Overview
The DRETOP ZDP-9162 Electric Constant Temperature Incubator is a precision-engineered laboratory incubation system designed for stable, repeatable thermal environments in life science applications. It operates on the principle of direct resistive heating via embedded electric heating elements distributed uniformly along the inner chamber walls, combined with natural convection air circulation to maintain uniform thermal distribution without mechanical fans—minimizing vibration and contamination risk. This architecture makes it especially suitable for non-agitated, static culture protocols including bacterial colony propagation, fungal growth studies, enzyme activity assays, and long-term stability testing of biological reagents. Its temperature range (RT + 2°C to 65°C) covers standard microbiological incubation (e.g., 37°C human pathogen culture, 25–30°C environmental isolates), as well as higher-temperature applications such as mycological incubation or accelerated aging tests. The unit complies with general design principles aligned with ISO 13485-informed manufacturing practices and supports GLP-compliant workflows through configurable alarm thresholds and power-failure recovery logic.
Key Features
- Stainless steel interior chamber with removable, height-adjustable stainless steel shelves—enabling full accessibility for cleaning, autoclaving, and sterilization validation.
- Double-door observation window: outer magnetic seal door with high-efficiency thermal insulation; inner tempered glass door—reducing condensation and maintaining visual clarity during extended operation.
- Digital PID temperature controller with large backlit LCD display—showing real-time setpoint, actual temperature, and elapsed time simultaneously; resolution: 0.1°C.
- Intelligent heating management: self-regulating power modulation adjusts heating output dynamically during ramp-up and steady-state phases to prevent overshoot and ensure thermal stability.
- Corner-rounded internal geometry and electrostatically coated exterior housing—enhancing structural integrity, corrosion resistance, and ease of decontamination.
- Integrated safety functions: programmable over-temperature alarm, automatic restart after power interruption, and non-volatile parameter memory retention.
Sample Compatibility & Compliance
The ZDP-9162 accommodates standard Petri dishes (up to 150 mm), multi-well plates (6–96-well), culture flasks (T25–T225), and test tubes—all without requiring forced-air agitation. Its natural convection design eliminates airflow-induced desiccation, preserving media moisture integrity during prolonged incubation. The unit meets fundamental electrical safety requirements per IEC 61010-1 and is constructed to support routine cleaning with 70% ethanol, isopropyl alcohol, or hydrogen peroxide vapor (HPV) decontamination cycles. While not certified for ISO Class 5 cleanroom integration, its sealed chamber and smooth interior surfaces facilitate compliance with CLSI M22-A3 and USP environmental monitoring guidelines when deployed in controlled laboratory spaces.
Software & Data Management
The ZDP-9162 operates as a standalone instrument with no embedded data logging capability by default. Optional RS485 serial interface enables connection to external SCADA systems or centralized lab monitoring platforms for remote status polling (temperature, alarm state, runtime). An optional external micro-printer can record timestamped temperature readings at user-defined intervals. For regulated environments, the unit supports audit-ready documentation when paired with independent temperature mapping validation reports (per ASTM E2874 or ISO/IEC 17025-accredited protocols). Though lacking native 21 CFR Part 11-compliant electronic signatures, its deterministic control logic and hardware-based alarm triggers provide traceable operational evidence suitable for GMP-aligned process verification.
Applications
- Bacterial and yeast cultivation in academic and clinical microbiology labs.
- Cell line maintenance for non-suspension adherent cultures where mechanical agitation is contraindicated.
- Enzyme kinetics and protein stability studies requiring precise, low-vibration thermal conditions.
- Seed germination and plant tissue culture under defined ambient temperature regimes.
- Pharmaceutical excipient stability testing per ICH Q1A(R2) guidance (long-term and accelerated conditions).
- Educational use in undergraduate biology and biotechnology laboratories for foundational incubation experiments.
FAQ
What is the maximum operating temperature of the ZDP-9162?
The unit is rated for continuous operation up to 65°C, with optimal stability and uniformity validated at 37°C.
Does this incubator include humidity control?
No—this is a dry-air, non-humidified incubator. Humidity-sensitive applications require supplemental humidification chambers or alternative models with integrated steam generators.
Can the ZDP-9162 be used for CO₂-dependent cell culture?
No—this model lacks gas inlet ports, CO₂ sensors, or pH-controlled feedback mechanisms required for mammalian cell culture.
Is calibration certificate included with shipment?
Factory calibration is performed prior to dispatch; however, an accredited NIST-traceable calibration certificate is available as an optional add-on upon request.
What is the warranty coverage?
DRETOP provides a standard 12-month parts-and-labor warranty covering manufacturing defects, excluding consumables and damage from improper handling or unauthorized modification.
