Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a pipette holder, and more specifically, it is capable of holding a pipette without tipping over or losing balance even when a relatively heavy object such as a safety pipettor is attached to the pipette. Regarding pipette holders.

[Conventional technology]

In chemical laboratories, pipettes are often used, but in particular those with a relatively heavy rubber bulb on the top for sucking liquid called a safety pipettor 6 are unstable and should not be used. is difficult to handle. For example, if you lean it against the inner wall of a beaker, as is often done, there was a problem in that it would easily lose its balance and fall and be destroyed. For this reason, the pipettor had to be removed each time it was placed horizontally on the laboratory bench. Furthermore, Japanese Utility Model Application No. 58234/1983 discloses a whole pipette stand in which a square or disc-shaped plate is provided with a large number of holes of different diameters for use with whole pipettes. However, this whole pipette stand was not originally designed to hold a pipette with a kind of relatively heavy rubber bulb for sucking liquid called a safety pipettor on the top, and no consideration was given to this purpose at all. As is clear from FIGS. 3 and 4 of the accompanying drawings, it is clear that the user easily loses balance and falls over. In other words, depending on the type of pipette, it is necessary to make many holes in a rectangular plate or a disc-shaped plate, and a plate with many holes drilled in the upper part is inevitably formed. They have poor balance and are prone to falling. Moreover, depending on the type of pipette, a large number of holes must be provided in a rectangular plate or a disc-shaped plate, which is extremely complicated.

[Problem that the idea aims to solve]

The problem of this invention is to be able to hold a relatively heavy object such as a safety pipettor without losing its balance even when it is attached to the top of the pipettor, and to be able to hold it regardless of the type or size of the pipettor. The purpose is to provide a pipette holder with good workability.

[Means to solve the problem]

The present invention was developed in view of the above, and its gist is a vertical pipette holder consisting of a base, a support, and a pipette insertion port, the pipette insertion port being a megaphone or funnel-shaped wide-mouthed pipette holder. An element having a shape consisting of a part and a narrow opening is removably fitted into a ring fixed to the support, and the narrow opening of the element is
This is a standing pipette holder characterized by forming hanging legs and supporting a pipette standing upright without greatly tilting it. Hereinafter, the configuration requirements of the present invention will be broken down and explained with reference to the drawings. Pedestal (i) The pedestal 1 serves as a support for the pipette holder, and the shape of the pedestal can be arbitrarily selected according to need, but the pipette holder can be used to hold pipettes in flasks, beakers, etc. Since it is often used to hold 5, it is preferably circular. Of course, the pedestal can also take other shapes such as a donut shape or a disk shape. Of course, if there is no need to move the pedestal, the pedestal may be directly fixed to a desk or the like. (ii) The size of the pedestal is not particularly limited and can be determined as appropriate in consideration of the size of the container used. (iii) As the material of the pedestal, stainless steel alloy, aluminum, plastics, etc. are preferably used. Support (i) The height of the support is not particularly limited, and can be determined as appropriate by taking into account the size of the container used, such as the pipette. Also, depending on the size of the container,
It is also possible to devise measures such as providing a height adjustment knob 3 or the like so that the height can be adjusted. (ii) As with the pedestal, the material of the support is preferably stainless steel, aluminum, plastic, etc. (iii) The method of attaching the support to the pedestal can be welding, adhesive, screwing, etc., depending on the material of each. Pipette Inlet (i) The shape of the pipette outlet is the most distinctive feature of the present invention.As shown in FIG.
Basically, it is arranged with the wide mouth facing upwards and the narrow mouth facing downwards. In addition, instead of fixing the pipette socket directly to the support, a ring approximately concentric with the pedestal is fixed to the support, and an element of the pipette socket having a megaphone or funnel shape as described above is attached to this ring. They may be removably fitted together. In this way, FIG. 1 shows a device in which the pipette insertion port is provided so that it can be separated from the ring. With such a structure, it becomes easy to take in and take out the pipette. (ii) The lower part of the pipette receptacle has a narrow opening, preferably further forming a hanging leg. This part is a part that supports the pipette, and is preferably thin enough (approximately 70° or more) to prevent the pipette from tilting significantly when it is stood up. (iii) The upper part of the pipette insertion port is a wide mouth part. Note that this portion only needs to serve as a guide when taking the pipette in and out, and does not necessarily need to be provided as long as the size of the ring is sufficiently large compared to the thickness of the pipette. (iv) It is preferable that the ring approximately concentric with the pedestal be set smaller than the pedestal in order to maintain balance. (v) The material of the pipette receptacle is preferably made of stainless steel alloy, aluminum, plastics, etc., and combinations thereof. (vi) The method of attaching the column and pipette socket pedestal can be welding, adhesive, screwing, etc., depending on the material of each.

[Effect of the idea]

Since the present invention is constructed as described above, even if a relatively heavy object such as a safety pipettor is attached to the top of the pipettor and stands up against it, it will not lose its balance, and it will not lose its balance. The pipette can be held regardless of the type and size of the pipette without the need for a pipette. Also,
The pipette insertion port is removably fitted into a ring fixed to the support column, and is provided so that it can be separated from the ring, making it easy to insert and remove pipettes, providing a pipette holder with good workability. be done.
