20160136594 | Laboratory Stirrer - A lab stirrer comprises a housing, a stirring shaft rotatably supported about an axis in the housing and a drive to drive the stirring shaft to make a rotary movement about the axis. A blocking device is provided to block the stirring shaft against a rotation about the shaft axis. | 05-19-2016 |
20160136539 | ROTARY EVAPORATOR - The invention relates to a rotary evaporator for the vacuum distillation of a liquid, comprising an evaporating flask and a cooler, which is arranged downstream of the evaporating flask and is connected to the evaporating flask by means of a vapor feeder, wherein a rotor having a mechanical foam breaker is provided inside the vapor feeder. | 05-19-2016 |
20140144767 | METHOD AND APPARATUS FOR VACUUM DISTILLATION - The invention relates to a method for the vacuum distillation of a liquid, in particular by means of a rotary evaporator, wherein at least one fraction of the liquid is evaporated at a reducing pressure, a vapor temperature correlating with a boiling temperature is determined by means of a temperature sensor and a pressure present at the time of the determination of the vapor temperature and correlating with a boiling pressure is determined and a minimal pressure, which may not be undercut in the distillation, is automatically determined by using the determined vapor temperature and to the determined pressure. | 05-29-2014 |
20130153397 | DISTILLATION APPARATUS - The invention relates to a distillation apparatus, in particular a distillation apparatus configured as a piece of laboratory equipment, having a distillation vessel for receiving a mixture to be distilled, wherein a removal device is provided which is configured for the automated removal of a distillation residue from the distillation vessel. | 06-20-2013 |
20100193345 | ROTARY EVAPORATOR - The invention relates to a rotary evaporator comprising a rotary drive having a hub and a clamping insert with a sleeve-like basic shape, in particular a clamping sleeve, for the clamping of a steam leadthrough formed as a hollow glass shaft in the hub of the rotary drive, wherein the clamping insert has a longitudinal axis and a first and a second axial end, wherein the clamping insert has two clamping sections which are arranged spaced apart from one another in the longitudinal direction and which each have an outer cross-section tapering toward the first end and of which the clamping arrangement arranged closer to the second end has a larger maximum outer cross-section. | 08-05-2010 |
20100193140 | ROTARY EVAPORATOR - The invention relates to a rotary evaporator having an apparatus for the securing of a ground joint including a ground sleeve and a ground core between an evaporator flask and a steam leadthrough, wherein the securing device has a fastening section at the ground core side and a snap connector at the ground sleeve side and pivotably supported at the fastening section at the ground sleeve side between a release position and a holding position in order selectively to release or firmly hold the piece of laboratory equipment at the ground sleeve side. | 08-05-2010 |
