Description: The USSR VR-20 equal-arm manual balance scales (up to 20g capacity) are precision instruments designed for measuring the mass of powdered pharmaceutical substances and their mixtures, as well as other loose materials. Primarily used in pharmacies, analytical control laboratories, and other laboratory settings, these scales feature a durable brass body with nickel plating and plastic weighing pans. The core component is an equal-arm beam with two load-receiving prisms and one central support prism. The load-receiving prisms are symmetrically positioned relative to the support prism and secured to the bent ends of the beam. A pointer is soldered to the center of the beam above the support prism, indicating accurate measurements. These vintage USSR scales represent a robust and reliable solution for precise weighing in various applications.
