Project: Design a Purification Process

Use household items to purify water that contains macroscopic and microscopic contaminants. Successfully purified water has a clear colorless appearance, acceptable odor with no suspended solids, total dissolved solids below 900 mg/L, turbidity below 150 NTU, and conductivity below 500 µS/cm.

Featured Equipment

Colorimeter and Turbidity

Wireless Colorimeter & Turbidity Sensor

This sensor can function as a turbidimeter or colorimeter and is capable of measuring absorbance and transmittance at six different wavelengths.

Conductivity Sensor

Wireless Conductivity Sensor

This waterproof sensor connects via Bluetooth® to measure both conductivity (ionic content in solution) and total dissolved solids.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
