Level Sensing Probes Ensure Smooth Processing

Aug 16 2007

For automatic control in analytical instruments, DIBA Industries' Conductive Level Sensing Probes monitor liquid quantity, notifying system software when processing fluid bottles have reached full or empty states. In addition to allowing instrument software to detect and react to system status, Diba's fluoropolymer lined aspirate and dispense probes provide an inert, consistent fluid path with no possibility of leaks from tip to pump.

Diba's Level Sensing Probes accurately monitor sample levels in cuvettes, as well as waste, reagent, and buffer solutions, providing analytical instrument software the information needed to direct system changes. Depending on the application, information from the probes can be used by the system to automatically stop processing until reagent or buffer solution is replenished or a waste bottle is emptied.

The compact probes require only a simple electrical connection and have no moving parts to fail, resulting in more reliable operation when compared to the bulky float switches traditionally used for level sensing.

The inner diameter of Diba's stainless steel probe can be lined with PTFE or FEP fluoropolymer tubing to create a single inert fluid path, eliminating the possibility of unwanted chemical interaction and the potential introduction of air along the entire length of the tube. The design reduces carryover and improves wash capabilities, retaining the necessary flow characteristics for efficient system performance.
