Lyophillizer
Freeze Dryer
A lyophiliser (freeze dryer) removes water from a frozen sample by sublimation under vacuum. It dries heat-sensitive and biological materials gently, leaving a stable, porous solid that is easy to store and redissolve.

Lyophillizer processIllustrative
01 / Overview
What is Lyophillizer?
The sample is frozen, then placed under vacuum so that its ice turns directly into vapour (sublimation). The vapour is trapped as frost on a condenser held at −50 °C or colder; gentle shelf heating supplies the energy, and a final secondary drying stage removes bound water.
Because the sample never melts or is heated strongly, proteins, cultures and plant extracts keep their activity, and the product keeps its structure as a porous cake. Oven or vacuum drying is faster but can collapse, denature or oxidise sensitive material.
02 / How it works
How it works
- 01
Sample is frozen
The sample is frozen solid in vials, tubes or trays, often at −40 °C or colder.
- 02
Vacuum is applied
The chamber is evacuated to a low pressure, typically around 0.1 mbar or lower.
- 03
Ice sublimes
Ice turns straight into vapour, which is trapped as frost on the cold condenser.
- 04
Dry product remains
Secondary drying removes bound water, leaving a dry, porous cake that is sealed and returned.
03 / What it measures
What it measures
Heat-sensitive samples
Dry at low temperature without melting or denaturing.
Useful forProteins, enzymes, cultures, plant extractsPorous cakes
Keep the original structure as a porous solid that redissolves quickly.
Useful forFormulations, scaffolds, reconstitutionSamples ready for analysis
Prepare dry material for FTIR, XRD, BET or thermal analysis.
Useful forSolid-state and surface characterisationGentle concentration
Remove water from dilute aqueous samples without heating them.

05 / Sample requirements
Sample requirements
- Accepted forms
- Aqueous solutions, suspensions, gels and wet solids
- Fill depth
- Ideally under ~1–2 cm per container; total volume by discussion
- Solvent
- Mainly water; organic solvents only in small amounts after confirmation
- Transport
- Frozen on dry ice or chilled, in sealed, labelled containers
- Freeze samples in wide, shallow containers where possible
- Mention the solvent, volume and expected dry mass
- Label each container on the side, not only the lid
- No acids, bases or high-solvent samples without discussing first
- No pathogenic or unassessed biological material
Hazardous or air-sensitive samples: mention it in your request, and attach the MSDS if you have one.
