You can use preconditioned silica gel to establish just about any
humidity you desire.  We often need to condition our samples to 75%
RH.  We use

    Art Preservation Services
    315 East 89th Street
    New York NY  10128
    212-722-6300

They can prepare the conditioned silica gel to most humidities. Good
luck,
