Product Description
Grease-free stopcocks keep extraction samples clean and save time scraping lubricant out of glassware. These Squibb funnels combine the classic pear shape with a smooth-turning PTFE stopcock, making them a dependable choice for routine extractions and trace-level work alike in the lab.
