With a temperature resistance of up to 400C and complete compatibility with acids, alkalis, and solvents, this funnel ensures safe and consistent performance even under demanding laboratory conditions. Its autoclavable design guarantees sterilization flexibility and repeated hygienic usage for critical procedures.

Ease of Use and Maintenance

The smooth, conical surface allows for easy cleaning and efficient flow during filtration or transfer processes, while the short stem provides controlled and accurate pouring. Each unit is individually packaged to maintain cleanliness and quality until use, making it a reliable and maintenance-friendly choice for laboratory professionals.

FAQ's of Glass Funnel:

Q: How can the glass funnel be safely sterilized for repeated laboratory use?

A: This glass funnel is designed for easy sterilization by autoclave or dry heat methods. Simply clean the funnel, place it into the autoclave or a suitable dry heat oven, and process according to standard sterilization protocols to ensure it is safe for reuse.

Q: What types of chemicals is this funnel suitable for?

A: The funnel is resistant to acids, alkalis, solvents, and a wide range of laboratory chemicals due to its borosilicate glass construction, making it suitable for most common laboratory applications.

Q: When should I choose a short-stem glass funnel for laboratory work?

A: A short-stem glass funnel is ideal when you need faster filtration, better control when pouring into wide-mouthed containers, or when working with viscous liquids that benefit from a reduced stem length.

Q: Where can this funnel be used within laboratory settings?

A: This funnel is suitable for use in research laboratories, educational institutions, industrial labs, and quality control environments-anywhere standard laboratory glassware is utilized for filtration or liquid transfer tasks.

Q: What is the process for cleaning the funnel after each use?

A: After use, rinse the funnel with the appropriate solvent to remove chemical residues, then wash with mild laboratory detergent and water. For complete sterilization, follow with autoclaving or dry heat as required by lab protocols.

Q: What are the benefits of using borosilicate glass in this funnel?

A: Borosilicate glass provides excellent thermal and chemical resistance, reduces the risk of breakage from sudden temperature changes, and ensures compatibility with a wide range of reagents-making the funnel reliable and durable for frequent laboratory use.
