Product Introduction
The ZLGJ-18 is a high-capacity laboratory freeze-dryer featuring a custom vertical T-shaped rack designed to perfectly match the curvature of eggplant-shaped flasks, ensuring stable, upright placement. This unit accommodates two flasks each of 100ml, 150ml, 250ml, and 500ml capacities. It offers a cold trap temperature as low as -60°C (with an optional -80°C version available) and a single-batch ice-holding capacity of 6 kg, making it ideal for meeting the high-capacity freeze-drying needs of university laboratories, pharmaceutical R&D centers, biological research institutes, and quality control facilities.

Core Advantages
This equipment is commonly used in universities and research laboratories for the freeze-drying and preservation of samples—such as microbial strains, biological extracts, and colloids—contained in eggplant-shaped flasks. In the pharmaceutical R&D sector, it is utilized for small-scale freeze-drying trials of probiotics and new drug samples. It also finds extensive application in biological research institutions, as well as in R&D, testing, and quality control centers for food and health products.



Frequently Asked Questions
A: It supports 100ml, 150ml, 250ml, and 500ml sizes; each batch can simultaneously process two vials of each of two different sizes.
Q: Is a separate pre-freezing freezer required?
A: No, this upright laboratory freeze dryer features a built-in, independent pre-freezing function, allowing loading, pre-freezing, and the subsequent drying process to be completed within the same chamber.
Q: What are the advantages of the KF25 clamp?
A: It allows for quick connection and disconnection without tools and offers excellent vacuum sealing performance. Using the KF25 quick-connect interface saves installation time while ensuring a stable vacuum level.
Q: Is the T-rack easy to clean?
A: Yes, the rack is detachable and can be cleaned with water or sterilized via autoclave.
Q: Is it noisy when used in a quiet laboratory environment?
