DO NOT add water, especially if the acid is highly concentrated, as it may splatter and contaminate you work station. If the acid is not very concentrated, you can just flush everything with plenty of water and remove all bottles, beakers, etc. from your work station ASAP! Wear gloves, goggles and a lab coat at all times, of course!
Generally speaking, glass bottles will work for the SODIS process although they are much thicker walls and generally do not allow as much UV radiation through as thin walled clear plastic PET bottles which are the container of choice. The main disadvantages of glass bottles are the weight and the fact that they can break if dropped. They are also not as plentiful in the rural areas of developing countries where this process is being targeted at the household level. Another disadvantage is the lack of screw top lids found on plastic bottles. They are more difficult to cap and prevent leakage during the process.
