Description:

2. Open both cocks (5005) and allow the gas to sweep through the absorption burette and caustic reservoir to completely displace air in the glassware. If preferred, the bulb may be first filled with water and the water displaced with the gas to be tested.

3. After the sample has been taken, close the cock on the absorption burette first and then close the cock on the caustic reservoir.

4. Pour the caustic solution into the reservoir to the line indicated on the bulb (approximately 105 cc).

5. Open the cock on the caustic reservoir and allow the solution to flow down into the absorption burette. Absorption of the CO2 gas now takes place until only air in the sample remains, the small bubble of which may be moved around by tilting the Purity Tester slightly, thereby insuring complete absorption of the gas.

6. Close the cock on the caustic reservoir and turn the instrument 90 degrees so that it rests on its other frame side. In this position, the unabsorbed gas enters the calibrated neck where the volume is directly indicated. The percentage purity of CO2 gas is 99%. plus 1/10 of 1% for each division as indicated by the level above the bottom graduation (Using the standard absorption burette #10101). There are our other types of absorption burettes available which are listed below.

7. After the test is completed, empty the caustic solution from the Purity Tester. Place the Purity Tester over a container and open both cocks to allow the caustic to drain out. Rinse out all traces of caustic with warm water and dry the glassware before returning the tester to its case.
