ApplicatIons

Our long history of liquid handling is focused on high precision dosing to a variety of volumes. We have handled a wide range of products including biological materials, drugs, suspensions, solutions, and flammable and toxic chemicals.

We have integrated a wide array of technologies to dispense volume ranges from pico-liters to milliliters. We routinely integrate custom designs to facilitate cleaning between batches and quick-changeover methods to maximize machine availability.

Some application examples include:

Verification & Validation

In many applications we are required to monitor and control different product characteristics, including temperature, Ph and density. The dispense process can be monitored in-line or on-line using one of the following approaches:

Fluidics

We have vast experience in automated fluidics systems by integrating best in class components such as:

  • Fluid Storage
