▶️Overview

Parhelia Omni-Stainer™ system is a precise, cost-effective tissue stainer designed to deliver consistent results while offering substantial savings in reagents and time.

Parhelia Omni-Stainer™ system utilizes capillary action to provide smooth laminar flow of tissue staining reagents for slide mounted (Omni-Stainer S12) and coverslip mounted (Omni-Stainer C12) samples, yielding reproducible results with huge reagent and time savings.

Capillary gap liquid exchange

Parhelia Omni-Stainer™ Capillary Action 100μl of blue dye dispensed into S12 flow cell via Opentrons OT-2

With capillary gap staining, the sample rests within a staining chamber, incubating in a thin capillary layer of liquid, thus resulting in a uniform exposure of tissue to the reagents.

The liquid layer is held in place by the capillary force and won't spontaneously flow out of the chamber even if the sample is held vertically. However, the "magic" happens, when a new liquid is applied to the top edge of the staining chamber: the new liquid instantly displaces the one that is currently occupying the chamber.
