A tablet sampler assembly is provided for a tablet coating machine which comprises a rotatable drum for containing a bed of tablets being coated. The tablet sampler assembly comprises a housing configured for attachment to said tablet coating machine, and a receptacle for receiving a sample of said tablets. At least a portion of the receptacle is movable between a collecting position in which the receptacle is configured to be in communication with the interior of the drum, thereby enabling collection of a sample by the receptacle from the drum, and a non-collecting position in which the receptacle is configured to be substantially out of communication with the interior of the drum.
