Slightly off topic -

Does anyone here grow and freeze their yeast?

I'm after something like a vial to freeze it in, have no idea where to get one (checked a couple of NZ lab supply websites with no luck) or what the proper name for it is, any ideas?

Erlenmeyer flasks are commonly used for that sort of thing, though I don't believe they seal. You can get stoppers for them though.

Cheers, I've seen the conical flasks for making starters but looking for something small and airtight (and preferrably boilable to sterilise) to freeze the yeast in, I'm guessing they'd be about 15mL, I'll have to re-read the thread on HBT.

I have a few small glass bottles (I think they are called bijou s) some have metal lids other plastic, all about that size. I got them from a lab supply place but they have been used before. I don't know what for though. There are quite a few here so am more than willing to part with some if your interested. The ones I have used I put through the autoclave at work - no probs there. I would assume that freezing would not be a problem either.

Cheers mate, might hit you up about it later if I don't have any luck.

The reason I said about boiling is that I heard on HBT that some have seals that bugger up when boiled. I'll do a search under the name you suggester. Thanks again :-)
