1. Inlet part; 1a. Luer cone for connecting to washing head; 1b. Flowrate regulator; 1c. Lid GL45 with plug;
1d. Luer cone for connecting syringe; 2. Connection of washing heads; 3. Outlet into waste system;
4. Syringe 50ml
4.5.1. Simple Manual Use
Connect both
Washing heads
in series using tubing and LUER adapters. Fill syringe with
HPLC water (or mobile phase dissolving buffers) and wash the heads (flowrate regulator must be
opened). Washing heads are now filled with liquid, rinsing the pistons from rear side. Now, once in
a while during work with the pump, push some liquid through the pump washing system (approx.
1x per hour 5 ml).
4.5.2. Automatic Backwash
Connect both
Washing heads
in series using tubing and LUER adapters. Insert tubing with
flow regulator into reservoir with HPLC water (or mobile phase dissolving buffers). Loosen the flow
regulator and suck liquid into the system using plastic syringe (picture on left). Close the flow
regulator, disconnect syringe and place the tubing end into waste reservoir. Loosen the flow
regulator and now the liquid is flowing through the system by gravity (picture on right). Set the flow
regulator so that at the end of the tubing escapes approx. 5-7 drops per minute.
