Medical titanium bar how to clean the filter

According to the different nature of pharmaceutical production requirements solvents and media technology engineering company for titanium filter regeneration procedures are as follows:
1, Medical titanium bar caustic:medical grade titanium  3-5% solution of sodium hydroxide AR soak for 30-60 minutes, the temperature around 40 degrees. Best in ultrasonic cleaning machine. After soaking with deionized water or filtered water for injection and outside the red to neutral, measured conductivity. Dry with clean air ≥0.4Mpa pressure.
2, Medical titanium bar acid: 5% nitric acid solution soak for 8 hours at a temperature of 40 degrees.medical titanium alloy Best in ultrasonic cleaning machine. After soaking with deionized water or filtered water for injection and outside the red to neutral, measured conductivity. Dry with clean air ≥0.4Mpa pressure.
