SECTION 6 – CLEANING ANd dECONTAMINATION OF THE
MICrO VOLuME ACCESSOry
6.1 ACCESSOry CLEANING
Wiping the sample from both the upper and lower read heads upon completion of each sample
measurement with a lint free cloth is usually sufficient to prevent sample carryover and avoid residue
buildup. Although generally not necessary, water aliquots can be used to clean the measurement
surfaces after the measurement of particularly high concentration samples to ensure no residual sample
is retained on either read head. After measuring a large number of samples, however, it is recommended
that the areas around the upper and lower pedestals be cleaned thoroughly. This will prevent the wiping
after each measurement from carrying previous samples onto the measurement pedestals and affecting
low-level measurements. A final cleaning of all surfaces with deionised water is also recommended after
the user’s last measurement.
6.2 ACCESSOry dECONTAMINATION
If decontamination is necessary, a sanitising solution, such as a 0.5% solution of sodium hypochlorite
(1:10 dilution of common commercial bleach solutions – freshly prepared), can be used to ensure that
no biologically active material is present on the measurement read heads. The read head fittings are
made from stainless steel and are resistant to most common laboratory solvents. See Section 11 -Solvent
Compatibility for full details.
6.3 rEAd HEAd rECONdITIONING
The Bradford reagent as well as other buffers containing surfactants can “un-condition” the measurement
read head surfaces so that the liquid does not form a stable sample droplet. If this occurs, “buff” the
read head surfaces by rubbing each measurement surface aggressively with a dry laboratory wipe 30-40
times. This will “re-condition” the surface allowing the sample droplet to form.
