Update BactoBox® software

Install the latest software on your BactoBox® from Access, or download the update file.

Latest BactoBox® software is v2026.09

See what changed in v2026.09 and the software update FAQ.

Keep your BactoBox® software up to date. From software v2026.06, Access installs the latest software in one click. On older software, or without an internet connection, install from a software update file instead.

Download v2026.09

Save your CIZE data before you update to v2026.09

v2026.09 calibrates CIZE, so new values cannot be compared with values from earlier software. After the update, your BactoBox® hides all CIZE values recorded before it. Export them first.

1. In Access, open each Growth curve measurement group.

2. Click Export CSV.

Restart your BactoBox®

When the installation is done, your BactoBox® asks you to restart it. On the first start after an update, your BactoBox® may migrate its data. This takes another 5–10 min. Then your BactoBox® shows the Ready screen as usual.

Install from a software update file

Use this route if your BactoBox® runs software older than v2026.06, or has no internet connection. Before v2026.06, Access has no Install latest button. Install a software update (.swu) file instead. That also brings your BactoBox® to a version with the one-click update.

1. Download the software update file. It works for hardware v7.5 and later.

   Download v2026.09

2. Connect to Access and click Software update in the side bar. If you see the tabs Latest and Choose SWU file, click Choose SWU file.

3. Drag and drop the file into the field. The update starts at once and takes 2–5 min.

4. Restart your BactoBox® when it asks you to.

5. Run a QC test before you measure.
