Colorimetric Tubes
The Colorimetric tube is the main instrument for visual colorimetric analysis experiments in chemical experiments. It can roughly measure solution concentration. During the color comparison, place the color comparison tube of the solution to be tested and a color comparison tube of the standard solution in front of a white paper with the same light intensity for comparison, and observe the color difference with the naked eye.
There are two kinds of colorimetric tubes: full-scale and double-scale. And the standard sizes are 10ml,25ml, and 100ml.
Color: Transparent/Amber.
With a Frosting stopper design: It can effectively prevent liquid leakage.
Material: High borosilicate glass, excellent transparency.
Accept customized sizes.
General Size Details of the colorimetric tubes
| Size (ml) | Height (mm) | Bottom Diameter (mm) | Neck Diameter (mm) |
|---|---|---|---|
| 10 ml | 141 mm | 10 mm | 12 mm |
| 25 ml | 170 mm | 20 mm | 16 mm |
| 50 ml | 202 mm | 25 mm | 19 mm |
| 100 ml | 240 mm | 30 mm | 24 mm |
P.S:
1. The colorimetric tube is not a test tube, and the tube wall is thin. Try to avoid heating it or only slightly heating it.
2. Please use a color comparison tube of the exact specification for color comparison.
3. It is not allowed to brush with a stiff brush to avoid affecting the light transmittance.
