operation, with a dedicated circuit.
Temperature range: Shelf temperatures typically range from -55°C to +60°C, with condenser temperatures often reaching -85°C or colder.
Vacuum level: Units of this type commonly achieve vacuum levels down to 10-150 mTorr (0.013-0.2 mbar) for efficient sublimation.
Footprint: Benchtop models are designed for laboratory use, typically having a compact footprint suitable for standard lab benches.
Control system: Modern units commonly feature integrated digital control systems with touchscreen interfaces for precise parameter management.

A freeze dryer, or lyophilizer, removes water from perishable materials by freezing them and then reducing the surrounding pressure to allow the frozen water to sublimate directly from the solid phase to the gas phase.

Freeze dryers are valued for their ability to preserve heat-sensitive materials whilst extending shelf life in pharmaceutical, biotech and laboratory settings. When buying used equipment, buyers typically prioritise chamber condition, vacuum pump performance and calibration history. Industry sentiment suggests these machines offer reliable operation when properly maintained, though they require careful attention to temperature uniformity and moisture removal efficiency. Reputable brands tend to hold value, and thorough pre-purchase inspection of seals and control systems is considered essential for long-term performance and cost-effectiveness.
