Automated precision sampling for improved results
Manual sampling is time-consuming and prone to heterogeneity due to inherent human variability during the sampling process. This heterogeneity can negatively affect the reproducibility of the results, jeopardizing the research’s perceived value [1].
Also, human interaction during sampling usually requires the experiment to be halted and can inadvertently introduce contamination [2].
A precision sampler designed for cell perfusion
The advantages of dynamic cell culture regarding improved physiological relevance are becoming ever more established [3].
To profit from the advantages of dynamic cell culture, precision sampling must be adapted to the continuous media flow without disrupting cell culture. The precision sampling Pack was designed to precisely do that.
Collect samples adapted to your application
Precision sampling must match the analysis to be performed afterward. Some assays, such as Elisa and mass spectroscopy, require minute volumes as low as 100 µl.
A precision sampling system must enable sample volumes that align with these requirements.
The precision sampling Pack allows the collection of volumes down to 100 µl and at defined periods with an easy and user-friendly automation setup.

Precision sampling principle
Several applications can benefit from automated precision sampling. Here, the synergistic effect of two drugs is explored as an example. A µ-Slide III 3D Perfusion from ibidi is used to culture cells.
Channel A is a negative control in which only the medium is perfused.
Channel B explores the synergistic effect of Drug 1 and Drug 2, with an initial exposure to Drug 1 followed by the concurrent perfusion of Drugs 1 and 2.
Channel C is a positive control, with the perfusion of only Drug 2. Each channel is connected to a rotary valve programmed to collect samples of 150 µl every two hours automatically. The samples are then analyzed for the temporal secretion of specific molecules linked to the action of the drugs on the cells.
Automated precision sampling applications
- Temporal release of cytokines by brain cells.
- Release of extracellular vesicles.
- Molecular released during inflammatory responses.
- Uptake and metabolism of substances of interest.
