Storage Locations

The Storage Locations page records the physical places where samples and aliquots are kept (fridges, freezers, shelves, boxes) together with each location's environmental specification (ISO/IEC 17025 §6.3.3, §6.3.4). Every location is the anchor for Environmental Readings and for the storage position of each aliquot in the Aliquot Archive.

Found under: Reagents & Storage → Storage Locations.

Fields

Field	Description
Code	Short unique code of the location, e.g. `FR-01` (up to 50 characters)
Name	Descriptive name, e.g. "Sample Fridge 1" (up to 150 characters)
Temperature min / max (°C)	Acceptable temperature range (hidden columns)
Humidity min / max (%RH)	Acceptable relative-humidity range (hidden columns)
Pressure min / max (hPa)	Acceptable atmospheric-pressure range (hidden columns)
Monitoring interval (hours)	How often a reading must be logged for this location — shown in the table as "Interval (h)"
Notes	Additional remarks

Environmental limits

Temperature, humidity and pressure limits are optional. When an Environmental Reading is logged for the location, the measurement is compared against these limits: a blank limit means "no restriction on that side", and a value outside the limits is flagged as an excursion. Set only the limits that matter for the location — a fridge needs temperature alone, a dry store may also need humidity.

Monitoring interval and alert

ISO 17025 §6.3.3 requires the laboratory to monitor environmental conditions — not merely to note them when someone happens to look. Without a declared interval, a sensor that has stopped working is indistinguishable from a location that simply shows no excursions.

Blank — the location is not on a monitoring schedule and is excluded from the "Locations with no recent reading" alert.
A value in hours — if the location's latest reading is older than this interval, or there is no reading at all, the location counts towards the Locations with no recent reading alert on the "Quality System Compliance" card of the Dashboard and in the periodic QC digest (email). "No reading at all" counts on purpose: a location that has never been recorded is exactly the one that slips by unnoticed.

Set the interval per location, according to how often you actually log it: e.g. 24 for a fridge logged daily, 168 for a dry store checked once a week.

If this is missing

🔴 A location with no reading interval is not monitored at all. The alert query filters on

readingIntervalHours IS NOT NULL, so a location without one never appears as overdue —

not on the compliance card, not in the digest. It looks clean because it is not being checked,

not because it is fine.

A location with no temperature or humidity limits accepts readings normally, but **none can ever

fall out of limits** — there is no limit to breach.

A location that refuses to delete has aliquots or readings attached; that is deliberate.

Notes

The code is unique; saving fails if a location with the same code already exists.
The location is picked on the aliquot (the "Storage Location" field when editing an aliquot) and is available as a filter in the Aliquot Archive.
A location that still has aliquots or environmental readings linked to it cannot be deleted; move the aliquots to another location first.
