Tips for labeling tissue culture plates so that lids can be matched to their base

In the instance you have multiple tissue culture plates in use, it is worth making sure that the lid and base of the plates can be matched in case several lids are off at once. A simple way to do this is to use a marker and draw a line down the plate. This can be done in different colors or in different positions, allowing the correct lid to be matched to the correct base quickly and easily. Alternatively, you can label both the lid and the side of the plates with an appropriate identifier.
