BOXUN SPX-100B-Z Biochemical Incubator

Overview

The BOXUN SPX-100B-Z Biochemical Incubator is a precision-engineered, microprocessor-controlled environmental chamber designed for stable, long-term cultivation and maintenance of biological samples under tightly regulated thermal conditions. Based on resistive heating and forced-air convection principles, the unit maintains uniform temperature distribution across its interior chamber—critical for reproducible microbial growth, enzymatic assays, BOD determination, fungal propagation, and plant tissue culture. Its operational range of 5–50 °C accommodates a broad spectrum of biochemical protocols, including mesophilic bacterial incubation (e.g., E. coli at 37 °C), psychrotrophic studies (down to 5 °C), and thermotolerant strain maintenance. Constructed with a cold-rolled steel exterior finished in electrostatic epoxy coating and a mirror-polished 304 stainless-steel inner chamber, the SPX-100B-Z ensures corrosion resistance, ease of decontamination, and compliance with GLP-aligned laboratory hygiene standards.

Key Features

• Microcontroller-based PID temperature control system delivering ±0.5 °C fluctuation and ±1 °C uniformity (measured at 37 °C), validated per ISO 17025 traceable calibration practices
• High-brightness dual-digit LED display showing real-time setpoint and actual chamber temperature with 0.1 °C resolution
• Tactile membrane keypad interface supporting intuitive parameter entry for temperature, timer duration, and hold mode activation
• Two independently adjustable, load-rated stainless-steel shelves (included), enabling flexible vertical configuration for flasks, Petri dishes, or multi-well plates
• Integrated interior LED lighting and large-view, vacuum-insulated tempered glass door—optimized for non-intrusive sample monitoring without thermal disturbance
• Power-failure recovery function: automatically restores pre-interruption settings—including temperature setpoint, elapsed time, and timer status—upon mains restoration
• Energy-efficient 300 W heating system with overtemperature cut-off protection and thermal fuse redundancy

Sample Compatibility & Compliance

The SPX-100B-Z supports standard life science consumables, including glass and polystyrene culture vessels (up to 500 mL Erlenmeyer flasks), agar plates, slants, and suspension cultures. Its chamber geometry (450 × 380 × 585 mm) permits simultaneous handling of ≥24 standard Petri dishes or six 100 mL tissue culture flasks. The unit meets essential safety and electromagnetic compatibility requirements per GB/T 14710 (Chinese national standard for environmental testing of medical electrical equipment) and conforms to IEC 61000-4 series immunity specifications. While not certified for ISO Class 5 cleanroom integration, its sealed construction and smooth internal surfaces support routine disinfection using 70% ethanol or hydrogen peroxide vapor—making it suitable for BSL-1 and BSL-2 compatible workflows in academic, pharmaceutical QC, and environmental testing labs.

Software & Data Management

This model operates as a standalone hardware platform with no embedded data logging or network connectivity. All operational parameters are configured locally via front-panel controls; no proprietary software, drivers, or cloud services are required. However, the robust parameter memory architecture—including retention of user-defined setpoints and timer states through power cycles—ensures continuity during routine lab operations and aligns with ALCOA+ principles for basic data integrity. For laboratories requiring audit trails or electronic records, external USB data loggers (e.g., compliant with FDA 21 CFR Part 11 when paired with validated software) may be deployed alongside the unit to capture temperature history at user-defined intervals.

Applications

• Biochemical oxygen demand (BOD₅) analysis per APHA Standard Methods 5210B and ISO 5815-1
• Cultivation of aerobic and facultative anaerobic bacteria (e.g., Salmonella, Staphylococcus aureus) for food, water, and clinical microbiology
• Mycological studies involving molds and yeasts (e.g., Aspergillus, Candida albicans) under controlled humidity-adjacent conditions
• Seed germination trials, callus induction, and micropropagation in plant biotechnology research
• Enzyme activity assays requiring precise thermal stabilization prior to spectrophotometric or HPLC analysis
• Storage and acclimatization of reference strains in QC/QA departments adhering to USP & EP microbiological guidelines

FAQ

Does the SPX-100B-Z include humidity control?

No. This is a dry-air, temperature-only incubator. Humidity regulation requires auxiliary equipment such as external humidifiers or dedicated CO₂/humidity incubators.
Is the unit suitable for GMP-regulated environments?

It can be deployed in GMP settings for non-critical applications (e.g., media preparation warming, backup strain storage); however, formal qualification (IQ/OQ/PQ) must be performed by the end user per Annex 15 and internal SOPs.
Can the shelves support heavy glassware loads?

Each shelf is rated for static loads up to 15 kg; avoid stacking tall or top-heavy vessels to maintain airflow integrity and thermal homogeneity.
What is the recommended calibration frequency?

Annual verification against NIST-traceable reference thermometers is advised, with additional checks after relocation, repair, or observed performance deviation.
Is service documentation available in English?

Yes—technical manuals, wiring diagrams, and spare parts lists are provided in bilingual (Chinese/English) format upon request from BOXUN’s international support team.
