Distillation systems

Destamat - Bi-Distillation Apparatus Bi 18E made of Quartz Glass

  In the Bi 18 E components coming into contact witti water are quartz glass parts which, contrary to ordinary laboratory glass is non-hygroscopic and thus resistant to H20. These properties warrant the high purity requirements a distillate must fulfill.

  Due to a solenoid valve, it is assured that only so much feed water (as a rule expensive VE water) is metered in, as is subsequently distilled off what finally results in a considerable cost reduction.

  The optimization of the cooling water volume is controlled by a cooling water flowmeter. The Bi18E offers the possibility of connecting an additional filling level sensor control which enables the control of the distillation volume in the collection vessel. When the vessel is full, the sensor will signal the unit to shut off or, alternatively, when the filling level falls below a preset level in the collection vessel, the apparatus switches on again automatically.

  In the event of a cooling or feed water shortage, the power supplying part is automatically shut off, thus ensunng an optimum operating safety.

  Plug and screw connections facilitate an easy cleaning and maintenance, and thus assembly and dismantling of the quartz glass components can be easily and quickly done.

  The modular structure makes it possible to increase the distillation capacity easily. The water supply is provided by simply connecting the devices via special couplings.

Acidest - Acid-Distillation Unit made of Quartz Glass for discontinuous using

  The principle of surface evaporation is especially suitable for the purification of liquids by distillation. Unlike boiling evaporation no fog or aerosol is produced. Ttie distillate is therefore of very high purity. For an analytic decomposition substances are needed which have no numerical result in a blank test. In this case It Is of advantage to distill the required acid fresh. Only thereby can any contamination by storage be avoided. During the construction phase of the ACIDEST the experience of well-known trace analytical specialists was taken into consideration. All contact of liquid and sockets Is avoided. The sockets of filling tube and collecting bottle are arranged in a way that drains ImpLirltles to the outer wall. The apparatus is filled by a specially formed funnel. After having started the operation this funnel is rotated by 90°. So the U- shaped outlet Is fifled with liquid and acts like a syphon between apparatus and outer atmosphere. Pressure balance takes place through this syphon during the heating and cooling period.

  Electric heating is done by two infrared elements of each 400 Watt at a voltage of 220 V. The full power is necessary for the distillation of sulfuric acid, whereas water, hydrochloric acid and nitric acid can be distilled with only 200- 500 Watt. In this case the ACIDEST Is used best In connedion with an usual In the trade electronic power regulator.


After filling the apparatus with 700 ml of liquid the following distillation yields are obtained approximately in the state of equilibrium (heating period is not considered):

Distillation yields (g/min):

Watt H2O HNO3 HCI H2SO4
200 1.1 1.2 0.8  
400 2.8 3.3 2.9  
600 4.4 5.3 4.9 0.3
800 5.8 7.5 7.1 0.8

The exceptional high punty of the liquids distilled only once in the ACIDEST was tested in well-known trace analytical laboratories. As a starting matenal demineralized water and common pa.-acids with metal contents of up to 100 ng./ml and more were used.

These values can only be obtained when the ACIDEST and all other used glassware was cleaned thoroughly by steaming out with concentrated nitric acid for several hours and when all analytical work is done with the required care for work with purest matenals.


 

Pyrodest - High purity Water-Distillation made of Quartz Glass for discontinuous using

  The principle of surface evaporation is especially suitable for the purification of liquids by distillation. Unlike boiling evaporation no fog or aerosol is produced. The distillate is therefore of very high purity.

  The purest water is needed for seeding the cell, tissue and organic cultures. There is no contact of water with the sockets. The sockets at the filling tube and the collecting bottle are arranged in a way that drains impurities to the outer wall. The apparatus is filled by a specially formed funnel. After having started the operation this funnel is rotated on the filling tube by 90°, so the U-shaped outlet is filled with liquid and acts like a siphon between apparatus and outer atmosphere. Pressure balance takes place through this siphon dunng the heating and cooling period.

Pyrodest - High purity Water-Distillation made of Quartz Glass for discontinuous using


Operation:

   The water surface gets  heated and   evaporated   by   infrared elements.    The    water    steam enters the  unit made of quartz glass and gets overheated (450-500°C) on its way to ttne cooling system. The overheated water steam condenses in the cooler and cumulated via outlet connecting piece in a collecting bottle. This happens without connection of water and the joints, other vise, we have a danger of impurity. For this operation a distillated or salt free liquid is necessary.

Features:

     • totally sterile distillate
     • pyrogene free
     • very low electric capability
     • lack of high molecular organic connection i. e. bacteria, pesticides, insecticides or detergencies
     • heavy metal free
     • distillate exceeds clearly the DAB7 regulations
     •
the heating system has a double function - as a surface evaporator and an overheating device
     • small size of an apparatus
     • saving energy

   Such high level of purity is needed mainly in the medicine, biology, chemistry and physics.
