Introduction

♦ The TW1009 colorimeter is used to measure the transmittance of the solution and the reaction rate of chemical reactions with color or transparency in the reaction process.


Usage

♦  The colorimeter is directly connected to the computer with USB line before being used. When it is used for the first time, if the numerical deviation is large, it can be reset.

♦  The colorimeter is connected to the computer after boot. Click the colorimeter button to adjust the wavelength of different wavelengths: red, violet, blue and green.

♦  Every time we use the colorimeter, we need to wash the colorimetric dish with distilled water and wipe the water stains with absorbent paper.

♦  Low power reminding: USB power is not inserted and when the battery is low, the word “Lo” will flicker on the screen; USB power is inserted, no matter whether the battery is low or not.


Notes

♦  When the first time is used, if the numerical deviation is large, the reset operation can be done.

♦  Every time we use the colorimeter, we need to wash the colorimetric dish with distilled water and wipe the water stains with absorbent paper.

Typical experiment

Typical experiment

♦  Determination of substance concentration in solution (Bill's law).

Others

♦  Effect of concentration on the rate of chemical reaction -- Potassium Permanganate solution and oxalic acid solution by reaction.

♦  The effect of concentration on the reaction rate -- sodium thiosulfate reaction with concentrated sulfuric acid.

♦  Determination of vitamin C content in Juice.
