FastWells™ Reagent Barriers

FastWells™ are sticky, flexible silicone gaskets that form hydrophobic reagent barriers around specimens without messy adhesives or special slides. Gaskets may be stacked to increase depth and volume.

FastWell™ Reagent Barriers provide rapid isolation of cells and tissues on slides or coverslips for antibody incubations. The barriers remain sealed during agitated washing steps, preventing reagents from spilling when shaken or rocked. FastWells™ peel off quickly and cleanly, leaving no residue to interfere with specimen cover-slipping. They can be washed, autoclaved and reused. The barriers can also be sealed to form incubation chambers using flexible HybriSlip™ covers.
