CliniEco Medical Biological Indicator — 1-Hour Rapid Readout, Fluorescence, 50-Pack

Rapid-readout sterilization monitoring — results in 1 hour, not 24 hours.

The 1-hour vial answers a scheduling question, not a biological one: can this load go back into the chair before the day ends? Fifty self-contained vials (model ZJ60) arrive in one box, and every result is read on the CliniEco Rapid Reader at 58 ± 2 °C — there is no colour change to read by eye.

Which sterilizer cycles can a 1-hour biological indicator be used in?

Vacuum and gravity cycles both, on saturated steam at the three temperatures a Canadian clinic actually runs: 121 °C, 132 °C and 134 °C. The vial carries Geobacillus stearothermophilus ATCC 7953 at a population of at least 1.0 × 10⁶ c.f.u. with a D-value of at least 1.5 minutes at 121 °C, and it incubates at 58 ± 2 °C. The organism and the reference standards — ISO 11138-1 and ISO 11138-3 — are the same as our 24-hour line, so one sterilizer can run both tiers without splitting the monitoring programme or the logbook format. What changes is the wait, not the organism or the cycle it monitors.

How long does the 1-hour result take, and when can the load go back into use?

Sixty minutes from activation, with no overnight hold and no second visit. In practice: run the cycle, activate the vial, read it at the hour mark, and release the load if the result is negative. A positive result is a failed load and it stays failed — re-clean, re-pack, re-sterilize, and look at the sterilizer before it runs again. One indicator per load, every day the sterilizer runs, placed where steam is hardest to reach: in a dental load that means inside the pouch or cassette, not loose in the chamber.

What does the 1-hour tier cost per sterilization day, and how far does one box go?

A box of 50 vials, priced on this page, works out to a per-test figure by dividing the box amount by fifty. Monitoring that follows the pattern in RCDSO Standard 5542 for Ontario dental practices uses a test plus a control on each day the sterilizer runs, so a sterilization day consumes two vials and one box covers 25 such days. Per-day cost decides a tier: the 24-hour self-contained vial costs less per day, the 3-hour fluorescence vial sits below this tier per day, and the 20-minute vial sits above it.

Where the figure meets the logbook. The vial lot number goes against the load on the day of the test; the printable daily record on the compliance log centre has a column for it, and the compliance desk will answer a written question about your own sterilizer where the standard you follow reads differently. If you would rather work the number from your own case mix, the clinic supply planner multiplies sterilizer days by vials per day. Related tiers: 3-hour fluorescence 50-pack and 24-hour self-contained 50-pack. CliniEco Medical supplies this line under MDEL #35334.

Each vial contains Geobacillus stearothermophilus ATCC 7953 spores in a self-contained format. After the sterilization cycle the vial is activated and incubated, and the result is read by fluorescence — a positive (failed) and negative (passed) result is reported by the reader, not by eye.

How it differs from our 24-hour indicator

• Readout: 1 hour instead of 24 hours
• Reader required — this model is read on the CliniEco Rapid Reader (4-well fluorescence reader). It is not a colour-change product, so it cannot be interpreted visually.
• Same spore strain and same ISO reference as our 24-hour line, so both can sit in one monitoring programme.

Price per test, and when the 1-hour tier is worth it

Each of the three fluorescence 50-packs is priced on its own page, and the per-test figure follows there by dividing the box amount by fifty. Against the 20-minute tier this one costs less per test; against the 3-hour tier it costs more. Over 240 tests (two indicators per test day, 120 test days) the gap between adjacent tiers stays small enough that readout speed, not price, is the reason to move up or down a tier.

This is the tier for a load that has to be released inside the working session, but not inside the half hour: a normal clinic day of two or three cycles, or a shared reader where a 20-minute read would hold up the queue. If results can wait until the end of the day, the 3-hour indicator is cheaper; if the instruments are needed back immediately, the 20-minute one is faster.

Who it is for

Dental clinics, medical clinics and laboratories that run daily steam sterilization and need a same-day, documented result — for example where a load cannot be released until the biological indicator reads negative.

What you need with it

• CliniEco Rapid Reader — 4-well fluorescence reader (required for this model)
• Incubation at 58 ± 2 °C
• Batch record: record the vial lot number against the sterilizer load

Documentation

Manufacturer's instructions for use are supplied with every box. A certificate of analysis per batch is available on request — the lot number on the box is traceable to the release documentation.

How to run a test

1. Place the indicator in the load, in the area that is hardest to sterilize (for a typical dental load: with the instruments in the pouch or cassette).
2. Run the sterilization cycle as normal.
3. After the cycle, follow the vial activation step described in the manufacturer's instructions — the vial is activated, then incubated.
4. Place the vial in the CliniEco Rapid Reader and incubate at 58 ± 2 °C. The reader reports the result at the readout time above.
5. Record the result and the vial lot number against the sterilizer load log.

One indicator per load, every day. Do not add any label or tape to the vial or its cap — it interferes with the incubation and read.

Interpreting the result

• Negative (pass) — the spores were killed; the load may be released.
• Positive (fail) — spores survived. Do not release the load: re-clean, re-pack and re-sterilize, and check the sterilizer before using it again. Retain the indicator and the load record.
• This model is read by the reader only. Unlike our 24-hour indicator, there is no colour change to read by eye — the result must come from the reader.
