In 1986 Broadley-James introduced the first steam-sterilizable, gel-filled and sealed pH sensor. The pH FermProbe® met wide acceptance in the biotechnology and pharmaceutical industries for use in fermentation processes. In 1993 Broadley-James introduced the OxyProbe® dissolved oxygen sensor, providing a complete solution for measurement and control in both cell culture and fermentation processes. In 2003 Broadley-James introduced the BioNet® bioreactor control system based on the Delta-V Distributed Control System. Providing Industrial Tools for Industrial Science, Broadley-James continues to advance the state of the art in measurement, automation and control. We also distribute a range of innovative products from our partners, for both Upstream and Downstream bioprocessing.

autoclavable bioreactor fermenter


The Broadley-James Bioreactor is the latest in autoclavable benchtop glass vessels. Available in a range of sizes: 3, 5, 7, 15 and 20 litres total volume. All metal components are manufactured from 316L stainless steel with electropolish. Integral scaling, improved component designs and extensive product inventory makes this the most user-friendly bioreactor available.

pH dissolved oxygen cable


Stock detachable cable assemblies feature the most commonly requested cable lengths and connector schemes for all Broadley-James pH & redox electrodes and OxyProbe® dissolved oxygen sensors. Cables are tagged with replacement part numbers to enhance field serviceability and are 100% tested for continuity, polarity, and the absence of short circuits. Moulded strain relief and stainless steel threaded retainers ensure long cable life.

pH dissolved oxygen accessories


The primary components of a measurement loop are the sensors and transmitters. However, when readings are suspect or if noise and interference are a problem, it can be hard to find the source of the problem without having the proper equipment. Many of the BioProcess accessories are designed with troubleshooting in mind, allowing the metrology department or even the operator to diagnose equipment quickly and efficiently.

pH dissolved oxygen housings


The electrode housing is designed to hold and protect the pH electrode while inserting it into the bioprocess vessel. There are various types of side-entry ports and different groups of housings to fit each port type. The size and make of the port must first be identified in order to narrow the selection process.
