How do I calculate cost per unit for an EO or gamma sterilization lot?

Start with Sterilization Cycle Capacity to get units per load, then divide the cycle's fixed cost across them. Gamma Dose Cost prices the contract dose charge per load, and for EO you add gas, aeration, and biological indicator testing. Because a cycle's cost is largely fixed, a half-full chamber can nearly double cost per unit, so load density is the main lever, run alongside Capacity Gap to check you are batching efficiently.

How long does EO aeration add to lot release?

EO Residual Hold Time estimates the aeration time needed to bring ethylene oxide and ECH residuals below allowable limits for your material and configuration, which can range from under a day to over a week for dense or high-absorption product. Lot Release Time then adds residual testing, bioburden, and documentation review. Product is effectively frozen inventory during aeration, so this number drives how much finished goods buffer you must carry.

What seal strength should a sterile barrier pouch meet?

Sterile Barrier Seal Strength evaluates peel strength against the range required by ISO 11607 and your validated process, typically on the order of 1 to 2 pounds per inch for medical pouches, balanced so the seal holds integrity but still peels cleanly without fiber tear. Too weak risks breach, too strong risks tearing the porous web on opening. Pair it with Packaging Scrap Cost so seal rejects show up as a per-lot dollar figure.

How do I size bioburden testing for a production ramp?

Bioburden Test Load converts your lot frequency and sampling plan into the number of bioburden and sterility-related tests per period, so you can staff the lab and reserve incubation capacity. As volume ramps, routine bioburden monitoring and quarterly dose audits for radiation product can outgrow lab capacity before the sterilizer itself is full. Run it with Production Ramp Readiness so testing does not become the release bottleneck.

How much does changeover cost me between sterilization runs?

Changeover Time captures the load, unload, cycle conditioning, and reconfiguration time between lots, which is idle chamber or cell time that carries fixed cost with no output. On EO systems, conditioning and humidification add significant non-productive hours per cycle. Multiply that time by your fixed hourly cost and you see why consolidating same-configuration product into fewer, denser cycles improves both Quote Margin and effective capacity.

How should I reserve for a sterility or barrier field complaint?

Field Complaint Reserve estimates money to hold per lot based on your complaint and integrity failure rate and the cost of investigation, potential recall, and replacement. Because a sterility escape can trigger a recall far larger than the lot value, even a very low rate justifies a reserve. Feed in Pouch Material Yield, Sterile Barrier Seal Strength, and Rework Cost so the reserve reflects your real barrier defect and rework history.
