A hypoxia chamber is a sealed workstation that allows researchers to culture cells and tissues in environments with precisely controlled oxygen, carbon dioxide, nitrogen, temperature, and humidity levels. Unlike standard incubators, which typically provide normoxic conditions (≈21% oxygen), hypoxia chambers enable simulation of low-oxygen atmospheres ranging from near anoxia (0%) up to physiological levels (1–5%).
These chambers are indispensable for studies in:
- Cancer biology – tumor cells often thrive in hypoxic conditions.
- Stem cell research – low O₂ supports proliferation and differentiation.
- Tissue engineering – simulating in vivo environments.
- Pharmacology and drug discovery – evaluating drug responses under hypoxia.
HW400 Hypoxia Workstation: Overview
The HW400 Hypoxia Workstation is designed to create a stable, controlled, and low O₂ environment for laboratory research. Its large 400 Petri dish incubation capacity makes it ideal for high-throughput laboratories, academic institutions, and pharmaceutical companies engaged in intensive cell culture research.
Key highlights include:
- Incubation capacity: 400 Petri dishes.
- Interlock capacity: 60 Petri dishes + single dish entry.
- Compact footprint: W1300 × D700 × H700 mm.
- Temperature control: Ambient +4 °C to 42 °C with ±0.5 °C stability at 37 °C.
- Gas control: O₂ in 0.5% increments (up to 20%), CO₂ in 1% increments (up to 20%), N₂ derived from both.
- Weight: Net 70 kg, Gross 203 kg.
Advanced Gas Control System
The heart of the HW400 is its precise gas regulation technology. Researchers can fine-tune oxygen and carbon dioxide concentrations with small increments (O₂: 0.5%, CO₂: 1%), ensuring an accurate simulation of in vivo conditions.
This capability allows the chamber to replicate diverse physiological or pathological states, whether hypoxia, hypercapnia, or controlled nitrogen flushing. The advanced gas system also ensures rapid stabilization, minimizing experiment downtime and reducing gas consumption costs.
Glove-Free Operation
Unlike traditional glove-based hypoxia chambers, the HW400 features an innovative bare-hand entry system:
- Air-tight wrist seals replace bulky gloves.
- Provides greater dexterity and comfort for researchers.
- Eliminates internal port bungs, freeing up workspace inside the chamber.
- Maintains the low-oxygen atmosphere without compromise.
This design results in easier sample handling, more comfortable operation, and improved efficiency.
Large Interlock System
A unique feature of the HW400 is its large interlock chamber capable of holding 60 Petri dishes. This two-door system minimizes oxygen disturbance:
- The outer door reduces overall chamber length.
- The inner sliding door ensures smooth transfer without compromising internal conditions.
- Both doors are equipped with wear-resistant seals for long-term reliability.
For smaller transfers, a single-plate entry system is available, allowing quick insertion of individual dishes.
Temperature Control and Stability
Temperature is one of the most critical factors for cell growth. The HW400 ensures precise and stable thermal conditions:
- Range: Ambient +4 °C to 42 °C.
- Stability: ±0.5 °C at 37 °C.
- Uniform heating ensures consistent cell culture results across all samples.
The integrated system provides dependable long-term operation, essential for time-sensitive experiments.
Energy Efficiency and Safety
The HW400 is engineered with economy and safety in mind:
- Low gas consumption, reducing running costs.
- Complies with international laboratory safety standards.
- Easy to maintain, service, and clean.
Its robust design ensures long operational life, making it a cost-effective investment for laboratories.
