Shanghai Dengsheng Instrument Manufacturing Co., Ltd. designs and builds the Incubator Series as a complete family of controlled-environment chambers for life science, pharmaceutical, food safety, and agricultural research. As an Incubator Series manufacturer, we produce electric heating, water-jacketed, biochemical, mold, CO₂, low-temperature, illuminated, and artificial climate incubators in our 8,000 m² facility, supported by 23 national patents and ISO-9001 quality management certification.
Our incubators maintain stable temperature, humidity, gas concentration, and light conditions for cell culture, microbial growth, seed germination, and stability testing. We configure each unit around the customer's working temperature, chamber volume, and control requirements, and we support the complete project from specification through installation guidance.
Our Incubator Series covers nine distinct chamber types, each engineered for a specific application profile. The table below summarizes the range and typical use cases.
| Incubator Type | Temperature Range | Volume Range | Key Feature |
|---|---|---|---|
| Electric Heating (DHP) | RT+5 to 65°C | 16–270 L | Forced air circulation, LCD control |
| Water-jacketed (GHP) | RT+5 to 65°C | 50–270 L | Indirect heating, temperature retention |
| Biochemical (BIC) | 5 to 65°C | 72–500 L | Compressor cooling, ±1°C uniformity |
| Mold Incubator | — | — | Corrosion-resistant, double-door design |
| CO₂ Incubator | — | — | Stainless steel liner, gas control |
| Low Temperature | — | — | Fast cooling, low-noise operation |
| Illuminated | — | — | Light control, good sealing |
| Artificial Climate | — | — | Light, humidity, temperature simulation |
| Anaerobic | — | — | High-precision constant temperature |
For detailed specifications on the electric heating, water-jacketed, and biochemical models, see the individual product pages. We also manufacture the related Drying Oven Series and Vacuum Box Series for complementary laboratory workflows.
The Incubator Series serves four primary industry segments, each with distinct environmental control requirements.
Every incubator in the series shares a common construction philosophy: durable materials, cleanable surfaces, and thermal efficiency.
Our control systems are built around microcomputer PID intelligent temperature control with self-tuning functionality. The 5.7-inch LCD display shows constant temperature time, operating temperature, set temperature, heating status, and over-temperature alarms on a single screen.
For low-temperature models, we use fluorine-free environmentally friendly compressors with low noise and high energy efficiency. The modular refrigeration system ensures stable long-term operation.
We enforce a 4-stage inspection protocol across all incubator production: incoming material inspection, in-process inspection, aging test, and final pre-shipment check. Our testing laboratory uses precision instruments to quantitatively verify temperature uniformity and fluctuation.
We perform multi-point chamber mapping to validate temperature uniformity under both empty and fully loaded conditions. This ensures that practical use aligns with calibrated performance values. Our ISO-9001 quality management system, certified since 2019, governs the entire process from design to inspection.
We offer strong non-standard customization capabilities. Customers can provide specific requirements such as temperature range, chamber size, material (e.g., stainless steel), and special functions like programmed temperature control, remote monitoring, or nitrogen atmosphere. Our R&D team develops products according to drawings, samples, or specific working conditions.
For international customers, we provide English technical documentation, assistance with international logistics and customs clearance, and remote installation guidance via online video conferencing. Standard models typically ship within 5–7 business days after payment; customized products have delivery dates negotiated and written into the contract.
To prepare an accurate configuration and quotation, we need the following project information:
Electric heating and water-jacketed models operate from RT+5 to 65°C. Biochemical incubators operate from 5 to 65°C with compressor cooling. Low-temperature models provide fast cooling for applications below ambient. We can customize temperature ranges for specific applications.
Yes. We provide non-standard customization based on your drawings, samples, or working conditions. Our R&D team can adjust chamber dimensions, material grade, shelf configuration, and control features to match your process requirements.
Electric heating models use forced air circulation with silicone heating elements for rapid temperature response. Water-jacketed models use indirect heating through a water jacket, providing better temperature uniformity and longer temperature retention after power failure. Choose water-jacketed for temperature-sensitive applications.
We perform multi-point chamber mapping under both empty and fully loaded conditions using precision instruments. Temperature uniformity is verified at 37°C for standard models, with typical values of ±1.5°C for electric heating and water-jacketed models, and ±1°C for biochemical models.
We provide English instruction manuals, power supplies meeting international standards, and certification services. We assist with international logistics and customs clearance, and offer remote installation guidance and troubleshooting via online video conferencing.
Our portfolio also includes Products for applications with different operating ranges, interfaces or integration requirements.
