Condensers are a critical tool in all areas of chemistry. We also include here accessories that you will find useful such as spill alarms, water flow mointors and condenser lab. Be sure to check out our condensers with removable hose connections - they make disconnecting and reconnecting water hoses a breeze.

In chemistry , a condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. Condensers are routinely used in laboratory operations such as distillation , reflux , and extraction. In distillation, a mixture is heated until the more volatile components boil off, the vapors are condensed, and collected in a separate container. In reflux, a reaction involving volatile liquids is carried out at their boiling point, to speed it up; and the vapors that inevitably come off are condensed and returned to the reaction vessel. In Soxhlet extraction, a hot solvent is infused onto some powdered material, such as ground seeds, to leach out some poorly soluble component; the solvent is then automatically distilled out of the resulting solution, condensed, and infused again. Many different types of condensers have been developed for different applications and processing volumes. The simplest and oldest condenser is just a long tube through which the vapors are directed, with the outside air providing the cooling.

With an accout for my. In a laboratory, a condenser is a piece of laboratory glassware used to cool hot vapors or liquids. A condenser usually consists of a large glass tube containing a smaller glass tube running its entire length, within which the hot fluids pass. The ends of the inner glass tube are usually fitted with ground glass joints which are easily fitted with other glassware. The upper end is usually left open to the atmosphere, or vented through a bubbler, or a drying tube to prevent the ingress of water or oxygen. For maximum efficiency, the cold water always enters through the bottom fitting, and exits through the top fitting. Multiple condensers may be connected in series, but a high flow rate must be maintained. Condensers are often used in reflux , where the hot solvent vapors of a liquid being heated are cooled and allowed to drip back. This reduces the loss of solvent allowing the mixture to be heated for extended periods. Condensers are used in distillation to cool the hot vapors, condensing them into liquid for separate collection. For fractional distillation , an air or Vigreux condenser is usually used to slow the rate at which the hot vapors rise, giving a better separation between the different components in the distillate. For microscale distillation, there are commercially available apparatus which include the "pot", the Claisen head, and the condenser fused into one-piece. This reduces the hold-up volume, and obviates the need for ground glass joints preventing contamination by grease and air leaks. An air condenser is the simplest sort of condenser. There is only one tube, and the heat of the fluid is conducted to the glass, which is cooled by air.

In reflux, a reaction involving volatile liquids is carried out at their boiling point, to speed it up; and the vapors that inevitably come off are condensed and returned to the reaction vessel, condenser lab. Open-topped cold fingers can use a wider variety of coolants since condenser lab allow solids to be inserted, and can be used with water ice, dry ice, and liquid nitrogen.

Welcome to Science Equip! A condenser is a piece of laboratory equipment that is used to condense vapours in the lab or turn them into liquids simply by cooling them down. A lab glass condenser as the name says is typically made up of a large glass material tube with a smaller glass tube running its entire length from where the hot fluids usually pass. The upper-end part of the condenser is usually left open or vented through a bubbler or a drying tube to prevent the entrance of the water or oxygen. Coldwater is always supposed to enter through the top fitting of the condenser for attaining maximum efficiency. Glass is commonly used in the chemical laboratory condensers as the glass condensers are viable for chemical resistance, can easily clean the apparatus, and also for visually monitoring the entire operation. Few condensers which are specifically used for dedicated operations are made up of metal. There are various lab condenser types depending upon the need :. Air condenser : This type is one of the simplest forms of condenser.

Condenser laboratory In a laboratory, a condenser is a piece of laboratory glassware used to cool hot vapors or liquids. Davies" as a director of the company. The concurrent condensers receive the vapor through one port and deliver the liquid through another port, as required in simple distillation. They are usually mounted vertically, above the source of the vapor, that enters them from the bottom. A list of authors is available in Wikipedia. They are often found in rotary evaporators. This configuration maximizes flow capacity since vapors can flow over and around the spiral. Water can absorb much more heat than the same volume of air, and its constant circulation through the water jacket keeps the condenser's temperature constant. This is not to be confused with the coil condenser. Choose Options. In the second configuration, the jacket tube contains the coolant, and the condensation takes place inside the spiral. The two outer tubes 3 and 4 form an insulating dead air chamber shaded.

The condenser is an intricate piece of glassware, and allows for cold water to circulate through the distillation apparatus.

For microscale distillation, there are commercially available apparatus which include the "pot", the Claisen head, and the condenser fused into one-piece. This increases the cooling surface, so that the condenser can be shorter than an equivalent Liebig condenser. The condenser's construction is explained on pp. Other cooling fluids may be used instead of water. Journal of Chemical Education. All trademarks shown are the property of their respective owners.

The concurrent condensers receive the vapor through one port and deliver the liquid through another port, as required in simple distillation. Gallenkamp and Co. The inner-tube is straight, making it cheaper to manufacture. Poisonnier, in and the Finnish chemist Johan Gadolin in Add To Cart. Select sub-category. Though named after the German chemist Justus Baron von Liebig , he cannot be given credit for having invented it because it was already in use for some time before him.
