Bio-rad laboratories india offers duoflow ph monitors. The biologic duoflow in-line ph monitor enables real-time monitoring of ph conditions during a sample run. Key features of the ph monitor include a calomel electrode that unlike ag/ agci electrodes, ensures compatibility with buffers containing tris; a single body containing the ph and reference electrodes, to minimize reference dry-out and eliminate the need to add electrolyte solutions; flow rate capacity of 80 ml/min [75 psi backpressure] to accommodate larger columns; and biocompatible peek flow cell with a swept volume of 80 ul for high precision and accuracy. The ph monitor is supplied with 1/4-28 fitted peek tubing for a fast and easy addition to any biologic duoflow or biologic hr system. The electrode connects directly to the biologic maximiser valve system`s bnc port or for systems without a maximiser via a signal import module. In addition to being available separately, the ph monitor is included with all biologic maximiser kits, biologic duoflow maximiser systems and biologic duoflow pathfinder systems.
