Overview
The Stat Fax 2100 Microplate Reader is a benchtop absorbance-based microplate detection system engineered for precision, reliability, and ease of use in clinical diagnostics, biomedical research, and quality control laboratories. Designed and originally manufactured by AWARENESS Technology—a U.S.-based company with over three decades of specialization in optical microplate instrumentation—the Stat Fax 2100 employs dual-beam photometry with tungsten-halogen illumination and interference filter-based wavelength selection to deliver high reproducibility in ELISA, enzyme kinetics, cell viability, and colorimetric assays. Its optical architecture conforms to fundamental Beer-Lambert law principles, enabling accurate quantification across a broad dynamic range (–0.20 to 3.00 Abs), validated against NIST-traceable standards. The instrument features built-in self-calibration diagnostics—including Dri-Dye™ verification strips—to routinely assess photometric accuracy, linearity, and inter-plate repeatability without external reference equipment.
Key Features
- Dual-beam optical path with automatic background subtraction for enhanced signal stability and reduced drift
- Integrated 4-position or optional 6-position interference filter wheel (10 nm bandwidth, hard-coated cavities) supporting wavelengths from 340 nm to 630 nm
- Onboard Z80A/Z180 microprocessor with battery-backed RAM storing up to 36 user-defined assay protocols and calibration curves
- High-contrast 2-line alphanumeric LCD display (24 characters per line) with intuitive step-by-step guided operation
- Configurable plate agitation: variable-duration, fixed-speed orbital shaking for uniform reagent mixing prior to reading
- Robust mechanical design: flame-retardant ABS housing with reinforced metal base; compact footprint (43 × 37 × 18 cm) and portable weight (13.7 kg)
- NRTL-certified and CE-marked for compliance with North American and European electrical safety directives
Sample Compatibility & Compliance
The Stat Fax 2100 is optimized for standard 96-well microtiter plates (flat-bottom, U/V-bottom, and tissue-culture treated formats). It supports both endpoint and kinetic absorbance measurements in accordance with widely adopted regulatory frameworks including CLIA, ISO 15197 (for in vitro diagnostic applications), and FDA-recommended practices for assay validation. Photometric accuracy (±1% or better vs. NIST SRM 930e) and 8-hour baseline stability (< ±0.005 A drift) meet requirements for GLP-compliant data generation. While the system does not natively support 21 CFR Part 11 electronic signature functionality, its audit-ready print logs—generated via parallel or serial interface to HP DeskJet, Canon Bubble Jet, or Epson-compatible printers—facilitate manual record retention in regulated environments.
Software & Data Management
The embedded firmware provides comprehensive on-instrument data processing without external PC dependency. Assay calculations include linear regression, polynomial curve fitting (up to 4th order), point-to-point quantitation, threshold-based classification, and multi-point % absorbance normalization. All operations feature real-time user prompts, error flagging, alphanumeric test naming, and localized plate reading (user-selectable wells or rows/columns). Internal clock/calendar timestamps all results. Optional auto-read mode initiates measurement upon plate insertion; “copy” and “edit curve” functions allow protocol refinement between runs. Raw absorbance values are output via RS-232 (2400 baud, 8N1) or Centronics-style parallel port—compatible with 80-column printers having ≥2 KB buffer memory.
Applications
The Stat Fax 2100 serves as a primary detection platform for ELISA-based immunoassays (e.g., IgG/IgM serology, cytokine profiling), enzymatic activity assays (e.g., LDH, ALP, HRP-conjugated systems), bacterial growth monitoring (OD600), MTT/XTT cell proliferation studies, and total protein quantification (Bradford/Lowry). Its 340 nm capability enables NAD(P)H-linked dehydrogenase assays, while extended VIS coverage (405–630 nm) accommodates common chromogenic substrates such as pNPP, TMB, ABTS, and o-phenylenediamine. Routine use spans core facilities, hospital labs, contract research organizations (CROs), and academic teaching laboratories requiring traceable, low-maintenance absorbance measurement.
FAQ
What wavelength options are available on the Stat Fax 2100?
Standard configurations include 405, 450, 492, and 630 nm; optional 6-VIS models add 545 and 600 nm; 6-UV variants include 340 nm for NADH detection.
Does the instrument support kinetic readings?
Yes—programmable time intervals between consecutive reads enable basic kinetic absorbance monitoring across defined durations.
How is photometric performance verified?
Using the included Dri-Dye™ calibration strip, users perform routine checks for accuracy, linearity (0.0–2.5 A), and intra-assay CV (<2%).
Can assay data be exported to a computer?
Raw absorbance values and calculated concentrations can be printed directly; digital export requires third-party serial-to-USB adapters and terminal emulation software.
Is service and technical support available outside the U.S.?
Global distribution and field service are coordinated through authorized regional partners, with documentation and firmware updates accessible via secure OEM portal.
