It only takes 2 actions to configure a protocol in order to activate the tracking of your samples within each experiments executions.

In this article, we will see how to define the settings related to the samples traceability.

The consequence of this configuration (during experiment preparation and report), is available here: Fill samples information during preparation for a full traceability and here: Complete and retrieve 🏷️ sample info at the end of the experiment

1 - Add a sample reference in your labware

This step is necessary to indicate the operator in which labware the sample liquid will be contained during the preparation of the experiment.

In the meantime, it allows to mark a clear difference between reagents and samples in the protocol definition.

How to do it

a. Select a labware (can be a tube or a multi-well) then open the “Labware info” panel ; if applicable, select the well or group of wells that you want to fill.

b. You can now choose between filing your labware with a reagent or a sample reference ; in our case we will add a Sample by clicking on the text field.

Note: To create bulk sample reference, use the solution at start import tool.

c. Enter a Sample reference name that will guide the experiment operator during the preparation, "DNA Sample 1” for example.

d. After that, you can fill another vessel or well with:

  • The same sample reference ; OneLab will autocomplete your entry (see above)
  • A new sample, e.g. “DNA Sample 2”

All along the design on the protocol, you will be able to inspect the content of each vessel or well and find out where the sample goes ; you just have to spot the Sample tag.

Notes:

  • A sample reference shares the same name, concentration and description ; on the other hand the volume can be set independently in each container.
  • Unlike reagents, sample references are only related to the current protocol ; OneLab will help you design your protocol by autocompleting the sample reference name if you want to reuse an existing one.

2 - Define the labware target of your experiment

To avoid creating useless tracking data, OneLab requires you to select which labware will host the prepared-processed samples.

⚠️ This actions is crucial to enables OneLab to record sample information at the end of the experiment and on top of that, to let you export sample information to use with other software.

How to do it

a. Select a labware (can be a tube or a multi-well) then open the “Labware info” panel.

b. Scroll to the "Labware" part and check the "Target" box.

c. Important! Make sure that this "Target" labware contains at least one sample at the end of the experiment.

Complete your protocol design

and proceed to execution by clicking on "Execute".
