Labconco Fast-Freeze® flasks

The Fast-Freeze® Flasks are precision-engineered glass vessels designed for freeze-drying (lyophilization) applications under vacuum.

Each complete flask set includes the flask top, bottom, and filter paper, providing a ready-to-use solution for efficient sample processing.

Constructed from high-quality borosilicate glass, these flasks ensure superior chemical resistance, thermal durability, and mechanical strength, making them ideal for both aqueous and organic sample lyophilization.

Available in clear or amber glass, the Fast-Freeze® series accommodates light-sensitive and standard samples alike, with sizes ranging from 120 mL to 2000 mL.

Key Features

• Complete Set: Includes flask top, bottom, and pre-fitted filter paper.
• Durable Construction: Made from borosilicate glass for high resistance to thermal shock and chemical corrosion.
• Clear and Amber Options: Amber flasks protect light-sensitive materials; clear glass allows visual monitoring of the process.
• Vacuum-Compatible: Designed for safe and stable performance under freeze-drying vacuum conditions.
• Versatile Volumes: Wide range of capacities (120 mL to 2000 mL) for flexible sample processing.
• Standard 3/4" Flask Top Adapter: Compatible with most freeze-drying systems.
• Precision Fit: Secure neck design ensures tight sealing during lyophilization.

Ordering Information

Flask Top Adapter Diameter: ¾ inch

Applications

• Freeze-drying (lyophilization) of biological, pharmaceutical, and chemical samples.
• Storage and preservation of proteins, peptides, enzymes, and DNA/RNA extracts.
• Vacuum drying of aqueous and solvent-based formulations.
• Light-sensitive sample handling (amber versions).
• Quality control, R&D, and analytical laboratories.

Advantages

• Ready-to-use, pre-assembled design saves preparation time.
• High structural integrity minimizes risk of breakage under vacuum.
• Amber glass options safeguard photosensitive samples.
• Uniform wall thickness ensures consistent freezing and drying.
• Compatible with major laboratory freeze-drying systems.

The Fast-Freeze® Complete Flasks provide an efficient and reliable solution for laboratory freeze-drying and sample preservation workflows.

Each flask combines durability, vacuum compatibility, and convenience, with a pre-fitted filter and precision-engineered borosilicate glass body for consistent results.

Available in clear and amber glass across a wide capacity range, Fast-Freeze® flasks are ideal for biological, pharmaceutical, and chemical laboratories requiring reproducible lyophilization performance and sample integrity.
