\"chill\"<\/a><\/p>\n

Many lasers have baseplates with channels through which chilled water is pumped to dissipate heat and stabilize the temperature of the system. I haven’t had much trouble with the chillers and baseplates of Newport\/Spectra-Physics systems. However, most of the Coherent Chameleon systems I’ve worked with (3 out of 4) have had problems with the water chiller and\/or baseplate. The chillers broke down and had to be replaced (repeatedly) and\/or the baseplates got clogged (which can lead to the tubing popping off, pictured above). What has been your experience?<\/p>\n

On the confocal listserv, Craig Brideau recommended<\/a> household vinegar or a 5% acetic acid solution to clean out a clogged baseplate. <\/p>\n

Philip Oshel offered his recipe<\/a> as well: <\/p>\n

I’ve used both hydrogen peroxide and CLR (brand name lime & rust remover). For a TEM-sized chiller, this took one bottle of CLR or 1 Liter of 3% H2O2 (or 100 mL 30% H2O2). Circulate this for one to six hours, or even overnight if needed (sounds like that will be needed in your case), followed by flushing with 4-5 volumes of tap water. This works well, and causes no damage to instrument chilling lines. When I had a biofilm-sludge clogging problem, the vinegar trick worked. I used about 1 Liter of vinegar for this, followed by tap water.<\/p><\/blockquote>\n

We use Optishield in our chiller water supply to keep it clean. And we flush it regularly. Even that isn’t always enough to avoid problems.<\/p>\n","protected":false},"excerpt":{"rendered":"
