Absorbance and water dispensation

We find no relevant differences between the measures before and after the dispensation of different volumes of water in the well, both for bacterial coltures and simple liquid growing medium.

Absorbance and water dispensation

Absorbance and volume

The proportionality between absorbance (OD600) measurement and volume of colture in the well was verified.

Absorbance and volume

Absorbance and diluitions in liquid growing medium

The proportionality between absorbance measurement (OD600) and colture's diluitions was verified, confirming the possibility of using OD600 to measure the bacterial quantity in the well, regardless of the total volume present in the well.

This experiment was done in two different growing mediums, LB and M9, and in three different total volumes in the well, 100μl, 200μl and 300μl.
