II. Condensing device

The effect of the condenser tube directly affects the recovery rate of distilled high-concentration samples, and a high-quality condenser tube can ensure that a sufficient amount of steam can be condensed to a sufficiently low temperature to ensure that the high-concentration sample does not leak, and the recovery rate of Kjeldahl apparatus is guaranteed.
