LABTEX 9L Food Freeze Dryer Machine -55℃ Economical Harvest Freeze Dryer for Home and Laboratory with Vacuum Pump

The LABTEX 9L is a compact freeze dryer designed for home and laboratory use to remove water from foods and other materials by freezing and sublimation. Typical uses include preserving fruits, vegetables, pet food, creating long-term food storage, producing snacks, and small-scale R&D work.

The final condenser temperature of -55°C indicates how cold the condenser gets to capture water vapor as ice. Lower condenser temperatures improve sublimation efficiency and help preserve nutrients, flavor and structure by removing moisture at low temperatures.

The 9L condenser volume refers to the internal capacity of the condenser to collect ice formed during the freeze-drying cycle. It is not the usable sample chamber volume—actual batch size depends on the moisture content and type of material being dried.

A vacuum degree of <10 Pa means the system can achieve very low pressure (high vacuum), which is necessary for efficient sublimation of ice directly to vapor during freeze drying.

Yes, the machine includes a vacuum pump to evacuate air and enable sublimation. Follow the pump manual for oil type, oil-change intervals, ventilation, and operation. Ensure the pump is properly ventilated and placed on a stable surface.

Cycle time varies widely depending on sample type, thickness, water content and load size. Typical cycles range from 12 hours to several days. Start with small test batches to establish appropriate cycle parameters for your materials.

Maximum usable batch size depends on moisture content and how densely you pack samples. The 9L condenser allows moderate throughput for home/lab use, but actual sample amount should be determined experimentally—do not overpack trays to ensure even drying.

Some users pre-freeze samples to speed the process, but many freeze dryers with sufficient condenser capacity will freeze and sublimate within the same cycle. Follow the user manual and recommended procedures for best results.

You can freeze dry many liquids and purees, but they should be placed in shallow, well-spaced containers or trays to allow even freezing and sublimation. Very high-sugar, fatty or oily samples may require process adjustments. Do not attempt to freeze dry flammable, volatile or hazardous solvents.

Wear appropriate PPE for handling very cold surfaces and samples. Keep hands clear of frozen surfaces to avoid frostbite. Ensure adequate ventilation for the vacuum pump, do not freeze dry flammable/toxic materials, and follow all electrical and operating instructions in the manual.

After cycles, allow the unit to defrost, remove trays and wipe chamber and shelves with a mild detergent and clean water. Avoid immersing electrical parts. Service the vacuum pump per its manual (check oil level/change oil as recommended) and inspect seals and valves regularly.

Power specifications are not listed in this description. Voltage and power consumption may vary by region or model variant—check the product listing or contact the seller for exact voltage (e.g., 110V/220V) and wattage before plugging it in at home.

Yes, the LABTEX 9L is designed for both home and laboratory applications and can be used for R&D, pilot studies and small-scale sample preparation. For regulated, sterile or GMP workflows you may need additional validation and documentation.

Unit dimensions are approximately 582 x 541 x 374 mm. Single package size is 69 x 65 x 48 cm and the gross weight is around 80 kg. Because of its weight and fragility, check shipping arrangements and handle with appropriate equipment.

Warranty and support details are not provided in the description. Contact the seller or manufacturer (LABTEX) for information about warranty coverage, spare parts, and technical support options before purchase.
