# DIY dilution dispenser

<img src="/files/Kodg0Xsw6KGQBcWyCLRj" alt="" class="gitbook-drawing">

This page teaches you how to assemble and use the [dilution dispenser](/encyclopedia/item-register/accessories/dilution-dispenser.md). You use it to make a DIY[^1] dilution vial with SBT [dilution liquid](/encyclopedia/item-register/vials-flasks-and-liquids/dilution-liquid-5-l.md).

The workflow has three steps:

{% content-ref url="/pages/OtpnJGIVPwbjx2CtcGl2" %}
[Assemble dilution dispenser](/custom/do-it-yourself-diy/diy-dilution-dispenser/assemble-dilution-dispenser.md)
{% endcontent-ref %}

{% content-ref url="/pages/vdutnlyN9tARZsmyOhMw" %}
[Make DIY dilution vial](/custom/do-it-yourself-diy/diy-dilution-dispenser/make-diy-dilution-vial.md)
{% endcontent-ref %}

{% content-ref url="/spaces/eYTtd7c0A325muFr5lMW/pages/SpjYhz2h0K4wK9HpcHAV" %}
[QC test](/getting-started/qc-test.md)
{% endcontent-ref %}

{% hint style="success" %}
[Replace the syringe filter](/custom/do-it-yourself-diy/diy-dilution-dispenser/replace-syringe-filter.md) at the start of each day.
{% endhint %}

## Consider the SBT dilution vial (bundled as `DV01`)

If possible, we recommend that you use the SBT [dilution vial](/encyclopedia/item-register/vials-flasks-and-liquids/dilution-vial.md) (bundled as `DV01`) instead. This avoids many of the [pitfalls with DIY dilution vials](/troubleshooting/qualification-fails/dilution-vial-is-outside...md).

## Use the SBT dilution vial (bundled as `DV01`)

The SBT dilution vial pairs perfectly with your BactoBox®. It avoids all the [pitfalls of DIY dilution vials](/troubleshooting/qualification-fails/dilution-vial-is-outside...md).

The SBT dilution vial is filtered, conductivity-adjusted, and long-term stable thanks to gamma radiation sterilization.
