Design: This filter funnel features two standard taper inner joints at both ends and a medium porosity fritted disc sealed in the middle of the main tube. The pore diameter for the fritted disc is from 10 to 20 ?m, and the O.D. of the fritted disc is 30mm.
Usage: This glassware is designed for laboratory use in filtration applications, such as separating solids from liquids, or in gas filtration. The fritted disc provides a porous surface area for the liquid or gas to pass through while retaining the solid particles or impurities.
Material: The funnel is made of high-quality borosilicate glass, which is known for its durability and resistance to thermal shock. The glass is heavy wall designed, made by hand-blowing to ensure uniform wall thickness, and annealed at 800 degrees Celsius to withstand typical laboratory thermal variations in chemistry processes like heating and cooling.
Craft: The funnel is crafted with precision and attention to detail to ensure its quality and accuracy. The fritted disc is sealed in the middle of the main tube using specialized glassblowing techniques, ensuring a secure and leak-free seal. The funnel's overall design is also optimized for ease of use and handling in laboratory settings.
Guarantee: Laboy offers a 100% 40-day money-back guarantee on all their glassware products. If the customer is not satisfied with the product, they can return it for a full refund, no questions asked.
