Cold traps: construction, operation and principles Cold traps are used in conjunction with vacuum pumps to collect condensation produced from humidity or solvents and these cold traps can be used for many different tasks. The most common application is collecting condensation produced from humidity or solvents from rotating discs, vacuum pumps or high vacuum systems that use‘s oil diffusion or turbo-molecular pumps. In this case a common coolant such as liquid nitrogen (LN2) or dry-ice (CO2) with acetone is normally used. Another application is the production of condensation from specific...

Vacuum connection Different versions All cold traps out of glass can be manufactured with different connections. The types of connection listed here are subject to standards or norms, so that they are guaranteed to be compatible with other products and this presents the user with a variety of connection options. As the connection option product pallet is far too extensively for a standard pallet, only cold traps with a fitted connection are shown in this catalogue, however these can be altered without incurring any additional expenditure. The most common connections used in the vacuum...

CO2 wire basket for cold traps If dry ice (CO2) is used as coolant, it might get difficult to exchange the glass cold trap. The CO2 can fill up the existing space inside the Dewar flask. It is nearly impossible to replace the trap into the Dewar flask, then. Therefore we designed a wire basket for easily placing the cold trap into the already filled Dewar flask.

Drainer for cold traps with a tub for condensate water To defrost cold traps safely, you can use a drainer. The frozen cold trap will be replaced from the Dewar flask into the drainer. The cold trap can defreeze in the rack safely. The water formed during defrosting through condensation on the outside of the cold trap can drain into the drainer and will be collected in the tub. The frame is useable for all KGW-Isotherm standard cold traps model series Type S29 and SL29 with a diameter of 50mm. Other sizes on request.

Cold Traps ( cold finger condenser ) Simple cold traps, which are also known as cold finger condensers, are used in standard applications in conjunction with vacuum pumps and the condensation is forced out of the humidity or solvents used in the chemical applications. The cold trap is used to protect the vacuum pump in this case and the speciality of this type of construction is that the user does not need to use a stand to hold the cold trap. The cold trap has a rim, which is hung inside the Dewar-flask's support ring. The cold trap can be changed very quickly without any problems arising....

Cold traps with a spout ( cold finger condenser ) An upgraded version is a cold trap with an outlet. These cold traps are constructed in the same way as standard cold traps but have a GL 32 glass thread together with a screw-on cap, which is the actual spout. With the help of this spout the condensate can easily be poured out of the cold trap. Therefore the cold trap is easily to clean. Cold trap complete with Component parts theoret. cap. = theoretical capacity

Cold traps long version ( cold finger condenser ) This cold traps are constructed in the same way as standard cold traps. The condensation area of cold traps has been extended in order to trap a more condensation. In addition to this, these complete cold traps also have a larger plastic ring and a bigger Dewar flask. Cold trap complete with Component parts theoret. cap. = theoretical capacity

Cold traps long version with spout (cold finger condenser) An upgraded version is a long version cold trap with an outlet spout. These cold traps are constructed in the same way as standard cold traps but have a GL 32 glass thread together with a screw-on cap, which is the actual spout. With the help of this spout the condensate can easily be poured out of the cold trap. Therefore the cold trap is easily to clean.

Cold traps, two sections, in standard and long versions The two section cold trap is a special design available in both, standard and long version. It has a conical ground joint NS 45/40 as connection part. The condensation area can be separated from the upper section of cold trap. Therefore it is easy to pour out the condensate and to clean the whole cold trap. This version is also perfect, if the cold trap is permanently installed in an apparatus, since the upper section can stay, while the lower section is taken off for cleaning. The connection part NS 45/40 is secured by a spring clamp...
