Subject: [rollei_list] RPA, Efke 25, fixer with hardener?
A friend of mine is sending me a box of Efke 25 film sheets 6.5cm x 9, this is the exact size for the Rollei plates adapter.I have read the emulsion is soft too much while wet and then Efke suggests a fixer with hardener. I have available to buy a Kodak rapid fixer with hardener, is it necessary really? or could I handle the wet film sheet with care avoiding to buy a new fixer?. BTW I have never used the Rollei plates adapter yet, I have never developed film sheets yet (I have a Domi-Plan tank)and I have never used hardener, modern emulsions don't need hardener, older ones -Efke 25 uses an Addox formula- needed one often. 
TIA

Keep in mind that the hardener works only during the latter part of the fixing and during washing. Unless you are going to wash in warm water the hardener should not be necessary. By warm I mean in excess of about 75F. According to one chemist the hardener has no effect on the dry emulsion.
