Background
With the increasing importance of people on food safety and environmental problems, the problem of pesticide residue is more and more concerned by people; various specialized testing facilities and laboratories are also increasingly emerging.
The pesticide residue (hereinafter referred to as "pesticide residue") is a generic term for a pesticide parent substance, a derivative, a metabolite, a degradation product and an impurity remaining in the environment, an organism and a food after the pesticide is used. The pesticide residue of agricultural products such as vegetables, melons and fruits, tea leaves and the like exceeds the standard, mainly some forbidden organophosphorus pesticides, carbamate pesticides and the like are used, and in addition, with the development of science and technology, various novel pesticides emerge endlessly, and the detectable pesticide residues reach hundreds. Acute poisoning accidents of people and livestock can be caused by eating food containing a large amount of highly toxic and highly toxic pesticide residues; if the agricultural and sideline products with pesticide residues exceeding the standard are eaten for a long time, chronic poisoning of people and animals can be caused, various diseases can be caused, and even the conditions of cancers, fetal deformity and the like can be caused. Therefore, in order to ensure the safety of the food, the food needs to be subjected to pesticide residue detection by periodic or random sampling before entering the market for circulation; in addition, soil, water and the like also need to be sampled for pesticide residue detection, so that the food safety is ensured.
The method comprises the following steps of adding an extracting agent (water, ethanol, acetonitrile, acetone and the like) into a weighed sample, extracting, and performing qualitative or quantitative analysis by a high-efficiency gas or liquid chromatograph to obtain a detection result of a corresponding index; in the extraction process, in order to guarantee that the extraction is abundant, often need to vibrate to schottky bottle, test tube etc. that are equipped with sample and mixed liquid and shake evenly, vibrate and shake and generally adopt reciprocating type shaking table to accomplish when even.
In order to reduce cost and improve efficiency, the laboratory often processes samples in batches, shaking a plurality of reagent bottles (reagent bottles generally comprise a larger 250mL Schottky bottle and a smaller 50mL disposable plastic test tube) on a shaking table at one time; ordinary shaking table adopts two or many mobilizable rod irons (outside cover has the bubble cotton) to press from both sides schottky bottle or reagent bottle between two rod irons and fixed, and the rod iron both ends are screwed and are fixed on the guide rail on shaking table both sides, and operating personnel is easy fixed not tight when the fixed rod iron of manual screwing, shakes even in-process and probably not hard up and lead to schottky bottle, test tube etc. to lose fixedly shaking, and then leads to the schottky bottle, the dangerous condition such as test tube falls or damaged to take place. The fixing mechanism on the reciprocating type shaking table is troublesome and unstable to operate when clamping the Schottky bottle, and has certain potential safety hazard.
In addition, the schottky bottle often has the problems that the bottle mouth is contaminated with impurities when in sample weighing, the inside of the bottle cap is damaged or contaminated with impurities, the strength of an operator is small, the bottle cap is not screwed down, and the like, so that liquid leakage is caused in the shaking-up process of falling and shaking of the schottky bottle; once leakage occurs, the pollution of the shaking table and the air in the laboratory can be caused, and the error of the detection result is more likely to increase. Relatively speaking, no matter the disposable plastic test tube is shaken evenly in a standing posture or a standing posture, the disposable plastic test tube is not easy to leak liquid.
Because reagent generally can not fill up in the schottky bottle, reagent liquid level exists the certain distance to the bottleneck, upright placing the schottky bottle and vibrate and shake even can effectively prevent, but operating personnel generally think upright placing shake even extraction with vibrate the effect not as with the schottky bottle put down shake even effectual to, upright placing when shaking even schottky bottle take place more easily not hard up, collision each other and lead to the bottle to break, the loss and the pollution that cause are bigger.
