We have recently heard that our source (ACCO) for the cotton rolls used
to plug 1/4 pint glass bottles and plastic bottles is drying up. I
would like to know where other Drosophila labs obtain the cotton rolls
they use for plugging bottles. Are there alternate materials besides
foam or cardboard caps that some labs might suggest useing as plugs?
