500ml Buchner Funnel Vacuum Filtration Kit - Lab Filtering Flask Set,Used in Laboratory (7 Combination)

This vacuum filtering kit is equipped with complete spare parts including a filtering flask, a hand-held vacuum pump, 80mm buchner funnel,100 pcs filter paper, a silicone tube, stopper set and a cleaning brush in one set, so it is ready to use when unpacked without purchasing additional components. This device can perfectly adapt to various scenarios, such as, sample pretreatment and teaching labs, providing efficient and stable filtration experiences for scientific researchers, lab technicians, teachers and students, as well as testers. Buchner Funnel Vacuum Filtering Kit Includes: ✅ Filtering Flask: It is made of high borosilicate glass and marked with clear scale, making it convenient for the real-time observation of filter liquor volume; and its standard ground joint guarantees a tight seal with the funnel, avoiding leakage risks. ✅ 80mm Buchner Funnel: It is made of high-quality ceramics materials, allowing high temperature resistance. The bottom of the funnel features evenly distributed perforations, allowing the filter paper to be smoothly supported and the sample liquid to be evenly distributed, thus improving filtration efficiency. ✅ Hand-Operating Vacuum-Pump with Pressure Gauge: Its anti-slip handle offers comfortable one-handed operation, and no power source required offers high portability; its built-in pressure-gauge can display the vacuum degree in real time, allowing the filtration pressure to be accurately controlled, thus avoiding the damage of filter paper and the backflow of filter liquor. ✅ Sealing Accessories Kit: The kit includes 9 Count Filter Adapter Cones and upgraded high-elasticity silicone vacuum tube, providing strong stability, aging resistance and no extraneous odor, and creating a vacuum system without leakage. ✅ Supporting Consumables: Filter paper compatible with the 80 mm funnel and a brush are provided, making the device ready for experimentation immediately, so you are not required to prepare additional consumables.
