I have used an Omnilog before, and it was useful to follow bacterial growth versus time. However, I'd rather use a 600nm turbidity read to avoid redox dyes, and I don't need 48 plates at a time, but would like more than 1.
Any suggestions on equipment available? In summary, I am looking for something smaller and cheaper than, for example, the Omnilog instrument. Thanks in advance!
I can second the Bioscreen C - a veritable workhorse in our laboratory. The BioScreen can read 200 wells at a time, with incubation, shaking and multi-wavelength absorbance. The price for a new one is around 25000$. Thermo-Fisher sold of the technology to Growth Systems Oy, and they are currently developing an updated version, due to be completed later this year.
Another option which we recently invested in is the oCelloScope - a really neat automated microplate time-lapse microscope which can also read out OD. As a bonus you get quantified per-cell morphology changes, etc. Highly recommended!
Check out the youtube link for the oCelloScope, especially around 2:20 for bacterial growth curves.
Good luck!

Philips has decided not to continue the oCelloScope system as it was not in line with their business strategy. I would like to know if you are aware of any other closed oscilloscope system? Thanks, Dory
This is true, and very unfortunate. The system is very powerful. I have heard that Philips are negotiating for another party to acquire the oCelloScope system and continue development - more details will come in the following months.
I could recommend the MilliDrop Analyzer (www.millidrop.com). It will be lunched in september. I would love hear your feedback and know wether this is something you could use.
An affordable and very good option is either TECAN Sunrise if you'll be measuring Abs only or TECAN Infinite if you need to measure fluorescence and luminiscence. For me it really worked and improved my work a lot. you can look at our lastest pulbications on vibrio. Cheers!
Can anyone give some idea of the pricing of the oCelloScope system ?
We are happy to announce that BioSense Solutions has taken over the oCelloScope business from Philips BioCell effective from May 1st 2017.
BioSense Solutions will take over sales, service, production and development of the oCelloScope platform.

Bioscreen C's were the workhorses of my graduate school lab and I had a very positive experience using them for growth curves. My current lab has an oCelloScope, and I don't like it nearly as much. In theory it's a great technology, but we are never able to get good quality images from the oCelloScope, and I prefer the simplicity of the Bioscreen to be honest. I also wasn't aware that another company had taken over from Philips, so I thought my current group was SOL.
