Sedimentation Rate Tubes for Water and Wastewater Testing
Sedimentation rate tubes, commonly supplied as Imhoff sedimentation cones or sedimentation vessels, are used to observe and measure particles that settle out of liquid samples over time. These products are especially useful in wastewater treatment, environmental monitoring, well water testing and laboratory settling studies where the volume of settled material needs to be read from a graduated vessel.
- Imhoff Cone Options: Choose graduated Imhoff cones for measuring settleable solids in water, wastewater and sample settling applications.
- Glass and Plastic Formats: Select DURAN glass, SAN plastic or polycarbonate sedimentation vessels based on durability, visibility and handling requirements.
- Stopcock Choices: Use cones with stopcocks where controlled draining is required, or without stopcock for simpler sedimentation observation.
- Graduated Measurement: Visible products include graduated formats up to 100 ml and 1000 ml for reading settled particle volume.
How to Choose Sedimentation Rate Tubes and Imhoff Cones
Selection should begin with the sample type, capacity requirement, material preference and whether a drainable stopcock is needed. Glass cones can provide excellent clarity and chemical resistance for controlled laboratory use, while SAN or polycarbonate formats may suit practical wastewater, field or teaching workflows where lighter handling and impact resistance are useful.
- Capacity: Match the cone or vessel capacity to the sample volume and the expected amount of settleable material.
- Material: Choose borosilicate or DURAN glass for clarity and chemical resistance, or SAN and polycarbonate options for lightweight handling.
- Drainage: Consider a stopcock or screw-cap base when easy draining, cleaning or sample removal is required.
- Application: Match the product to wastewater testing, well water sand content checks, environmental monitoring, QC testing or teaching labs.

Frequently Asked Questions
What are sedimentation rate tubes used for?
They are used to observe and measure particles that settle from liquid samples, commonly in wastewater testing, well water analysis, environmental monitoring and laboratory sedimentation studies.
Are Imhoff cones the same as sedimentation cones?
Imhoff cones are a common type of sedimentation cone used to measure settleable solids in water and wastewater samples using a graduated cone shape.
Should I choose a sedimentation cone with or without a stopcock?
Choose a stopcock version when controlled draining or easier sample removal is useful. A cone without stopcock may suit basic settling observation and routine sedimentation measurement.
