Abstract: A multiwell microplate for holding liquid samples, and a method of use thereof. The multiwell microplate includes a frame defining a plurality of wells disposed in a single column, each well having an opening with a length l1. A moat is disposed about the plurality of wells. A plurality of walls traverses the moat, the walls defining a plurality of compartments, each compartment having a length l2 selected from a range of greater than l1 and less than 6l1. A multiwell microplate carrier includes a body defining a plurality of regions configured to hold a plurality of multiwell microplates in parallel, each multiwell microplate defining a single column of wells, and each of the regions defining a plurality of openings that are adapted to mate with the single columns of wells.

Abstract: The accuracy and/or precision of measurements of extracellular acidification rate or CO2 evolution in cell culture medium may be improved by using materials with low CO2 permeability for medium-containing vessels.
