Product introduction

Funnel holder is an accessory used to connect the Büchner funnel and the suction filtration flask to ensure the sealing of the device, usually a sealing rubber ring. When in use, insert the Büchner funnel holder from the cylindrical outlet below the Büchner funnel, and ensure that the rubber ring and the outlet tube are tightly fitted, then insert the funnel into the upper opening of the Büchner flask, and use the sealing effect of the rubber ring to ensure the airtightness of the suction filtration device, so that negative pressure is formed during the suction filtration process, so that the liquid component is sucked into the flask under the negative pressure, and the solid remains on the filter paper.

Product features

(1) Good sealing performance: Most of them are made of rubber material, which can fit tightly between the Büchner funnel and the filter bottle to ensure the airtightness of the device during filtration.

(2) Strong adaptability: Generally designed as a universal specification, it can be applied to Büchner funnels and filter bottles of various common sizes.

(3) Convenient operation: Simple installation, just put it on the outlet of the Büchner funnel and insert it into the filter bottle, and it is also easy to disassemble.

(4) High stability: It can keep the Büchner funnel stably placed on the filter bottle to prevent the funnel from shaking or tipping over, ensuring the smooth progress of the filtration process.

Product applications

Laboratory Büchner funnel holder is mainly used in filtration experiments. It is used to connect the Büchner funnel and the filtration bottle to ensure the sealing of the device, so that a stable negative pressure can be formed during the filtration process, thereby achieving solid-liquid separation and improving filtration efficiency. At the same time, it can reduce filtrate splashing and loss, and facilitate experimental operations and subsequent processing.
