# Sample Aliquoting

## Overview

An [aliquot](https://study.com/academy/lesson/using-aliquots-in-chemistry-definition-function.html) is a type of sub-sample that is taken or extracted from an original sample.

It is always tedious to document the sample aliquoting process in a LIMS. Labii made it easy with the **Sample Aliquoting** widget.

The widget enables you:

1. Create sample records for the number of aliquots in bulk.
2. Manage the list of aliquots.
3. Create consumptions for the sample to tracking the usage

### Requirements

This widget relies on other configuration, please make sure these configurations in place to make it work:

The below 2 tables are needed. They can be created by using a table type. If your organization is created using the Inventory application, these tables will be created directly.

* samples
  * source\_samples
  * volume\_value
* consumptions
  * source
  * amount

### Configure aliquoting

Before start creating the aliquots, a few settings need to be configured first:

* **Column \[Source samples]** - Select the column that defines the Source samples. The created aliquots will be linked to the sample from this column.
* **Column \[Volume Value]** - Select the column that defines the Volume Value. The volume value will be assigned to this column and the total volume will be subtracted from the parent sample.
* **Number of aliquots** - The number of aliquots to create
* **Aliquot volume value** - The volume for each aliquot. If different volume needs for many batches of aliquots, update this value to recreate the aliquots.
* **Table \[Consumptions]** - Configure the consumption table. If this table is not selected, the configuration table will not be created.
* **Consumption column \[Source]** - Select the column that defines the Source of the consumption.
* **Consumption column \[Amount]** - Select the column that defines the Amount of the consumption.

### Create aliquots

Click the **Create x Aliquots** button to create aliquots. Once clicked, a progress bar will show you creating progress. The aliquot will be named after the sample by appending "**(aliquot x)**".

You can click the button again to create a second batch.

Please note the log will be documented at the bottom of the widget.

### Manage aliquots

A list of aliquots will be displayed once created. By default, only 10 aliquots will be displayed, you can click the **Load More** to load a second page. You can also click the **List View** button to manage the aliquots in the list view.

### Checkout aliquots

To check out aliquots, change the `is_consumed` to `True`

### The consumptions

The widget will also create consumption for you. Consumption indicates how the sample is used. The experiment field of consumption will remain empty.
