Space and table requirements

The size and weight for the instrument 
portion of the QPix 400 Series are provided 
below. The instrument should be accessible 
on the front, sides, and back of the 
instrument to allow service access to the 
filters and other preventative maintenance 
replacement parts.

The QPix 450 or 460 comes with its own 
table, but the QPix 420 is optional. It is highly 
recommended to use the Molecular Device 
table designated for the QPix 420. 3rd party 

tables will have to be at least as sturdy 
and have the appropriate clamps in order 
to prevent the instrument from excessive 
shaking.
