Description

Liquid phase sampling small bottle cleaning spray head

Technical Field

The utility model relates to liquid chromatography sample injection vial cleaning equipment, in particular to a liquid chromatography sample injection vial cleaning spray head.

Background

In recent years, liquid chromatography is widely used in the fields of medicine research and development and product detection, the use and dependence of various research and development enterprises and production enterprises on liquid chromatography are in an obviously rising trend, and the use cost of sample injection vials is greatly increased. In order to save cost, the sample injection vial is generally reused in a laboratory, and the used sample injection vial is recycled and cleaned for reuse, so that the situations of cross contamination and incomplete cleaning exist. The traditional mode of manually cleaning the small bottle wastes time and labor, is complex to operate, and is easy to retain residual impurities.

SUMMERY OF THE UTILITY MODEL

The utility model efficiently solves the problems of cross contamination and residue caused by cleaning sample injection small products, more efficiently realizes resource reuse, and provides a liquid phase sample injection small bottle cleaning spray head.

The technical scheme of the utility model is as follows:

a liquid chromatography sample injection vial cleaning spray head comprises a cleaning spray head box (1) and a vial collecting box (2), wherein the cleaning spray head box (1) sequentially comprises a gauze filtering layer (1 a), an activated carbon filtering layer (1 b) and a cotton filtering layer (1 c) from top to bottom; the upper part of the cleaning spray head box (1) is provided with a water pipe connector (4) for connecting a water pipe (5), and the lower part is provided with a cleaning head (3); the other end of the water pipe (5) is connected with a water pump through a water pump connector (6).

Furthermore, the cleaning sprayer box (1) is provided with 100 plug-in cleaning heads (3) which are 10 transverse and 10 longitudinal, and the cleaning heads (3) can extend into the liquid phase bottle; the vial collection box (2) can contain 100 liquid phase vials, which are separated by a partition. The cleaning spray head box (1) is made of 304 stainless steel materials, and the sealing performance is high.

Advantageous effects

1. The cleaning nozzle has good integral sealing effect, fully utilizes water pressure to impact the interior of the sample injection vial, and can deeply penetrate into the sample injection vial for cleaning, thereby reducing the occurrence of cross contamination and residual condition.

2. The working efficiency of experimenters is improved, the waste of water resources is reduced, and the available resources are fully utilized.

wherein 1 is a cleaning spray head box; 2 is a vial collection cassette; 3 is a cleaning head; 4 is a water pipe connector; 5 is a water pipe; 6 is a water pump connector; 1a is a gauze filtering layer; 1b is an active carbon filter layer; 1c is a cotton filter layer.

Detailed Description

The utility model is further illustrated by reference to specific examples. These examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In addition, any methods and materials similar or equivalent to those described herein can be used in the methods of the present invention. The preferred embodiments and materials described herein are intended to be exemplary only.

The cleaning device is made of 304 stainless steel, has stable performance, is light and convenient, is internally provided with three water quality filtering layers, can better ensure the cleanness of a cleaning sample injection vial, and simultaneously reduces the occurrence of the problems of residue, cross contamination and the like of the vial so as to influence the accuracy of experimental data.

Taking the analysis department of the company as an example, for the long-term use of conventional sample injection vials and the repeated use, the risk degree of cross contamination is considered respectively by comparing the cleaning device with the conventional cleaning device without the device.

Example 1

And (3) a sample injection vial cleaning device is not installed, the sample injection vial cleaning device is soaked in a water bucket by using a detergent, ultrasonic cleaning is carried out, then ultrasonic cleaning is carried out continuously after the sample injection vial cleaning device is soaked in clear water, and the operation is repeated. In this way, firstly, the inside of the vial cannot be effectively flushed, secondly, cross-contamination is likely to occur, and thirdly, the inside of the vial still remains. The continuous use of the method easily causes inaccuracy of experimental data, thereby causing the occurrence of conditions affecting the experimental progress.

After the installation, will all wait to wash and advance a kind vial and arrange the containing box in unified putting, add the shower nozzle box with the cleaner in, connecting pipe will insert interior intubate in proper order in the vial slow boiling water wash can, repeatedly wash a kind vial for a long time with the flowing water that has the cleaner of circulation, the inside and outside of vial all has the washing effect, the waste liquid that washes is discharged at any time, also higher probability's reduction is remained when can not causing cross contamination appearance, more effectual assurance experimental data accuracy.

Example 2

The injection vial cleaning device is not installed to clean the injection vial to be cleaned, the volume of water is increased due to the fact that liquid is not easy to enter the injection vial, the effect does not reach the expected effect, time is wasted while unnecessary water resources are wasted due to repeated water changing, and the operation is inconvenient,

after the device is installed, all sample injection small bottles to be cleaned are placed in the device and only need to be repeatedly washed, the water consumption with the same volume can exert the maximum cleaning effect, and meanwhile, the water can be saved.

And (4) conclusion: it has more efficient embodiment to compare in conventional cleaning mode in the saving utilization of the cleaning performance and the water resource of conventional appearance vial belt cleaning device to advance a kind, advance a kind vial belt cleaning device simultaneously and also can filter the quality of water for washing when wasing, when guaranteeing the cleaning performance, more efficient has avoided the remaining appearance of secondary pollution, advance a kind vial belt cleaning device also to have more economical change in the water consumption moreover, on improving the same water consumption greatly, and then further resources are saved when having more efficient cleaning performance.
