Quick facts
- A hot plate, a magnetic stirrer, a thermostated cuvette holder and a micropipette are the same hardware whether they sit in a teaching laboratory or a hospital laboratory. What changes is the claim attached to them.
- United States: 21 CFR 862.2050 covers general purpose laboratory equipment labelled or promoted for a specific medical use. The identification is a two-part test: the device must be intended to prepare or examine specimens from the human body, and it must be labelled or promoted for a specific medical use.
- The consequence: the same hot plate sold without a medical claim is not a device under that section at all. Sold with a specimen-preparation claim, it is Class I, exempt from premarket notification subject to 21 CFR 862.9.
- Canada: there is no "general purpose" carve-out. Whether the equipment is a device depends on the purpose in the Act's definition, and an active laboratory device that is not caught by another rule is Class I under Rule 12 of Schedule 1 to the Medical Devices Regulations.
- Two Canadian add-ons raise the class: Rule 7(2)(a) for a device that calibrates, tests or supports quality control of another device, and Rule 7(2)(b) for a device intended to be connected to an active device classified Class II, III or IV.
- The claim on the box is therefore the single most important document in this category, in both countries.
Laboratory catalogues do not separate medical devices from general equipment. A bench hot plate and a stirring plate appear in the same section, often on the same page, and a laboratory buys them by specification rather than by regulatory status. The problem is that regulatory status follows the claim, and the claim is written by whoever writes the catalogue copy. This article sets out where the boundary sits in each country and what a laboratory should be able to show for the bench hardware it already owns.
Which items does this category cover?
The category exists because a laboratory instrument can be medical, general, or neither, depending on use.
- Heating and stirring. Hot plates, magnetic stirrers, heating blocks and combination units used to dissolve, warm or mix reagents and specimens.
- Volumetric transfer. Micropipettes and pipettors used to move measured volumes of reagent or specimen.
- Optical measurement support. Thermostated cuvette holders and cell holders used with a spectrophotometer or colorimeter.
- Bench support. Racks, baths, and the general apparatus that holds specimens during preparation.
The dividing line is not the item. It is the sentence next to the item.
How do the two countries decide whether the equipment is a device?
The two systems answer the question from opposite directions.
| Item | Canada | United States |
|---|---|---|
| Hot plate or magnetic stirrer | Device only if sold for a medical purpose; Rule 12 Class I | 21 CFR 862.2050 Class I if labelled or promoted for a specific medical use |
| Thermostated cuvette holder | Rule 12 Class I; Rule 7(2)(b) Class II if connected to a Class II or higher active device | Filed under 21 CFR 862.2050 in the classification database |
| Micropipette | Rule 12 Class I; Rule 7(2)(a) Class II if sold as a calibration or quality control support | Filed under 21 CFR 862.2050 in the classification database |
| Same equipment with no medical claim | Not a device | Not a device under the section |
| Quality records attached | Licence class obligations where a device | Records and complaint-file obligations under 21 CFR 820.35 for exempt equipment |
The American test is explicit in the section title: equipment that is general purpose falls under 21 CFR 862.2050 only when it is labelled or promoted for a specific medical use. The identification paragraph repeats the condition, and the classification paragraph then places the device in Class I, exempt from premarket notification subject to the limitations in 21 CFR 862.9, and also exempt from the quality management system requirements except for the requirements concerning records and complaint files.
Canada reaches the same shelf by a different route. There is no clause that says "general purpose". The question is whether the article is a device as defined, which turns on the purpose for which it is sold, and then which rule catches it. An active device that is not caught by Rules 8 to 11 falls to Rule 12 and is Class I.
What does the two-part test in 862.2050 actually require?
It requires both limbs, and that is the part most often read past.
- Limb one: intended to prepare or examine specimens from the human body. A hot plate used to warm a buffer is not preparing or examining a specimen, however useful it is in a laboratory.
- Limb two: labelled or promoted for a specific medical use. A catalogue entry that says "for laboratory use" or "for specimen preparation" is doing different work from one that says "for heating liquids".
A product that fails either limb is not a device under that section. That does not make it unregulated in every sense, because it is still equipment in a workplace and subject to employment, electrical and general product safety rules. It simply means the medical device route is not the route it is on.
