Shop by form.
Every reference standard arrives in one of four physical formats. Lyophilized vials are freeze-dried for shelf stability, intranasal sprays come pre-reconstituted, reconstituted liquids ship ready to use, and pre-formulated pens deliver a sealed 3 mL dose. Choose the format that suits your bench.
Lyophilized vials.
Freeze-dried for shelf stability and shipped sealed, ready for the bench. See our notes on lyophilization cycles for the reconstitution workflow.
Intranasal sprays.
Supplied pre-reconstituted in a metered nasal format, for convenience at the bench with no mixing step.
Reconstituted liquids.
Supplied in solution as a ready-to-use research liquid, with no preparation required before the work begins.
Research pens.
Supplied as a sealed 3 mL research pen, pre-formulated and ready to use, with no reconstitution required before the work begins.
