Büchner funnel smoother 50 x 135 mm with a plate height of 10 mm is a laboratory glassware accessory produced from borosilicate glass 3.3. Intended for nutsche and Büchner filtration systems, it facilitates the even smoothing of filter cakes under vacuum, promoting consistent cake thickness and efficient solvent removal in chemical and pharmaceutical laboratories. The 50 x 135 mm format offers a balanced working area suitable for medium-sized funnels used in routine sample processing and scale-up filtration tasks. Constructed from durable Boro 3.3, the smoother exhibits good resistance to common laboratory reagents and moderate temperature changes. It is supplied as one piece weighing 0,082 kg net, making it a compact addition to standard filtration setups. Available from manufacturer Witeg, this tool assists in achieving uniform solid beds that enhance washing efficiency and reduce channelling during filtration. Suitable for organic chemistry, natural-product isolation and analytical sample preparation where reliable cake handling improves overall process reproducibility.
