Sedimentation Rate Tubes for New Zealand Water Testing Workflows
Sedimentation rate tubes, Imhoff cones and sedimentation vessels are used to hold liquid samples while particles settle to the bottom over a defined period. The settled volume can then be read from the graduation, supporting wastewater monitoring, environmental assessment, well water sand content checks and general laboratory sedimentation work.
- Water and Wastewater Testing: Use sedimentation cones to assess settleable solids and particle settling in liquid samples.
- Material Options: Choose from visible DURAN glass, SAN plastic and transparent polycarbonate sedimentation vessels depending on the workflow.
- Graduated Reading: Select 100 ml or 1000 ml graduated formats where clear volume reading is required.
- Drainage Options: Choose with-stopcock or without-stopcock formats based on cleaning, draining and handling needs.
How to Select Sedimentation Rate Tubes and Imhoff Cones
Start by reviewing the sample volume, expected solids level, material preference and whether the cone needs a drain outlet. Wastewater and environmental teams may prioritise 1000 ml Imhoff cone formats, while laboratories and teaching facilities may choose glass or plastic vessels based on clarity, durability and daily handling requirements.
- Sample Volume: Match the cone capacity to the volume needed for the test method or internal procedure.
- Vessel Material: Use glass for clarity and chemical resistance, or plastic formats where lighter handling and impact resistance are important.
- Cleaning: Consider stopcock or screw-cap designs where draining and cleaning efficiency matter.
- Workflow Fit: Match the vessel to wastewater testing, environmental sampling, laboratory QC, education or research use.

Frequently Asked Questions
What is an Imhoff sedimentation cone used for?
An Imhoff sedimentation cone is used to measure settleable solids in water, wastewater and similar liquid samples by allowing particles to settle and reading the volume from the graduated cone.
Which material is better for sedimentation cones?
Glass is often selected for clarity and chemical resistance, while SAN plastic or polycarbonate formats may be preferred for lighter handling or routine use.
Can John Morris Group help choose the right sedimentation vessel?
Yes, the New Zealand team can help review sample type, required capacity, material preference and stopcock requirements before selecting a suitable sedimentation vessel.
