SECTION 4 – PErFOrMING MICrO VOLuME MEASurEMENTS
For detailed descriptions of the measurement modes that are available on the Genova Nano
spectrophotometer please refer to the supplied Genova Plus operating manual.
4.1 PIPETTING SAMPLES ONTO THE MICrO VOLuME rEAd HEAd
The Genova Nano spectrophotometer is designed to measure sample volumes ranging from 0.5μl to
5.0μl.
Jenway recommends that users should, if possible, use at least 2μl of sample for their
measurements.
Pipetting a sample onto the read head
Read head in rest position
1. With the read head mechanism open, pipette the
liquid to be analysed onto the centre of the lower
read head.
2. Close the lid of the spectrophotometer. This will
lower the read head assembly down onto the path
length drive motor. The upper read head will now
be in the rest position, 2mm above the lower read
head.
3. When a measurement is initiated, the path length
drive motor lowers the upper read head to the
specified measurement distance, the photometric
measurement is taken and the upper read head is
then returned to the rest position.
