Grade 2 filter paper is slightly more retentive and having more absorbing power than Grade 1 with a corresponding increase in filtration time. In addition to general filtrations, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials. Also used for monitoring specific contaminants in the atmosphere and in soil testing.
Grade 3 filter paper is almost double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging. The extra thickness gives increased wet strength and makes this grade highly suitable for use in Buchner funnels. The high absorbency is particularly valuable when the paper is used as a sample…
These cone shaped flasks are rigid, translucent and autoclavable. The screw cap keeps the contents of the flask contamination free and makes the flask leakproof. Threads should be disengaged before autoclaving.
