NOTENOTE
Since the resin levels may have been adjusted in the preceding procedure (Checking the resin
and liquid levels, page 39), it is assumed that the resin in the microtiter plate wells comes up no
higher than 4.5-5.0 mm (6 mg resin plates) from the bottom of wells.
NOTENOTE
The instrument assumes measurements are from the top of the well down. However, it is physically
easier to measure from the bottom of wells. You will convert your measurement to the instrument’s
top-down scheme in the next step.
4. Add 0.5 mm to the resin height obtained in step 3 and subtract that sum from the well
depth. This is the aspirate offset.
NOTENOTE
Figure 2.31 and Figure 2.32 show example aspirate offset calculations for a specific type of plate.
For a different brand of plate, substitute its well height (usually available in technical specifications
on the manufacturer’s website).

Figure 2.31 Aspirate Offset Example Calculation
This example calculates the aspirate offset for a 384-well microtiter plate (Thermo
Scientific AB-1384).
Figure 2.32 Aspirate Offset Example Calculation
This example calculates the aspirate offset for a 96-well microtiter plate (Thermo
Scientific AB-0800).

9.25 mm
4.25 mm resin height
Aspirate offset = 9.25 mm
- (resin height + 0.5 mm) = 4.5 mm
15.00 mm
4.0 mm resin height
Aspirate offset = 15.00 mm
- (resin height + 0.5 mm) = 10.5 mm
