The Melton and Eggan labs from the Stem Cell and Regenerative Biology Department recently switched from using disposable plastic bottles to reusable glass bottles for filtering media for tissue culture. The conversion saved them over $9500 in the first 7 months, and has prevented 2600 plastic bottles from going into the waste stream so far. The labs are almost through their first year using the glass bottles, and have not experienced any problems or issues. This is an excellent best practice for any lab that does a significant amount of tissue culture! Email energy@fas.harvard.edu for more information and how to get started.
