Review on πŸ” Ahlstrom 6100 2400 Qualitative Filter Diameter: Enhanced Performance and Precision by John Brazington

Revainrating 5 out of 5

Very slow flow but very efficient. For wet board.

Very slow flow but very efficient. For photographers using wet plates: I use it to filter out silver nitrate when photographing with wet collodion plates and to filter out sandrac lacquer. The paint takes several hours to run through the funnel (200ml) but comes out clean. Silver nitrate, freshly sun-bleached, acts faster and becomes clear as water.

Pros
  • Solid construction
Cons
  • No automatic
