Clamps grip the bottom ends of the glass units to prevent the gel leaking.
A comb is inserted into the top of the gel to create the wells into which the samples will be loaded.
Once the gel is set, the unit is placed into the sequencing machine.
Samples are taken up with a multi-pipettor …
…and loaded into the wells of the gel.
This is a close-up from the previous photograph. Note the extremely small size of the wells and the pipettor, making it possible to load large numbers of samples into each gel.
