Patent number: 9914953Abstract: An apparatus for inoculating and streaking a solid growth culture medium in a plate, the streaking using a streaking applicator having a line of resiliently and flexibly supported spaced apart contact surfaces, the apparatus including: (a) an inoculating and streaking station including: a plate work position having a notional action line fixed in two dimensions (x,y) in a predetermined position; and a plate rotation device for rotating a positioned plate to cause streaking; (b) a sensor capable of locating the surface of the medium in a positioned plate to thereby determine for that plate, prior to inoculation and streaking of that plate, the third dimension (z) of the action line; (c) an inoculating device capable of dispensing inoculum, along the action line, on the surface of the medium in the positioned plate; and (d) a streaking device capable of moving the streaking applicator such that its line of spaced apart contact surfaces contacts, along the action line, the surface of the medium in the positiType: GrantFiled: March 10, 2014Date of Patent: March 13, 2018Assignee: LABTECH SYSTEMS LTDInventors: Rajiv Gupta, Stephen Lewis Leckenby, Phillip James Duncan, Ryan Andrew Annear, Daniel Patrick Torpy, Chong Kean Ooi, Michael John Tomlinson, Leon Raj, Graeme John Cross, Kenneth Andrew Nicoll, Wayne Richard Cheetham, Michael Craig Lovett, Colin William Potter
