Otisience MH-2800E Multi-Function Constant-Temperature Incubator

Overview

The Otisience MH-2800E Multi-Function Constant-Temperature Incubator is an engineered thermal platform designed for precise, repeatable temperature control in analytical and preparatory laboratory workflows. Unlike general-purpose ovens or dry baths, the MH-2800E employs a PID-regulated resistive heating system coupled with high-efficiency thermal insulation and forced-air-free convection architecture—ensuring uniform heat distribution across the chamber without introducing mechanical vibration or airflow-induced sample disturbance. Its operational range spans from ambient +5°C to 200°C, making it suitable for applications requiring controlled thermal activation, enzyme inactivation, solvent evaporation, reagent pre-warming, or stabilization of temperature-sensitive reaction mixtures. The unit complies with fundamental safety and electromagnetic compatibility requirements per IEC 61010-1:2010 for laboratory electrical equipment, and its construction meets material flammability Class HB standards per UL 94.

Key Features

• PID-based digital temperature control with dual 4-digit LED display showing both setpoint and real-time chamber temperature—enabling immediate visual verification of thermal deviation during operation.
• High-stability thermal regulation: ±0.1°C stability under steady-state conditions and ±0.15°C accuracy across the full operating range, validated using NIST-traceable reference thermometers.
• Dual independent timer functionality: simultaneous display of programmable countdown duration and elapsed runtime—critical for protocol adherence in time-dependent incubation, denaturation, or drying steps.
• Redundant safety architecture including fixed upper-limit cutoff at 200°C and dynamic deviation alarm triggered when internal temperature exceeds setpoint by +5°C—both functions are hardware-latched and non-bypassable.
• Modular heating block interface accommodating two standard-height aluminum blocks (e.g., for 0.2–2.0 mL tube formats) or one double-height block—facilitating parallel processing of diverse sample containers without cross-contamination risk.
• Compact footprint (240 × 92 × 215 mm external) optimized for benchtop integration in QC labs, HPLC prep areas, or teaching laboratories where spatial efficiency is constrained.

Sample Compatibility & Compliance

The MH-2800E supports a broad range of sample vessels—including microcentrifuge tubes, PCR strips, glass vials, and custom aluminum heating blocks—provided they remain within dimensional limits (max height: 51 mm chamber depth). It is routinely deployed in environments governed by ISO/IEC 17025:2017 (General Requirements for the Competence of Testing and Calibration Laboratories), where documented thermal performance validation is required. While not certified for medical device sterilization (i.e., does not meet ISO 17665 or EN 285), its thermal repeatability supports GLP-compliant method development for dissolution testing, stability studies per ICH Q1A(R3), and extraction protocol standardization. No volatile organic solvent exposure beyond manufacturer-specified limits is permitted; operation in fume hoods is recommended when handling low-boiling-point solvents.

Software & Data Management

The MH-2800E operates as a standalone analog-digital hybrid instrument with no embedded firmware upgrade path or PC connectivity. All parameter inputs and status monitoring occur via front-panel membrane keys and LED indicators. For auditability in regulated environments, users are advised to integrate external data loggers (e.g., compliant with FDA 21 CFR Part 11 when paired with appropriate software validation packages) to record time-stamped temperature traces. The dual-timer function supports manual SOP documentation by enabling direct correlation between elapsed time and procedural milestones—reducing transcription errors during batch record generation.

Applications

• Pre-incubation of enzymatic reaction mixtures prior to kinetic assay initiation.
• Controlled drying of thin-layer chromatography plates or solid-phase extraction cartridges.
• Thermal equilibration of mobile phase reservoirs in HPLC systems to minimize baseline drift.
• Activation of temperature-sensitive catalysts or initiators in synthetic chemistry workflows.
• Stabilization of calibration standards during gravimetric preparation or volumetric dilution sequences.
• Supporting ASTM D5296 (gel permeation chromatography) and USP (chromatography) protocols requiring column oven or sample tray temperature control.

FAQ

Does the MH-2800E support RS-232 or USB communication?
No. It is a manually operated, non-networked instrument with no digital interface ports.
Can the unit be used for sterilization or autoclaving procedures?
No. It lacks steam generation, pressure control, or validation-grade temperature mapping capability required for sterilization cycles.
Is calibration certificate included with shipment?
A factory calibration report (non-NIST-traceable) is provided; users must perform periodic in-house verification per their quality management system requirements.
What is the maximum load weight the chamber can accommodate?
The aluminum heating base is rated for ≤1.2 kg total mass—including blocks, tubes, and samples—to maintain thermal uniformity and prevent heater overload.
Are replacement heating blocks available for custom tube formats?
Yes. Otisience offers OEM-machined blocks for common configurations (e.g., 96-well PCR, 15/50 mL conical); custom designs require minimum order quantities and lead-time confirmation.
