I have never run a BOD test using 60ml sized bottles. Using wastewater and DOmeter readings are the results comparable and acceptable to 300ml bottle results?

The most important thing to keep in mind when using a different size bottle is to keep the volume percentage of sample the same. If you are used to using 100 mL of sample in a 300 mL bottle you would need to reduce that down to 20 mL of sample in a 60 mL bottle. Similarly, when preparing the GGA standard you will need to make sure that you use 20% of what is normally used.

Do you have a question?
