Condenser lab

With an accout for my. In a laboratory, condenser lab 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, condenser lab, 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.

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 more. Be sure to check out our condensers with removable hose connections - they make disconnecting and reconnecting water hoses a breeze. The items below are representative of each class of condensers that we carry. To see specific sizes and configurations, simply click on a description or Choose Options link below.

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. More commonly, a condenser has a separate tube or outer chamber through which water or some other fluid is circulated, to provide a more effective cooling. Laboratory condensers are usually made of glass for chemical resistance, for ease of cleaning, and to allow visual monitoring of the operation; specifically, borosilicate glass to resist thermal shock and uneven heating by the condensing vapor. Some condensers for dedicated operations like water distillation may be made of metal. In professional laboratories, condensers usually have ground glass joints for airtight connection to the vapor source and the liquid receptacle; however, flexible tubing of an appropriate material is often used instead. The condenser may also be fused to a boiling flask as a single glassware item, as in the old retort and in devices for microscale distillation.

The heat of condensation is carried away by convection.

The condenser is an intricate piece of glassware, and allows for cold water to circulate through the distillation apparatus. The circulating water does not mix with the sample to be purified, but instead passes through another jacket surrounding the hollow tube where the gaseous sample travels. It is important that the water jacket be full of cold water, to maximize the efficiency of condensing the gaseous sample. It is for this reason that the water hoses must be attached to the condenser in a certain way. A hose should connect from the water spigot to the lower arm of the condenser, forcing water to travel against gravity through the condenser this is shown correctly in Figure 5. The hose connecting the upper arm of the condenser should then drain to the sink.

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.

It is related to the retort used by alchemists. The heat of condensation is carried away by convection. Dean—Stark Soxhlet extractor Kipp's. The Allihn condenser consists of a long glass tube with a water jacket. A raised lip around the input opening prevents the liquid from spilling through it. The vapor condenses on the inner wall of the vessel, and drips along it, collecting at the bottom of the head and then draining through a tube to a collecting vessel below. A cold finger may be a separate piece of equipment, or may be only a part of a condenser of another type. Condensers, Reflux with Coil and Jacket. The coiled condenser tubes inside will provide more surface area for cooling and for this reason it is most favorable to use but the drawback of this condenser is that as the vapors get condensed, it tends to move them up in the tube to evaporate which will also lead to the flooding of solution mixture. The Friedrichs condenser sometimes incorrectly spelled Friedrich's was invented by Fritz Walter Paul Friedrichs , who published a design for this type of condenser in

The heat of condensation is carried away by convection. A series of bulbs on the tube increases the surface area upon which the vapor constituents may condense. In the first, the spiral contains the coolant, and the condensation takes place on the outside of the spiral. Each "finger" is created by melting a small section of the wall and pushing the soft glass inwards. The ends of the outer tube are sealed usually by a blown glass ring seal , forming a water jacket, and is fitted with side ports near the ends for cooling fluid inflow and outflow. 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. The countercurrent condensers are intended to return the liquid toward the source of the vapor, as required in reflux and fractional distillation. Sign in or Create an account. Many different types of condensers have been developed for different applications and processing volumes. Category : Laboratory glassware. There also exists a version of Dimroth condenser with an external jacket, like in a Davies condenser, to further increase the cooling surface. The tube can be the inner conduit of some other type, such as Liebig or Allhin.
