Description

EP pipe with combined protection function

Technical Field

The utility model relates to a EP pipe field specifically is a EP pipe with combination protect function.

Background

An EP tube, also known as an Eppendorf tube, is often used in chemical and biological laboratories for sample storage, centrifugation and other experimental operations. However, in experiments such as plasmid extraction, additional structures such as separation columns need to be placed in an Eppendorf tube with a common specification, so that the tube cover cannot be closed, the unclosed tube cover is often stirred and broken under high rotating speed or high centrifugal force, and then the tube cover fragments in the centrifuge need to be cleaned after the experiment is finished, and the operation is not proper slightly, so that the situation that the tube cover fragments pollute a test sample is likely to occur. More seriously, after frequent such experiments, the failure to clean up the tube cap pieces thoroughly in the centrifuge can result in severe wear on the centrifuge. However, the common Eppendorf tube has the advantages of simple structure, small specification and low manufacturing cost, and a device for protecting the Eppendorf tube cover is not found in the market.

There is a split EP separation column on the market, comprising a centrifugal EP outer tube without a closure and a separation column with a closure, which after centrifugation allows direct preservation of the sample without taking out the separation column. However, the split structure has poor sealing performance, is not beneficial to operations such as storage and transportation of samples, and is easy to cause leakage and pollution of samples. And the production process of the split type EP tube is more complicated than that of the common EP tube, so that the manufacturing cost is higher, and the split type EP tube is only used for special plasmid separation operation. At present, more school laboratories and comprehensive laboratories still select to adopt a general specification EP tube to match with a separation column for carrying out such experimental operation, and it can be seen that the split type EP separation column has strong use limitation, so that the split type EP separation column is not widely applicable to laboratories of schools, comprehensive laboratories and other laboratories, and has the advantages of wide experimental directions, various experimental types and strong functional flexibility of experimental equipment.

In order to solve the above problems, an EP tube with a combined protection function is proposed in the present application.

The following is a detailed description of the present invention with reference to the accompanying drawings of the case:

referring to fig. 1, 2, 3 and 4, in the operation of storing samples, the EP tube with combined protection function (hereinafter referred to as "EP tube") cap 5 is partially fixed to the top of the tube body 1 in a snap-fit manner, so that the sealing buckle 502 is tightly connected with the tube mouth 3, and the experimental samples are instantly stored in a sealing manner, and the closed state refers to fig. 1. The cover rim 505 facilitates opening the tube cover 5, and under the condition that the air pressure inside and outside the tube body 1 is unbalanced, the anti-skid stripes 506 on the side surface of the tube cover 5 can increase the friction force and reduce the opening difficulty of the tube cover 5. And the cambered surface of the outer side of the guide ring 504 can reduce the abrasion of the inner wall of the pipe orifice 3, and the integral sealing performance of the product can still be ensured after the opening and closing operation of the pipe cover 5 is repeated.

In the centrifugal operation, during the ordinary separation and centrifugal operation, a sample to be separated is added into the tube body 1, the tube cover 5 is closed, and the tube body 1 is placed into a slot of a centrifugal machine, so that the centrifugal operation can be started; during the plasmid separation operation, add the sample in body 1, and put into the separation post in body 1, and put body 1 into the centrifuge slotted hole, buckle the tube cap 5 of adjacent EP pipe each other and connect this moment, can fix the tube cap 5, prevent to damage the tube cap 5 in subsequent centrifugal operation, it should be noted that, should follow the principle of the symmetrical sample of placing in the use of centrifuge, therefore, under the condition that the slotted hole of the adjacent position of EP pipe is vacant that the sample quantity is less, can place the empty EP pipe of the same specification in the adjacent position, and buckle the tube cap 5 part of EP pipe and adjacent empty EP pipe that will have the sample and connect, can provide abundant protection to the tube cap 5 equally, after the centrifugal operation finishes, take out the separation post, and can store the sample to direct closed tube cap 5, the operation flow is simple.
