That's ok I was just going to swab the hospitality kitchen and incubate plates after, all good I will just make new agar and just throw out the previous nutrient agar bottle. Thanks for youre help

OK that's what I thought i'll pull it out of the fridge melt it and the re autoclave it, then pour.

Its just to take swabs of a hospitality kitchen,they wanted agar plates but I have nutrient agar does it really matter if I don't use just plain agar and use nutrient agar? The results should still be the same no?

Hi Just wondering,

I made up some nutrient agar for a bacteria prac not that long ago and had some left over. I put the left over agar bottle in the fridge. Obviously it has hardened. I was wondering do I use a water bath to melt this agar then pour it straight into the plates OR do I need to melt it then re autoclave it then pour it?

Thanks kel
