Sterility assured during freezing and defreezing operations
With a production site in the North of Italy and commercial offices in Milan and in Belgrade (Serbia), Haemopharm Healthcare has developed several innovative concepts for the pharmaceutical and medical industries.
Its product SAFE2, developed in partnership with Siad Healthcare, is a double bag that has been specially created to improve the safety of stem cell samples during cryopreservation.
Produced in ethyl vinyl acetate (EVA), this bag is suitable for long term storage in liquid nitrogen. The inside of the bag contains the samples while the outer bag protects the inner bag. The material offers high resistance and excellent flexibility.
Each bag is equipped with two ports in EVA with hermetically welded membrane to ensure the sterility during the freezing and defreezing operations. A special connector enables the connection between the EVA tube and the PVC connecting tube. The way that the connecting tube is designed to insert into the bag prevents potential damage to the bag walls.
A slit in the tube and the rounded corners of the inner bag also help to achieve complete bag drainage. The outer EVA sheet is also ribbed to make it easier to slide the inner bag inside the outer bag.
At the bottom of the bag there are two small housings for holding aliquot samples in vials or segments of tubes and for a label.
