Record the number of plates processed
To determine when a tubing cassette has reached the end of its expected lifetime, make
a habit of counting and recording the approximate number of plates and volume
dispensed per cassette.
Create a form similar to the example table below or estimate your usage of the cassette
and project a date for replacement or recalibration.
Cassette Types Cassette Life Total Volume
1 µL 1000 384-well plates @ 5µL/well 2,000 mL
1 µL 1536 250 1536-well plates @ 5µL/well 2,000 mL
5 µL 1000 96-well plates @ 50µL/well 5,000 mL
10 µL 1000 96-well plates @ 100µL/well
10,000 mL

You may want to create a form similar to this table to keep track of the volume
dispensed with each cassette:
Cassette serial #: 2178
