A lecturer at the University of Ilorin, Kamoldeen Ajijolakewu has reportedly designed a low-temperature refrigerator which works at -45 oC.

The refrigerator which is said to be the first of its kind in the history of the University has the capacity to freeze water or any liquid kept in it within three minutes.

According to UNILORIN Bulletin, the machine, designed by Ajijolakewu, who lectures at the Department of Microbiology in the University’s Faculty of Life Sciences is more powerful than conventional refrigerators as it works at -45 oC while the conventional ones work between the range of -10 oC and -20 oC.

Ajijolakewu plans to design a much better refrigerator

Talking about his invention, Ajijolakewu said research is ongoing on the need to further reduce the refrigerator’s effective temperature, adding that the target is to design a refrigerator that works at -79oC or -80oC.

“This locally designed low-temperature refrigerator will be very useful in laboratories, restaurants and in the business of preservation of items or organisms.

“Lyophilised industrial or medically important organisms, cell lines and plant and animal cell tissue cultures require a negative-range low temperature refrigeration system to maintain them for a longer time.

“From this system, they can be accessed and rejuvenated for subsequent use in the laboratory while maintaining all their characteristics.” the lecturer said.

The refrigerator is one of the products the University of Ilorin presented for exhibition at the on-going 7th Trade Fair, holding at the Baseball Field, Adewole area, in Kwara State.
