This 30mL Stop Bath Indicator Kit from Flic Film indicates when the bath is exhausted and no longer effective. The use of a stop bath neutralizes the developer which sets the development time, prolonging the life of the fixer.

This kit contains a spoon for testing your stop bath. Only two drops are needed in the spoon. If the stop bath turns yellow, it's still good to use. If it turns clear of purple, the stop bath is expired.

Q: 4. What is the highest temperature the device can achieve and maintain?

A: The manufacture does not list the temperature the heater works with but it is for processing so the Flic Film Precision Temperature Water Bath should be fine for regulating at 68 F. But note it does not have a cooler only a heater. So if the room you are in is over 68 degrees that could be an issue.

Q: 5. Can this be used for prints as well?

A: The SIMPLICITY Stop Bath from Ilford is a pre-measured portion of ILFOSTOP liquid concentrate stop bath, delivered in a single-use sachet, which is enough to process exactly one roll of 120 or two rolls of 35mm film in a two-reel, 600mL developing tank. While the stop bath may work for RC paper, I would not recommend it as there is not enough for multiple printing needs.
