Introduction: Precision in Environmental & Microbial Analysis

In scientific research fields such as environmental protection, health epidemic prevention, and aquatic product testing, the incubation environment is critical. Two commonly confused equipment types are the Biochemical Incubator and the Mold Incubator.

While they share a foundation in constant temperature control, their applications diverge significantly based on specific parameter capabilities. According to GB/T 28851-2012 (Technical conditions for biochemical incubators), selecting the wrong equipment can lead to compromised culture results.

This guide utilizes strict technical data from the Labonce-BI and Labonce-MI/MIS series to establish a rigorous selection logic.

1. Functional Logic: Defining the Core Application

The first step in selection is defining the biological target.

• Labonce-BI Series (Biochemical):

  Engineered primarily for BOD (Biochemical Oxygen Demand) detection and water analysis. Its core function facilitates the incubation of bacteria and storage of strains where humidity control is not the primary variable.

• Labonce-MI/MIS Series (Mold):

  Designed specifically for the cultivation of eukaryotic microorganisms like molds and fungi. Because fungal growth is highly sensitive to moisture, this series (specifically the MIS model) integrates humidity parameters to prevent culture desiccation.

2. Rigorous Parameter Comparison

To make an informed decision, we must analyze the data differences in Temperature, Humidity, and Configuration.

A. Temperature Control Range

Both series utilize imported fully enclosed industrial compressors to achieve low-temperature operation, but their effective ranges differ based on the model configuration.

• Wide Range (0 ~ 60℃):

  Found in the Labonce-BI Series and standard Labonce-MI Series. This wide span accommodates both low-temperature preservation (+5℃) and standard incubation (37℃/60℃).

• Restricted Range (15 ~ 50℃):

  Found in the Labonce-MIS Series.

  • Logic: The MIS series includes a humidity control system. Extreme temperatures (too low or too high) can compromise the accuracy of the humidity sensor or cause condensation issues, necessitating a narrower operational window.

B. The Humidity Variable (The Deciding Factor)

This is the most critical technical distinction found in the product data tables.

• Labonce-BI / Standard MI:

  These units do not have active humidity control. Humidity is a byproduct of the temperature setting.

• Labonce-MIS Series:

  Features a dedicated Humidity Control System.

  • Range: 50 ~ 85% RH.

  • Precision: Humidity Fluctuation ±5% RH.

  • Application: Essential for long-term mold cultivation where maintaining medium moisture is vital to prevent agar plates from drying out.

C. Sterilization Configuration

Biological safety and cross-contamination prevention are handled differently across the series.

• Labonce-MI/MIS Series:

  UV disinfection lights are listed as part of the "Other configuration," making them a standard feature for mold incubators to periodically sterilize the chamber between fungal growth cycles.

• Labonce-BI Series:

  The UV sterilization system is listed as an "Optional" feature. Standard BOD testing typically involves sealed bottles, making ambient sterilization less critical unless specified by the user.

3. Shared Technological DNA

Despite their differences, both series share the robust construction standards of the Labonce platform, ensuring data integrity and durability.

• Air-Way System: Both adopt a brand-new air-way structural design that ensures temperature uniformity (≤2.0℃ @37℃) across different parts of the chamber.

• Material Science: The liners are constructed from mirror stainless steel 304, ensuring a pollution-free source that is easy to clean.

• Data Management: Both series support needle-type micro printers and electronic data storage with U-disk export, ensuring compliance with laboratory data recording standards.

Based on the technical data extracted above, use this matrix to finalize your selection:

Conclusion

The choice between a Biochemical and a Mold Incubator is not just about temperature—it is about humidity management and sterilization needs.

For standard water analysis and bacterial work, the Labonce-BI Series offers the compliant precision you need. However, for rigorous mycology applications where moisture is a growth factor, the Labonce-MIS Series is the only scientifically valid choice.
