One cartridge contains enough reagents to run approximately 120 measurements. The % remaining is indicated in the side bar menu on the instrument screen. Changing the cartridge takes a few minutes and does not require any special tools.
The reagent cartridge is located in a compartment at the top rear of the instrument as shown below.
When the reagent level stated in the side bar menu is 5% or lower, or if an experiment result gives an error code stating reagent cartridge is low, the reagent cartridge should be replaced as per the instructions below. This should not be done while an experiment is running.
1. Open the reagent cartridge cover by pressing down on the circular marking on the cover.
2. Remove the 4 fluid connections (red, blue, green and grey) by pressing the button on each connector and lifting the hoses off.
3. Remove the pneumatic connection by holding the base of the connector firmly and lifting it off.
4. Carefully lift out and remove the old cartridge from the instrument.
5. Unpackage the new cartridge and remove the coloured blanking covers on the ports. Place the new cartridge into the instrument ensuring it is the right way around – as pictured above.
6. Firmly reconnect the 4 fluid connections, following the colour coding on the connectors and the cartridge.
7. Reconnect the pneumatic line by holding the top of the connector and pressing onto the central port, until a click is heard and the orange sleeve on the connector is revealed. Once all connections are made, close the reagent cartridge cover again until it clicks shut.
8. On the instrument touchscreen, open the side bar menu – you will see the low cartridge % is still displayed.
9. Select Settings, then Machine, and touch on the blue button labelled “manually change the cartridge ID”
10. Type in the desired cartridge identifier – today’s date is recommended to record the date of the change, but this can be any value you choose. Press “update cartridge ID” to save.
11. The low cartridge % will still be displayed until an experiment is run or the instrument is restarted.
Reagent cartridges are disposable and should not be re-filled.
