Using safety lid
NOTICE
During isoelectric focusing, do not lean on the safety lid, do not
apply excess pressure or uneven weight to the lid, and do not place
any items on the lid. Such pressure could cause arcing between
the strip holder electrodes and the electrode areas, damaging the
instrument.
When using the Ettan IPGphor standard strip holders, lid adapters must be used to apply
the correct amount of pressure to the lids of the IPGphor strip holders. The pressure
keeps the IPG strip in contact with the IPG strip holder electrodes.
