Spread Plate versus Pour Plate Correction Volume Note Generator
Bounded culture-plating volume distinction, no correction for viability, colony recovery or safe culturing protocol.
Description
Spread Plate versus Pour Plate Correction Volume Note Generator: look up a supported built-in reference entry.
A colony concentration uses the volume of original sample plated. Added culture medium and the original inoculum are different volumes.
This tool returns a built-in reference entry for an exact supported selector. The supported entries and their scope are part of the tool; no website or current external table is queried.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Match spread or pour to the built-in method note. Both notes require the actual sample volume; the pour note distinguishes inoculum from molten agar.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| method | Method. | Exact value: "spread", "pour" |
| method | Built-in entry |
|---|---|
| "spread" | Use actual plated sample volume when computing CFU/mL; no universal 0.1mL volume is assumed. |
| "pour" | Use actual inoculated sample volume when computing CFU/mL; molten-agar volume is not the original sample volume. |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.reference | The stored entry for the exact selected key; its type may be text, a number or a list. |
{
"input": {
"method": "spread"
},
"output": {
"result": {
"reference": "Use actual plated sample volume when computing CFU/mL; no universal 0.1mL volume is assumed."
}
}
}Limitations and assumptions
- This lookup does not calculate CFU/mL or assume a universal plated volume.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
