This Quickfit® 25ml microscale dropping funnel is designed to be used with the ML1 Quickfit® microscale Chemistry Kit (B8R05278). With a nominal 25ml capacity the dropping funnel can be utilised for addition reactions or as a separating funnel to perform liquid-liquid extractions. The PFTE stopcock has a 2mm bore which provides excellent control when reagents need to be added slowly or drop-wise to prevent side reactions. Manufactured to the same high standard as the Microscale Kit with the reassuring quality of Quickfit® ground glass joints and Pyrex borosilicate glass. Interchangeable PTFE stopcock for smooth, grease free performance. Screw thread connector system eliminates the need for lubricants and requires fewer clamps.
