This sample tubes feature wider diameter, constricted condensation zone, thicker glass wall and can process higher volumes compared to sample tubes from other manufacturers.

• Precision joint: tightness, avoid fume leaks
• Constricted condensation zone; no splashing
• Wider diameter; reduced foaming
• Thicker glass wall, longer lifetime

The engineering and design ensures a better seal to the suction module of the digester and the splash protector of the distillation unit. All BUCHI Kjeldahl glassware (100, 300 and 500 ml) maintain the same integrity and upper opening shape. By use of built-in distillation unit design, all glassware will fit properly.
