LABORATORY EQUIPMENT HOLDER

Abstract

Laboratory equipment holder to mount and position glass flasks in a simple and secure manner. The laboratory equipment holder includes of a component on which at least one holding device is attached and both the component and also the holding device and the connection between the component and holding device can be mechanically loaded with at least one filled piece of laboratory equipment, and the component includes on one of its sides at least one recess. At least the end thereof within the component is embodied in an at least semicircular manner and at least the smallest diameter of the semicircular section of the recess is smaller than the largest diameter of the truncated conical neck of the piece of laboratory equipment and/or is smaller than the largest diameter of the beaded edge-like enlargement of the neck of the piece of laboratory equipment.

Claims

1. A laboratory equipment holder composed of a component and at least one piece of laboratory equipment having at least one neck, which piece of laboratory equipment is arranged such that it is suspended on the laboratory equipment holder, wherein the outer shape of the neck is in the for of a truncated cone with the larger diameter of the truncated cone towards the end of the neck, and/or a beaded edge-like enlargement around the neck is present towards the end of the neck, and wherein at least one holding device is attached to the component, and both the component and also the holding device and the connection between the component and holding device can be mechanically loaded with at least one filled piece of laboratory equipment, and the component comprises on one of its sides at least one recess, and the laboratory equipment is introduced solely from the opening side of the recess, and wherein at least the end of the recess within the component is embodied in an at least semicircular manner, and at least the smallest diameter of the semicircular section of the recess is smaller than the largest diameter of the truncated conical neck of the at least one piece of laboratory equipment and/or is smaller than the largest diameter of the beaded edge-like enlargement of the neck of the at least one piece of laboratory equipment.

2. The laboratory equipment holder according to claim 1 in which the component has a rectangular, round, oval, square, or triangular shape.

3. The laboratory equipment holder according to claim 1 in which the thickness of the component is smaller, in particular significantly smaller, advantageously more than 5 times smaller, than the other dimensions of the component.

4. The laboratory equipment holder according to claim 1 in which the longer sides of the component are longer, advantageously more than 5 times longer, than the short sides, and the thickness of the component is smaller, advantageously more than 5 times smaller, than the length of the short sides.

5. The laboratory equipment holder according to claim 1 in which two holding devices are present on opposite sides of the component.

6. The laboratory equipment holder according to claim 1 in which one or more pieces of glass laboratory equipment, in particular glass flasks such as Erlenmeyer flasks or round-bottom flasks, are positioned in one recess each such that they are suspended simultaneously next to and/or above one another and/or in different sizes and shapes.

7. The laboratory equipment holder according to claim 1 in which the component is composed of metal, such as stainless steel or aluminum, or of plastic or of composite materials, wherein the materials of the component are advantageously resistant to chemicals.

8. The laboratory equipment holder according to claim 1 in which the holding device is present in the form of a rod-shaped holding device, wherein the holding device is connected to the component in a non-positive fit and/or material bond.

9. The laboratory equipment holder according to claim 1 in which at least one, advantageously multiple, such as two to five, recesses are present in the component, wherein the recesses are advantageously arranged at an equal distance to one another and with the same dimensions.

10. The laboratory equipment holder according to claim 1 in which at least two recesses with different dimensions are present in the component and, in the case of more than two recesses, the recesses are present at different distances to one another.

11. The laboratory equipment holder according to claim 1 in which one, multiple, or all recesses comprise in a vertical direction a chamfer and/or comprise rounded edges and corners at the openings of the recesses.

12. The laboratory equipment holder according to claim 1 in which the distance between the non-semicircular, parallel sides of the recesses has dimensions that are between 1% and 10% smaller than the largest diameter of the truncated conical neck of the at least one piece of laboratory equipment and/or than the maximum diameter of the beaded edge-like enlargement of the neck of the at least one piece of laboratory equipment.

13. The laboratory equipment holder according to claim 1 in which the at least semicircular section of the recess constitutes a circular arch segment between 180 and <360, preferably between 190 and 310, formed by the component material.

14. The laboratory equipment holder according to claim 1 in which the recesses are provided with inserts.

Description

[0062] The invention is explained below in greater detail with the aid of an exemplary embodiment.

[0063] Wherein:

[0064] FIG. 1 shows a laboratory equipment holder according to the invention and

[0065] FIG. 2 shows a possibility for the arrangement of laboratory equipment holders according to the invention positioned above one another

EXAMPLE 1

[0066] A rectangular component made of stainless steel with the following dimensions: length=480 mm, width=70 mm, height=5 mm comprises on the short sides, each soldered on in the middle, a rod-shaped holding device made of stainless steel on each side, with the following dimensions: length=35 mm, diameter=12 mm. Located at a respective distance of 48 mm from the short sides is in each case the center of the first recess, and respectively located at a distance of 96 mm from this center of the recesses are the centers of three additional recesses. The recesses all have a width of 32 mm, and the smallest diameter of the semicircular sections at the end of each recess has a diameter of 32.48 mm. The corners and edges of the rectangular component are respectively rounded, and the recesses each comprise downwards in a vertical direction a chamfer with a slope of 1/10.

[0067] Round-bottom flasks with the following dimensions: diameter=60 mm, total height=105 mm, height of the neck on the round-bottom flask=45 mm, nominal volume=100 mL with an NS 29/32 ground glass joint in the interior of the neck in accordance with DIN can be hung in the five recesses, which flasks are introduced into the recess from the front at the lower section of the truncated conical neck located away from the opening, and are then lowered.
