ZLGJ-10FTR

Product Introduction

The ZLGJ-12ST stoppering-type laboratory freeze-dryer integrates in-situ vial stoppering capabilities with freeze-drying functions for experimental materials such as small-dose biological agents or innovative drugs. Featuring stable performance and ease of operation, it is an ideal in-situ stoppering freeze-dryer for universities, pharmaceutical R&D laboratories, biological research institutions, and quality control centers.

Core Advantages

This integrated vacuum-sealed freeze dryer supports in-situ stoppering immediately after the freeze-drying process, eliminating the need for a secondary sealing step; this not only effectively prevents moisture absorption and contamination but also extends the shelf life of the freeze-dried product. Equipped with a high-precision fine-tuning vacuum valve and a vacuum alarm function, the unit enables precise vacuum control, achieving a standard vacuum level of ≤5 Pa (no-load) and an ultimate vacuum of 0.1 Pa. Its proprietary airflow technology ensures temperature uniformity within the cold trap and delivers superior water-trapping performance, creating a stable environment for the sample drying and sublimation processes.

Frequently Asked Questions

Q: How does the in-situ stoppering function work?
A: After the freeze-drying cycle, simply turn the top operating handle to simultaneously press down on all vials and seal them within the chamber. There is no need to transfer the samples.
Q: What is the processing capacity of this laboratory freeze-dryer with stoppering capabilities?
A: It can process 560 (Φ12mm), 318 (Φ16mm), or 165 (Φ22mm) vials per batch.
Q: Is separate freezing equipment required for the pre-freezing process?
A: No. This benchtop stoppering freeze-dryer features a built-in, independent pre-freezing function; loading, pre-freezing, drying, and stoppering can all be performed within the same chamber.
Q: What are the advantages of the KF25 port?
A: It supports tool-free, quick connection and disconnection while offering excellent vacuum sealing performance. This not only saves installation time but also ensures consistent vacuum levels across batches.
Q: Is the machine noisy during operation?
A: No; the noise level is ≤55dB (quieter than most laboratory refrigerators), making it ideal for use in open laboratory environments.
