In order to protect our employees as well as our equipment, we need information from you on the application for which the returned goods were used. The enclosed declaration is compulsory and binding and may only be completed and signed by authorised personnel.

Returned goods must be accompanied by a completed and signed declaration in order for Festo to perform an inspection and fault analysis. We reserve the right to reject shipments that do not meet this requirement.

This application note covers the following topics:
• The challenges of dispensing on the fly.
• Parameters to consider for dispensing on the fly.
• How to define the system and calculate the right parameter values to obtain       accurate dispensing results.

A checklist to avoid EMC trouble

Flushability of media separated valves describes the performance of flushing liquid out of a valve with another liquid with as less volume as possible. A good valve design with little dead volume and therefore a good flushability is important when using media separated valves in laboratory applications e.g. for cleaning processes or with expensive liquids. A flushability test with two different liquids refers as an indicator of good valve design.

This application note covers the following topics:

• Description of a test setup to make the small internal volume and the flow-optimized design visible.
• Comparison of the flushability performance of different media separated valves.

Festo SE & Co KG complies with national and international laws, guidelines, standards and regulations which are applicable to our products. We constantly monitor the dynamics of legislation. This Application Note give an overview.

This Application Note describe the most common terms about the evaluation of results of a dispensing or pipetting application. In particular: accuracy, trueness, precision, repeatability, reproducibility, coefficient of Variances (CV), mean and standard deviation as well as maximum permissible error.

The application note describes the influence of heat input in media-separated valves on the flowing fluid. It compares the heat input from different manufacturers, flow rates and provides suggestions for reduction.

Description of application test results and technical features of the VYKA valve that are not included in the regular datasheet values.
