20L Roto - BVV

Rotary evaporator's are used in laboratories to gently remove and recover solvents from a given mixture via evaporation. Rotary evaporation is done by heating a mixture while lowering the atmospheric pressure using a vacuum system. This lowers the boiling point of the solvent forcing a phase change from liquid to vapor. The vapor is then pulled into the path of the condenser by the vacuum .

Development and Evolution of Rotary Evaporator - Lab .

The so-called "alembic" was normally made from copper but also from ceramic or glass. This principle in a modernized style is still used today in the rotary evaporators . In the 17th and 18th century the apparatuses were continually improved with regard to their distillation power.

Heat Transfer in Refrigerator Condensers and Evaporators

For the case of an evaporator or a condenser there are three components of heat transfer resistance between the air and the refrigerant. The important components are the convective resistance of the air, the conductive resistance of the heat exchanger, and the convective resistance of the refrigerant. .

Alembic - Wikipedia

Dioscorides's ambix (described in his De materia medica) is a helmet-shaped lid for gathering condensed mercury.For Athenaeus (≈225 C.E.) it is a bottle or flask. For later chemists it denotes various parts of crude distillation devices. Alembic drawings appear in works of Cleopatra the Alchemist, Synesius, and Zosimos of Panopolis.There were alembics with two (dibikos) and three (tribikos .

How to Install a Ductless Air Conditioner | The Family .

Carefully uncoil the line set from the back of the evaporator. With an assistant outside, feed the line set through the hole. As it emerges, the assistant should gently bend the line set downward and to the side as needed to reach the condenser. Keep the rigid plastic collar surrounding the line set at the end that connects to the condenser.

Sight Glass/Moisture Indicator: Refrigeration sight glass .

Sight glass-window that allows the mechanic to see inside the system. This allows the installer or Servicer to observe the state of the refrigerant in the sight glass in place. When moisture, pointing to the CD will include as shown here, it becomes moisture, pointing to the sight glass.

Alembic Pot Still with T500 Boiler (110 Volt)

This Alembic Pot Still is made up of the T500 Boiler with a Pot Still Alembic Dome Top and Pot Still Alembic Condenser. These additions transform the T500 into an Alembic Pot Still. Instead of stripping flavors to give clean spirit like the T500, this pot still retains and enhances flavors.

Laboratory Glass Condensers

The Liebig style condenser, like S-1366 has a straight tube within the water jacket that allows the vapors to move rapidly through the cooling area. The Graham Condenser such as S-1382 and S-1384 has coils on the inside of the jacket and the coolant may pass through the coils or around the coils depending on the style of the condenser.

The Glassware Gallery: Rotary Evaporators

are used to remove solvents from reaction mixtures and can accommodate volumes as large as 3 liters. They are found in almost every organic laboratory.. A typical rotary evaporator has a heatable water bath to keep the solvent from cooling or even freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal.

The "Liebig" Condenser - Yale University

The "Liebig" Condenser (note the red lessons and questions). In discussing early 19th Century contributions that still provide valuable lessons for chemistry, we have concentrated mostly on elemental analysis (for example, Combustion and Liebig's "Kaliapparat") and the theories that sprang from it.Techniques for separation and purification have always been equally important.

Analyzing Refrigerant Flow Problems

Jan 08, 2004 · Condensers are usually a bit larger than the evaporator in order to handle not only the evaporator load, but also the suction line superheat gain, heat of compression, and motor heat loads of the compressor. Like the evaporator, the surface area of the condenser also affects the design temperature difference between the condensing temperature .

Short-path distillation - Wikipedia

Short-path distillation is a distillation technique that involves the distillate travelling a short distance, often only a few centimeters, and is normally done at reduced pressure. A classic example would be a distillation involving the distillate travelling from one glass bulb to another, without the need for a condenser separating the two chambers.
