Introduction: The "Tale of Two Technologies" in Incubation

In microbiology, strain preservation, and fermentation experiments, Temperature Uniformity and Fluctuation are not just specifications—they are the dividing line between a successful culture and a failed experiment.

The Labonce Thermostat Incubator family offers two distinct technological paths to achieve thermal control:

1. The Labonce-GHP Series (Water-jacket): The traditional "King of Stability," utilizing the high specific heat capacity of water.

2. The Labonce-DHP Series (Electric/Air-jacket): The modern "Efficiency Expert," utilizing direct heating for rapid response.

While both series share an identical premium exterior—featuring mirror stainless steel liners and double-door designs—their core performance metrics differ significantly. This guide uses strict product data to analyze the boundaries of each technology.

1. The Labonce-GHP Series: The Philosophy of "Steady State"

The Water-jacket technology focuses on thermal inertia. The Labonce-GHP series features a water-filled jacket surrounding the inner chamber, heating the samples indirectly through the water's thermal mass.

Core Data Advantages:

According to the technical parameters, the GHP series demonstrates superior stability:

• Temperature Uniformity: ±0.5℃ (@37℃).

  • Expert Insight: This minimal variance across the chamber makes it the ideal choice for highly temperature-sensitive Storage Strains and precise Biological Cultures.

• Temperature Fluctuation: ±0.3℃.

  • Expert Insight: Once the set temperature is reached, the water jacket acts as a buffer against external ambient temperature changes. Even in the event of a power outage, the GHP series retains heat significantly longer than electric models, protecting valuable samples.

Structural Features:

• Heating Method: Uses "Watertight heating", ensuring gentle heat transfer with absolutely no "Hot Spots" that could scorch samples close to the walls.

• Inner Design: Features four corners with a half-circle arc design, combined with free-loading shelves, ensuring the water jacket covers the maximum surface area while remaining easy to clean.

2. The Labonce-DHP Series: The Power of "Dynamic Efficiency"

The Electric Thermostat (Air-jacket) technology drives efficiency. The Labonce-DHP series utilizes heating elements to directly heat the air or the air jacket surrounding the chamber.

Core Data Advantages:

• Heating Speed: The product data explicitly highlights its "Fast heating speed".

  • Application: For labs that require frequent door openings (causing temperature loss) or need to rapidly cycle to high temperatures (e.g., up to 65℃), the DHP recovers its set point much faster than the GHP series.

• Temperature Uniformity: ±1.0℃ (@37℃).

  • Comparison: While slightly less precise than the GHP’s ±0.5℃, this precision fully complies with the YY 0027-1990 industry standard for electrothermal incubators, making it perfectly adequate for routine bacterial culture.

• Control Precision: It maintains a high Temperature Resolution of 0.1℃, ensuring accurate set-point management.

3. Rigorous Selection Matrix: Data-Driven Decision Making

To visualize the differences, we have extracted the key parameters for a side-by-side comparison:

4. Shared Labonce DNA: Safety & Compliance

Regardless of the heating technology, the Labonce ecosystem ensures that "Performance" never comes at the cost of "Compliance." Both the GHP and DHP series feature standard GLP/GMP configurations:

1. Double Door Design:

   To solve the issue of temperature fluctuations during observation, both series utilize an "External door with built-in glass doors." This allows researchers to clearly observe culture changes without breaching the internal environment.

2. Data Integrity Ready:

   Both series offer the optional Model WHI/HI Touch Screen Controller. This upgrade provides Three-level permissions and Audit Tracking, essential for pharmaceutical companies requiring FDA 21 CFR Part 11 compliance.

3. Material Excellence:

   Both utilize a Mirror Stainless Steel liner. This material is a non-pollution source, easy to clean, and resistant to corrosion—critical for preventing cross-contamination in shared labs.

Conclusion: Prioritizing Precision vs. Efficiency

The final selection logic reduces to a single question: How sensitive are your samples to temperature variance?

• Select the Labonce-GHP (Water-Jacket) if: You are working with precious strain libraries, mammalian cells, or long-term cultures where a 0.5℃ variance could impact viability. It offers "water-bath" levels of protection.

• Select the Labonce-DHP (Electric) if: You are performing routine bacterial plating, fermentation research, or have a workflow that involves frequent door openings. It is the cost-effective, high-efficiency choice for high-throughput labs.
