Customer Questions & Answers
-
Question:
What is the primary purpose of the Cole-Parmer Transportable Dewar Flask, 2 L?
Answer: The primary purpose of the Cole-Parmer Transportable Dewar Flask, 2 L, is to safely store and transport cryogenic liquids such as liquid nitrogen or helium. This flask is designed with high-efficiency insulation to maintain extremely low temperatures while minimizing evaporation. Its portability makes it ideal for laboratory settings, fieldwork, or industrial applications where cryogenic liquids are required. For example, labs conducting experiments involving cryopreservation or material testing can rely on this flask to keep their samples reliably chilled during transport or storage. -
Question:
What materials are used in the construction of the Cole-Parmer Dewar flask?
Answer: The Cole-Parmer Transportable Dewar Flask is constructed from lightweight yet durable materials designed specifically for cryogenic applications. It features an outer layer made of aluminum that provides structural integrity and is coated to resist external factors. The inner vessel is typically made of glass or another specialized material that ensures optimal thermal insulation. This combination helps maintain the contents at low temperatures while minimizing heat transfer from the environment. These materials are crucial for maintaining consistent performance and ensuring the safety of the stored cryogens. -
Question:
How does the insulation of the Cole-Parmer Dewar Flask work?
Answer: The insulation of the Cole-Parmer Dewar Flask employs a vacuum layer between the inner and outer walls. This vacuum effectively prevents heat transfer, as there are no air molecules to conduct heat through. Additionally, the flask is often designed with a reflective coating that further reduces heat absorption. This advanced thermal insulation system allows the flask to maintain the low temperature of cryogenic liquids over extended periods. For instance, research laboratories can use this flask during field experiments without worrying about rapid temperature loss. -
Question:
Can the Cole-Parmer Dewar Flask be used for hazardous materials?
Answer: The Cole-Parmer Transportable Dewar Flask is suitable for storing cryogenic liquids such as liquid nitrogen and helium, which are not hazardous in themselves. However, care must be taken when using it with any materials deemed hazardous, as the flask does not protect against chemical reactivity or provide secondary containment for spills. Always consult relevant safety guidelines specific to the materials you're working with. This flask can be advantageous in settings where cryogenic materials are used in experiments that involve hazardous reagents, provided all necessary precautions are taken. -
Question:
What is the capacity of the Cole-Parmer Dewar Flask, and how does it compare to other sizes?
Answer: The Cole-Parmer Transportable Dewar Flask has a capacity of 2 liters, making it suitable for small to medium applications involving cryogenic liquids. Compared to other sizes, such as 1-liter or 5-liter options, the 2-liter flask strikes a balance between portability and storage capacity. This makes it an optimal choice for laboratories or mobile research settings where researchers require a manageable volume without sacrificing the ability to store enough material for their experiments. For example, it is ideal for smaller labs that need to transport liquid nitrogen for sample preservation. -
Question:
Is the Cole-Parmer Dewar Flask suitable for long-term storage?
Answer: While the Cole-Parmer Transportable Dewar Flask is efficient for short to medium-term storage of cryogenic liquids, it is not explicitly designed for long-term storage. The insulation will minimize evaporation, but over time, some quantity of liquid may be lost due to sublimation. For long-term storage, dedicated cryogenic storage tanks are recommended. This flask is perfect for scenarios where temporary storage is needed, such as transporting samples across research centers, but supplemental measures may be necessary for prolonged preservation. -
Question:
How does one maintain and clean the Cole-Parmer Dewar Flask?
Answer: Maintaining the Cole-Parmer Transportable Dewar Flask involves regular inspection for damages and ensuring proper sealing. Cleaning should be done with non-abrasive materials and suitable solvents to avoid damaging the internal surfaces. It’s important to allow the flask to warm to room temperature before cleaning to avoid thermal shock. Regular maintenance ensures the flask remains efficient in insulation and longevity. For example, routine checks after each use can help identify any wear or tear, ensuring that it continues to perform optimally for future applications. -
Question:
Can the Cole-Parmer Dewar Flask be used for transporting biological samples?
Answer: Yes, the Cole-Parmer Transportable Dewar Flask is well-suited for transporting biological samples that require cryogenic preservation, such as cells, tissues, or embryos. Its efficient insulation ensures that the samples remain at low temperatures during transit, which is crucial for maintaining viability. Researchers and biobanks often rely on this flask when shipping biological materials between facilities or for experimental purposes. It’s particularly valuable in sectors like biomedical research, where temperature control is critical for sample integrity. -
Question:
Where can I buy the Cole-Parmer Transportable Dewar Flask, 2 L?
