Laboratory quality medium speed filter paper with low ash content - available in 3 sizes ( 9cm, 12.5 cm and 15
cm). Also available in slow & fastspeed. Use 'slow' paper when very high purity filtering is required and 'fast'
paper for rapid quantitative filtering (or for liquids that are
typically difficult to filter). 'Medium' speed is a good compromise
between the two and ideal for all-around use.
Box of 100 circles.
