Laboratory freeze dryer from China

A laboratory freeze dryer is chosen by what it must hold and what it must trap: the vial format and stoppering you need, and the solvent your condenser must freeze, and quotes rarely state either.

What hides inside the price

Standard, top-press or manifold

A standard chamber holds trays or open vials. A top-press model stoppers vials under vacuum at the end of the cycle, and the press takes shelf space. A manifold dries flasks hung outside the chamber.

Condenser temperature and solvent

A condenser around minus 55 °C suits water. Samples with organic solvents often need minus 80 °C. Name your solvent system before accepting the cheaper trap.

Ice capacity and sample load

Ask ice captured per 24 hours and the maximum liquid load per run. A small trap stops the cycle long before the shelves are full.

Shelf heating and probes

Some benchtop units have unheated shelves and dry slowly on ambient heat. Ask whether shelves are heated and controlled, and how many product probes are fitted.

Vacuum measurement and logging

Ask pump make and type, the gauge type, and whether shelf, condenser and pressure data export as a file.

Decode the model code.

In one Chinese series the number gives shelf area in hundredths of a square metre, and a suffix gives the chamber type. Other makers number by ice capacity, so read the table behind every code.

FD-12 standard: 0.12 m2 of shelf. FD-12 top-press: 0.08 m2.
0.12 - 0.08 = 0.04 m2 given up to the press, and 0.04 / 0.12 = one third of the shelf.

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

Sample format: vials with size and count, trays, or flasks, and the fill volume.
Solvent system, including any organic solvent, which sets condenser temperature.
Whether vials must be stoppered under vacuum or inert gas.
Liquid volume per run and runs per week.
Whether the buyer works under EU GMP and needs qualification documents.

Turn the claim into a demonstration.

Require this	A pass looks like
Empty pull-down from ambient to working condenser temperature and vacuum.	Condenser temperature and chamber pressure reached within the time written into the offer.
A full run with your formulation in your vials, followed by stoppering if quoted.	Intact cakes, residual moisture at or below target by Karl Fischer, and every vial stoppered.
Export the log of that run.	One file with shelf, product, condenser temperature and pressure for the whole cycle.

The documents that must arrive with it.

EU Declaration of Conformity for the serial number: 2006/42/EC until 19 January 2027, then Regulation (EU) 2023/1230, plus 2014/35/EU and 2014/30/EU.
Refrigerant type and charge, which F-gas Regulation (EU) 2024/573 makes your service contractor ask for.
Calibration certificates for temperature and pressure sensors, and IQ and OQ documents where the buyer qualifies under EU GMP.

The one people forget. Sensor calibration certificates. Without them the first audit treats every logged cycle as unverified.

When this is the wrong machine.

Buy something else if

Named, not hedged

You dry kilograms of food or botanicals rather than vials and flasks.

A commercial freeze dryer with larger shelf area and a food-contact file.

Your liquid feed tolerates a short burst of hot air and you need powder, not a cake.

A laboratory spray dryer, which turns liquid into powder in seconds.

Where the numbers come from.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.

Listings · 13Thirteen priced marketplace listings for Chinese laboratory freeze dryers, checked September 2026, ran from US$1,000 for benchtop units to US$67,200 for pilot machines. Asking prices, not landed cost.
Listings · 2Two spec tables from one maker's series, checked September 2026: the 12 model gives 0.12 m2 standard or 0.08 m2 top-press, condenser below minus 55 °C with minus 80 °C optional, 4 kg of ice per 24 hours and a 1.2 L sample load; the 18 model gives 6 kg per 24 hours.

Straight answers

Questions buyers ask about this machine.

Chinese vs European laboratory freeze dryer: what really differs?+

Refrigeration makes, condenser temperature, shelf heating control, gauge type, logging and service. Compare units with the same shelf area, trap temperature and chamber type.

What goes on a laboratory freeze dryer inspection checklist?+

Serial number against the declaration, shelf area, condenser pull-down, ultimate vacuum, stoppering if quoted, sensor calibration, refrigerant label and a logged run of your samples.

What CE documentation does a laboratory freeze dryer need?+

A Declaration of Conformity for that serial number with a technical file behind it, under machinery, low voltage and EMC rules. A CE mark on a listing proves nothing.

Who is the EU importer of a laboratory freeze dryer?+

Whoever places it on the EU market, usually the lab or company buying direct. Your name goes on the unit or papers and you check the conformity file.
