XUP™ · Xylene-free clearing reagent

Deparaffinize and clear without xylene

XUP™ replaces xylene in deparaffinization and clearing, so your laboratory keeps its existing process while the xylene vapor leaves the room.

GDxDORCO 35 Series · Microtome blades

A new blade, engineered from the edge up

Not a relabeled blade. The 35 Series was developed from the ground up with DORCO’s blade engineering over a 1,628-day joint program, for clean, consistent sections in low-profile 35L and high-profile 35H.

IRST · ICSP-300 · Reagent supply

Work simple.

“We are histotechnologists, not chemists.” IRST stirs and supplies solvents to your tissue processors. ICSP-300 dilutes buffers and refills your IHC stainers automatically. No one on your team decants or dilutes by hand.

Local production

Reagents made close to the laboratories that use them

Shipping solvents and fixatives across oceans adds hazardous-goods cost, long lead times and supply risk. We are building local production of our reagents with partners in key markets, transferring our formulations, quality systems and filling know-how so laboratories receive the same GD quality from a nearby source.
