WebMar 23, 2024 · After discarding the supernatant, Milli-Q water (25 mL) was added to redissolve the gelatin at 50°C under magnetic stirring, followed by adjusting the pH of the gelatin solution to 2.5 with 1 M HCl. Acetone (80 mL) was subsequently added (4 mL/min) under high-speed (1,200 rpm) stirring to allow formation of gelatin nanospheres. WebJun 25, 2024 · Here is the short answer. Deionized water and ultrapure water are both types of extremely pure water, but they are produced in two distinctly different ways. DI water is created through the process of deionization. UP water is produced by a combination of purification technologies, such as RO filtration, EDI module, UV sterilization and ultra ...
Web"Milli-Q water is water that has been purified using an ion exchange cartridge. The purity of the water is monitored by measuring the conductivity. The higher resistance, the fewer ions in the water. A value greater than 18.2 MΩ cm-1 (@ 25 °C) is desirable. As a final step, the water is normally dispensed through a 0.22 μm membrane filter."
