Glass Vacuum Filter CLZZ-20

Overview

The Glass Vacuum Filter CLZZ-20 is a laboratory-scale solid–liquid separation system designed for pilot filtration processes. Built around a high-strength borosilicate glass 3.3 vessel and a stainless steel support frame, it offers a 20-liter filtration capacity in a robust, corrosion-resistant configuration. The transparent glass construction allows the entire filtration process to be observed directly, making it well suited to applications where visual monitoring of cake formation and liquid clarity is important.

Construction and Materials

The filtration vessel is manufactured from borosilicate glass 3.3, a material chosen for its strong chemical resistance and broad compatibility with a wide range of solvents and media. The vessel is supported by a stainless steel frame that provides structural stability while contributing to the unit's clean appearance and resistance to corrosion. The complete unit measures 640 mm x 640 mm x 1500 mm and weighs 3.5 kg, giving it a compact footprint for bench and pilot environments.

The temperature resistance of up to 200 °C and a maximum vacuum pressure of 0.08 MPa define the operating envelope of the system. These parameters should be observed during use to ensure safe and consistent performance across filtration runs.

Features and Serviceability

The CLZZ-20 supports various filter plate options, allowing the system to be matched to different particle sizes and process requirements. The filter plate is designed for convenient removal, which makes cleaning and routine servicing straightforward between batches.

Applications and Related Equipment

The CLZZ-20 is intended for pilot solid–liquid separation, where transparent vessels and interchangeable filter plates help operators evaluate process behavior before scaling. Laboratories that require greater throughput may consider the larger-capacity CLZZ-30 glass vacuum filter, which extends the same design approach to a higher volume.

This filter integrates naturally into workflows that begin with reaction or crystallization steps. For synthesis batches that precede filtration, a jacketed double glass reactor can prepare material that is then separated using the CLZZ-20. To keep volumes consistent across a process line, a matching 20-liter glass reactor pairs well with the 20-liter filtration capacity of this unit, helping maintain a coordinated pilot setup from reaction through separation.
