High-pass synthesizer

The utility model provides a high-pass synthesizer, which comprises a liquid discharge concave platform and a bottomless pipe support heating frame group constructed above the liquid discharge concave platform, and a sealing plate group in the liquid discharge concave platform can reciprocate along the height direction of the liquid discharge concave platform after being driven so as to be propped against or separated from the bottom of a bottomless pipe; liquid storage or liquid drainage of the bottomless pipes is achieved, the space between the adjacent bottomless pipes cannot be occupied, multiple sets of bottomless pipes which are arranged in order and connected in a sealed mode can be arranged on the bottomless pipe supporting heating frame set, and at least 96 sets of bottomless pipes can be designed. 本实用新型提供一种高通合成仪，包括排液凹台及构造在排液凹台上方的无底管支撑加热架组，所述排液凹台内的密封板组受驱动后可沿排液凹台的高度方向往复移动，进而与无底管的底部相抵或分离；实现无底管的储液或排液，不会占用相邻无底管之间的空间，可以在无底管支撑加热架组上设置多组排列整齐且密接的无底管，至少可设计九十六组无底管。
