Obtain high purity water from distillation using Thermo Scientific™ Barnstead™ Mega-Pure™ Glass Stills, constructed of non-leaching components. These glass stills effectively remove inorganic solids, organics with boiling points higher than water, bacteria and pyrogens. Available in five production capacities, units are easily wall- or bench-mounted. Maximum purity is provided from the vertical condenser design. Gain easy access for cleaning with the quick release cover.


  • Contact with only glass, quartz and PTFE components ensures ultimate purity and eliminates cross-contamination.
  • Vertical condenser design provides maximum purity.
  • High temperature cutoff shuts down the still if the temperature is too high, preventing heating element burnout.
  • Quick-release cover provides easy cleaning access.
  • Connection to optional Automatic Connection System (ACS) assures a 24-hour automatic system.
  • Stills include feedwater solenoid valve for automatic operation.
  • Stills produce water with a resistivity of 1 to 10MΩ-cm, depending on feedwater quality.


  • Compact, easy-to-use 1L/hr. glass still
  • Available with or without a storage bottle

MP-3A, MP-6A and MP-11A:

  • For larger volume demands with storage and options (3.4 to 13L/hr.)

  • No need to wait for cooling
