Bill, plastic is fine. I like glass because the suction seal is better but they need to be handled carefully.. Either can be soaked in 3-5% H2O2 to sterilize.

" Get one male from any source and you messed up the whole concept".
can be avoided if unsure with cath tube, leave it out, if you get egg it is 100%.. but it's like buying fish from a supplier and "assuming" you are getting what you bought. In this case, there is zero margin for error and learning the process assures success but it may take a purchase of 300 fish to get 100 confirmed females and each fish has to be individually sedated, that's very labor intensive but the only way to do it correctly. $30-$50 per fish is not unrealistic because you have "possibly" 200 males nobody wants except for free..
