I'm interested in exploring turbidity tubes and other ways to monitor for turbidity. Does anyone have resources for this?

If you are looking for 1 cm x 1 cm cuvettes , they should be transparent on all four sides. This way, they can be used for both turbidimeters and the spectrometers. Then the question is what plastic (solvent resistance) the cuvettes are made of and cost. I have seen weird setups for turbidimeters where round sample vials are used. The light is fed from the bottom and the turbidity is sampled from the side.


Are cuvettes standard for turbidity? We actually stock them in the Kits store, so that'd be convenient.

I've seen a bunch of different things used, but cuvette s are most common.


Neat do you know where I could find some methods to do this written out?

Google " epa method 180.1 determination of turbidity... ". It's dated August of 1993. Should get you started.

Here are neat instructions on constructing a turbidity tube by Elizabeth Myre & Ryan Shaw:: http://www.virginia.edu/blandy/blandy_web/education/Bay/TurbidityTubeConstruction&Use_Myre_Shaw.pdf GLOBE also has a turbidity tube construction notes here: https://www.gvsu.edu/wri/education/instructors-manual-turbidity-10.htm I've also posted a new question here on the tube method verses other methods for observing turbidity.
