Whatman 1950-207 Accessories: Funnel Reservoir, 70mm

The Whatman 1950-207 is a replacement reservoir designed for 3-piece Whatman filter funnel systems, allowing liquid samples to be held above the filter during gravimetric or particulate filtration. It is commonly used with glass microfiber filters for fast and efficient laboratory filtration.

This funnel reservoir provides approximately 115 mL sample capacity with a 70 mm diameter, allowing larger sample volumes to be filtered without frequent refilling.

Yes. The 1950-207 is designed specifically as a replacement reservoir for the Whatman 3-piece funnel, which typically includes a funnel base, support plate, and reservoir that clamp together for secure filtration.

The reservoir is commonly used with 70 mm diameter glass microfiber filters or compatible filter papers, supporting applications requiring fine particle retention and rapid flow rates.

This accessory is typically used for gravimetric analysis, suspended solids testing, environmental filtration, and sample preparation, where controlled filtration and easy cleaning between runs are required. The modular funnel design helps simplify filter replacement and reduce carryover.
