旋转蒸发器通常用于除去化学反应后的溶剂。结合来自蒸发槽的温和热量,控制真空用于加速蒸馏。高效的溶剂蒸馏需要真空平衡,以实现足够的压力降低,但不会超出您的rotovap冷凝能力。

韦尔奇真空提供了广泛的真空泵和系统,适用于不同的烧瓶大小,使您能够实现75至1毫巴(56.3至0.75托)的最终真空水平,并在您的旋转蒸发器流量高达138升/分钟(4.87立方英尺/分钟)。我们的产品组合还包括各种手动和电子真空调节选项,包括数字控制器,以确保可靠的结果。

  • 内置可调真空控制蒸发率
  • 三个真空等级,满足您的需求
  • Rugged chemical duty construction to resist harsh vapors

DryFast PTFE dry vacuum pumps for rotary evaporators include essential features to ensure efficient rotary evaporation. The DRYFAST tunable vacuum adjustment allows the user to optimize the vacuum for the solvent being evaporated - see Application Note below. The tunable vacuum adjustment can also be used to stop accidental bumping/foaming.

Use tunable vacuum adjustment to increase vacuum until bubbles form in the evaporation flask – then back off slight-ly. Decrease vacuum using tunable adjustment to eliminate bumping in the evaporation flask.

Use 9 torr (12 mbar) DRYFAST models for common solvent evaporations. DryFast Ultra models offer 2 torr (2.7 mbar) ultimate vacuum to strip DMF fast along with other high boiling point and low boiling point solvents.

坚固耐用的低维护无油泵具有聚四氟乙烯头、全氟橡胶阀和氟化塑料润湿表面,使DRYFAST成为溶剂、酸性和碱性蒸汽的耐用选择。

Self Cleaning Dry Vacuum Systems™ for Rotary Evaporators

The Self-Cleaning air purge cycle at the conclusion of each run maintains consistent performance and extends service intervals. This purge feature eliminates condensates in the pump’s second stage and removes volatile substances before they can solidify. This purge resets the pump diaphragms to dry startup condition, enabling consistent solvent stripping rates run after run. Solidified substances can also be abrasive to the diaphragm, impairing performance and shortening diaphragm life.

  • Anti-bumping / foaming feature with controlled evaporation rate
  • 坚固的耐腐蚀聚四氟乙烯结构
  • Self-cleaning for long life and repeatable performance

Self-Cleaning Dry Vacuum Systems™ are complete vacuum solutions for rotary evaporation. All systems feature rugged corrosion resistant PTFE diaphragm pumps for low maintenance and long life. Optimize each solvent evaporation using handy vacuum adjustment.

所有型号也包括:

  • Digital or analog vacuum read-out
  • Inlet and outlet traps to protect the pump and exhaust line from liquids
  • Prominent emergency "bump stop" switch for bumping/foaming control
  • Automatic self-cleaning purge at shutdown
