back from the summer holidays a doubt has arisen.
Do I have to sterilize 1.5 Ml PLASTIC tubes (the eppendorff) and I have some glass jars with lid (jam jars).
I have to put them in the autoclave sealed or with the cap slightly unscrewed?
I usually put them unscrewed and then, WHEN the sterilization cycle has finished, I close them immediately.
Tips?
