96-well plate layout planner
A spreadsheet can draw a plate. It will not reliably keep samples off the edge, balance groups, or tell you which rules failed.
For people who pipette from a map and need the assignment to match the rules they set.
No unsatisfied constraints on this example. Edge-well rules for a 96-well plate layout.
How it works
01
Load samples
CSV or XLSX with sample IDs and the columns your rules use.
02
Set rules
Plates, controls, blanks, replicates, reserved wells, edge wells, grouping, and randomization.
03
Check the map
Look at the plate and the report. Unsatisfied rules are listed, not dropped.
04
Export
A plate map plus the inputs, rules, seed, and software version.
Constraints and checks
- 96-well plates
- Controls, blanks, and reserved wells
- Replicates and case–control balance
- Samples that must sit together or stay apart
- Edge-well rules
- Randomization with a recorded seed
- CSV and XLSX export
What it will not do
- Not a LIMS, inventory system, or notebook.
- No Hamilton or Tecan worklists yet. Those only ship when we can check them.
- Does not analyze plate-reader data or fit curves.
- Will not invent rules from a vague prompt.
Why the edge is a constraint
- Edge-well rules for a 96-well plate layout
The outer 36 wells of a 96-well plate are the usual source of evaporation and position bias. The planner can reserve them, put blanks or controls there, and report it if a sample still lands on the edge.

Questions
- Can I exclude edge wells?
- Yes. You can leave the outer rows and columns empty, or put blanks or controls there, and keep unknowns off the edge.
- Does it randomize across plates?
- It assigns samples across one or more 96-well plates using the rules you set. If a rule cannot be met, the report says so.
- Is this a free plate map template?
- It is a working planner, not a blank grid. Assignment, a validation report, and CSV or XLSX export are free and run in the browser.
- Do I need R, Python, or an account?
- No. Open the page, load a table, export a map.
- What file do I get back?
- A CSV or XLSX plate map, plus a record of the input summary, rules, random seed, software version, and layout.
- Will it write Hamilton or Tecan worklists?
- Not yet. We will only add formats we can check.
