How to make secondary distilled water in laboratory. How to use the preparation equipment? What about the equipment? Clear the attachment, thank you

Simply put, the distilled water produced by tap water distillation and the first distillation is called double distilled water. This instrument is a traditional way to produce pure water, which consumes electricity and water (by electric heating and water circulation cooling, there is a lot of wastewater to prevent scaling), and the market price is about 2000 yuan.

The reverse osmosis deionized water machine produced by Shanghai Miaokang Industrial Co., Ltd. adopts advanced reverse osmosis water-saving technology to directly convert tap water into deionized water that meets the first-class water consumption index of the laboratory, which can fully meet your water demand. Water production is faster and the subsequent cost is lower. If you are interested, please visit Baidu's website for details.
