The Segewick Rafter chambers are excellent for determining counts in known volumes of sample, see: (Sedgewick Rafter - technical data). These chambers have also found use for in-vitro fertilisation studies, and various papers have been written.

The Pyser-SGI Howard Cell is used for spore counting in tomato and fruit juice, see:  (Howard Cell - technical data)
