Sample Identification Tags
Cryogenic-Compatible RFID and Barcode Sample Labels
Identification tags on every sample container readable at cryogenic temperatures
Purpose
Identification tags on every sample container readable at cryogenic temperatures
Context
Child of L2-CRY-INV
Principles
- ▸Cryogenic RFID tags operate at -196C using special antenna and chip designs
- ▸2D barcodes (DataMatrix) etched on metal provide permanent optical identification
- ▸Dual-identification (RFID + barcode) provides redundancy against reader failure
- ▸Unique ID links physical sample to database record with full metadata
Typical implementations
- ▸Brooks Automation CryoTag cryogenic RFID labels
- ▸Computype cryogenic barcode labels
- ▸Zebra Technologies CryoCool thermal transfer labels
Lunar considerations
- ▸Standard RFID tags fail below -40C - special cryogenic designs required
- ▸Metal-etched barcodes survive indefinitely at cryogenic temperatures
- ▸Tag adhesive must survive 100+ years of cryogenic thermal cycling
- ▸Reader technology must be robotically operable
