Product description

Semiindustrial freeze dryers BK-FD50/100 with -80ºC cold trap, adjustable shelves, and vacuum pump for biotech and molecular diagnostics.

The Semiindustrial BK-FD50/100 Series freeze dryers are designed for advanced lyophilization workflows in biotechnology and molecular diagnostics. Key technical features include:

  • Model variants: Standard (BK-FD50S, BK-FD100S) and with stoppering (BK-FD50T, BK-FD100T)
  • Cold trap temperature: Minimum of -80ºC, ensuring efficient water vapor capture essential in biopharmaceutical production and gene editing sample preservation
  • Shelf temperature range: Adjustable from -50ºC to +70ºC, accommodating sensitive prefreezing and drying protocols critical in molecular cloning workflows
  • Vacuum level: <0.1 mBar, enabling controlled sublimation during freeze drying, widely adopted in synthetic biology research
  • Cold trap capacity: 18 L (BK-FD50 versions) and 35 L (BK-FD100 versions), supporting high-throughput bioprocessing
  • Water capture capacity: 8 kg/24h for BK-FD50, 15 kg/24h for BK-FD100, facilitating extensive lyophilization runs
  • Total liquid capacity: 8 L (BK-FD50x) and 16 L (BK-FD100x), suitable for batch biomanufacturing applications
  • Shelf configuration: 4+1 shelves heated by silicone oil, providing precise thermal control during drying phases
  • User interface: Touchscreen LCD with one-month historical data logging and USB export for process documentation and compliance in molecular diagnostics
  • Vacuum pump specifications: Includes vacuum pumps rated at 29 m³/h (BK-FD50) and 54 m³/h (BK-FD100), ensuring consistent vacuum conditions

These freeze dryers are essential in biotechnology fields such as synthetic biology, molecular diagnostics, and bioprocessing, offering reliable freeze drying with stoppering capability and integrated prefreezing. Their design supports high-volume lyophilization for biopharmaceutical production pipelines, live-cell sample preparation, and preservation tasks critical to clinical diagnostics and biomedical engineering research.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
