Washing E.coli cells/ osmotic pressure determination

We are currently washing E. coli cells with a water solution containing 9 g/
l of NaCl. However, it seems that we have some cell lysis.
I was wondering if it was an osmotic pressure problem? Do you know a simple
methode to measure an osmotic pressure? Do you know if I must modify the
concentration of NaCl that i'm using.

Thank you for your help.
