19-BAS-031 Hach BioTector Sample Overflow Chamber

The Sample Overflow Chamber (Product Number: 19-BAS-031) is a modular accessory specifically engineered for the BioTector B3500 and B7000 series analyzers. Its primary function is to manage the incoming sample flow by providing a "constant head" of liquid. As the process sample enters the chamber, any excess volume is directed through an overflow port, while the analyzer’s sampling pump draws from a stable, non-pressurized reservoir. This design is particularly effective for samples containing high levels of particulates or fats, as the chamber’s geometry helps to keep solids in suspension, preventing sedimentation that could lead to unrepresentative readings or system blockages. Constructed from chemically resistant materials, it is built to withstand the aggressive industrial environments where BioTector systems are typically deployed.

Advantages

• Stable Sample Delivery: Provides a pressure-free sample source, protecting the analyzer’s internal pump and ensuring highly repeatable dosing volumes.
• Representative Sampling: The overflow design ensures a continuous "fresh" sample is always available, minimizing lag time and accurately reflecting current process conditions.
• Particulate Management: Helps maintain solids in suspension, making it ideal for wastewater and industrial process streams with high turbidity.
• Reduced Maintenance: Acts as a primary settling point for heavy debris, which can be easily cleaned, thereby protecting more sensitive downstream components.
• Simple Integration: Features standard inlet, outlet, and overflow connections for easy installation into existing BioTector cabinet configurations.
• Corrosion Resistant: Built from high-quality, durable materials that are compatible with a wide range of industrial reagents and wastewater chemistries.
