Biological Indicator 5-Pack Trial — CliniEco Medical

$14.99 — shipping included across Canada

Same 24-hour biological indicators as our regular 25-pack. Try a full week of daily spore testing — no commitment.

How the trial works: Add this item to your cart — the 5-pack trial is $14.99, shipping included. Applicable taxes apply. One trial per clinic, please. This is the identical BI you can reorder in our 25-pack (CLI-STER-BI-25).

Why a trial?

We're a Canadian medical supply brand (Health Canada MDEL #35334) and we want you to test our biological indicators in your sterilizer before you commit. 5 indicators = one full work week of daily spore testing. If you like them, reorder the 25-pack at about $2.80 per test.

Are you a clinic, dental practice, care home or lab?

You do not have to pay for this. We ship the same 5-pack free to verified facilities and cover the postage ourselves. Fill in the short application and we will review it and send it out, usually within one business day.

5-pack trial vs the 25-pack: which one do you order next?

The 5-pack trial is sized to let a clinic run the test on its own sterilizer and see how the log, the incubation and the readout fit the existing routine. Once that is settled, the 25-pack is the working size for a single sterilizer on daily monitoring; a multi-sterilizer site steps up again from there.

What to compare	5-pack trial	25-pack
How it is used	To evaluate the test and the routine before committing	Routine daily monitoring for one sterilizer
Approximate coverage	A short trial run	About a month of daily testing on one unit
Log and records	Same log fields as the working pack	Same fields, at the volume you will actually file
When it suits	A first order, or a switch from another brand	Steady-state ordering after the trial

Choosing the right option for your clinic

Before you order, the decisions that actually change the result are what a spore test proves, which organism applies to which cycle, and how the result fits a release decision. The full buyer's guide covers them step by step: Biological Indicators Explained: The Gold Standard of Sterilization Monitoring.

Frequently Asked Questions

How fast do these biological indicators give a result?

24 hours of incubation at 56-60 C, with purple meaning negative and yellow meaning positive. The 5 indicators in the trial pack cover one full work week of daily spore testing.

Which organism is used and to which standard?

Geobacillus stearothermophilus ATCC 7953 in a self-contained indicator built to ISO 11138-1 and ISO 11138-3. The same indicator is supplied in the 25-pack (CLI-STER-BI-25) if you reorder.

Which sterilizer cycles can this indicator monitor?

121 C gravity and 132-135 C vacuum-assisted steam cycles. It is not intended for ethylene oxide or hydrogen peroxide cycles.

Do I need an incubator to read the result?

Yes, a 56-60 C incubator, either the CliniEco 24-hour incubator or the unit already in the practice. The indicator is self-contained, so no separate media ampoule is handled at read time.

How does the trial price compare with the 25-pack?

The trial is 14.99 Canadian dollars for 5 indicators, about 3.00 Canadian dollars each, and the 4-pack of trials is 59.96 Canadian dollars for 20. The 25-pack reorder works out to roughly 2.80 Canadian dollars per test.

Is the trial limited to one pack per clinic?

Yes, one 5-pack per clinic is the intended use, which gives 5 daily tests. Verified facilities can also apply through our biological indicator sample request page for the same 5-pack.

What does the trial cost?

$14.99 for 5 indicators, shipping included — that is one full work week of daily spore testing. Applicable taxes apply.

Do I need a special reader?

No. These are 24-hour indicators — incubate at 56–60°C in any standard BI incubator. (We also stock a 3-hour fluorescent rapid-readout line for same-day results.)

Is this the same product as the 25-pack?

Yes — identical. The trial lets you verify compatibility with your sterilizer before reordering.

How many trials can I order?

One per clinic, so we can keep offering trials to more clinics.

Shipping time?

Orders ship from Toronto within 1-2 business days via Canada Post.
