Dears,
for testing plastic containers for leakage according to Eu. Ph. Ed 11th the method demands the use of absorbent paper (impregnated with chemical indicator, such as blue bromophenol or an equivalent dye).
Is there anyone that can recommend to me a company where I can purchase paper sheets with such features? I mean large paper sheets, A4 format as instance.
As an alternative, can someone recommend me or share with me a procedure or work instruction where I can find the "recipe" to hand made manufacture lab indicator paper sheets?
I thank you in advance for your attention and your helpful advices.
