Frequently Asked Questions
All Galaxy® CO2 Incubators
Q: I am hesitant to move from a water-jacketed incubator to a direct heat system. Why should I switch?
A: While water-jacketed (WJ) incubators have, in the past, been suitable for generalized cell culture, they truly are an outdated technology. WJ incubators are bulky, often taking up valuable lab space, offer less capacity in relation to that space, have lower performance and control, are difficult to maintain and do little to prevent contamination. High-temperature disinfection is also not possible in WJ designs. The direct-heat design provides an innovative solution to these issues and is ideal for culture in today’s laboratory.
 Q: I am interested in the high-temperature disinfection (HTD) option for periodic preventative maintenance. What can you tell me about its effectiveness?
A: The Galaxy has a 120°C 4-hour HTD cycle that has been shown to be very effective in controlling contaminants. See www.nbsc.com/galaxy for downloadable report. Sterility is a function of temperature and time in these cases. The CO2 sensor does not have to be removed from the unit, making running the HTD cycle efficient, rapid, and effective.
Q: I may want to add the O2 control option to my Galaxy incubator at a later date. Can this be retrofitted?
A: The O2 control feature cannot be field retrofitted and is only factory installed. We suggest ordering it at the time of purchase to provide a single incubator that will meet your requirements for many years to come.
Q: Can I externally data log my incubators?
A: Yes, all new Galaxy incubators come with an integrated RS-232 port that allows data to be logged remotely using BioCommand® SFI software.
Q: How should I clean/disinfect my Galaxy incubator?
A: Currently, the only acceptable disinfecting agent is a solution of 70% Isopropanol (isopropyl alcohol) and 30% distilled water. Carefully follow the cleaning guidelines described in your user’s manual.
Q: Are there any parts which should be regularly renewed on my Galaxy?
A: Yes. Replace the CO2 supply line HEPA filter and auto-zero HEPA filter* at least once per year. (* Auto-zero filter used in R models only.)
Q: Do you offer an incubator that can be run at around or below the ambient temperature of my lab?
A: Yes, we can offer the Galaxy 170 R with cooling option. The cooled incubator can be used normally at 37°C or other temperature above ambient, and also works at temperatures as low as 10°C below ambient.
