How to calibrate a pH sensor in DASware control?

DASware control software allows for parallel calibration of all sensors used within one system with all data logged in the central database together with set-points, profiles, cascades, process values, user interactions and other events. Good maintenance will prolong the sensors' lifetime whereas high temperatures (i.e. during autoclavation), alkaline solutions (i.e. during alkaline deactivation), repeated etchings and improper maintenance will reduce the electrode's lifetime.

Is it possible to automatically control the foam in DASGIP vessels?

All DASGIP vessels can be equipped with foam control components. All you need is a level/foam sensor connected to the DASGIP sensor module (e.g. PH4PO4L) and a feed line for dosing of the antifoam agent. Now foam formation can be detected by the level sensor and antifoam agent is automatically pumped into the vessel until all foam is collapsed. The DASware control software allows any feed line to be used for antifoam or level control. Since medium composition has a strong impact on the electrical conductivity of medium and foam, every conductivity-based level sensor needs to be adjusted to foam and medium conductivity. DASware control supports monitoring conductivity and free adjustment of the conductivity threshold.

What do I have to consider when returning equipment for repair?

Equipment returned to Eppendorf for service or any other reason needs to be decontaminated first. Please fill out the Decontamination Form that you will find in the “Service & Support” section of the Eppendorf website and attach it to the package. Equipment which was sent without the completely filled form cannot be handled. This form must also be completed before any on-site service, whether covered under warranty or not, can commence.

What does your warranty cover?

Eppendorf issues a warranty of one year from the day of delivery on its products in accordance with our terms and conditions. Excluded are consumables such as cables, tubing, glassware, and sensors as well as used material.

DASGIP^® PHPO for Monitoring of pH, DO, Redox and/or Level

Product Information

pH and dissolved oxygen are two key parameters monitored and controlled in most bioprocesses in order to achieve optimum growth conditions. Depending on the application, measurement of redox potential and/or level is desired. The Eppendorf DASGIP PHPO module series provides flexible solutions for all these requirements.

Features

Eppendorf provides a range of DASGIP bioprocess monitoring modules delivering precise measurement and real-time control of pH, dissolved oxygen (DO), redox potential (ORP) and/or level/foam. Industry standard sensors can be connected. The monitoring systems enable parallel monitoring of four or eight pH sensors with temperature compensation. Additionally, up to two Pt100 temperature sensors can be connected and two 0/4-20mA/0-10V analog inputs provide external signal integration. An easy-to-use one- or two-point calibration procedure for pH, DO and temperature is integrated for use with DASware^® control.
The four-channel modules PHPO (configured for pH and DO control) and PHPORD (pH, DO and ORP) each feature four optional conductivity-based level inputs. These inputs can be used for level control during continuous operation or automated antifoam addition.
