Further physico-chemical tests can be performed via subcontracts in our partner laboratories, e.g. Vapor pressure
Explosion testing
Relative self-ignition temperature
Oxidative (pyrophoric) properties of solids
All tests, if desired for registration purposes, may be carried out under both GMP and GLP conditions.
