The conductive Pipette Tips are specially designed for automatic workstations and are made of medical grade conductive polypropylene (PP) material, and the tips are conductive. After the conductive tip is adapted to a specific automatic pipetting workstation, it can detect the liquid level, making the automatic sample addition more intelligent and precise. pipette tips 10 ml,20 ul pipette tips,5 ml pipette tips, 200 ul pipette tips Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yypipette.com
1. The plant ash is an alkaline fertilizer and should not be mixed and mixed with ammonium sulfate and ammonium nitrate. Ammonium sulfate, ammonium nitrate and ammonium hydrogencarbonate are all ammonium nitrogen fertilizers. If they are mixed with grass ash, the nitrogen in the nitrogen fertilizer will be turned into ammonia gas to run away. When using ash and ash together with acid fertilizers, be careful not to mix them together.
Second, the grass ash should not be mixed with human excrement and livestock excrement. It is a mistake to use rural ash to pour grass ash into a pit or pig pen. Livestock excrement, human excrement, etc. are a kind of delayed-effect acid nitrogen fertilizer. For example, the alkaline ash is poured into acid-containing livestock excrement and human excrement, and the acid-base neutralization causes ammonia to volatilize, thereby reducing fertilizer efficiency. When the plant ash is mixed with livestock excrement for 1 week, the ammonium nitrogen in the excreta can be lost by more than half. The longer the mixing time, the more nitrogen loss.
Third, the nutrients in the plant ash are easily soluble in water. In order to preserve the ash, it should be stored separately in a place such as a ash warehouse or a gray shed to shelter from the wind and rain. After the rain, the ash will be seriously damaged.
4. Grass ash can not be mixed and mixed with superphosphate, which will reduce the effectiveness of phosphorus.
Transparent automatic Pipette tips can also be called robotic pipette tips or micro tips; Yongyue Medical's pipette tips have been sterilized and are packaged with 96 pieces per box, which is easy to carry and operation; compatible for Beckman, Tecan, Rainin to achieve automatic pipetting performance and ensure the consistency of pipetting.
The robotic tip is made of imported polypropylene (PP) material, with high transparency. The surface is treated with a special process and has super-hydrophobicity to ensure the accuracy of experimental data. The product is automatically produced in a 100,000-level purification workshop, free of DNase, RNase, and pyrogen-free.
In rural areas, straw and firewood of various crops are used as fuel, and the ash after burning is called ash. This is the main source of potash in rural areas. It can not only be used as a base fertilizer for sweet potato, wheat and other crops, but also can be used as a fertilizer on beans. The composition of plant ash is quite complicated. The ash elements contained in plants are found in grass ash, such as phosphorus, potassium, calcium, magnesium and sulfur. Among them, potassium, phosphorus and calcium are abundant, and potassium is generally 5%-10%. Regardless of the ash content of the plant, the potassium contained is soluble, quick-acting, and can be directly absorbed and utilized by the crop. Grass ash is an alkaline fertilizer. Pay attention to the following four points during use and preservation:
