Under the same flow rate, higher pressure produces lower frequency, fewer pressure fluctuations, better product quality, and greater equipment durability. At 30,000 psi, a laboratory high pressure homogenizer, can reach fluctuation levels of less than 10 Hz, as opposed to 60 Hz from a normal homogenizer. | Under the same flow rate, higher pressure produces lower frequency, fewer pressure fluctuations, better product quality, and greater equipment durability.

High pressure piston materials can be divided into ceramics, tungsten carbide, and hardened stainless steel, with ceramics as the costliest option and hardened stainless steel as the most affordable. Quality and durability align with cost: Ceramic materials offer the highest quality, followed by hard tungsten alloy, with hardened stainless steel as a lower-quality option. | |||

In 2010, the FDA announced a recall of eleven batches of clevidipine butyrate injection emulsion across the United States due to the possibility that the emulsion contained inert metallic particles. | In 2010, the FDA announced a recall of eleven batches of clevidipine butyrate injection emulsion across the United States due to the possibility that the emulsion contained inert metallic particles<ref>Recall -- Firm Press Release. FDA.[https://www.fda.gov/media/78662/download]</ref>. Particles gathering and forming larger particles would theoretically lead to clogging in blood capillaries, causing mechanical damage to the body or other acute or chronic inflammations. | ||
Therefore, it is not recommended to use the impact type of homogenization chamber in the pharmaceutical industry. These models are no longer suitable for mass production of pharmaceutical emulsion injection. The interaction mechanism is also more durable in ultra-high pressure machines when equipped with temperature control. With increasing demand for nanomaterials, which require higher pressure and higher performance in nano-dispersion, interaction chambers will be more widely used in nanotechnology fields, such as pharmaceuticals, semiconductors, and microelectronics. | Therefore, it is not recommended to use the impact type of homogenization chamber in the pharmaceutical industry.

With the development of the high thrust linear actuator system, high-thrust and low-speed linear motors will be applied in ultra-high pressure homogenizers in the future. As the pressure increases, temperature control will be a major technical challenge—and therefore, a temperature-controlled and ultra-high pressure-durable interaction chamber is a major avenue for future development. | With the development of the high thrust linear actuator system, high-thrust and low-speed linear motors will be applied in ultra-high pressure homogenizers in the future.
