Capacity 75ml altitude 11.5 cm Earwashing balls, also called ear-sucking balls, a rubber-based, spherical surface, tube-shaped instruments used to blow out wind quickly and in large quantities, initially used to absorb ear-water after swimming.It is now generally used to blow away dust on wet objects, such as keyboards and circuit boards. In the laboratory, earwash balls are mainly used to extract liquids quantitatively from suction tubes, and earwash balls can also disperse powdery substances in closed containers. Now, earwashing balls are not just used in laboratories. they are also used in many occasions: repairmen in repair shops, who often spray earwashing balls with alcohol on metal surfaces for cleaning parts, and water-absorbing drains with earwashing balls, etc. Scope of application: computer hardware, precision circuit welding, optical equipment electronics, electrical appliances, clocks, instruments, antiques and other dust removal. Especially suitable for camera lens camera lens microscope telescope clock DVD laser head dust removal.The laboratory is mainly used for quantitative liquid extraction by suction pipe. Product characteristics: Blowing balloons use latex material, anti-aging and non-degumming, full elasticity, touch hands do not stick and do not fade, winter will not harden; Enough air to allow more dust to be hidden; The neck of the blowing balloon (the air mouth and the ball body are combined) is treated thickly and is not easy to bend; Use techniques: When using blowing balloons, be careful not to blow gray to areas that cannot be cleaned.In principle, when blowing ash, the lens should be down and avoid the gray from entering the camera lens to the maximum extent possible.And when squeezing the sphere, it takes speed to produce enough air flow.Since dust usually sticks horizontally to the surface of the lens, it is easier to blow dust away from the side.
