Does anyone know what the box is called where you put the liquid that you want testing into? Thanks - it's called a cuvette

colorimeters do not select wavelength, merely a coloured slide that coveres a range of wavelengths, wave length selection is done on a spectrophotometer

how do u select a particular wave lenth in a colorimetr

apparently, the highest a reading can go on a colorimeter in the absorbance setting is 1.00, i.e. all the light is absorbed. however, during my experiments, i managed to smehow attain results of oer 1.00, e.g. 1.72, etc i have heard now, in contrast to what i initially thought, that colorimeters can go up to a reading of 2.00. i would be glad if someone could let me know what this reading shows, and if it is possible?

Sounds like you are talking about absorbance units.
