DURAN® Filter Funnel Head, with PP Funnel, 30 mL
One of the most important separation methods in the laboratory environment is filtration, which is used to separate or clean different media. For this working method, filters are required which are selected according to the application with regard to size and porosity. The filter funnel head consisting of the filter head, sealing ring, glass filter disk and funnel can be dismantled into its individual parts and each individual component can be replaced or varied in order to adapt the filter to the application. The three unit sizes combined with four filter plates of different porosities each create 12 different filter options.
Features and Benefits:

• Interchangeable filter disks allow a specific selection of the filter
• Available in three filter diameters, each of which are available in four different porosities
• In order to allow a simple and safe removal of the filtered material, the filter plate must be inserted between two FKM seals.
• Long filter disk service life, as disks are not damaged when the filtrand is scraped off
• Easy cleaning of both sides is possible
• Cost-effective as components and disks can be ordered seperately as required
• Easy-to-read scale with graduation marks to estimate the content
• Fired-on, highly durable white print

Application: Separation of the filtrate for its further processing, Qualitative inorganic analysis and preparative chemistry, Filtration at reduced pressure, Filtering, The PP funnel and two FKM seals are included in the scope of delivery of the filter attachment. Suitable slit slieve discs as carrier for membrane and paper filters are available separately.
