5 Liter Cascade Benchtop Freeze Dry System from Labconco has an ice holding capacity for light to moderate sample loads and dual refrigeration systems for samples with low eutectic points
Dual refrigeration systems handle samples with very low eutectic points
, including those containing small amounts of methanol or ethanol.
However, if their eutectic points are compared, calcium nitrate is attributed to the chemical materials that are able to strongly (even up to -49[degrees]C) lower the freezing temperature of water solutions (Table 2).

The eutectic point of carbamide and water mixture is -13[degrees]C, when increasing or decreasing concentration of carbamide in the mixture with water the mixture freezing temperature raises.

5 Liter Cascade Benchtop Freeze Dry System has ice holding capacity for light to moderate sample loads and dual refrigeration systems for aqueous samples with low eutectic points
The cascade design offers a CFC/HCFC-free refrigeration system that cools the collector coils to -84 C (-119 F), which is suitable for freeze drying samples with low eutectic points
The collector cools to -84 C for processing samples with low eutectic points
Two 1/2 CFC-free and HCFC-free refrigeration systems are used in series to cool the collector to -85 C, which is suitable for samples with low eutectic points
