Blood Banks & Tissue Storage

Tight windows, serious consequences

• Whole blood & red blood cells: 1–6°C (typical)
• Platelets: 20–24°C with continuous gentle agitation
• Plasma (frozen): ≤ -18°C, often -30°C or colder
• Tissue & organs (ultra-low): -80°C and below in LN₂ systems

A brief excursion outside these ranges can invalidate a unit — and for tissue and platelet products, the loss is irreversible. AABB and FDA inspectors look for continuous records, NIST-traceable calibration, and documented response procedures for excursions.

Why the probe variant matters here

The NEO-1P and Neo-1P NIST place a stainless-steel probe inside the unit, not just in the ambient air. For blood bank refrigerators, this is the defensible placement: you're measuring the temperature of the product, not the temperature of the air around the rack.

The AABB / FDA audit picture

Inspectors expect to see:

• Continuous temperature records for every monitored unit
• NIST-traceable calibration certificates on file, within annual re-verification window
• Alert logs showing who was notified and how fast
• Response procedures documented and followed for every excursion
• Exportable PDF records that match the sensor serial on the calibration cert

iMatrix Cloud produces all of these in one signed export per audit window.

Typical deployment

One NEO-1P NIST per unit, with the probe in the blood-product tray. A Micro Gateway per lab room bridges 20–50 sensors to iMatrix Cloud. Alert thresholds configured tighter than regulatory requirements so the lab tech knows about a drift before it becomes an excursion.
