Publication number: 20220297111Abstract: A pipetting device for taking up and dispensing volumes of fluid, which has an ejector mechanism which is actuable by means of an actuating means to eject or release a pipette tip plugged onto the pipetting device. The pipetting device has a coupling mechanism which is configured such that, in the unactuated state, actuating means and ejector mechanism are decoupled, and, when the actuating means is actuated, the latter is coupled to the ejector mechanism, causing a force exerted on the actuating means to transfer to the ejector mechanism. Also, the pipetting device can have a positioning mechanism which, when a pipette tip is not plugged on and the actuating means is unactuated, holds an ejector means, of the ejector mechanism in a basic position which is located between an ejection position and a plug-on position with a pipette tip plugged on.Type: ApplicationFiled: March 2, 2022Publication date: September 22, 2022Applicant: BRAND GMBH + CO KGInventors: Tom GREIN, Markus KURZ

Publication number: 20220212195Abstract: A temperature-control device for receiving of laboratory vessels has a hollow housing with a temperature-control medium. The temperature-control device is thermally conditioned before use, and during use, the conditioned thermal energy is, in a finite time period, either absorbed from the laboratory vessels or transferred to same. The lower part of the housing has a base and the upper part of the housing has, opposite to said base, a receiving region which, in an upward direction, delimits the hollow internal region of the housing. In the receiving region, depressions directed inward serve as receivers for the laboratory vessels to be temperature-controlled. The hollow housing has an air space separated from the internal region. In the internal region, the temperature-control medium flows at least partially around and/or through a horizontally extending absorber element, and said absorber element is connected to the receiving region in thermally conductive manner.Type: ApplicationFiled: July 16, 2019Publication date: July 7, 2022Applicant: BRAND GMBH + CO KGInventor: Steffen GEHRIG
