Sensors New Solutions for DO and pH Measurements
Hamilton has expanded its product range for Single-Use applications to cater for the growing demand of sophisticated sensors in single-use bag and bench-top applications.
The completed line of pH sensors for single use applications have a length of up to 425 mm. Such long length is nowadays needed for single use applications in rigid wall bioreactors, opines the firm. The sensors of the ‘One Ferm’ product line are available with various electrical connector configurations. An individual bag port allows for easy bag integration.
The new Visiferm DO SU is a sensor for precise measurement of dissolved oxygen in the medium. According to the company, it is available with the newly designed ODO Cap S0, which is particularly suited for bag applications. The sensor features a very robust design, which is especially for stirred tanks a practice-oriented solution and close to zero drift offering comparable measurement performance as known already from Hamilton’s traditional sensors.
Key goal during the development of this new breed of single-use sensor solutions was the simplification of sensor management during start-up and operation. Both pH and DO sensors retain the high accuracy performance even after gamma irradiation and allow a sufficient shelf life of up to 18 months.
