Compatible with multiple flask volumes—600, 750, 900, 1200, and 2000 ml—it integrates seamlessly with Labconco freeze dryer systems. This flask top fits securely on glass or stainless steel adapters of 0.5 in or 0.75 in diameter, enabling direct attachment to valve ports on Labconco manifolds and drying chambers.

Key features include:

  • Durable silicone rubber material ensuring chemical resistance and flexibility under freeze drying conditions
  • Compatibility with a broad range of flask bottoms for versatile laboratory use
  • Essential component in bioprocessing workflows, molecular diagnostics, and synthetic biology requiring contamination-free lyophilization
  • Complements specialized filter papers to maintain sterile environments within freeze drying assemblies

Widely used in biotechnology labs, this Fast-Freeze Flask Top supports critical freeze drying steps in molecular cloning, pharmaceutical biomanufacturing, and cell imaging sample preparation. It ensures airtight sealing and efficient sublimation, making it an indispensable accessory for researchers focused on freeze drying in biopharmaceutical production pipelines and live-cell imaging sample preservation.

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.
