{"product_id":"electroscope-rod-assembly","title":"Electroscope Rod Assembly.","description":"Our Electroscope Rod Assembly is designed to be a replacement for our Flask Type Electroscope (#4-50160), though it can be used to create an electroscope of your own. At one end of the rod assembly there is a clip for holding electroscope foil. The stopper has a bottom diameter of 28mm and a top diameter of 32mm. This size is intended to fit a standard 250ml Erlenmeyer flask. If you want to use a different sized stopper when creating your own electroscope, the rod has 6.2mm diameter and will fit in any stopper with a hole of that size.","brand":"GSC International","offers":[{"title":"Default Title","offer_id":49507502063893,"sku":"GSC4-50160","price":4.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/4-50160.jpg?v=1761839200","url":"https:\/\/unitedsupplycorp.com\/products\/electroscope-rod-assembly","provider":"United Supply Corp.","version":"1.0","type":"link"}
