Overview
Glass Roche foam instrument 2151 Roche foam instrument (ROSS Files method) is an instrument for measuring the foam activity value of soap, synthetic detergent, laundry soap powder, shampoo, shampoo, shampoo, detergent (meal detergent), hand sanitizer and other detergents by solution falling method.
Product Details
Glass Roche foam instrumentNotes:
(1) The device must be completely vertical, otherwise the liquid level cannot be read accurately due to unevenness.
(2) The test solution should be preheated to around 41.5 ℃ before being placed in the dropper tube, and the temperature for formal operation after injection should be 40 ℃± 0.5. Otherwise, the temperature will have a significant impact on the data.
(3) The foam activity of some solutions is very unstable. A few minutes later, the foam surface bursts, becoming a rugged surface. At this time, the height reading can only take the estimated average.
Glass Roche foam instrumentProduct Instructions:
(1) Turn on the thermostat, and when the thermostat reaches a certain temperature, stabilize the temperature of the jacket water bath at 40 ℃± 0.5 ℃.
(2) Rinse the inner wall of the graduated tube with distilled water, which must be *, and then rinse the tube wall with the test solution, which must also be washed *.
(3) Close the scale tube piston and inject 50ml of test solution into another dropper until the 50ml mark is reached. Preheat the test solution to 40 ℃.
(4) Fill the dropper tube with 200ml of test solution, which is preheated to 40 ℃.
(5) Place the dropper tube on the pre prepared tube holder perpendicular to the cross-section of the graduated tube, so that the solution flows to the center of the graduated tube. The outlet of the dropper tube should be placed on the 900mm graduated line.
(6) Open the piston of the dropper and let the solution flow down. When the solution in the drip pipe has run out, immediately start the stopwatch, measure the foam height, and then record the height after 5 minutes, 10 minutes, and 15 minutes. The foam value is expressed in foam height.
(7) Repeat the above experiment two to three times, and before each experiment, the wall must be cleaned to affect the data.
