SAMPLE RECOVERY OR REMOVAL
Once a measurement is complete, the sample solution can be recovered from the lower read
head with a suitable pipette or removed from the read heads by cleaning with a suitable lint
free cloth.
1. Open the lid of the spectrophotometer.
The read head mechanism will open to
allow access to the upper and lower read
heads
2. The sample can be recovered by carefully
drawing the liquid that is retained on the
lower read head into a clean pipette tip.
3. Both read heads should then be wiped
with a lint free cloth.
4. More rigorous cleaning may be required after the measurement of high concentration
samples or samples that pose a contamination risk. See section 8
for further details.
