A respriation chamber of low original cost was used, which because of its large size was adapted to handling samples of considerable bulk or quatity. The most important feature of the chamber was its wide mouth, which permitted easy insertion and removal of samples. With the double system of connections, either total or intermittent determinations were made with only momentary stoppage of the air-stream. The flow-meter proved very satisfactor in maintaining a known and uniform rate of aeration. The apparatus described was admirably adapted to the determination of carbon dioxide as a measure of respiration on apples, tomatoes and cut flowers.
使用了一个原始成本低的呼吸室，由于其体积大，适用于处理大量或大量的样品。该室最重要的特点是其宽大的开口，便于样品的插入和取出。通过双连接系统，可以进行完全或间歇测定，而只需短暂停止气流。流量计在保持已知和均匀的充气速率方面非常令人满意。所描述的仪器非常适合于通过测量二氧化碳来确定苹果、西红柿和切花的呼吸作用。
