RightPath Medical Diagnostics distributes, blends and fills histology solvents (reagent alcohol, graded ethanol, xylene, xylene substitutes, isopropyl alcohol, acetone and clearing agents) into bottles, gallons, pails and drums, labeled with lot number and expiration date. It is the core of our business and the fastest-moving reagent in most histology labs.

A solvent distributor and a private label filler
RightPath Medical Diagnostics is not only a private label shop.

The same fill line also serves distributors and lab networks that want those solvents under their own label.

Solvent blending & filling FAQ
Do you sell histology solvents directly to labs?
Yes. RightPath Medical Diagnostics is a distributor of histology solvents to histology and pathology laboratories, sold under the RightPath label. Private label filling is a separate option for companies that want their own brand.
What is solvent blending and filling?
Solvent blending combines solvents (and water, for graded alcohols) to a defined ratio or concentration. Filling packages the finished solvent into containers such as bottles, gallons, pails or drums, then seals and labels them with lot and expiration information.
Which solvents do you fill for histology labs?
Reagent alcohol, graded ethanol (70%, 80%, 95%, 100%), xylene, xylene substitutes, isopropyl alcohol, acetone and clearing agents are our most common fills. Other solvents and custom ratios can be quoted from your specification.
Can you make graded alcohols at a custom concentration?
Yes. Graded alcohols are blended to the concentration your processor and staining protocols call for, so every container in the series matches your SOP.
What is the difference between xylene and a xylene substitute?
Xylene is the traditional clearing agent for paraffin processing and deparaffinization. Xylene substitutes are formulated to perform the same clearing role with lower odor or different handling characteristics. Many labs run both, and we fill either.
What package sizes can you fill?
Bottles, gallons, multi-gallon cases, pails and drums, with larger bulk volumes on request. We match the package to how your lab dispenses the solvent.
How are flammable solvents shipped?
Flammable solvents are packaged and labeled for compliant ground shipment. We do not add duplicate hazardous-material charges, and orders over $500 ship free.
Can you fill solvents under our private label?
Yes. Any solvent we fill can be labeled with your brand. See our private label program.
