Which Freeze Dryer Chamber is best for your Laboratory Freeze Dryer?

Updated: Dec 5, 2022

As LyoDry Freeze Dryers manufacturers, MechaTech Systems also supply a large range of freeze dryer accessories - chambers, trays, spin freezers etc - and spare parts which are suitable for use with LyoDry Laboratory freeze dryers. Wondering which is best for your freeze drying application? Read on...!


LyoDry 'Laboratory Freeze Dryers' includes our Benchtop range and also our Midi range. LyoDry laboratory freeze dryers were designed to directly replace the (now obsolete) Edwards Modulyo and Supermodulyo range. Therefore, our freeze dryer accessories and spares are usually compatible with these freeze dryers too (if you're unsure, we will be pleased to check this for you).


Our most popular drying chamber accessory is the Acrylic Chamber and 6-Tray Drying Rack with removable trays, which enables freeze drying of multiple samples in a single cycle. The acrylic chamber directly replaces the obsolete Edwards chamber (part number F056-52-000).



Need to add heat? Our Heated Tray Drying Accessory includes the acrylic chamber, tray accessory, heater mats and temperature controller (0°C – 60°C).


Acrylic Drying Chamber with 8-port lid for freeze drying bulk samples and in flasks

If you need more flexibility, with the ability to freeze dry in flasks as well as bulk samples, the Acrylic Chamber with 8-port lid can be coupled with the 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. We also offer this chamber with a stainless steel chamber if preferred.


24-port column manifold for freeze drying in flasks

Or if you are only freeze drying in flasks, the 24-port column manifold in stainless steel is compatible both with LyoDry Benchtop and Midi freeze dryers and also Modulyo and Supermodulyo models. It is supplied complete with 24 neoprene valves, each of which are 3/4" ID, and suitable for flasks of up to 1 litre capacity


Manifold valve

We also supply the neoprene valves individually too, 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 Spin Freezers and Secondary Drying Manifolds , either with your new LyoDry Benchtop or Midi freeze dryer, or as replacements to suit your Edwards Modulyo or Supermodulyo.

Spin Freezer

The Spin Freezer 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.



Secondary drying manifold


The Secondary Drying Manifold is available with either 24, 48 or 96 ports (part number LSDM96) for desorption (secondary drying) of samples in ampoules.

Adaptors for secondary drying manifold


We also supply spare adaptor nipples (part number LSAN) in packs of 48 units, for the secondary drying manifold (also compatible with the older Edwards secondary drying manifolds).


10-tray stainless steel freeze drying chamber

If greater capacity is required but on a laboratory scale budget (rather than the more expensive 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. 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.
