Synonym: FLOWMETER 10CC EA
Product Type: Chemical
| flow meter volume | 10 mL |
| packaging | pkg of 1 ea |
| technique(s) | gas chromatography (GC): suitable |
| Application: | Bubble flowmeter may be used to manually control the flow at the system outlet during analysis of perfluorobutane (PFB) in the exhaled rat air using respiration-metabolism chamber system and a GC-MS method. Bubble flowmeters can be used to check splitter or detector flow or to calibrate personal pumps for accurate air sampling. |
| General description: | Bubble flowmeter is a simple and precise way to measure flow rates of gases. It is the most common device for measuring a volumetric flow rate. This unit has a buret of appropriate volume fitted with rubber bulb at the bottom and a side arm. Air is passed into the buret and the bulb filled with soap solution is squeezed. This causes a soap bubble to enter the buret. The time taken for the bubble to travel in considered as known volume, used to calculate the flow rate. |
| General description: | The most basic configuration of a bubble flowmeter is a calibrated tube, a stopwatch, and a good eye. The bubble is timed as it moves up the calibrated tube between two markings. Flow tubes are graduated as follows: • 10 mL tube in 1 mL increments • 25 mL tube in 5 mL increments • 50 mL tube in 10 mL increments • 100 mL tube in 20 mL increments Includes glass flow tube with two magnetic clamps, a short piece of Tygon tubing and a squeeze bulb. Stand not included. |
