Short answer
The storage conditions field restates the storage line printed on the product label, for example “Store at −20 °C” or “Store at 2–8 °C. Protect from light.” On a Fara datasheet the text is reproduced word for word from the catalog record, with nothing added.
Each phrase names either a temperature or a condition such as light or moisture. This note explains what the words and figures mean; it does not add handling advice of its own.
1.Where the text comes from
The field holds the storage wording of the label, as entered in the catalog record. Fara prints it unchanged in the “Storage” row of the specification table and quotes it again in the sheet's query table. Spelling, units and punctuation are kept as recorded, so a label that says “−20C” is not rewritten as “−20 °C”.
When a record holds no storage text, the Storage row is left out. The handling section of the sheet then carries only the general line printed on every sheet: “Store as labelled; for laboratory research use only.” That line refers back to the label and sets no condition of its own.
2.Temperatures
Temperatures on labels are usually given in degrees Celsius, sometimes with a common name beside them. The table lists the figures and names most often seen, with the Fahrenheit equivalent.
| Label wording | What it states | °F |
|---|---|---|
| −80 °CMinus eighty degrees Celsius. | Minus eighty degrees Celsius. | −112 °F |
| −20 °C, “store frozen”Minus twenty degrees Celsius. Labels also word it “at or below −20 °C”. | Minus twenty degrees Celsius. Labels also word it “at or below −20 °C”. | −4 °F |
| 2–8 °C, “refrigerated”Any temperature from two to eight degrees Celsius. | Any temperature from two to eight degrees Celsius. | 35.6–46.4 °F |
| 15–25 °C or 20–25 °C, “room temperature”The range printed with the phrase; where figures are printed, they define it. | The range printed with the phrase; where figures are printed, they define it. | 59–77 °F or 68–77 °F |
2.1Ranges and limits
A range such as 2–8 °C includes both ends. A limit such as “at or below −20 °C” states the warmest permitted temperature and leaves the lower side open. A single figure without either wording is simply the temperature the label names. The minus sign matters: −20 °C and 20 °C are forty degrees apart, and a record copied without its sign reads as a different condition.
3.Condition phrases
- Protect from light
- The label names light as a condition the contents are to be kept from.
- Keep dry, store desiccated
- The label names moisture as the condition. “Desiccated” means held with a drying agent or in dry air.
- Keep container tightly closed
- The label asks for the closure to stay sealed while the item is stored.
- Do not freeze
- A lower limit: the label excludes the frozen state.
- At or below, not above
- The figure that follows is a limit, not an exact setting.
- Store as labelled
- A pointer back to the label itself; the phrase sets no condition of its own.
4.Reading a combined line
Labels often join several statements in one line, for example “Store at −20 °C. Protect from light. Keep dry.” Each sentence is a separate condition: a temperature, a light condition and a moisture condition. The order carries no ranking, and no condition is implied by the others. A line that names a temperature and nothing else states nothing about light or moisture.
Where a line uses a common name and a figure together, as in “refrigerated (2–8 °C)”, the figure is the precise part. Where it uses a common name alone, the name is what the label says, and the sheet repeats exactly that.
5.What the field does not state
The storage field is a restatement of the label, not a specification written by Fara. It does not describe how a parcel travels, it is not an expiry date, and it contains no procedure. Form and colour are covered by the appearance field, and substance identity by the CAS registry number.
