摘要:
A system including a flexible, removable tube holder that flexes to fit either a straight rack or a centrifuge rotor slot. The system provides for the elimination of manual recording of the individual tubes, and provides for the transference of the tubes from the rack to the centrifuge and back, as a group.
摘要:
A centrifuge having two arcuate slots to receive resilient, bendable mounting flanges that each carry a plurality of test tubes in side by side relation. The resilience of the mounting flanges enables them to flex and assume either the curvature of the slot, or a linear configuration enabling the flanges to be suspended in a flat condition, such as on a test rack. The arrays of test tubes is attached to the flanges via living hinges that enable the flexing to occur. The advantages are that simplified identification of individual test tubes, as well as reduced likelihood of intermixing of spillage are realized.
摘要:
The present invention includes a system and method for the management of specimens ordinarily manipulated via tubes. The invention may include a flexible, removable tube holder that is linear when placed in a rack and curved when placed into a centrifuge rotor. The system provides for the elimination of manual recording of the individual tubes, and also provides for the transference of the tubes from the rack to the centrifuge and back in a group.
摘要:
The present invention relates to an apparatus for substantially horizontally oscillating one or more multi-well plates containing a liquid, a solid, or a mixture thereof that operates to thoroughly disrupt solid substances in multi-well plates. The apparatus provides oscillation of plates in a horizontal direction through the use of springs and rotating mechanical components. The apparatus includes a circular rotating ring having a toothed circumference that rotates horizontally, plate holder, and a spring attached to the housing and in constant contact with the plate holder. The apparatus can be used in a cold room or placed in a refrigerator to keep the substances at low temperature and to eliminate noise when the disruptor operates.
摘要:
A method of mixing together liquids or liquid/solid combinations, and mixing apparatus/universal combine utilizing a vertical spinning container or vessel having a rib, or a cross rib in its bottom wall. The container is spun about a vertical axis with no wobbling component to the motion. Meshed elements are used for high shear mixing. Start/stop routines, and variable acceleration/speed values are used, to facilitate complete mixing. Use of ‘impeller’ blade stirrers is completely eliminated.
摘要:
A device for biological and medical tests wherein tested media placed in test tube is subjected to mixing, or homogenization, or resuspention, or disintegration, or disruption, and further centrifugation of these media, including: a rotor having a replaceable closure, driving means having substantially vertical shaft, striking means capable to engage or disengage test tubes and means for moving the rotor up and down, along a the shaft that provides engagement or disengagement of said striking means with said tubes.
摘要:
A mixer is intended for mixing substances, resuspending pellets and disintegrating living cells, such as yeast cells. The mixer includes a tube holder and an electric motor with striking attachment(s). The main part of the holder is rigid rings coaxial with and located subsequently along the motor shaft. Each ring has a number of holes the tubes sit in. Diameters of the holes are larger then diameters of the tubes, so that there are gaps between the tubes and the rigid rings. The attachment(s) of the motor is disks with blades, affixed to the motor shaft. When the motor shaft rotates the blades strike against the tubes. Struck tubes are repelled by the rigid ring (due to a gap between the tubes and rings), get a new strike from the blades and so on. As a result, the substance inside the tube receives a turbulent motion which provides mixing, resuspending and disintegrating effects.
摘要:
A hand operated device for storing, measuring, and dispensing powder or granular materials, with a simplified structure and reduced number of parts. The housing integrates a material storage container with a dispenser, comprising: special compartments and sound damper, made of elastic porous material that makes use of the device quiet; a one touch assembly and disassembly of an inner space of the device where the dispenser is located; structural elements for dispensing a predetermined volume of the material or its fraction, including a way to reduce the length of the working stroke of the dispensing mechanism; wall extensions to prevent bridges of sticky particles forming; separating walls to allow delivery a more than one material stored in one device including more than one material transporting mechanisms inside the dispenser; and structural elements providing exact measuring, and sifting or pouting of the materials.
摘要:
An apparatus for substantially horizontally oscillating one or more vessels containing a liquid, a solid, or a mixture thereof that operates to thoroughly disrupt and mix solid and liquid substances in vessels, like test tubes. The apparatus provides superior mixing through oscillation of the vessels both horizontal and vertical directions through the use of one or more springs and rotating mechanical components. The apparatus includes a circular rotating ring having a toothed circumference that rotates horizontally, at least one vessel support having a compartment configured to hold the one or more vessel vessels and a spring attached to the housing and in constant contact with each of the one or more vessel supports.
