Scrub and wash the buffer container with hot water and mild dish soap. After the soap has been washed off, wipe the container dry with a clean towel.
Focus the stream from the steamer over the buffer container and rubber gloves to help sterilize the two items. Do not rewipe the container or gloves with a clean towel, just leave them alone.
Let the gloves cool down for 15 minutes, put them on, and then place the peptides into a sterilized buffer container. Put the buffer lid on the container immediately afterwards.
Set your freezer or a freezing chamber to negative 4 degrees ("-4"), and then put the buffer container in the freezer.
