WARNING
Corrosive substance. NaOH is corrosive and therefore dangerous
to health. When using hazardous chemicals, avoid spillage and
wear protective glasses and other suitable Personal Protective
Equipment (PPE).
NOTICE
The flow cells must not be used at pressures above specified
pressure. At higher pressures the flow cell may break.
Pump a cleaning or sanitizing agent through the flow cell. The standard recommendation
is to pump 1 M NaOH at 1 mL/min for 30 minutes and then wash out with buffer.
