HEPES

Maintain precise pH control in biological research with HEPES buffer, a trusted Good’s buffer for physiological conditions. With a pKa of 7.5 at 25°C, HEPES effectively buffers in the pH range of 6.8 to 8.2, making it an excellent choice for cell culture, enzyme assays, and protein purification—especially when CO₂-based buffering systems are unsuitable.

• Strong pH stability for reliable experimental conditions
• Resistant to degradation under various environmental conditions
• Minimal metal ion interaction ensures compatibility with sensitive biological systems

Due to its chemical stability and non-toxic properties, HEPES buffer is ideal for long-term cell culture studies, biochemical assays, and applications requiring precise pH maintenance without CO₂ buffering.
