It features an air-supported spring oscillator system that uses a transparent hose to introduce air, minimizing friction along the track for smooth movement of the transparent sliding block. A visible spring assembly reacts to applied forces. The instrument includes a horizontal scale beam with centimeter markings for measuring displacement. It is mounted on a stable blue rectangular base with black posts. Dimensions: 30 cm length, 9 cm height, 10 cm width.","image_url":null,"href":"/product/wp-dcd-10001398198.html","buy_url":"https://uecyem-u1.myshopify.com/products/wp-dcd-10001398198","buy_url_source":"shops.shop_domain + product.handle","seller_name":"uecyem-u1.myshopify.com","seller_url":"https://uecyem-u1.myshopify.com/","return_policy_url":"https://uecyem-u1.myshopify.com/policies/refund-policy","media":[],"related":[{"handle":"wp-dcd-10001398929","title":"Electric Motor Model with Box for Science Physics Teaching","category":"Physics Teaching Equipment","price":"$16.49","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/c207369e-2a51-4bc3-b029-10e72aa00d01.jpg?v=1786270043","sku":"dcd-30003969834","href":"/product/wp-dcd-10001398929.html"},{"handle":"wp-dcd-10001398199","title":"Vertical Spring Oscillator with Metal Frame for Physics Demonstrations","category":"Physics Teaching Equipment","price":"$10.00","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/d00c88b4-98ee-4e7f-b6ec-d4d001bfed25.jpg?v=1786269952","sku":"dcd-30003967934","href":"/product/wp-dcd-10001398199.html"},{"handle":"wp-dcd-10001398197","title":"Double-Spring Oscillator Bench-Style for Physics Demonstrations","category":"Physics Teaching Equipment","price":"$4.03","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/2bdcf1ae-629d-41ee-b608-a195751cce9a.jpg?v=1786269934","sku":"dcd-30003967932","href":"/product/wp-dcd-10001398197.html"},{"handle":"wp-dcd-10001398196","title":"Three-Phase Induction Motor Model for Physics Teaching","category":"Physics Teaching Equipment","price":"$25.00","image_url":"https://cdn.shopify.com/s/files/1/0807/5486/8463/files/b47d0d42-1065-433f-a4cd-6223c5125159.jpg?v=1786270518","sku":"dcd-30003967931","href":"/product/wp-dcd-10001398196.html"}]}}
