Solvent & Chemical Containment

STAINLESS STEEL IBCs

330-gallon all-stainless IBCs with a 316L wetted vessel — electropolished SS330-EP or passivated SS330-PV. One reusable body for high-purity solvents, semiconductor process chemicals, and specialty chemical service.

System Overview

The SS330 is a reusable 330-gallon IBC with a 316L stainless-steel vessel, built for high-purity solvents and for chemical service that calls for a metal body. The welded vessel, the protective cage, and the structural base stay in circulation — the container is cleaned and refilled, not replaced.

Two finishes share that one body. Electropolished SS330-EP serves semiconductor and contamination-sensitive work; passivated SS330-PV serves high-purity solvent and chemical service.

Up to 30% lighter

Optimized thin-wall construction takes up to 30% off the tare weight of a conventional stainless-steel IBC.

Relative tare weight. Conventional stainless-steel IBC = 100.

Lower lifetime cost

One vessel returns fill after fill. Reuse and a long service life reduce replacement and disposal costs.

  2. Ship
  3. Dispense

  5. Clean

Reusable in service. Recyclable as stainless steel at end of life.

Two Finishes. One Platform.

Both finishes are built on the same 316L vessel, cage, and base. The finish sets the wetted surface — choose it by the purity the chemical service demands.

Electropolished 316L — target Ra < 0.4–0.5 µm
What the finish does
Electropolishing dissolves the peaks of the surface profile, leaving a smoother wetted surface that is easier to clean between fills.
Built for
Semiconductor, ultra-high-purity solvent, and contamination-sensitive service.

What the finish does
Passivation removes free iron from the surface and restores the passive layer of the 316L, without changing the surface profile.
Built for
High-purity solvent and chemical service where corrosion resistance, cleanability, and service life set the requirement.

Materials & Construction

Select a number on the container to find each feature.

SS330 three-quarter view: brushed stainless vessel inside a stainless cage on a structural base, clamped fill opening on top and a ball valve at the bottom outlet

Top ports

A clamped fill opening and a second top port. Top-dispense configurations are fitted at the vessel top.

316L stainless-steel vessel

316L supplies the corrosion resistance, cleanability, and service life that high-purity solvent and chemical service require.

Structural base

A stainless base built for forklift movement, stacking, transport, and repeated use.

Protective cage

Kurko’s proprietary stainless-steel cage shields the vessel through handling and transport.

Welded interior

Fully welded and crevice-minimized — for efficient cleaning, low product hold-up, and contamination control.

2-inch bottom discharge valve

Bottom discharge as built. Top and bottom dispense configurations are matched to the chemical and the process.

Chemical Service

Stainless carries the liquids that do not belong in plastic — flammable and moisture-sensitive solvents first among them. The shell and cage are continuously conductive, so the vessel is its own grounding path.

Typical Chemical Service

Service is confirmed per chemical, concentration, grade, and seal configuration at qualification.

Ideal Applications

  • High-purity solvents
  • Semiconductor & electronics chemicals
  • Specialty & corrosive chemicals
  • Pharmaceutical & biotech processing
