These UltraFlow disposable polypropylene filter funnels come with preinserted SPE filter disks and fit the J.T. Baker® SPE apparatus. Filter disks are constructed of two layers of glass fiber filter material. The top layer acts as a prefilter while the bottom layer is bound to a high carbon C-18 adsorbent. This laminar construction results in a product with a high flow rate and higher dirt holding capacity than other SPE products.
Polypropylene, disposable funnel housing has over 250mL capacity. Tests show no measurable extractable levels in the polypropylene housings.
