Overview of equipment for freeze dryers
|
In this section, you will be guided through deciding how your freeze dryer should be configured, you will able to view our range of freeze dryers including possible options, accessories etc. as well as viewing pictures of the different parts to enable you to choose the optimal freeze dryer for your specific requirements.
|
Our range of freeze dryers
Our range covers freeze dryers with condenser temperatures from -55 ºC to -110 ºC, and they are available in different sizes from 4 liters to 80 liters capacity. Thereby, the freeze dryers are offering fast drying speeds, some of the lowest temperatures on the market, easy maintenance and comes with a wide range of chambers and accessories to suit your individual needs.
|
How do you determine the optimal size of the freeze dryer for your specific application?
When the size of the freeze dryer is to be determined several questions have to be addressed, for example:
- What condenser size (volume) is required?
- What condenser temperature is required?
- What is the maximum number of samples to be freeze dried at one time?
- What is the total volume of the samples?
- What is the size of the container/tray you want to use for the samples?
- What is the sample volume in each tube/vial?
If "bulk drying" on trays or shallow containers, the sample depth should ideally be less than 1,5 cm.
When all these questions have been answered, the size and configuration of the freeze dryer can then be determined.
|
|
What size of condenser is required?
The size of a freeze dryer is rated in size by the capacity of the condenser to hold ice that is produced in a 24 hour drying cycle (i.e. water from the sample).
As a minimum, the condenser capacity must be adequate to handle the total amount of vapor from the sample volumes in a single batch before de-icing is required.
The larger the condenser's surface area, the more efficiently vapor is condensed to ice and, consequently, the thinner the ice-layer formed.
We offer the four condenser capacities for our freeze dryers:
- 4 liters, 9 liters, 15 liters and 80 liters capacities.

|
What freeze dryer condenser temperature is needed?
The choice of condenser temperature is important!
If the temperature is too high, then a correct freeze drying process cannot take place.
In the table to the left are freezing points/collapsing temperatures of some commonly used solvents and known products. These are given for guidance purposes and to assist in deciding the condenser temperature for your application.
If the condenser temperature is near to the freezing point of the sample, then the freeze drying cycle times are extended and in risk of failure.
The product could possibly start to melt, thus giving very poor recovery rates and enhancing the possibility of damaging the vacuum pump, eventually polluting the laboratory environment. This phenomenon is known as a "collapse" of the sample.
The driving force in freeze drying is expressed as the temperature/pressure differential between the product and the condenser.
In conclusion, the lower the condenser temperature, the better! For example, for aqueous samples a -55 ºC condenser temperature is the preferred choice.
However, a lower temperature condenser will provide faster freeze drying, avoiding melting and give better results, with the additional benefit of protecting the vacuum pump and the environment.

Select the optimal freeze dryer model for your requirements
Based on your choice of temperature and volume, you can now choose the freeze dryer model suited for your requirements. Here we have 4 different models to choose between.
Basic freeze dryer model
The Basic freeze dryer model comes with digital read-out of temperature. Included are hose and flange for connections to the vacuum pump and the vacuum solenoid valve, which is controlled from the front of the freeze dryer.
Pro freeze dryer model
The Pro freeze dryer model comes with digital read-out of temperature and pressure. Included are hose and flange for connections to the vacuum pump and the vacuum solenoid valve, which is controlled from the front of the freeze dryer.
Touch freeze dryer model
The Touch freeze dryer model is for manual and automatic operation, with optimum control and regulation of temperature, pressure and time. Included are vacuum hose and flange connection to the pump.
All operations are controlled from the touchscreen display, including:
- Vacuum solenoid valve
- Pressure regulation valve for primary drying
- Vacuum release valve
- Electrical de-icing
- Software back-up
Superior Touch freeze dryer model
The superior touch freeze dryer model is for manual and automatic operation, with optimum control and regulation of temperature, pressure and time, just like the touch model. The difference between the models is that Superior Touch has the additonal facility of pre-freezing.
The Superior Touch freeze dryer models come in two versions:
- Either the 80 liters models going down to -95 ºC and -55 ºC , which can be seen in the below picture down to the right.
- Or the XS and XL models, which have capacities of 9 liters and 15 liters and have temperatures down to -100 ºC and -95 ºC. This type can be seen in the below picture down to the left.
