Automatic microbial transfer device
Abstract
An apparatus is disclosed for automatically transferring a predetermined amount of inoculated culture from a first container into a second container having a sterile culture therein. The containers rest on the top of a pivoted support surface, and a horizontally disposed conduit connects them. The support surface is pivoted from its normal horizontal position by a solenoid which is activated under the control of an electrical timer. When the solenoid is inactive, the catch is connected to the first end of the support surface to hold it in its normal horizontal position. When the solenoid is activated, the catch releases the support surface into a freely pivoting state; a weight disposed on the second end of the support surface tips the support surface from its normal horizontal position causing the predetermined volume of inoculated culture to flow from the first container through the horizontally disposed conduit and into the second container having sterile culture therein.
