Product description

The BK-FD20/30 Series pilot scale freeze dryers are designed for precise lyophilization processes in biotechnology, molecular diagnostics, and biomanufacturing research. These units include the standard models BK-FD20S and BK-FD30S as well as stoppering models BK-FD20T and BK-FD30T, offering flexibility for various laboratory freezing and drying protocols.

Key technical features include:

  • Cold trap minimum temperature: -70°C, essential for efficient ice capture during freeze drying cycles
  • Tray temperature range: adjustable from -50°C to +70°C, allowing controlled sublimation and drying
  • Vacuum level: below 0.1 mBar, ensuring optimal moisture removal
  • Cold trap capacity: 13.5 liters
  • Water capture capacity: 6.5 kg per 24 hours, suitable for intensive bioprocessing applications
  • Product volume: 4.5 L for BK-FD20 models and 7 L for BK-FD30 models, accommodating different batch sizes

Additional system specifications:

  • Cold trap dimensions: 240 mm diameter by 300 mm height
  • Lyophilization chamber size: 470 × 485 × 420 mm
  • Tray size: 305 × 405 × 17 mm, heated by silicone oil for uniform temperature distribution
  • User interface: LCD touchscreen with historical data logging for up to one month
  • Data export: USB port enables transfer of process data for quality control and documentation
  • Vacuum pump: Included, delivering 22 m³/h essential for maintaining stable vacuum during lyophilization

These freeze dryers integrate pre-freezing and drying in a single chamber, improving throughput and sample integrity. Their advanced vacuum system and precise temperature control make them widely adopted in synthetic biology research, bioprocessing workflows, and molecular cloning workflows requiring reliable moisture removal and sterile stoppering options.

The BK-FD20/30 Series is critical for live-cell imaging sample preparation, molecular diagnostics, and biopharmaceutical production pipelines where consistent lyophilization performance ensures product stability and activity.

For users requiring varying capacities and stoppering functions, consult model BK-FD20S pricing and options.

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?

Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
