McClean: Cleaning Floating Pin Replicators
This is the procedure for cleaning the 96-format and 386-format floating pin replicators. You must perform this procedure between every pinning step when pinning strains from liquid culture to agar, from frozen stocks, etc.
- Square liquid reserviors (kept in drawer with pinners or on pegs over the sink)
- Reservoir 1: 100ml deionized water
- Reservoir 2: 40mls of 10% bleach
- Reservoir 3: 50mls of deionized water
- Reservoir 4: 70mls of deionized water
- Reservoir 5: 100mls of deionized water
- Reservoir 6: 95% ethanol
- Floating pinner
- Flame source
- Fill the reservoirs as described in the 'Materials' section above.
- Set the replicator into Reservoir 1 (water) and agitate by hand for 1 minute
- Set the replicator into Reservoir 2 (bleach) and agitate for 30 seconds
- Set the replicator into Reservoir 3 (water) and rinse briefly (~ 5 seconds)
- Set the replicator into Reservoir 4 (water) and rinse briefly (~ 5 seconds)
- Set the replicator into Reservoir 5 (water) and rinse briefly (~ 5 seconds)
- Set the replicator into Reservoir 6 (ethanol) and rinse briefly (~ 5 seconds).
- Remove the replicator from Reservoir 6 and allow the excess ethanol to drip off of the pins
- Flame the pins. Allow the pins to cool to room temperature before using the replicator.

'''*~~~~''': Be careful with ethanol and flame! If you accidentally set the ethanol bath on fire (which should not happen if you allow the pins to cool and follow all of the wash instructions) don't panic! Cover the container to exstinguish the flames.
