Laboratory freeze dryers are commonly used in scientific research, sample preparation, and freeze-drying process development. When selecting a freeze dryer, users should consider sample characteristics, batch size, freeze-drying area, cold trap temperature, ice condenser capacity, vacuum performance, and installation requirements.

Shanghai Yetuo Technology Co., Ltd. (YETUO) offers a range of laboratory freeze dryers. The YTLG-10AN-60 and YTLG-10A are two desktop freeze dryer models sold in parallel. Both are available with an optional -80°C cold trap configuration, while their standard configurations differ in condenser capacity, equipment weight, and overall dimensions.

This guide compares the standard specifications of these two models and explains the key factors to consider when selecting laboratory freeze-drying equipment.

1. Key Factors When Selecting a Laboratory Freeze Dryer

1.1 Freeze-Drying Area

Freeze-drying area is an important specification indicating the available shelf space for sample placement, generally expressed in square meters (m²).

Both the YTLG-10AN-60 and YTLG-10A standard models offer a freeze-drying area of 0.12 m², with four material trays and a tray spacing of 70 mm.

The actual processing capacity also depends on sample quantity, layer thickness, and loading method. An identical freeze-drying area does not necessarily mean identical performance.

1.2 Cold Trap Temperature

The cold trap is designed to collect water vapor during the freeze-drying process. Its operating temperature is a key selection factor.

• YTLG-10AN-60: -60°C under no-load conditions, at an ambient temperature of 28°C or below.

• YTLG-10A: ≤-60°C for the standard configuration.

• Both models support an optional -80°C cold trap configuration.

The appropriate cold trap temperature depends on sample properties, solvent composition, and process requirements. Compatibility with special solvents should be confirmed before purchase.

1.3 Ice Condenser Capacity

Ice condenser capacity indicates the amount of water vapor that the equipment can capture under specified conditions.

• YTLG-10AN-60 standard model: 3 kg per batch.

• YTLG-10A standard model: 4 kg per batch.

Condenser capacity should not be confused with the total sample loading weight. Actual processing capacity depends on sample moisture content, loading thickness, and the freeze-drying process.

1.4 Vacuum Performance

Vacuum performance is an essential factor in freeze dryer selection. Based on the provided standard-model specifications, both models have a specified vacuum pressure of ≤5 Pa and an ultimate vacuum pressure of 2 Pa.

These two measurements refer to different performance indicators. Actual operating vacuum pressure is also influenced by pump configuration, system sealing, and sample conditions.

1.5 Dimensions and Installation

Laboratories should also consider equipment dimensions, weight, ventilation, working space, and bench load capacity. Sufficient space must be reserved for the vacuum pump, drying chamber, connecting hoses, and heat dissipation.

2. YTLG-10AN-60 vs. YTLG-10A: Technical Specifications

Note: The specifications above refer to the standard models. The YTLG-10AN-60 dimensions exclude the drying chamber cover. For optional -80°C configurations, condenser capacity, power consumption, weight, and other specifications should be confirmed against the corresponding technical documentation.

3. YETUO YTLG-10AN-60 Desktop Freeze Dryer

The YTLG-10AN-60 is a new desktop freeze dryer designed for laboratory sample freeze-drying and research applications.

Its standard configuration provides a 0.12 m² freeze-drying area, a -60°C cold trap temperature under specified no-load conditions, a condenser capacity of 3 kg per batch, and an ultimate vacuum pressure of 2 Pa.

Key Features:

• Compact desktop main unit.

• Four material trays for sample loading.

• Vacuum alarm and maintenance reminder functions.

• Support for different loading accessories, subject to configuration.

• Optional -80°C cold trap configuration.

This model is worth considering when main unit weight, available installation space, and routine laboratory sample processing are important selection factors.

4. YETUO YTLG-10A Desktop Freeze Dryer

The YTLG-10A is a desktop freeze dryer for laboratory sample preparation and freeze-drying process studies.

The standard configuration offers a 0.12 m² freeze-drying area, a cold trap temperature of ≤-60°C, a condenser capacity of 4 kg per batch, and an ultimate vacuum pressure of 2 Pa.

Key Features:

• Standard condenser capacity of 4 kg per batch.

• Four material trays with 70 mm spacing.

• Vacuum alarm and vacuum adjustment functions.

• Optional loading accessories and vacuum system configurations.

• Optional -80°C cold trap configuration.

The YTLG-10A may be considered when higher condenser capacity under the specified standard configuration is an important requirement.

5. How to Choose Between the Two Models

5.1 Equipment Weight and Space

The standard YTLG-10AN-60 main unit weighs 47.5 kg, while the YTLG-10A weighs 70 kg. Laboratories with limited installation space or bench load capacity should compare the complete equipment dimensions and installation requirements.

5.2 Condenser Capacity

The standard YTLG-10A provides a condenser capacity of 4 kg per batch, compared with 3 kg per batch for the YTLG-10AN-60. Selection should take actual sample moisture content, batch size, and process requirements into account.

5.3 Optional -80°C Configuration

Both models support an optional -80°C cold trap. Specifications for the optional configuration should be confirmed separately, rather than assuming that all standard-model specifications remain unchanged.

5.4 Sample Loading Requirements

Different samples may require trays, vials, or other freeze-drying accessories. Container dimensions, sample quantity, and process conditions should be confirmed before selecting the loading configuration.

Selection Recommendation: These two models are sold in parallel and should not be regarded as a simple replacement or upgrade relationship. Choose according to actual laboratory requirements and confirmed specifications.

6. Frequently Asked Questions

Q1: Which is better, the YTLG-10AN-60 or the YTLG-10A?

Neither model is universally better. The YTLG-10AN-60 has a lighter standard main unit, while the YTLG-10A offers higher standard condenser capacity. The appropriate choice depends on the application.

Q2: Do both models support a -80°C cold trap?

Yes. Both models are available with an optional -80°C cold trap. The specifications of the selected configuration should be confirmed before purchase.

Q3: Do both freeze dryers have the same freeze-drying area?

Yes. Both standard models provide a freeze-drying area of 0.12 m², although their condenser capacity, unit weight, and other characteristics differ.

Q4: Is a larger condenser capacity always better?

Not necessarily. Condenser capacity should match sample moisture content and batch processing requirements. It should not be used as the only selection criterion.

Q5: What information is required for freeze dryer selection?

Useful information includes sample type, batch size, moisture content, loading method, cold trap temperature requirements, and laboratory installation conditions.

Q6: How can I request a quotation for a YETUO freeze dryer?
