Description

EP pipe

Technical Field

The utility model belongs to the technical field of the EP pipe, concretely relates to EP pipe.

Background

In 1963, the first Eppendorf microcentrifuge tube in the world was born by the company Eppendorf, Germany, and a new tool is provided for molecular biology micro-manipulation experiments. An EP (Eppendorf) tube, which is a small centrifuge tube, is used together with a microcentrifuge, can be used for separating and preserving micro samples, and can be used as a common tool for molecular biology micro-operation experiments.

Existing EP tubes can be marked with a marker pen at the tube cap or frosted surface of the tube side. Various chemical reagents are often used in the laboratory process, when the chemical reagent elution device is used, the chemical reagents are easy to drop on an EP (EP) tube during operation, and the marking information made by a marker pen on a tube cover or a tube wall is easy to elute by the chemical reagents. The sample is likely to be repeatedly marked in the process of multiple times of elution, when the chemical reagent is splashed on the marked information, the marked information of a plurality of samples even disappears completely, the samples are mixed up, and the samples must be re-extracted, so that the loss of the samples, the reagents and the consumables is caused, and the experiment efficiency is greatly reduced. After the experiment is finished, the extracted sample needs to be stored in a low-temperature environment for a long time. The current EP tube is stored in a low-temperature environment for a period of time or after being frozen and thawed for several times, the mark on the tube cover or the tube wall is easy to fade and finally is unclear, and the common label paper attached to the tube wall is easy to drop, so that a sample with long storage time cannot be identified, and great loss is caused to a laboratory.
