Cubitainer Bulk Liquid Containers

A cubitainer is the workhorse of the bulk-liquid lab and clinical setting: a collapsible poly bladder inside a rigid corrugated box that dispenses cleanly, ships stable, and collapses as it empties to reduce air contact and splashing. That design is why they're the standard packaging for high-volume fluids that need to stay uncontaminated between draws — chemistry reagents, blood bank solutions, and ultrasound gel among them.

This collection covers the fluids you actually buy in cubitainer format. On the clinical side, McKesson Ultrasound Gel and McKesson Ultrasound Transmission Gel arrive in 5-liter cubitainers — clear, high-viscosity, latex-free formulas meant to refill smaller dispenser bottles at the point of care, so a busy imaging department isn't replacing single bottles all day. For labs, we carry reagent- and ACS-grade chemistry solutions including Thermo Fisher NERL Chemistry Reagents and StatLab ACS Grade reagents in 5-gallon sizes, plus Ek Industries ASTM Type I reagent-grade water in 20-liter volumes. Blood bank operations will find Fisherbrand Saline Immunohematology Reagent in a 10-liter cubitainer built for transfusion-service workflows.

Two questions come up most when buying at this scale. First, grade matters: reagent grade, ASTM Type I, and ACS grade are not interchangeable — match the spec to your assay or protocol before ordering. Second, dispensing: cubitainers work best with a spigot or pump tap, and the collapsing liner means you get near-complete drawdown with minimal headspace, which helps preserve reagent integrity over the container's use life.
