Removing Clogs
If you frequently use the FLEXMAP 3D system to test concentrated serum or other
debris ridden samples, Luminex recommends that you use the software to perform a
clog removal routine weekly. Luminex recommends using sodium hydroxide (NaHO) to
perform an alcohol flush of the FLEXMAP 3D instrument to remove clogs.
To remove clogs:
1. Replace the alcohol in the alcohol well of the reservoir area with a 0.1N sodium hydroxide
solution.
2. Use the software to perform a clog removal routine.
WARNING: Sodium hydroxide is extremely caustic. If it comes into contact
with skin, it can burn and cause tissue damage without causing
pain. Always wear gloves and goggles when working with
sodium hydroxide.
Cleaning the Sample Probe
WARNING: Avoid contact with moving parts. If a plate is running, use the
software to execute Stop to prohibit exposure to moving parts.
Refer to the software manual for instructions. The Luminex
®
FLEXMAP 3D ® system must not be performing any operations
while you carry out this maintenance procedure.
To clean the sample probe:
1. Use the software to execute STOP if a plate is running. Refer to the software manual for
instructions. The FLEXMAP 3D system must not be performing any operations while you
carry out this maintenance procedure.
2. Remove the sample probe.
a. Open the right front door of the FLEXMAP 3D instrument.
b. Unscrew the Cheminert fitting on top of the probe completely.
c. Grasp the probe gently and push up.
d. Lift the probe out of the top of the probe holder.
3. Clean the sample probe using either a bath sonicator or a 10 mL syringe. If you are using
a bath sonicator, place the tip of the sample probe in the bath sonicator for 2 to 5
minutes. If you are using a syringe, force distilled water through the tip of the sample
probe to its large end. This dislodges any debris clogging the tip.
