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.

• Stainless steel and PTFE for rapid sample removal
• Choose from seven sizes- for 100 ml thru 5 L round bottom flasks
• Laser etched as to the size and part number
• Available individually, in tool kits and in motor kits

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 500 ml as well as 1, 2, 3 and 5 L . Tool Kits include selections of rotary scraper tools only.
