NOTE
The gaskets used in the standard and semi-micro/micro flow cell are different.
CAUTION
Sample degradation and contamination of the instrument
Metal parts in the flow path can interact with the bio-molecules in the sample leading to sample degradation and contamination.
- For bio applications, always use dedicated bio parts, which can be identified by the bio-inert symbol or other markers described in this manual.
- Do not mix bio, and non-bio modules or parts in a bio system.
-
Use a 4 mm hex key to unscrew the window assembly (1) and remove the gasket (6,7) from the cell body. Do not mix the gasket #6 and # 7.
-
Use a tooth pick to remove the quartz window from the window assembly.
NOTE
If the washers fall out of the window assembly, they must be inserted in the correct order with the PTFE ring to prevent any leaks from the flow cell window.
