SUMMARY: During the removal of samples from thick‐walled vessels, either by pouring or pipetting, the remaining liquid frequently became contaminated, no matter whether the vessel was closed by a rubber bung or a glass Kali bottle top over a cotton wool plug. This was not the case with vessels of thin heat‐resistant glass. It seems that the necks of thin‐ but‐not thick‐walled vessels can be sterilized in the bunsen flame.
