300ml Glass Solvent Filter Set Introduction

The glass solvent filter set is the main product in the current laboratory filter. Because of its simple material, low cost, convenient use, wide application and large customer base, many customers who have filtration requirements have heard of the sand core filter device. However, it is not well understood about its principle, characteristics, how to use it, and which filtering items are applicable. It is not applicable after the purchase, or it is not used correctly.

In fact, the glass solvent filter set is also a classification of laboratory vacuum filtration products, and also needs to be used together with the suction pump. The sand core mainly refers to a filter with a glass sand core in the middle of the filter bottle. The gasket is generally not used for filtering directly, but the filter film is laid on the surface of the sand chip, and the sand chip often plays a supporting role. Compared with the more traditional Buchner funnel, the effective filtration area of the sand core filtration is larger, and the fine pore diameter can make the whole filter membrane have liquid passage, while the Buchner funnel is limited to the lowering eye, so the funnel looks It seems to be relatively large, and the actual effective filtration area is extremely limited.

Hawach 300ml vacuum filter set

The above diagram of the Hawach 300ml vacuum filter set is an example. The complete glass solvent filter set includes a vacuum pumping pump, a vacuum gauge, a regulating valve, a buffer cup and a vent filter, a 300ml glass solvent filter, a sand core filter base, and aluminum. Corrosion resistant clamp 1 and 1000ml conical collection bottle, and pump tube with water blocking filter. When using, filter the filter, filter paper, filter cloth or filter on the sand filter, cover the filter bowl, fix the core base and filter bowl with the clamp, and use the connecting tube to filter the filter set and the suction pump. Connect, pour the liquid into the filter bowl and open the vacuum pump. The suction pump can cause a pressure difference between the collection bottle at the bottom of the filter bottle and the environment, and the atmospheric pressure pushes the liquid in the filter bowl through the filter. The filtered sample will flow into the collection bottle.

As a full glass material, the sand core filter bottle has better chemical resistance, no need to worry about the compatibility of the sample; since the glass is fired, no mold is needed, and the cost advantage is obvious, and the cost is high. At the same time, due to the fine pore size of the sand core, the effective filtration area has obvious advantages compared with other filtration products. In actual use, the filter membrane is more saved, the filtration speed is faster, and the plugging is not easy.
