HAIDA HD-E803-250A Biochemical Incubator

Overview

The HAIDA HD-E803-250A Biochemical Incubator is a precision-engineered benchtop environmental chamber designed for stable, long-term temperature-controlled cultivation and storage of biological samples, microbial cultures, pharmaceutical formulations, and stability test specimens. Operating on a forced-air convection principle with air-cooled refrigeration, the unit maintains tight thermal uniformity across its working volume—critical for reproducible incubation outcomes in regulated laboratory environments. Unlike general-purpose ovens or dry baths, this incubator integrates microprocessor-based PID temperature regulation to minimize overshoot and drift, ensuring compliance with method requirements outlined in pharmacopeial standards such as USP <1151>, ICH Q1A(R3), and ISO 17025-accredited stability testing protocols. Its design prioritizes operational safety, energy efficiency, and integration readiness within modern QC/QA workflows.

Key Features

• Mirror-finish stainless steel interior chamber—corrosion-resistant, non-porous, and compliant with GLP cleaning validation requirements.
• Adjustable shelving system with multiple height positions to accommodate varied vessel configurations (e.g., Petri dishes, flasks, multi-well plates).
• R134a refrigerant-based cooling circuit—zero ozone depletion potential (ODP = 0), low global warming potential (GWP ≈ 1430), and optimized for consistent low-temperature performance down to 5 °C.
• Microcontroller-driven PID temperature control with 0.1 °C resolution and real-time deviation compensation—achieving ≤ ±0.5 °C temperature uniformity under steady-state conditions per ASTM E2500-18 Annex A3 guidelines.
• Dual-stage over-temperature protection: primary controller + independent mechanical cut-off switch—prevents sample loss during power anomalies or sensor failure.
• Front-panel LED display with intuitive icon-based navigation—enabling rapid parameter verification without menu diving.
• Standardized Ø30 mm access port on left side wall—facilitates insertion of calibrated thermocouples, humidity probes, or sampling lines without compromising chamber integrity.
• RS485 serial interface compliant with Modbus RTU protocol—supports connection to LIMS, SCADA systems, or external data loggers for 21 CFR Part 11-compliant audit trails when paired with validated software.

Sample Compatibility & Compliance

The HD-E803-250A supports a broad range of sample types including bacterial and fungal cultures (e.g., E. coli, Aspergillus niger), mammalian cell lines, enzymatic reaction mixtures, and accelerated stability test samples per ICH Q5C and Q1E. Its stainless steel construction meets FDA-recommended material criteria for non-reactive contact surfaces in pharmaceutical development labs. While humidity control is not standard on this model (as indicated by absence of RH specification), optional retrofit modules may be installed per customer request—subject to factory validation and recalibration. The unit conforms to electrical safety standards IEC 61010-1 and EMC directive 2014/30/EU. It is manufactured under ISO 9001-certified quality management systems and qualifies for inclusion in GMP-aligned facility qualification protocols (IQ/OQ/PQ).

Software & Data Management

Although the base configuration operates via standalone microcontroller firmware, the integrated RS485 port enables bidirectional communication with third-party data acquisition platforms. When interfaced with validated PC-based software (e.g., HAIDA’s optional LabLink Suite or generic Modbus-compatible tools), users can configure automated logging intervals, generate time-stamped CSV reports, and export trend graphs aligned with ALCOA+ data integrity principles. Audit trail functionality—including user login, parameter changes, and alarm events—is available upon implementation of compliant software layers meeting 21 CFR Part 11 electronic record requirements. Firmware updates are delivered via secure USB loader—traceable through version-controlled release notes.

Applications

• Microbiological culture maintenance and growth curve analysis in academic and clinical microbiology labs.
• Accelerated stability studies for APIs and finished dosage forms under ICH Q1A(R3) long-term and intermediate storage conditions.
• Enzyme activity assays requiring precise thermal stabilization at sub-ambient temperatures (e.g., 15–25 °C).
• Seed germination trials and plant tissue culture incubation in agricultural research facilities.
• Quality control of raw materials (e.g., excipients, fermentation media) where thermal history impacts physicochemical behavior.
• Validation support for sterilization process development, including biological indicator incubation per ISO 11138-1.

FAQ

Does the HD-E803-250A include humidity control capability?

No—this model is a temperature-only incubator. Humidity regulation requires an optional add-on module, which must be specified at time of order and validated separately.
Is the RS485 interface compatible with common LIMS platforms?

Yes—when used with Modbus RTU-enabled middleware, it supports integration into major LIMS vendors’ device drivers (e.g., Thermo Fisher SampleManager, LabVantage). Protocol documentation is provided upon request.
What is the maximum allowable load weight per shelf?

Each adjustable shelf supports up to 15 kg uniformly distributed; total chamber loading must not obstruct airflow paths or exceed 80% internal volume occupancy.
Can the unit operate continuously for extended periods (e.g., 30-day stability tests)?

Yes—the system is rated for uninterrupted operation under Class II environmental conditions (IEC 60721-3-2), with mean time between failures (MTBF) exceeding 25,000 hours based on component reliability modeling.
Is calibration certification included with shipment?

A factory-issued Certificate of Conformance (CoC) is standard. NIST-traceable calibration certificates with as-found/as-left data are available as an optional service—performed using accredited third-party laboratories.
