Quick facts
- United States: general purpose laboratory equipment reaches the device rules through 21 CFR 862.2050, which applies only to equipment "labeled or promoted for a specific medical use" that is "intended to prepare or examine specimens from the human body".
- United States: 21 CFR 862.2050 classifies that equipment as Class I, exempts it from premarket notification, and exempts it from the quality management system requirements "except for requirements concerning records and complaint files".
- United States: a general purpose reagent is reached separately through 21 CFR 864.4010, so a bench tool and a bench chemical are reached through two different sections.
- Canada: a device takes the classes in Schedule 1 to the Medical Devices Regulations, SOR/98-282, and equipment with no medical purpose is not a device unless it is represented for a medical purpose.
- Both countries: a magnetic stirrer that is sold as general laboratory equipment and never labelled for a medical use stays outside the device rules in both countries.
- Canada: regulation text cited here is current to 2026-10-03; the American equipment entry was amended 90 FR 55980, December 4, 2025.
A magnetic stirrer is the least dramatic item on a bench and one of the easiest to get wrong on a device list. It has no patient contact, no diagnostic function and no sterile claim. What decides whether either country reaches it at all is not what it does but what the maker says it is for, and that single trigger is where the two systems meet.
When does bench equipment become a regulated device?
When it is labelled or promoted for a medical use, and not before.
The American entry draws the line in one sentence. 21 CFR 862.2050 covers "general purpose laboratory equipment labeled or promoted for a specific medical use" and defines it as a device "intended to prepare or examine specimens from the human body and that is labeled or promoted for a specific medical use". A stirrer that is catalogued as a laboratory stirrer and nothing more does not meet that description. The same stirrer sold as a sample-preparation unit that is promoted for a medical application does.
That is why the label, the catalogue page and the instruction sheet matter more than the hardware for this class of item. A laboratory that buys a stirrer under a general-purpose catalogue entry and then uses it to prepare patient specimens has not turned it into a device by using it that way. What would change its status is the maker representing it for a medical purpose.
| Bench item | American entry | Device when |
|---|---|---|
| Magnetic stirrer, general catalogue | 21 CFR 862.2050 | Labelled or promoted for a medical use |
| Shaker for specimen preparation | 21 CFR 862.2050 | Labelled or promoted for a medical use |
| General purpose reagent | 21 CFR 864.4010 | Reached through the reagent entry |
| Hot plate without a medical claim | Not reached | No medical representation |
How does the American entry classify equipment it does reach?
As Class I, with a narrow carve-out from the quality rules that a laboratory should read closely.
Where the equipment is labelled or promoted for a specific medical use, 21 CFR 862.2050 classifies it as Class I under general controls. It is exempt from premarket notification, subject to the limits in § 862.9, and it is exempt from the quality management system requirements of part 820 "except for requirements concerning records and complaint files under § 820.35".
That final clause is the one that matters for a lab with a quality system. A Class I bench instrument sitting inside the quality system still generates a complaint file when a unit fails, and the record of that failure is the part of part 820 the entry does not exempt. A stirrer is not the item that breaks a quality system, but it is the item whose complaint file is easiest to forget because the unit looks like it belongs to the facilities budget rather than the device register.
Does Canada reach a magnetic stirrer the same way?
It reaches it through the same trigger, because equipment without a medical purpose is not a device in Canada either.
Schedule 1 to the Medical Devices Regulations, SOR/98-282 classifies devices that fall within the definition of a medical device. General laboratory hardware that is sold without a medical representation does not fall within that definition, so it does not take a class at all. A manufacturer that represents the same stirrer for a medical purpose brings it within the regulations, and the class is then reached by applying the rules to the intended use.
The practical effect is that both systems ask the same question first — what does the maker say this is for — and only then assign a class. The difference is where the answer is written down. The American side has an equipment entry that states the trigger and the class in one place. The Canadian side has the definition of a medical device and the classes in Schedule 1, and the route from one to the other is an application of the rules rather than a single named entry.
The safety standard beneath the hardware is a separate matter from the device rules. IEC 61010-1:2010 covers the safety requirements for electrical equipment used in measurement and laboratory use, and ISO 13485:2016 is the quality management standard that sits over a maker that does build instruments for medical use.
| Item | Canada | United States |
|---|---|---|
| Trigger that makes it a device | A medical purpose representation | Labelled or promoted for a medical use |
| Named entry for a stirrer | None | 21 CFR 862.2050 equipment entry |
| Class once reached | Applied from the Schedule 1 rules | Class I under the entry |
| Premarket route | Per the class reached | Exempt from prenotification |
| Records that survive the exemption | Per the quality system | Records and complaint files under § 820.35 |
What should a laboratory record for a bench instrument?
Five fields, and the one that decides the whole entry is the first.
- The intended use on the label. The catalogue description and the instruction sheet are what decide whether a device entry applies, so the file keeps the description rather than a paraphrase.
- The entry or rule relied on. A device register states the section for a reached device and records that no entry applies for one that is not reached.
- The complaint record. Where the item is a Class I device, the complaint file is the part of the quality rules that still applies.
- The electrical safety check. Portable-test records for bench equipment sit with the instrument, not with the room.
- The maintenance log. A stirrer that has failed a speed check is a stirrer that can skew a preparation step, so the check belongs on the record.
An instrument that is never a device is easy to leave out of the register, and an instrument that becomes one is easy to leave in the wrong column. Writing down the intended use first settles which of the two it is.
Which consumables sit beside the bench instrument?
The items that touch the specimen, which is where the bench work ends.
A preparation bench runs on specimen containers, swabs and the sheets that record what happened. The sterile graduated specimen cups carry the sample away from the bench, the 120 mL sterile screw-cap containers hold a larger volume, and the double-tipped cotton swabs cover the sampling step. A laboratory that also runs a steriliser pairs the sterilization monitoring collection with the biological indicator 5-pack trial. For clinics and multi-site groups buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers.

A bench instrument with no register entry is a bench instrument that cannot answer a question about itself. The printable bench equipment register is a free sheet with columns for the instrument, the intended use on the label, the entry relied on and the last safety check, so the trigger that decides the device question is written down once. The register generator built for a single laboratory sizes the sheet to the number of benches a laboratory runs. No account and no sign-up are needed to open either one.
Where the intended use of an instrument or the entry that applies to it needs to be set out for an inspection, a written answer is worth more than a general one. Ask a compliance specialist and a written answer comes back specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions
Is a magnetic stirrer a regulated device?
Only when it is labelled or promoted for a specific medical use. A stirrer sold as general laboratory equipment and never represented for a medical purpose is not reached by the device rules in either country.
What class does general purpose laboratory equipment take in the United States?
Under 21 CFR 862.2050, equipment labelled or promoted for a specific medical use is Class I, exempt from premarket notification and exempt from the quality management system requirements except for records and complaint files.
Which records survive the exemption?
The entry exempts the device from the quality management system requirements of part 820 except for requirements concerning records and complaint files under section 820.35.
Does Canada have a named entry for a magnetic stirrer?
No. Schedule 1 to the Medical Devices Regulations names no stirrer, so the device question turns on whether the equipment is represented for a medical purpose and the class is then reached by applying the Schedule 1 rules.
Where is a general purpose reagent reached?
Through 21 CFR 864.4010 in the United States, which is a separate section from the equipment entry, so a bench tool and a bench chemical take different routes.
Which safety standard applies to a laboratory stirrer?
IEC 61010-1:2010 covers the safety requirements for electrical equipment used in measurement and laboratory use, which is separate from the device classification question.
