Advanced Benchtop Freeze Dryer – QualiFD™ B adv Series

An Advanced Benchtop Freeze Dryer in the QualiFD™ B adv Series is a compact Freeze Dryer Machine built for heavier daily sample-prep workloads, with automation and protection functions that support stable long-run operation.

Standard configuration includes a high-performance freeze-drying vacuum pump, intelligent control, automatic cold-trap defrost, an oil mist filter, and automatic air inlet/drain features. QualiFD™ B adv Series uses a modular platform so you can choose a configuration that fits your workflow, such as standard tray drying, vial stoppering, or manifold-assisted drying. The control system supports data visibility and routine documentation through a touchscreen interface and logged process information.

Automatic defrost is available, with electric defrost standard and hot-gas defrost noted as an option. Safety interlocks and protection logic help reduce vacuum system faults and protect the pump and compressor during continuous use.

Advanced Benchtop Freeze Dryer – QualiFD™ B adv Series Applications

  • Laboratory sample preparation for biology and biotech: Labs use a Freeze Dryer to preserve cells, enzymes, and biological specimens for longer storage while supporting later reconstitution. This series supports routine tray-based drying and higher-throughput sample handling when the workload increases.
  • Pharma and formulation work: Vial workflows benefit from the top-press configuration, where vials can be sealed after drying while still under vacuum. That supports longer storage stability and reduces moisture pickup during post-process handling.
  • Chemical synthesis and temperature-sensitive materials: Freeze drying helps remove solvent while avoiding heat-driven degradation that can happen with conventional drying. Manifold configurations also support drying in bottles or wide-mouth containers, depending on your sample format.
  • Microorganism preservation in ampoules: The ampoule tube type is described for preserving microorganisms such as bacteria and fungi, using dedicated tube interfaces. This is useful for culture collections, QC labs, and R&D teams that maintain reference strains.

  • Optional AISI 316L cold-trap material and freeze-drying protective film are listed as selectable modules

Theory and Method

Freeze drying removes water by freezing the sample, pulling vacuum, then driving sublimation so ice transitions directly to vapor. Vapor is captured by the cold trap, and stable vacuum helps maintain repeatable primary drying.

Secondary drying continues at controlled conditions to lower residual moisture to your target. Logged temperature and vacuum trends support repeatability checks across runs, which helps in R&D and QC documentation.
