Flowsorb III以速度，准确性和可靠性提供单点和多点BET表面积测量。很容易容纳具有从0.01 m2 /g到1,000 m2 /g的表面积的样品。

Features and Benefits:

超稳定的检测器消除了漂移和恒定调整的需求
Cold trap conveniently located in front vs. side placement, as in other instruments. This placement reduces the chance of breakage.
Single injection calibration requires only one control setting. Adaptable to any non-corrosive adsorbate mix.
All controls and displays are at eye/ arm level, out of the spill zone
Built-in sample preparation Rugged construction for day-in, dayout operation
崎rugged的施工，用于日间运营

The FlowSorb III’s reproducibility is better than 0.5%. The FlowSorb III 2310 features a built-in Dewar elevator for completely automated analysis and rewarming fan for rapidly warming the sample tube to increase the speed of the sample analysis. Single injection calibration provides fast start-up and high sample throughput. Specially designed sample holders can be attached and removed from the instrument with one hand.

These quick connect/disconnects have a built-in isolation valve to prevent sample contamination. The FlowSorb III 2305 features a Dewar support latch system that provides one-handed convenience and safe guards against LN2 spills. Simple in design, the Flow-Sorb III requires minimal training time and leaves little chance of operator error. Automatic mode switching for adsorption and desorption is accomplished without operator attention. The low purchase price of the FlowSorb III and its accessories make this instrument one of the most inexpensive ways for a laboratory to begin measuring BET surface area.
