Hi,

We use Spectra/Mesh nylon filters for separation
of different stages of worms.  They are manufactured by:
Spectrum Medical Industries, Inc
1100 Rankin Road, Huston, Texas 77-73-4716.
800-634-3300.  Fax: 713-443-3100
Spectrum Europe B.V. - 0031-76-719419

By the way, here is a list (originally from Steve Salser)
of filter sizes and their use:

10u Lets L1 thrugh but inefficient  (of course these are very pure)
13u Lets L1 thrugh very well, but stops many older stages
20u Stops eggs.  Great for letting L1 and L2 through (maybe even later stages)
35u Worm book says "use this for males"
50u and 100u Good for stopping gravid hermaphodites and letting everything
else through.

	Javier
