V-Sorb 2800P BET surface area and micropore analyzer introduction

V-Sorb 2800P BET surface area and micropore analyzer uses static volumetric adsorption principle, be designed with 2 analysis stations and 2 pretreatment stations. The pretreatment stations and analysis stations are separated, can work simultaneously and independently. All setting can be done through software interface, easy understanding operations can make all learners to fully master it within 1 days. This model mainly be used for research work like for universities and institutes, can be used for determine nanomaterials surface area, mesopore and micropore data.

V-Sorb 2800P BET surface area and micropore analyzer technical features

A: Vacuum System

1. Unique integral manifolds system, decrease connecting points apparently, reduce leak rate, improve ultimate vacuum.
2. Modularity design can configure as customer requests, also be benefit for future upgrading and maintenance.

B: Control System

1. Industry used programmable solenoid valve system, strong anti-interference ability, convenient for installation and uninstallation.
2. Separated analysis and pretreatment manifolds can prevent foreign matter to contaminate analysis manifolds during sample pretreatment.

C. Measures for Improving Accuracy

1. Imported silicon thin film capacitive pressure transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S. (full-scale).
2. 1Torr and 1000Torr dual pressure transducers, sectional measurement in pressure range can reduce errors in low vacuum, 1Torr pressure transducer is highly accurate than Pirani resistance vacuum gauge (general error is 10%-15%).
3. Unique monolithic manifolds system, decrease connecting points and reduce leak rate apparently.
4. Original stepping coolant level control system, ensure the coolant level unchanged when compares with sample cells in the whole analysis process, completely eliminate the analysis errors caused by dead volume.
