Reservoirs

Part of Hardware

Create flow or collect samples.

Introduction

Use reservoirs to create a liquid column for gravity-driven flow or to collect your finished sample with a pipette.

250 Microliter Reservoir

Safe Area

Reservoirs must have a safe area with a radius of 4.50 mm. The safe area of any two pieces of hardware must never overlap.

Vias

A via connects to the center of every reservoir. The diameter (D) of the via’s machined portion must be between 0.4 mm and 1 mm.

Reservoir to Feature Distance

The distance between the top surface of molded microfeatures and the base of a reservoir must be at least 1.00 mm.
