Overview
The Copley Instruments 1761 Erweka TPK is a legacy critical flow control instrument engineered for pharmaceutical testing of inhalation delivery devices. Designed to meet pharmacopeial standards for aerodynamic particle size distribution (APSD) testing, the TPK series provides precise, reproducible airflow management essential for DPI (dry powder inhaler) and MDI (metered dose inhaler) validation. This used unit is suitable for laboratories maintaining established testing protocols with legacy equipment.
