Abstract

The present disclosure relates to a consumable sample partition device and it assembly and use. The sample partition device can be used to test a sample for absence of microorganisms (sterility) and/or for concentration of said organisms (bio-burden). The sample partition device partitions the sample input volume into multiple discrete measurement zones with little or no loss of sample (e.g., zero-loss) and with little operator involvement, thereby reducing operator- and environment-based false positives.