A product that passes both limbs is in Class I, exempt from premarket notification subject to the limitations in 862.9, and carrying limited quality-management obligations. The exemption is not a licence, and the record obligations that survive are the ones a laboratory will be asked about after an incident.
Read as a decision, the two limbs resolve quickly:
| Question | If the answer is yes | If the answer is no |
|---|---|---|
| Is it intended to prepare or examine specimens from the human body? | The second limb has to be met | Not a device under 21 CFR 862.2050 |
| Is it labelled or promoted for a specific medical use? | Class I, exempt from premarket notification subject to 21 CFR 862.9, with records and complaint-file obligations | Not a device under that section |
| In Canada, is it sold for a medical purpose? | A device; Rule 12 Class I unless another rule catches it | Not a medical device under the Regulations |
| Is it sold as calibration or quality-control support? | Rule 7(2)(a) Class II in Canada | The base rule applies |
Where does the Canadian analysis land?
Canada does not have a "general purpose" carve-out, so the analysis is shorter but stricter in one respect: the sale purpose is the trigger rather than the wording of a catalogue heading.
- Sold for a medical purpose. The article is a device. An active laboratory device with no other applicable rule is Class I under Rule 12.
- Sold as calibration or quality-control support. Rule 7(2)(a) raises it to Class II, because the device is intended to act as a calibrator, a tester or a quality control support to another medical device.
- Connected to a Class II or higher active device. Rule 7(2)(b) raises it to Class II, which catches holders and modules that plug into an analyser.
- Sold with no medical purpose. It is not a medical device, and the Medical Devices Regulations do not apply to it.
That last point is the one practitioners find surprising, because it means the same bench hardware can move between regimes without a single change to its construction.
What should a laboratory be able to show for bench hardware?
Five items.
- The purchase specification or catalogue page. This is the document that records the claim the equipment was bought under.
- Where it is used. A hot plate used only for reagent preparation is in a different position from one used to prepare specimens.
- The connection map. What each module plugs into, because Rule 7(2)(b) in Canada and the parent-device logic in the United States both turn on connections.
- The temperature verification record. Where a heating device supports a method, the verification belongs with the method.
- The complaint file. Where equipment is exempt but still carries record and complaint obligations, the complaint file is the record that survives.
Which consumables does a general laboratory bench use?
A general bench restocks pipette tips, tubes, containers, gloves and cleaning supplies in the same cycle as its instruments. For laboratories 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. The laboratory consumables line covers bench preparation, the sterile 15 mL centrifuge tubes cover sample handling, and laboratories that also run an in-house sterilizer can start with the biological indicator 5-pack trial and the sterilization monitoring collection.

Frequently Asked Questions
When does a laboratory hot plate become a medical device in the United States?
When it is intended to prepare or examine specimens from the human body and is labelled or promoted for a specific medical use. Both conditions must be met for the equipment to fall within 21 CFR 862.2050. Equipment sold without a medical claim is not a device under that section.
What class is general purpose laboratory equipment in the United States?
Class I, where the section applies. 21 CFR 862.2050 classifies the equipment as Class I, exempt from premarket notification subject to the limitations in 21 CFR 862.9, and also exempt from the quality management system requirements except for those concerning records and complaint files.
Does Canada have an equivalent carve-out for general purpose equipment?
No. There is no general purpose provision in the Medical Devices Regulations, so whether the equipment is a device depends on the purpose for which it is sold. An active laboratory device that no other rule catches is Class I under Rule 12 of Schedule 1.
What raises the class in Canada?
Two subrules do most of the work. Rule 7(2)(a) classifies a non-invasive device as Class II if it is intended to act as a calibrator, tester or quality control support to another medical device. Rule 7(2)(b) classifies a non-invasive device as Class II if it is intended to be connected to an active device classified Class II, III or IV.
Is a micropipette regulated?
It can be. In the United States, a micro pipette appears in the FDA classification database under 21 CFR 862.2050. In Canada a pipette is an active device reached by Rule 12, and if it is sold as calibration or quality control support for another device it is raised to Class II by Rule 7(2)(a).
What is the most important document for this category?
The purchase specification or catalogue page. It records the claim the equipment was bought under, and the claim is what decides whether the equipment is a device in both countries. A laboratory that cannot produce the claim it bought under cannot show which regime applied.
