Liquid Sample Preparation – Applications

Photonic BioSystems’ liquid sample preparation technology has extensive application in a variety of industries and subset markets.

The Liquid Sample Preparation technology is ideal for:

Harvesting cell-culture fluids:

  • when highly valuable to ensure the collected media sample is not contaminated
  • to minimize risk of fluid pooled from multiple sample vessels for efficacy getting batch co-contamination
  • to clarify or sterile filter aspirated fluid harvested directly into a sterile vessel

Processing and collecting a controlled definitive volume of sample fluid:

  • controlled by the suction tool and collection vessel implementation
  • minimizes contamination of containers and handling materials used for sample transport or measurement

Withdrawing small volumes of fluid out of reagent vessels, filtering, and then dispensing finally:

  • to remove potential particulates or microbial contaminants from the reagent
  • uniquely dispense the filtered sample directly at the point of use e.g. into an assay vessel
  • a considerable benefit for controlling contamination risks in cell culture, microbial, and bioassay work


For microbial testing or the bioassay of cells, users are able to:

Complete the entire MF procedure – from sample collection to analysis – without ever opening the Filter Assay Cartridge or exposing the sample to the external environment:

  • All assay steps conducted in situ within the enclosed filter system
  • Harvest organisms, administer culture media, incubate, analyze culture test results
  • Cultures can be fed
  • Culture fluids can be harvested
  • Organisms can be cultured on – or within – the filter matrix
  • Planktonic cultures of organisms in fluid state is directly applicable
