Unit Operation: Blending

The ePAT 601 Blend Uniformity Monitoring system is a real time, NIR based, IP65 compliant PAT analyzer developed specifically for the pharmaceutical industry.
The system incorporates a fiber optic coupled measuring head to allow implementation onto a wide range of blenders from most blender manufacturers.

The embedded computer communicates with a remote base station computer, so that measurements can be viewed and recorded in real time. All data is recorded locally within the embedded computer such that no data is lost in the event of a wireless communication failure.

The system also comes with hot swappable batteries, which means the instrument need never be switched off or removed from the blender.

The measuring head is configured for convenient, non-contact analysis with a nominal 10mm, 20mm, or 40mm measurement area and a standard focal distance of 18mm.

The instrument is capable of measuring samples through a window, typically inserted into the lid of a blender bin and triggered by the blender's rotation.

A flush mounted window can be implemented by Expo Technologies.

The ePAT 601 can be directly installed onto existing blending equipment with minimal modification.  It is easy to calibrate, install, and operate.

Complete turn-over documentation is offered to assist with your validation.

Hot Swappable Batteries

Batteries and mains charging system are supplied. Two batteries can be charging on the mains charger while the other two batteries are utilized on the ePAT601. Both the batteries and the battery charger have inbuilt charge indicator levels.

Having two batteries attached to the ePAT601 allows power to be hot swapped.
