Cancel the OPU

Ask the team to delay the OPU until the dishes equilibrate

Quickly label a dishes and collect the oocytes in warmed HEPES buffered media from the incubator

With HEPES and then I can take as long as I want

Work quickly all of the time

Squeeze and hold the lid really tightly so no gas can escape
