dryer, it also could be called as lyophilizer, so many types in market, but you just know what you want to do, which
type freeze dryer could help you make your purpose happen?
Professional selection guide of vacuum freeze dryer from TOPTION, hope could help you choice a most suitable
lyopholizer based on your actual needs.
1. The development history of vacuum freeze dryer
vacuum freeze dryer in China:
This is the earliest vacuum freeze dryer made in China, also is the first generation freeze dryer produced by TOPTION,
it has drying function, digital display cold trap temperature ( water capture device temperature) and vacuum degree,
only could reach simple drying purpose. It's also saled in market until now, and its price is lower.
As vacuum freeze dryer technolog is developing, the second generation small type vacuum freeze dryer has been
produced, compared with old type, this vacuum freeze dryer has more new advanced functions: LCD display, sample
temperature monitoring record, cold trap temperature monitoring record, has data curve display after vacuum freeze
drying, with 232 interface for convenient data output, cold trap temperature could reach -55℃ which is better for
drying speed and effection.
The main advantages of new vacuum freeze dryer is focus on circuit control aspect: LCD display, touch screen
control, research data could be output in U plate convenient, system data store capacity increase, integrated circuit
failure rate decrease, organic glass materials cover and process improvement.
2. The configuration of freeze dryer
you need to understand.
industry, chinese herbal medicine, powder material, etc.
2) Standard multi-pipe type ( TOPT-10C multi-pipe vacuum freeze dryer ): compared with standard type, this multi-
pipe vacuum lyophilizer add external bottle hanging function, connect flask at the outside of drying chamber, to dry
the material in flask, through multi-pipe switching device, you could take down or put on the flask at any time, don't
need to shut down. Besides, you could dry different materials at the same time and without cross contamination,
drying speed is rapid.
3) Top-press type ( TOPT-10B top-press vacuum freeze dryer ): most suitable for drying material in penicillin bottle,
when you prepare freeze drying, put the material in penicillin bottle based on your needs, cover the bottle cap well
then begin freeze drying, after finish freeze drying process, you could trough top-press device to press bottle cap
tight, so as to avoid secondary pollution, adsorption of water again, finally easy for long term storage.
4) Top-press multi-pipe type ( TOPT-10D top-press multi-pipe vacuum freeze dryer ): has the advantages of top-
press type and multi-pipe type at the same time.
5) Ampoule pipe type: used for ampoule pipe drying, ampoule pipe vacuum freeze dryer is mainly used for virus and
vaccine, etc. Customization welcome contact us.
6) T-type vacuum freeze dryer: applied in polypeptide.
3. How to choose small type vacuum freeze dryer
Until now, you already have know the basic selection considerations, and could choose a most suitable vacuum
freeze dryer according your actual needs.
Firstly, you need to know the characteristics of your material, choose vacuum freeze dryer configuration ( standard
type / top-press type ), then ensure the pre-freezing temperature of vacuum freeze dryer ( if you want to pre-freeze
in cryogenic refrigerator, then you could not consider this ), finally please ensure if you need to equip -80℃ function (
ordinary suitable for organic solution drying ).
4. Analysis of existing vacuum freeze dryer in market
There's three kinds vacuum freeze dryer in market now:
1) Digital display, main engine and glass cover connect with flange, cold trap -50℃, the price is lowest.
function, the price is higher than the first one.
is -55℃, new material glass cover, flushbonading connector, this type price is higher than the others.
