Product Introduction

Ningbo Scientz Freeze Drying Equipment Co., Ltd. is one of the most experienced manufacturers and suppliers of bell jar vacuum dryer in China. Please rest assured to wholesale high quality bell jar vacuum dryer made in China here from our factory. We also accept customized orders.

 

Key Features

 

Transparent bell chamber:

The drying chamber is formed as a clear bell-jar, making the entire process visible-characteristic of a true Bell jar vacuum dryer.

Touchscreen control & data recording:

7-inch color display, bilingual interface (Chinese/English), curve plotting and historical data storage suited for a modern Bell jar vacuum dryer.

Efficient refrigeration & cooling:

Imported compressor system, dual-cascade refrigeration in some versions, enable the cold trap to reach low temperatures required by a Bell jar vacuum dryer.

Strong vacuum & water capture:

Vacuum degree < 10 Pa, water capture capacity ~6 kg, essential for a Bell jar vacuum dryer to handle moderate moisture loads.

Flexible sample holders & bell adaptivity:

Standard sample trays or tubing configurations, adjustable spacing, and optional manifold compatibility-versatile use within a Bell jar vacuum dryer.

Compact footprint & ease of operation:

Small form factor, clear bell, user interface, and simple maintenance make the Bell jar vacuum dryer accessible to many labs.
