Hygiena SystemSURE II ATP Bioluminescence Detector

Overview

The Hygiena SystemSURE II ATP Bioluminescence Detector is a handheld, field-deployable luminometer engineered for rapid, quantitative assessment of surface and liquid hygiene status in food production, healthcare, hospitality, and manufacturing environments. It operates on the principle of bioluminescence—measuring adenosine triphosphate (ATP) as a universal marker of organic residue. Upon contact with the proprietary UltraSnap™ ATP swab (Part #: US2020), ATP reacts with luciferase and luciferin to emit photons proportional to microbial and/or somatic cell load. The SystemSURE II captures this light signal via a high-sensitivity photodiode detector, converting it into Relative Light Units (RLUs) with traceable linearity across its full 0–9999 RLU range. Unlike spectrophotometric or culture-based methods, this assay delivers actionable data within 15 seconds—enabling real-time verification of cleaning efficacy and immediate intervention when thresholds are exceeded. Its design adheres to core principles of environmental monitoring: speed, reproducibility, portability, and compatibility with established sanitation validation frameworks such as HACCP, SSOPs, and ISO 22000.

Key Features

• Compact, palm-sized form factor (145 × 75 × 35 mm) with ergonomic grip and IP54-rated enclosure for resistance to dust and incidental moisture
• High-stability photodiode detection system calibrated against NIST-traceable standards; achieves ±5 RLU or ±5% accuracy per ISO 17025-aligned verification protocols
• Integrated 15-second assay cycle—no warm-up, no reagent preparation, no external incubation required
• On-device storage of up to 500 test records with timestamp, location tag (manual entry), and user ID assignment
• Dual-power architecture supporting alkaline (LR6/E91, 1.5 V nominal) or rechargeable NiMH/NiCd (1.2 V nominal) AA cells; rated for ≥6000 assays per alkaline pair at 20 °C
• Menu-driven interface with multilingual support (English, Spanish, French, Chinese); no software training required for basic operation
• EIA-232 serial interface compliant with RS-232 specifications for direct connection to Windows-based PCs and LIMS integration

Sample Compatibility & Compliance

The SystemSURE II is validated exclusively for use with Hygiena UltraSnap™ ATP swabs (US2020), which feature a pre-moistened, one-step collection-and-reaction design eliminating pipetting, dilution, or cold-chain handling. Each swab contains lyophilized luciferase/luciferin reagents stabilized for 12 months at 2–8 °C or 6 weeks at ≤25 °C—significantly extending shelf life versus conventional dry-enzyme formats. Swab geometry ensures consistent pressure application and uniform surface coverage (≥10 cm²), minimizing operator variability. The entire workflow—from swabbing to RLU readout—meets requirements for routine environmental monitoring under FDA Food Code Annex 2, USDA FSIS Directive 7120.1, and ISO 22000:2018 Clause 8.2.3. While not a replacement for microbiological culture, ATP data serve as a scientifically accepted proxy for residual contamination in validated cleaning programs, supporting GLP-compliant recordkeeping when paired with DataSURE II software audit trails.

Software & Data Management

DataSURE II is the official desktop application for SystemSURE II, providing secure, structured analysis of hygiene monitoring datasets. It supports automated import via RS-232, batch report generation (PDF/CSV), statistical process control (SPC) charting (X-bar/R, trend analysis), and customizable pass/fail threshold mapping across 100 user-defined limits. All data modifications—including result edits, threshold adjustments, or user account changes—are logged with immutable timestamps and operator IDs, satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed on validated IT infrastructure. The software also enables cross-site benchmarking using Hygiena’s industry-standard RLU interpretation matrix (e.g., 100 RLU = action required), facilitating consistent decision-making across global supply chains.

Applications

• Food processing: Verification of CIP/SIP effectiveness on conveyors, fillers, mixers, and packaging lines
• Healthcare facilities: Rapid assessment of high-touch surfaces (bedrails, IV poles, OR tables) pre- and post-disinfection
• Restaurant & retail: Daily SSOP compliance checks on prep tables, slicers, refrigerated display cases, and beverage dispensers
• Pharmaceutical manufacturing: Non-viable surface monitoring in Grade C/D cleanrooms where microbial enumeration is impractical
• Public infrastructure: Sanitation validation in airports, schools, public transport, and Olympic venues (validated during Beijing 2008 Games)

FAQ

What does an RLU value represent, and how is it related to microbial load?
An RLU (Relative Light Unit) is a dimensionless output quantifying photon emission intensity from the ATP-luciferase reaction. While not directly equivalent to CFU/mL, empirical correlation studies show strong linear relationships between RLUs and total viable counts (TVC) on standardized surfaces—particularly when using UltraSnap™ swabs under controlled sampling conditions.
Can SystemSURE II be used with third-party ATP swabs?
No. Hygiena does not guarantee performance, accuracy, or regulatory compliance when non-UltraSnap™ swabs are used. Reagent formulation, swab matrix, and enzyme kinetics are co-optimized for SystemSURE II hardware.
Is calibration required before each use?
The instrument performs automatic zero-point correction prior to every measurement. Full calibration is performed annually using Hygiena-certified reference standards (Cat. #CAL-01) and documented per ISO/IEC 17025 internal procedure.
How is data integrity maintained during transfer to DataSURE II?
All communications use ASCII-based EIA-232 protocol with CRC error checking. Data packets include checksums and sequence identifiers to prevent truncation or misordering during transmission.
Does the device meet international electromagnetic compatibility (EMC) standards?
Yes. SystemSURE II complies with EN 61326-1:2013 (industrial EMC) and EN 61000-6-2:2019 (immunity) and bears CE marking for sale in EU markets.
