Which Freeze Dryer Chamber? For your benchtop freeze dryer...

Updated: Aug 4, 2023

As LyoDry Freeze Dryers manufacturers, we also supply a comprehensive range of freeze dryer accessories, such as chambers, trays, spin freezers and secondary drying manifolds, to name but a few. Which chamber is best for your benchtop freeze drying application?

Which Freeze Dryer Chamber?

The freeze dryer chamber and accessories that we supply for both benchtop (5Kg

condenser) and Midi (18Kg condenser) are compatible not only with LyoDry freeze dryers, but also with most Edwards and Savant EF4K Modulyo and EF12K Supermodulyo freeze dryers.

The Acrylic Chamber (part no LSDC) and 6-Tray Drying Rack (part no LSD6) with stainless steel trays enables freeze drying of multiple samples in a single cycle. LSDC directly replaces the obsolete Edwards chamber (part number F056-52-000). LSD6 tray drying rack has 6 removable trays, each of which measure 284mm diameter, providing a total drying area of 0.38m². This is our most popular freeze dryer chamber configuration for benchtop lyophilizers.

Need to freeze dry faster? Adding heat to a simple benchtop freeze dryer chamber can speed up the freeze drying process. The Heated Tray Drying Accessory (part number LSAD6H) incorporates the acrylic chamber, tray accessory, with the addition of heater mats and a temperature controller (0°C – 60°C).

If you need more flexibility, to freeze dry in flasks and bulk samples, the Acrylic Chamber with 8-port lid (part no LSDCV) can be used with the 6-tray accessory mentioned above. Each of the 8 ports is fitted with a neoprene valve, 3/4" ID, suitable for flasks of up to 1 litre capacity.

For freeze drying only in flasks, the 24-port column manifold in stainless steel is supplied complete with 24 neoprene valves, each of which are 3/4" ID, and suitable for flasks of up to 1 litre capacity.

We also supply the neoprene valves (part number LSRV) as spares, along with B19, B24 and B29 rubber adaptors, which connect the valve to the manifold. If you already have an Edwards column manifold or drum manifold and just need replacement valves, these are compatible too, directly replacing the old Edwards part number, F056-48-000.

For freeze drying in ampoules, we supply the Spin Freeze: a self-contained vacuum chamber designed to facilitate freezing and primary drying of samples in ampoules. The Spin Freeze (part no LSSP) employs evaporative cooling and centrifugation to freeze samples in a thin layer on one side of each ampule for faster drying, and it's supplied with 5 interchangeable carriers to accommodate ampoules of varying sizes and capacities.

We also supply Secondary Drying Manifolds - designed to accommodate secondary drying of samples contained in ampoules. The Secondary Drying Manifold is available with either 24, 48 or 96 ports (part number LSDM96) for desorption (secondary drying) of samples in ampoules. Spare adaptor nipples (part number LSAN) are also available in packs of 48 units, for the secondary drying manifold (also compatible with the older Edwards secondary drying manifolds).

If greater capacity is required but on a laboratory scale budget (as opposed to pilot scale models), the LyoDry Midi freeze dryer condenser (which replaces the Supermodulyo EF12K condenser) can be used with our 10-tray, stainless steel chamber (part no LSCC10). This provides up to 1.5m² drying area and is available either unheated or heated, and can also be fitted with a manifold assembly for additional flask drying. This chamber can also be retrofitted to a Supermodulyo.
