Chem-spin scraper tools provide an easy method of removing the majority of desired, dried-on solids from the interior walls of round bottom flasks. Motor driven, the spinning chain rapidly and effectively brushes the surface as the loose solids collect on the bottom. Minimal physical effort is required. Tedious, time-consuming, manual scraping with a spatula is eliminated.
Individual Rotary Scraper Tools are available to fit seven, popular, round bottom flask sizes: 100, 250 and 500mL as well as 1, 2, 3 and 5L.
Tool Kits include selections of rotary scraper tools only.
Motor Kits include everything you need to get started: rotary scraper tools, glass bushing adapters, motors and two 12V batteries.
NOTE: Chem-spin tools must only be used with the correct corresponding flask size/capacity. Caution must be used when tools are used with multiple neck flasks, chain should not enter the narrow neck area. Chains are intended for sweeping action on full radius of flask bulb.
