A spore testing supplier in Ontario should answer five things before you place a first order: which biological indicator strain suits your cycle type, how the result is read and recorded, how fast replacement stock arrives, whether the product documentation matches what your inspector asks to see, and whether the supplier can support more than one site. Clinics that ask these questions up front avoid the common failure where a low-cost indicator arrives with no usable record trail.
CliniEco supplies 
24-hour rapid-readout biological indicators in 25, 50 and 100 packs, with a 5-pack trial for a first evaluation, so a practice can verify fit before committing to a year of stock.
Which biological indicator strain matches your sterilizer cycle?
Steam and unsaturated steam cycles are monitored with Geobacillus stearothermophilus spores; ethylene oxide and dry heat cycles use Bacillus atrophaeus. Ordering the wrong strain is the single most common purchasing error, and it is invisible until an audit. Confirm the cycle type on the sterilizer nameplate before ordering, and confirm the strain on the vial label when the box arrives.
How often does an Ontario dental practice run a spore test?
In Ontario, the RCDSO requires a biological indicator for each sterilizer on every day that it is used, and for each type of cycle used that day — daily monitoring, not weekly. The weekly baseline that many practice teams have read about is the CDC and AAMI ST79 standard in most US states, which is a different jurisdiction. A practice running five days a week therefore consumes roughly 250 indicators a year per sterilizer, not 52.
| Consumption driver | Typical value | Effect on annual order |
|---|---|---|
| Monitoring days per week | 5 | ~250 tests per sterilizer per year |
| Cycle types run per day | 2 (wrapped + unwrapped) | adds a second test on days both run |
| Sterilizers on site | 1–3 | multiplies the annual quantity |
| Failed-test retests | 1–2 per quarter | adds 4–8 units annually |
What should a supplier include with the first shipment?
- Lot number and expiry printed on the outer carton, not only the inner vial
- Instructions for incubation temperature and read time for the specific product
- A record format that matches the fields your regulator expects to see
- Written confirmation of the strain and the cycle type it monitors
How do lead times compare across Ontario suppliers?
Ask for the delivery window in writing, and ask what happens when a shipment is short. A practice that runs out of indicators stops monitoring, and a gap in the log is what an inspector notices first. Suppliers who hold Canadian stock typically ship in days; suppliers who drop-ship from overseas can take weeks and cannot recover a short shipment quickly.

Frequently Asked Questions
Which spore strain should I order for a steam autoclave?
Use Geobacillus stearothermophilus for steam and unsaturated steam cycles. Bacillus atrophaeus is used for ethylene oxide and dry heat. Ordering by cycle type prevents the most common mismatch.
How many biological indicators does a five-day Ontario clinic need per year?
About 250 per sterilizer per year, because monitoring is required on each day the sterilizer is used. Two sterilizers doubles that figure.
Can I start with a small quantity before committing?
Yes. A 5-pack trial at $12.99 with shipping included lets a practice run a week of monitoring and confirm the record workflow before ordering a larger pack.
Does a lower-cost indicator reduce compliance risk?
No. Price per unit matters less than whether the strain, lot documentation and record format satisfy the inspection requirement. A missing lot number is a documentation gap regardless of price.
