•  High speed cooling centrifuge (Eppendorf, Germany).
•  Spectrophotometer (ABBOTA, USA).
•  Gel electrophoresis.
•  UV transilluminator.
•  Microwave.
•  Laptop.

5) Cryopreservation Unit:

­ For storage of cells and tissues in liquid nitrogen (-200).

­ Equipped with:

•  Liquid nitrogen tank: as a reservoir for liquid nitrogen.
•  2 Liquid nitrogen locators with racks (Thermo Scientific, USA): for storage of samples.
•  Controlled-rate freezer (Thermo Scientific, USA).

6)Store.

– For storing sterile disposables.
