1. High purity industrial ceramics are used for the parts in contact with materials, which have ultra-high hardness, acid and alkali corrosion resistance, high temperature resistance, low coefficient of expansion, and low to zero water absorption rate.
2. The main ceramic parts inside are precision machined using micrometer level technology, resulting in high filling accuracy.
3. Adjust the flow rate by angle for easy operation.
4. The whole machine is designed to be compact, with a 304 stainless steel appearance that is aesthetically pleasing and easy to clean.
Quantitative distribution or continuous transportation of experimental equipment, analytical equipment, and pharmaceutical equipment materials. Precision quantitative filling for industries such as acid-base corrosive liquids, biological reagents, pharmaceuticals, food, chemical cosmetics, etc.
Washing program
After cleaning with purified water, rinse thoroughly with injection water;
When stored for a long time or used for the first time, remove the heat source and soak in 1-2% NaOH for 30 minutes. Be careful not to use hot alkaline solution (temperature should not exceed 120 ° C). The sealing ring should not be soaked in alkaline solution for too long, otherwise the elasticity will deteriorate.
Sterilization Procedure
Dry heat sterilization or high-pressure moist heat steam can be used for sterilization: however, since the sealing ring can only withstand a temperature of 160 ° C, it should be removed before dry heat and sterilized with high-pressure moist heat steam. (It is recommended to use high-pressure moist heat steam for sterilization, with a sterilization temperature of 121 ° C, a pressure of 0.1MPa, and a time of 30 minutes)
Precautions for Cleaning and Sterilization
Do not use chlorine containing chemical solutions in contact with stainless steel to prevent corrosion of stainless steel parts.
Do not pull ceramic measuring components in hot water exceeding 120 ° C during cleaning. The ceramic plunger and ceramic sleeve should be cleaned separately.
During sterilization, the rotary valve, ceramic sleeve, and measuring rod should be opened separately in a dedicated sterilization box, and the ceramic rod and ceramic sleeve should be placed vertically for wet heat sterilization to prevent deformation and bending due to heat; After sterilization, the temperature of each component should naturally drop to room temperature before installation. Before the temperature of the pump body drops to room temperature, sudden cooling should be avoided to prevent damage to each component.
Due to the higher hardness of ceramics compared to metals, contact between ceramics and metals can cause the ceramic surface to become dirty, and a small amount of concentrated hydrochloric acid can be used for cleaning; If there is yellow dirt on the pump body, soak it in 10% oxalic acid for 5-10 minutes and then rinse it off with injection water.
Due to the higher hardness of ceramics compared to stainless steel, contact between ceramics and stainless steel can cause the ceramic surface to adhere to the stainless steel, which cannot be removed and may result in the filling pump not running smoothly or unable to move. Causing damage. It is recommended to use non-metallic materials as storage containers for cleaning and sterilization.
