The freeze dryer uses a technical method that freeze the watery
element in advance, then sublimates its moisture content under the
vacuum state to obtains the dry goods. Goods are easier for
long-term preservation after the freeze-drying processing, and they
can be restored to the original shape and form after being watered
with the original biochemical peculiarity. For the hot sensitive
substance such as antibiotic, the vaccine, the blood product, the
enzyme hormone and other biological preparations, the freeze-drying
technology can demonstrate its advantages
DFD series Freeze dryer (Table top model)
The machine is suitable for freeze drying test of laboratory
biomedical samples and a small amount production.
This series have three types: Standard (S), Top-press (T),
1, The LCD display panel, which Chinese and English language is
optional, can display drying curve, cold trap temperature, running
time, Vacuum degree.
2, Large opening trap, no coil inside, with samples pre-freeze
3, Cascade refrigeration technology, imported compressor which is
low noise, large cooling capacity and high capability of water-
4, The pre-freeze shelf can be used as guide barrel to speed up the
5, Cold trap and operation panel are made by stainless steel,
corrosion-resistant and easy to clean.
6, Transparent bell-cap drying cabinet is visual and safe.
7, The sample shelves are stainless steel, which can be adjustable
as per the requirement.
8, Valve with Nitrogen is optional.
