Goldmann Apparatus

Goldmann apparatus

The Goldmann apparatus is a device designed to isolate helminth eggs from various liquids. It is a glass or metal funnel with a membrane filter installed at the bottom. The funnel is connected by a ring to a flat-bottomed flask. The flask, in turn, is connected to a vacuum pump.

The operating principle of the device is based on filtering liquid through a membrane on which helminth eggs are retained. The material to be tested (feces, urine, etc.) is poured into a funnel. The vacuum pump turns on, thanks to the vacuum, the liquid is sucked through the membrane filter and enters the flask. Helminth eggs, which are larger than the pores of the filter, remain on its surface.

After filtration, the membrane is removed and viewed under a microscope to detect and count parasite eggs. The Goldman apparatus allows you to quickly and efficiently concentrate helminth eggs from liquid media for subsequent analysis.

A Goldmann apparatus is a device that is used to remove helminth (parasitic worm) eggs from body fluids such as urine, feces, or blood. This device was invented in 1874 by the German physician and scientist Ludwig Goldmann, who was the first to describe the life cycle of parasites.

The operating principle of the Goldmann apparatus is based on the use of a funnel, which is connected to a flat-bottomed flask through a ring. The liquid containing the helminth eggs is placed in a funnel, where it passes through a membrane filter that traps the parasite eggs. The liquid then enters the flask, where the helminth eggs remain on the filter.

The Goldmann apparatus is an important tool in medicine and parasitology, as it allows you to quickly and effectively isolate helminth eggs for further research and diagnosis of diseases. In addition, the Goldmann apparatus can be used to monitor the quality of water and food products for the presence of parasites.
