The B1450-IC is a double-sided UV-C dosimetry indicator card — a single-use UV-C-sensitive card that changes color upon receiving the rated UV-C dose, confirming full-cycle decontamination in the UV Clave (B1450) chamber. Sold at $120, the indicator card provides per-cycle workflow verification that UV-C exposure has occurred to the rated dose level — important documentation for research-grade decontamination workflows where cycle-validation is part of facility protocol.

Why a Double-Sided Indicator Card
UV-C decontamination is surface-only — light doesn't penetrate solid materials or reach shadowed surfaces. Validating that UV-C dose actually reached every surface of every item is part of the cycle-verification workflow. A double-sided indicator card placed inside the chamber during the decontamination cycle provides:
- Top-surface validation — confirms UV-C dose reached items on the chamber's upper surfaces / top of decontamination load
- Bottom-surface validation — confirms UV-C dose reached items on the lower surfaces / bottom of decontamination load
- Position-checking workflow — placed in different chamber positions across cycles, builds a coverage map of the chamber's UV-C dose distribution
Pick the double-sided card (B1450-IC) when:
- Workflow includes per-cycle decontamination verification (research-grade documentation)
- Cycle-coverage validation is part of facility decontamination protocol
- Multi-position dose mapping is needed to validate chamber loading patterns
- Educational microbiology programs demonstrating UV-C decontamination concepts benefit from visual color-change verification
Pick the smaller-format stickers (B1450-ISS) when per-item dose verification is the workflow — small stickers attach directly to specific items being decontaminated.
UV-C Dosimetry Format Comparison
| SKU | Format | Best for | List price |
| B1450-IC (this product) | Double-sided card | Per-cycle chamber-coverage validation | $120 |
| B1450-ISS | 0.5"×0.5" stickers | Per-item dose verification — sticker attaches to individual items | $107 |
Application Profile
Per-cycle decontamination verification — research-grade documentation that the UV-C cycle delivered the rated dose.
Chamber-coverage dose mapping — periodic position-mapping cycles to validate that all chamber positions receive uniform UV-C dose.
UV-C lamp performance monitoring — declining color-change response across cycles signals UV-C lamp output degradation; informs lamp replacement timing.
Operator training documentation — per-cycle verification supports operator training on UV-C decontamination protocol.
Facility audit / quality-management documentation — color-change indicator cards serve as physical evidence of cycle execution in facility quality-management records.
Educational microbiology laboratory teaching — undergraduate / graduate decontamination-modality coursework benefits from visual UV-C dose verification.
Method-development workflows — protocol-development comparing cycle-time vs dose-delivery across different chamber loading patterns.
Ordering & Configuration
Pair with UV Clave chassis. Confirm UV Clave (B1450) inventory at order — the indicator card is workflow-incomplete without a chassis.
Confirm pack quantity. Indicator-card products typically ship in multi-card packs — confirm specific pack quantity at order to support facility cycle volume.
Plan for ongoing dosimetry inventory. If facility protocol calls for per-cycle verification, plan for ongoing replacement-card procurement.
Confirm at quote: chassis pairing, intended verification protocol (per-cycle vs periodic-mapping), pack-quantity sizing, and lead time.
Warranty: Per Benchmark Scientific standard accessory / consumable terms — confirm at quote.
