Rubber Ball is a device used to transfer liquids and gases.
Rubber Balls come in a wide variety of sizes and shapes to suit different applications. These include single-ball types used for both suctioning and discharging objects, those specifically designed for discharging, those equipped with multiple valves having different pressure points for exhaust and suction, and those that feed air when pressurized by a sphygmomanometer.
In addition to the most common rubber material (natural rubber), there are also various types of materials used, such as silicone, which has excellent chemical resistance, depending on the application.
An example of a gaseous rubber ball is a sphygmomanometer rubber ball, which is used to manually pump air into the arm band to pressurize it when measuring blood pressure. On the other hand, an example of a liquid object is a pipette, which is used to transfer liquid from one container to another in combination with a pipette or a komaikomi pipette.
In this case, a certain amount of solvent can also be measured out by using a pipette with a marked line or scale, such as a scalpel pipette. Safety pipettors with special three-point valves are also useful for measuring strong acids, strong alkalis, and toxic substances.
Basically, the movement of a substance by a Rubber Ball is based on the exhaust of gas inside the Rubber Ball as it is squeezed and the pressure to release the negative pressure state caused by the exhaust. When the rubber ball for the sphygmomanometer is squeezed, air inside the rubber ball is supplied to the sphygmomanometer, and when the hand is loosened, air is sucked in from the outside and the rubber ball expands to its original state.
By repeating this action, air is efficiently supplied to the arm band, and the necessary pressure for blood pressure measurement can be obtained. The Rubber Ball (single-ball type) used in combination with a pipette is set in the pipette, and when the Rubber Ball is crushed in a solution, the air inside is released and negative pressure is generated.
When the rubber ball is slowly crushed again on the container to which the liquid is to be transferred, the solvent held inside the pipette is pushed out. The Safety Pipettor uses different valves for degassing the Rubber Ball, sucking up liquid, and dispensing liquid.
The principle of aspirating solvent using the negative pressure inside the Rubber Ball is the same as that of the normal Rubber Ball, but when dispensing, the valve for dispensing is squeezed to draw air from the outside into the Rubber Ball so that the volume of the solvent cannot be held inside the pipette, and the solvent is dispensed by natural fall.
Silicone Rubber Balls are made of rubber with silicone polymer as its main component. This rubber has excellent heat resistance and can handle extreme temperature changes.
Silicone Rubber Balls are suitable for use in high-temperature environments and have high chemical resistance and durability. They are used in a wide range of applications such as medical equipment, food processing equipment, and automotive parts. Silicone Rubber Balls are also flexible and have excellent resistance to bending and stretching.
EPDM Rubber Balls are made primarily from ethylene propylene diene rubber (EPDM). This rubber has excellent weather resistance and can withstand external factors such as sunlight, rainwater, and oxygen for a long period of time.
EPDM Rubber Balls also have high chemical resistance and are highly resistant to chemicals such as acids, alkalis, and ozone. They also offer excellent heat resistance and abrasion resistance, and can be widely used in various applications where durability is required, such as outdoor environments, automotive sealing materials, construction materials, and electric wire insulation materials.
Nitrile Rubber Balls are made primarily from nitrile butadiene rubber (NBR). This rubber has excellent resistance to oil and fuel, and is used in a wide range of applications such as automotive parts, machine sealing materials, and piping, where oil resistance is required.
Nitrile rubber balls are highly weather resistant and do not deteriorate easily in outdoor environments. They are also chemical resistant and can demonstrate stable performance against many chemical substances.
Neoprene Rubber Balls are made primarily from chloroprene rubber (CR). Neoprene rubber balls have excellent weather resistance and can withstand external environmental factors such as ultraviolet rays and air pollutants. They also have high oil and chemical resistance and are stable in many oils and solvents.
Neoprene Rubber Balls have excellent abrasion and fire resistance, and are used in applications such as aircraft and automotive parts, construction materials, and protective materials for electric wires, where durability is required.
Fluoro Rubber Balls are made primarily from fluorocarbon polymer. This rubber has excellent heat resistance and is suitable for use in high-temperature environments. They also have high chemical resistance and excellent resistance to corrosive substances such as strong acids and strong alkalis.
Fluoro rubber balls have high abrasion and weather resistance, making them suitable for use in harsh environments. As a result, they are widely used in fields such as chemical processing equipment, semiconductor manufacturing, and the aerospace industry.
