A Pasteur pipette or glass dropper can be used to drop the solvent onto the filter paper during the filtration process.
See this link for examples.
Any form of chromatography could be used to separate liquid ink.Thin Layer Chromatography would be the simplest method:-Put a dot of the black ink around 1/4 of the way up a piece of filter paper.Place the filter paper in a buffer solution (usually a mixture of methanol and cyclohexane), but don't submerge the dot of ink.Wait for the buffer solution to get most of the way up the filter paper via absorptionThe black ink should have separated into several different colours that have moved different distances up the filter paper.Read more: http://wiki.answers.com/What_separation_technique_would_be_used_to_separate_liquid_ink_in_black_pen#ixzz18Cf0o84yYou can suction it out.
Cut the piece of paper having the DNA into small pieces and drop it into a 1.5 mL microfuge tube. Add enough TE buffer to submerge the the piece of paper, give sufficient time for the DNA to get into the buffer. Spin the tube at 13,000 rpm for 5 minutes. collect the supernatant which has your DNA and use it Preetam,UWO
It depends what sort of solution and what sort of chromatography. Assuming it's something simple like ink you'd usually use a piece of paper or filter paper. You'd apply a spot of your analyte (the solution being analysed) at a short distance from the bottom of the paper, then put the paper in a beaker or similar container with a small amount of ethanol, water or another solvent in the bottom. Ensure that the solvent does not go above the level of the spot of analyte. The solvent will be drawn up through the paper by capillary action, and will draw the different parts of the analyte with it and deposit them at different distances from the initial spot. Stop the experiment by removing the paper from the beaker once the solvent front (the horizontal line where the highest wet part of the paper is) reaches the top of the paper.

If its a piece of paper and has holes in it then its the gasket for between the filter and the tranmission
To make a paper filter at home, you will need a piece of paper towel or coffee filter. Fold the paper in half, then in half again to create a cone shape. Trim the bottom to fit your container. Place the filter in the container and pour your liquid through it.
Paper chromotagraphy is a technique of separating a solution containing two or more soluble solids. A minute amount of the solution is first dotted on a piece on paper. The paper is then hung above a solvent (such as water or ethanol) just so that the tip of the paper is soaked in the solvent.The solvent then rises upwards and soaks the rest of the paper. This occurs because there is a force of attraction between the solvent and the paper.As the solvent rises, it carries the sample of the initial solution and separates the dissolved solids. The multiple different solids settle at different points on the paper, based on its solubility.The point at which the solvent stops rising upwards is known as the solvent front.

filtrate sand is a filtrate it stays behind
If you mix a dye with a colourless solvent (e.g. alcohol) and place a drip of it in the centre of a round piece of filter paper, the different dyes will "run" at different speeds and for different distances. You will be left with a series of concentric circles which are of different colours.

Usually, it's used to separate a precipitate from the liquid in the solution. The filter paper is folded into quarters and placed in the funnel. The solution is then poured onto the filter paper, where the liquid filters through and the precipitate stays on the filter paper. The precipitate can then be saved or discarded, depending on which part of the solution you want.
The plural of a piece of paper is "pieces of paper."
The parts of this apparatus include the bladder, aneroid gauge, tubing, and ear piece.
you have to look at the piece of paper and the things that are on the piece of paper follow it
