Appendix A. Maintenance
The Trans-Blot® Turbo™ system requires little maintenance. After you finish using the Trans-Blot Turbo
system, rinse each cassette, base, and lid in deionized water to remove residual salts and to prevent salt
buildup. Air-dry or use a paper towel to dry the cassette.
For each transfer cassette there are four connection contacts located at the back of the instrument base
cavity (Figure 20). Over time it is possible that buffer or other contaminants have been exposed to these
contacts causing them to stick in the depressed position. With the unit unplugged, take a moment to
use isopropyl alcohol and a cotton swab or isopropyl wipes to clean these contacts. Push on each
contact to ensure that they all depress freely. The contacts should be checked and cleaned monthly as
part of standard equipment maintenance procedures
Clean any accidental buffer spills in the instrument bays with a dry towel.
The cassettes and instrument casing can be cleaned with water and mild detergent; do not use
abrasives or organic solvents.
Periodically unplug the instrument and wipe the instrument casing with a moist cloth or paper towel.
Ensure that the electrode contacts in the bays are clean. Electrode plates should be occasionally
cleaned with deionized water or a mild detergent to reduce salt buildup. If the cathode plate has
excessive salt buildup, 7% acetic acid can be used to remove the residue.
Occasionally check that the cooling fan vent is free of debris and dust.
