Tylka Nematology Lab

Procedure:

• Assemble the Baermann funnel apparatus.
• A clamped rubber tube is placed below the funnel
• A piece of window screen (or similar material) is placed in the mouth of the funnel
• The funnel is placed into a rack or holder

• Place a tissue-paper wrapped soil sample onto the screen material.

• Add water to the funnel setup until the screen and soil sample are immersed.
• Wait overnight (or longer if desired).

• Gather the first couple of drops of water from the bottom of the tube by slowly releasing the clamp on the tubing.
• Examine under the microscope. Note that this technique will work only with actively mobile, living nematodes.
