springs compensate for wells that have different volumes of frozen culture
and would not be sampled if we used a fixed pin replicator. The photo
on the right illustrates how by pushing down on the replicator the springs
are compressed up and thereby apply equal pressure on all the pins to the frozen
substrate below. This is superior to just having a gravity floating pin as
it will melt the ice faster.
replicators can be used manually with a handle or on any of the
34 robotic systems we have mounting plates
for. The replicators can be autoclaved or sterilized with bleach or
alcohol dipped and flamed.
408FS2AS replicator on the right has a 2 ul slot in the tip of the pin to
collect the sample by capillary action.
