Product description

The Labconco FreeZone Fast-Freeze Flask is a specialized lyophilization flask assembly engineered for integration with Labconco FreeZone freeze-drying systems. Constructed from durable borosilicate glass, the flask withstands extreme low temperatures and sustained vacuum conditions essential in freeze-drying and sublimation processes commonly used in molecular diagnostics and bioprocessing workflows.

Key features include:

  • Chemical-resistant silicone rubber top designed to maintain a clean, vacuum-tight seal, ensuring reproducible performance across multiple cycles.
  • Available in 300 mL and 600 mL volumes, supporting scalability in biomanufacturing and synthetic biology research requiring precise sample handling.
  • Optimized dimensions (300 mL: 4 x 4 x 8 in, 2 lbs; 600 mL: 5 x 5 x 7 in, 3 lbs) facilitate compatibility with standard freeze-drying chambers.
  • Free from defects such as chips and cracks, promoting contamination-free lyophilization and consistent sample integrity critical for biotechnology and molecular cloning workflows.

This flask assembly serves as a reliable intermediary vessel between biological samples and the lyophilizer, making it a critical accessory for researchers focused on live-cell imaging preparation, fluorescence analysis, and biomedical engineering applications requiring freeze-dried sample preservation. Its compatibility with Labconco FreeZone systems ensures seamless integration into established freeze-drying protocols widely adopted in biopharmaceutical production pipelines.

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.
