How to use Plasmid Stock Box Mapper
- 1Type a plasmid stock label, then click an empty position in the 9×9 box to place it.
- 2Click a filled position to free it up when the sample is used or moved.
- 3Export the map to CSV to print a box sheet or share the layout with the lab.
Why use Plasmid Stock Box Mapper?
- ✓Find any plasmid stock fast: a visual 9×9 box map means no more digging through a frosted box and warming everything up.
- ✓Tracks free vs. used positions so you know capacity at −20 °C before you walk to the cold room — and exports the map to CSV for sharing.
- ✓Runs offline in the browser; sample labels and positions never leave your device, which suits molecular-biology labs handling confidential material.
Frequently asked questions
How does the box mapper work?+
It draws an interactive 9×9 box grid. Enter a label for the plasmid stock, click an empty position to fill it, and click a filled position to clear it. A live counter shows used and free positions, and you can export the whole map to CSV — all in your browser, with the layout saved locally between visits.
Why map a freezer box instead of using a list?+
Because retrieval time and freeze-thaw damage are real costs. A visual map of plasmid stocks lets you walk straight to the right position, minimising how long the box sits out of −20 °C. It also reveals free slots at a glance so you stop over-filling boxes.
Is the box layout saved?+
Yes — it is stored in your browser's localStorage, so the map is still there next time you open the tool on the same device. Nothing is uploaded; export to CSV when you want a printable box sheet or a backup.
Can I use it for different freezer formats?+
This variant is sized as a 9×9 box, which fits common −20 °C storage for plasmid stocks. For a different format, use the matching box, rack, tower or fridge map in this collection — together they cover the standard cryostorage layouts.
