Commercial Vial Pilot Lyophilizer With CE Certification
Pre-freezing operation of centrifugal laboratory freeze dryer
1.A small amount of products in the laboratory freeze dryer are generally pre-frozen in the cold trap cylinder. The flask needs to be equipped with a cold bath with a freezing device to pre-freeze into a shell structure.
2.The laboratory freeze dryer with centrifugal attachment pre-freezes the product by vacuum refrigeration. The ampule with the product is placed on a rotatable support and rotated at 800-1000 rpm.
3.When the vial is pre-frozen, the half-pressed bottle should be placed on the plate with the support, and the bracket and the layer should be pre-frozen in a low-temperature refrigerator.
4.The product pre-frozen in the cold trap barrel is the same as the pre-freezing transfer method in the refrigerator.
5.When the flask is lyophilized, the bell jar with multi-manifold is placed in advance, the cold trap is cooled and the vacuum is drawn. At this time, the frozen flasks are quickly connected to the valve one by one, and the valve is rotated to evacuate the flask.
6.The ampoules pre-frozen with the centrifugal attachment do not need to be converted. After the vacuum reaches a higher value, the product is already frozen. Just turn off the motor of the centrifugal rotor, as the product is already sublimating.
