Claim Text:
1. A laboratory instrument for homogenizing samples, wherein said laboratory instrument oscillates said samples within sample holders by using a motor to rotate a hub with strikers that are positioned to impact said sample holders upon rotation, with temperature control of said samples, comprising: a. a chamber for storing a thermal mass; b. a thermal mass; c. a sample chamber; d. a means to provide forced convection with a flow of air by said thermal mass; e. a means for modulating said flow of air into said sample chamber; f. at least one temperature sensor; g. a motor speed sensor; h. an electronic circuit in communication with said at least one temperature sensor and with said motor speed sensor; and i. said electronic circuit providing a means for controlling the operation of the instrument; wherein said electronic circuit comprises a controller configured to control said motor and modulate said flow of air using feedback from said motor speed sensor and said at least one temperature sensor.
