Peptide Freeze Dryers for R&D and Pilot Batch Lyophilization
Compare the LP-LGJ-30 and LP-LGJ-50 by vial format, fill volume, shelf area and total liquid load. The starting point depends on the formulation, vial loading and total liquid volume; the peptide name by itself is not enough.

- Automatic stoppering configuration
Before model selection
Start with the vial and liquid load
Two peptide projects can use the same vial but place very different demands on the shelves and condenser. These six details are enough for a practical first comparison.
- 01Vial size and closure
Outside diameter, height, stopper type and whether stoppering is required.
- 02Fill volume per vial
State the liquid fill, not only the final dry peptide weight.
- 03Vials per batch
Include the normal batch and the largest batch you expect during pilot work.
- 04Formulation details
Share the buffer or solvent system and any known temperature limits.
- 05Current cycle information
Provide shelf temperature, chamber pressure and cycle time if a method already exists.
- 06Facility conditions
Confirm power supply, room access, ventilation and available installation space.
Process window
Match the equipment to the cycle, not only the batch size
Shelf control, chamber pressure, product temperature and condenser load all matter during cycle development. A capacity figure cannot answer those questions on its own.
Primary drying
Review the intended pressure range, heat input and product-temperature monitoring method.
Buyer input: existing cycle or development targetSecondary drying
State the final moisture target or release criterion if one has already been established.

LP-LGJ-30 or LP-LGJ-50?
The larger unit adds shelf area, tray size and nominal ice capacity. For vial work, calculate the required shelf footprint and total liquid fill before using the batch-weight figure.
Smaller pilot load
LP-LGJ-30
0.3 m² shelf area- Listed batch figure
- Up to 4 kg/batch
- Tray arrangement
- 3 trays, 260 x 390 mm
- Tray spacing
- 80 mm
- Cold trap
- ≤ -75°C, no load
- Ultimate vacuum
- < 10 Pa, no load
- Listed power
- 4,000 W
- Dimensions
- 860 x 1,350 x 1,800 mm
Where it fits: the pilot vial count and total liquid load fit the smaller shelf footprint.
Larger pilot load
LP-LGJ-50
0.5 m² shelf area- Listed batch figure
- Up to 10 kg/batch
- Tray arrangement
- 3 trays, 410 x 410 mm
- Tray spacing
- 100 mm
- Cold trap
- ≤ -75°C, no load
- Ultimate vacuum
- ≤ 10 Pa, no load
- Listed power
- 5,500 W
- Dimensions
- 960 x 1,550 x 1,990 mm
Where it fits: the vial count, fill volume or pilot campaign needs the wider shelf area.

Vial stoppering review
Automatic stoppering still needs a container check
A model name cannot confirm that every vial and stopper combination will work. Send the container drawing or physical dimensions before the chamber configuration is finalized.
A
Vial dimensionsOutside diameter, total height and usable shelf footprint.
B
Stopper positionPartially inserted height before drying and final seated height.
C
Batch layoutVials per shelf, edge clearance and whether partial loads are common.
D
Closing conditionsState whether vacuum or inert-gas backfill is part of the required process.
Project boundary
Regulated production requirements need a separate review
The standard listing confirms pilot equipment specifications and automatic stoppering. It does not, by itself, establish suitability for sterile injectable production or a specific regulatory program.
Confirm before quotation if required:
- GMP documentation and qualification scope
- Cleanroom installation and chamber-cleaning strategy
- CIP, SIP or sterilization requirements
- Electronic records, audit trail or data-integrity requirements
- Solvent compatibility and site safety review
- Factory and site acceptance testing documents
Peptide freeze dryer questions
Questions to settle before choosing the machine
Is a peptide freeze dryer different from a standard lyophilizer?
The basic freeze-drying process is the same. Peptide projects often place more attention on formulation temperature limits, vial loading, pressure control, product-temperature monitoring and closing the vials after drying. The required configuration depends on the actual process.
Should I choose LP-LGJ-30 or LP-LGJ-50 by kilograms?
Not by kilograms alone. For vial-based peptide work, compare the vial diameter, fill volume, vial count, shelf footprint and total water load. The listed batch figure is a first reference, not a substitute for a loading calculation.
Does automatic stoppering mean the system is ready for sterile production?
No. Automatic stoppering is one equipment function. Sterile production can also require a defined cleanroom interface, sterilization and cleaning provisions, qualification documents, environmental controls and a validated process. Confirm those requirements separately.
What should I send for a peptide freeze dryer recommendation?
Send the vial and stopper dimensions, fill volume, vials per batch, formulation or solvent information, known temperature limits, current cycle data, required closing conditions, destination country and available power supply.
Application review
Start the model review with one real vial load
Include vial size, fill volume, vial count, formulation notes and required stoppering conditions. We will use those details to check the LP-LGJ-30 or LP-LGJ-50 starting point.
