摘要:
A centrifugal separator includes a counter and an operation/display unit. When performing centrifugation, a runtime select button and a temperature select button in the operation/display unit may be pressed simultaneously to activate the counter, for example. At the beginning of the centrifugation process, the controller detects the start of the operation and increments the count value in the counter. At the end of the centrifugation process, the runtime display unit displays the count value held by the counter for a prescribed time, while the temperature display unit simultaneously displays the preset number of centrifugation processes. The user can visually confirm the count value and the setting for the number of processes before executing the next operation, thereby preventing the user from losing track of the progress and performing an incorrect operation. The counter can also be set to a non-operating state to prevent the count value in the counter from being incremented.
摘要:
A centrifugal separator includes an input section for allowing a user to enter operating conditions of a centrifugal separation of a sample accommodated in a rotor driven by a motor. A memory of the centrifugal separator stores a user ID code and a corresponding user name which are registered in advance by the user. Operation of the centrifugal separator is allowed when a user ID code entered through the input section agrees with the registered user ID code.
摘要:
The invention relates to an automatic separator/extractor and a method of controlling same, with the object, particularly in all manner of fields such as medical science, agricultural science, scientific fields, or pharmaceuticals, of being able to achieve at high speed and accuracy, extraction or separation of precipitate or supernatant at a high quality, accuracy and reliability, above that which can be achieved by manual means. The construction has a conveying device for conveying a mounted vessel along a closed path, a dispensing section for dispensing a reagent or the like into the vessel mounted on the conveying device, a liquid processing section for removing and/or extracting liquid other than a precipitate inside the vessel mounted on the conveying device, a separator for performing separation with respect to the contents inside a vessel which is mounted on the conveying device and/or a vessel which is installed away from the conveying device, a vessel moving device for bringing in and taking out the vessel with respect to the conveying device and/or separator, and an operation/control section for performing operation and control with respect to the conveying device, the dispensing section, the liquid processing section, the vessel moving device, and the separator.
摘要:
In determining the effectiveness of parameters on cells, after treatment of the cells with one or more selected parameters, the results of the treatment can be quickly determined by measuring the number n.sub.0 of cells having a predetermined cell form, subsequently mechanically stressing the cells for a sufficient period of time t to change the cell form substantially, thereafter again measuring the number n of cells having the predetermined cell form, and determining the cell viability .tau.defined by .tau.=t/1n(n.sub.0 /n).
