Page 22: Low Flow Sampling
Low Flow Sampling The standard compensated flow range of the Universal MTX series pumps is 1000 to 4000 ml/min. To operate at flows in the range 5 to 500 ml/min an optional low flow adapter / tube holder is required. Low flow adapters are available for simultaneous sampling using one, two, three or four sample tubes (refer to the sampling accessories guide on pages 26 and 27 for details). - Page 23 Low Flow Sampling Stand the pump upright on a level surface and set the pump running. Set the pump flow rate to approximately 1.5 l/min. The built in flow indicator rotameter can be used to make this setting as only an approximate flow rate is required.
