Description
Product Overview
The Pope Scientific 8900 Full Base Dewar Flask is engineered for precision laboratory work where reliability and safety are paramount. Constructed from high‑grade borosilicate glass, the flask offers excellent thermal resistance, allowing it to maintain low temperatures for extended periods without cracking. The 350 ml capacity is ideal for a wide range of applications, from small‑scale reagent storage to temperature‑sensitive sample preservation. A distinctive feature of this model is the integrated full base, which provides a flat, stable footprint that prevents wobbling on benchtops and reduces the risk of accidental spills. Complementing the glass body is a sturdy metal handle, forged from corrosion‑resistant stainless steel, that enables effortless lifting and repositioning even when the flask is filled with chilled liquids. The handle is ergonomically shaped to fit comfortably in the hand, reducing strain during repeated use. Dimensions of the flask measure 19.21 × 9.06 × 4.02 inches, and the unit weighs just over one pound, making it both compact and portable for busy laboratory environments. The product carries the model number 8900 and is manufactured by Pope Scientific, a trusted name in laboratory glassware known for rigorous quality control and compliance with international safety standards.
Usage
This Dewar flask excels in a variety of laboratory settings. In chemistry labs, it serves as a reliable vessel for storing temperature‑sensitive reagents, ensuring that compounds remain stable during synthesis and analysis. In biology and life‑science research, the flask is frequently used to keep cell culture media, enzyme solutions, and other biologics at low temperatures, preserving activity and viability. The full base design makes it suitable for placement on standard lab benches, fume hoods, and refrigerated workstations without the need for additional support accessories. The metal handle allows technicians to quickly transfer the flask between cold storage units, workstations, and transport carts, minimizing exposure to ambient temperatures. Because the glass is chemically inert, the flask can safely contain a broad spectrum of solvents, acids, and bases without risk of reaction or contamination. Its compact size also makes it a practical choice for field‑based research teams that require portable cooling solutions for on‑site sample collection. Whether used in academic research, industrial quality‑control labs, or teaching laboratories, the 8900 Dewar flask delivers consistent performance and ease of handling.

FAQ
Can the flask be used with cryogenic liquids?
The 8900 Dewar flask is designed for standard laboratory cooling applications and can safely hold liquids cooled to typical refrigerated temperatures. For cryogenic liquids such as liquid nitrogen, a specialized cryogenic Dewar with appropriate insulation is recommended.
Is the metal handle compatible with gloves?
Yes, the stainless‑steel handle is sized to accommodate standard laboratory gloves, allowing users to lift and move the flask without removing protective handwear.
How should the flask be cleaned after use?
Rinse the flask with distilled water to remove residues, then wash with a mild laboratory detergent. Rinse thoroughly and allow to air‑dry. Avoid abrasive scrubbers that could scratch the glass surface.
What is the warranty period for this product?
Pope Scientific offers a one‑year limited warranty covering manufacturing defects. Contact our support team for warranty claims or replacement requests.
Can the flask be autoclaved for sterilization?
The borosilicate glass can tolerate autoclave temperatures, but the metal handle may be affected by prolonged exposure to high humidity. It is advisable to remove the handle before autoclaving or use a protective cover.
