FAQ's of FUNNELS aLONG STEM:
Q: How should I sterilize the FUNNELS - LONG STEM before reuse?
A: These funnels can be easily sterilized by autoclaving, as they are constructed from borosilicate glass and engineered to withstand temperatures up to 400C. After use, clean thoroughly and place in an autoclave for proper sterilization, ensuring safe and contaminant-free reuse.
Q: What types of chemicals are compatible with these long stem funnels?
A: The FUNNELS - LONG STEM are resistant to a wide range of chemicals, including acids, alkalis, and organic solvents. Their borosilicate glass construction offers excellent chemical compatibility, making them suitable for handling most laboratory reagents and solutions.
Q: When is it appropriate to use a long stem funnel over a standard funnel?
A: Long stem funnels are preferred when precise control over liquid transfer is required or when reaching deep into vessels is necessary. Their extended stems make them ideal for use in tall flasks, graduated cylinders, or for minimizing spillage during delicate filtration and transfer applications.
Q: Where can these funnels typically be used within laboratory settings?
A: These funnels are commonly used in chemical, biological, and analytical laboratories for transferring or filtering liquids. Their design allows application in test tubes, beakers, flasks, and other laboratory vessels, accommodating diverse procedures.
Q: What are the dimensions and capacity options available for these funnels?
A: Standard options include diameters of 50 mm, 75 mm, and 100 mm with stem lengths of at least 100 mm, and capacities commonly ranging from 250 ml to 500 ml. Custom sizes and capacities are also available to meet particular requirements in laboratory processes.
Q: How does the polished, smooth surface benefit laboratory work?
A: The polished inner surface of the funnel reduces the risk of residue sticking, ensuring complete and efficient transfer of liquids. This feature also facilitates easier cleaning and maintenance, further enhancing the funnel's utility and longevity for repeated use.
Q: What are the key benefits of choosing these funnels for laboratory processes?
A: These funnels provide chemical resistance, high temperature durability, easy cleaning, and reliable performance. Being reusable and autoclavable, they contribute to sustainable laboratory practices while maintaining precision and safety during liquid handling tasks.
