試驗室二分器適用于試驗室對煤樣、礦樣等顆粒物料的縮分有較強的均勻性，提高縮分效率和質量，依據GB474《煤樣制備方法》生產。本產品由原地礦部唯一指定企業生產，執行行業標準。

It serves division of granular materials such as coal, ore samples in laboratory. It can improve division efficiency and quality. It is prepared according to coal sample preparing method in GB474.

CGF型二分器由分樣槽、分樣斗、接樣器、架子和簸箕組成，適用于煤、礦樣或其它不均勻粒狀物料的縮分取樣分析，每組二分器分四種不同規格，分別適用于不用粒度的樣品縮分。

CGF riffle consists of sample splitting trench, sample splitting hopper, sample receiver, frame, and dustpan. It applies to sample splitting analysis of coal, ore samples, and other materials of uneven grain sizes. There are four different specifications available for every set of riffle, which are respectively applicable to the splitting of samples of different granule sizes.

此二分器結構合理，使用方便，具有多點縮分性能，有較強的代表性，可以大大提高制樣的效率的質量。

This type of riffle is reasonably structured and easy to use. It can split samples at many points and is highly representative. With it, the efficiency of sample preparation can be greatly improved.

注：另可根據用戶要求做32個和36個格槽等各種規格的二分器，每套為大、中、小。

Note: Riffles of various specifications can be made based on user requirements. For example, riffles with 32 cells or 36 cells can be designed specially for users. Every set of riffles include large-sized, medium-sized, and small-sized ones.
