用四季豆进行的实验表明，分子量为20000的CarBowax聚乙二醇经纯化后，可用作控制植物营养液渗透压的试剂，而不会干扰正常的代谢过程。在钠电极和热电偶干湿计上，离子与CarBowax之间的相互作用导致后者轻微解离。
Experiments with kidney beans indicate that Carbowax polyethylene glycol, molecular weight 20,000, upon purification, may be used as an agent to control the osmotic pressure of plant nutrient solutions without the hazard of interference with normal metabolic processes. With the sodium electrode and the thermocouple psychrometer, interaction between ions and Carbowax is shown to lead to a slight dissociation of the latter.
