Abstract
Description
Technical Field
[0001] The utility model relates to the field of laboratory technical equipment, in particular to a shorter pipette. Background Art
[0002] With the rapid development of the biological cell industry, pipettes, as one of the most commonly used consumables in biological laboratories, have a large market demand. The sterile glass pipettes of 5, 10, 15, 25 ml and other specifications currently sold on the market are about 35-50 cm long. For biosafety, the biosafety cabinet must be in a semi-closed state when in use, that is, the front window glass can only be pushed up 25-30 cm, and the experimenter can only put his hands into the biosafety cabinet for operation. When reagents need to be dispensed or containers need to be replaced, pipettes and pipettes must be used for pipetting operations. However, pipettes with a length of 35-50 cm are very inconvenient to operate due to the relatively small space in the biosafety cabinet and the limited arm length of the operator. Utility Model Content
[0003] The technical problem to be solved by the utility model is that the space of the biological safety cabinet is relatively narrow and the arm length of the operator is limited, so it is inconvenient to use a long pipette.
[0004] In order to solve the above technical problems, the utility model adopts the following technical means:
[0005] A shorter pipette comprises a pipette body; the pipette body comprises a liquid storage bag, a straw is provided at the front end of the liquid storage bag, a joint is provided at the rear end of the liquid storage bag, one end of the straw is connected to the top of the liquid storage bag, a suction head is provided at the other end of the straw, the suction head is 1 cm long, the straw is 15 cm long, the liquid storage bag is 5 cm long, and the joint is 3 cm long.
[0006] As a preferred embodiment, a further technical solution of the utility model is:
[0007] The suction head is in the shape of a conical tip, and an opening is arranged on the top of the suction head.
[0008] The length of the pipette body is 24 cm.
[0009] The outer diameter of the straw is 0.6 cm.
[0010] The straw is made of glass.
[0011] One end of the connector is connected to the bottom of the liquid storage capsule, and the other end of the connector is provided with a connection port, the outer diameter of the connection port is 0.5 cm, and the connection port can be connected to the muzzle of a pipette.
[0012] The diameters of the upper and lower connecting ports of the liquid storage bag are 0.5 cm, and the diameter of the middle cavity of the liquid storage bag is 3 cm.
[0013] The liquid storage bag and the straw are marked with scales, and the scales show volume numbers.
[0014] An auxiliary fastening ring is arranged at the joint, and the auxiliary fastening ring is a rubber ring.
[0015] The utility model discloses a shorter pipette. The material of the device can be imported high-quality polystyrene, which is sterilized by gamma rays and marked with scale lines. The device is used for cell culture in biological laboratories and other businesses, can accurately absorb liquid reagents, and has a moderate length, is suitable for operation in a biological safety cabinet with a small space, and provides convenience for a large number of workers in the biological cell industry. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a structural schematic diagram of a specific embodiment of the utility model.
[0017] Explanation of reference numerals: 1 - suction tip; 2 - suction tube; 3 - liquid storage capsule; 4 - connector. DETAILED DESCRIPTION
[0018] The present invention will be further described below in conjunction with the embodiments.
[0019] See also Figure 1 It can be seen that the utility model patent is a liquid transfer device. When in use, the 1cm long pipette head 1 can accurately absorb the reagent, the outer diameter is 0.6cm, the length of the straw 2 is 15cm, and it can be inserted into the liquid storage device with a smaller bottle mouth, the outer diameter of the 5cm long liquid storage capsule 3 is determined according to the specifications, and the length of the connector 4 is 3cm, which can be tightly connected with most electric suction aids on the market.
[0020] See also Figure 1 It can be seen that the utility model is a liquid transfer device. The material of this liquid transfer device (pipette) is glass, which is resistant to acid and alkali, and resistant to high temperature (can be sterilized at high temperature). This device is divided into four parts. The first part is the suction head 1 that contacts the liquid storage device. The suction head 1 is 1 cm long and is designed with a conical tip. The second part is the straw 2 that needs to be inserted into the liquid storage device. The outer diameter is 0.6CM (to facilitate liquid storage devices of various calibers) and the length is 15cm. The third part is the liquid storage capsule 3 of the thick liquid storage device. The outer diameter can be set to different specifications according to needs, and the length is 5cm. The fourth part is a joint 4 for connecting the pipette gun, with an outer diameter of 0.5cm (designed according to the caliber of the pipette gun) and a length of 3cm. The length of this device (pipette) is 24cm, and there are corresponding scales on the device to display the volume.
[0021] Since the above is only a specific implementation method of the present utility model, the protection of the present utility model is not limited thereto, and any equivalent changes or substitutions of the technical features of the technical solution that can be thought of by any technician in this technical field are included in the protection scope of the present utility model.
