Description
Slotted sieve filter (Büchner funnel), DURAN®, for filter Ø of 70 mm, 220 ml is a laboratory Büchner funnel intended for filtration with glass fibre filters under vacuum. The slotted sieve plate accepts 70 mm diameter filter media, and the 220 ml capacity supports larger analytical or preparative sample volumes. Supplied as 1 pc with a weight of 0,300 kg, the funnel pairs with common suction bottles and vacuum filtration apparatus. Produced by manufacturer DWK Life Sciences in DURAN® glass, it forms part of the Büchner funnel offering for glass fibre filter filtration within vacuum technology workflows. The slotted sieve layout aids even vacuum distribution over the filter disc during solid–liquid separation. Clear specification of filter diameter and capacity simplifies selection against standard 70 mm filter papers or glass fibre discs held in laboratory stock. Single-piece supply suits dedicated filtration benches, method development and teaching environments that need robust glass Büchner ware. This funnel addresses routine laboratory filtration where a defined 70 mm filter seat and 220 ml working volume are required.
This article belongs on Büchner & filter funnels, in Funnels.
