Multi-injection valve, biocompatible

Multi-injection valve, 1/16", V 4.1

The multifunctional injection valve allows several ways to inject a sample without the need to change the system configuration. The sample loop is either filled manually by syringe or automatically via a sample pump. By switching the valve the sample is then injected by the system pump. As an additional option, the sample can also be injected via the sample pump directly to the column.



Manual Load & column equilibration
The sample loop is manually filled via a syringe and the column is equilibrated via the system pump.







Sample Injection
The flow of the system pump is directed through the loop and sample is injected onto the column. Additionally, the flow of the sample pump is directed to Waste 2.











Direct Injection
The sample is loaded directly onto the column via the sample pump. Additionally, the flow of the system pump is directed to Waste 1.








Automatic Load & column equilibration
The sample loop is automatically filled via the sample pump and the column is equilibrated via the system pump.
