It’s vital equipment in the clinical lab and for cell therapies, as helps doctors and physicians to determine whether count blood cells are alive or dead. This device is made of microchannels that divide two chambers where particle or cells with fluid is drawn through the microchannel. 

The microchannel is made of an electrolyte solution where every particle causes a little change in the liquid’s electrical resistance. The counter is used to detect electrical resistance. 

  • Clinical Laboratory Incubator 

The main purpose of using an incubator is to perform various microbiological tests. It consists of an environmentally-controlled chamber that control humidity, temperature, and carbon dioxide level in a closed area. The incubator’s environment improves the growth of various tissue and cell cultures. 

The most common use of microbiological incubators is to help the growth and storage of cell culture or bacterial culture. It also helps maintain the organism’s culture for later use. The microbiological incubator enhances the growth rate of organisms to maintain the condition. 

Another common application is the determination of BOD and the Reproduction of microbial colonies. It also helps store the samples in the lab before processing them. 

  • Sahli Haemoglobinometer

 This medical equipment uses to estimate haemoglobin in a blood sample. It operates through haemoglobin concentration’s spectrophotometric measurement. The haemoglobinometer is portable and fairly easy to use, making it ideal for a lab with minimal space. 

The device has a pipette, stirrer, comparator, haemoglobin tube, and hydrochloric acid. During the process, the blood sample turns brown after adding the acid and the solution’s color matches the comparator’s color after adding distilled water. its final level of the solution provides the quantity of haemoglobin. The result is mentioned as the grams of haemoglobin per 100 ml of blood.

  • Clinical Centrifuge

The centrifuge is vital medical laboratory equipment that use to separate a mixture of insoluble particles, sediment-suspended solids, relative densities, blood, and immiscible liquids.

This versatile equipment is used in both clinical and research laboratories and includes a rapidly rotating container that works on the centrifugal pressure performed on the contents.

In the medical lab, the centrifuge is used to separate blood components to perform tests and treatments on individual components. Different types of the centrifuge are used in laboratories and the most common types are Clinical Benchtop Centrifuges, Refrigerated Benchtop Centrifuges, Microcentrifuges  Vacuum Centrifuges, and Benchtop Centrifuges.

  • Cryostat
