6.0 Care and Maintenance
As RoboSep™-S uses disposable pipette tips in a column-free system, no daily maintenance is required.
However, the following routine maintenance and cleaning steps are recommended to ensure optimal
performance, reliability, and longevity of your instrument:
Lightly spray the instrument’s external surfaces with 70% ethanol or 70% isopropanol and wipe clean
with a soft, clean towel (section 6.2.1).
Verify that the hydraulic fluid bottle is full of sterile deionized water (section 3.5).
Clean the tip head (section 6.1).
6.1 Cleaning the Tip Head
Use the RoboSep™ Tip Head Polishing Compound (Catalog #20119) provided with the instrument to clean
the tip head. Do not apply other cleaning agents to the tip head.
Note: The RoboSep™ Tip Head Polishing Compound can be conveniently stored in its designated
compartment in the instrument (Figure 1).
Over time, the tip head can accumulate a thin film of plastic from repeated loading and unloading of pipette
tips. This accumulation can prevent RoboSep™-S from stripping the disposable pipette tips from the tip head.
RoboSep™ Tip Head Polishing Compound is specially formulated to help remove this build up and disinfect
the tip head when used as described below:
1. Apply 1 - 2 drops of RoboSep™ Tip Head Polishing Compound to a clean paper towel or other
non-abrasive laboratory wipe.
2. Wipe the RoboSep™-S tip head.
3. Use a clean paper towel or other non-abrasive laboratory wipe to polish the tip head. Ensure that all
traces of the cleaner are removed.
6.2 Cleaning RoboSep™-S
6.2.1 External Surface
It is recommended to clean RoboSep™-S by lightly spraying the instrument’s external surfaces with
70% ethanol or 70% isopropanol and wiping clean with a soft, clean towel. RoboSep™-S can also be wiped
down with a dilute bleach solution (e.g. 1 in 10 dilution of 5% sodium hypochlorite solution), but should then
be wiped clean with water afterwards.
To avoid fluid seeping behind the touchscreen’s external surface it is recommended that the 70% isopropanol
or 70% ethanol be sprayed on a soft, clean towel prior to wiping down the touchscreen. Do not allow excess
fluid to pool at the margins of the touchscreen.
