Absorbances of acetone extracts from lake phytoplankton collected on glass‐fiber filters, ground and extracted 2 hr, were 6–18% greater than from phytoplankton collected on membrane filters and processed identically. Use of glass‐fiber filters cut filtering time by a factor of 10 and material cost by a factor of 4 or more.
