Sulfate Tester

Sulfate Tester is designed for the determination of chromium content of sulfate solution, the method is simple, fast, small error can be the result of ten minutes, do not do the work curve (the result can be obtained directly reading), without the preparation of standard solution , one can analyze the two samples.

Solved by complexometric titration and the weight of the law complicated, long time, could easily lead to large errors and other deficiencies, is the analysis of plating solution, a good helper network. Instrument: 1, the electric centrifuge (power 220V, 50HZ) 2, two tubes rapid determination of sulfate, stopper, measuring range 0.2?

5g / L 3, pipette (self): 20 ml 1, 5 ml 2. Reagents: 1, 3:1 hydrochloric acid: 3 volume of analytical grade hydrochloric acid and 1 volume of distilled water mix. 2, 25% of the barium chloride solution: 25 g of analytical grade barium chloride dissolved in 75 ml distilled water.

Analysis: 5 ml 25% barium chloride solution, close the lid after shaking, the determination of the centrifuge tube into the open the power supply, the instrument time to 4 minutes the location of the governor up to 1000 rev / min. Stops, remove the determination of tube, note the readings, that is, the content of sulfuric acid.

If the reading is 2.2, and sulfuric acid content of 2.2g / L. Note: 1, detector to be placed flat. Electrical connection before you check the power switch is in the closed position. 2, to ensure rotation time of less than 5 minutes, then in 5-6 minutes.

3, centrifugal rotation, you must also put two tubes in the centrifuge, the determination of the tube into the same amount of the solution, otherwise it will unbalance, damage to the centrifuge. 4, measuring the absolute error is less than ± 0.05g / L.

5, detector and measuring tube should be supporting the use of centrifuges or centrifuge tube using other, the Company is not responsible for the accuracy of determination. 6, determination is complete, timely and clean Determination tube. Careful determination of tube placement and use.

A fast detector sulfate, characterized in that the centrifuge (1) connection sleeve (2) constitute
