Quick facts
- United States: a micropipette is covered by 21 CFR 862.2050, "General purpose laboratory equipment labeled or promoted for a specific medical use," product code JRC, Class I.
- United States: that entry is self-limiting. It covers equipment "intended to prepare or examine specimens from the human body and that is labeled or promoted for a specific medical use," so the label and the promotion decide whether the rule is engaged.
- United States: the same entry is the umbrella for analytical balances (JQO), pH meters (JQY), centrifuges (JQC) and blood-tube mixers (GLE), all Class I.
- Canada: there is no named pipette entry. A pipette that simply dispenses liquid does not meet the Food and Drugs Act device definition, because it has no medical purpose of its own.
- Canada: once a pipette is used inside a regulated testing pathway, it sits under the laboratory's own quality system rather than under a device classification of its own.
- Both countries: the technical requirements for the instrument come from the ISO 8655 series, which fixes the gravimetric test method and the accuracy and precision limits.
A micropipette is the most-handled instrument in a clinical laboratory and the least-examined at the procurement stage. It is bought by volume range, it is calibrated on a schedule, and it is almost never classified, because on both sides of the border the answer depends on a sentence that most buyers never read: what the pipette is labelled to do. This article sets out the American umbrella entry, the Canadian position, and the parts of ISO 8655 that decide whether the instrument on the bench is fit for the volume it is used to measure.
Is a micropipette a regulated device in Canada and the United States?
In the United States the answer runs through a single regulation. 21 CFR 862.2050 covers "general purpose laboratory equipment labeled or promoted for a specific medical use," and defines it as a device "that is intended to prepare or examine specimens from the human body and that is labeled or promoted for a specific medical use." A micro pipette carries product code JRC and is Class I under that entry. The wording is what matters: the regulation reaches equipment that is both intended to handle human specimens and labelled or promoted for a medical use, so a pipette sold into a general industrial setting and one sold into a hospital laboratory are treated by reference to their intended use and their claims.
Canada writes no pipette entry at all. The Medical Devices Regulations classify devices through the Food and Drugs Act, and Health Canada summarises the device definition as covering health or medical instruments "used in the treatment, mitigation, diagnosis or prevention of a disease or abnormal physical condition." A pipette that measures and transfers liquid does not, by itself, do any of those things. It becomes a regulated device only if it is intended for a medical purpose and promoted as such, which is the same intended-use logic the United States applies, reached through a different instrument.

What does ISO 8655 require of a piston pipette?
ISO 8655 is the series that governs piston-operated volumetric apparatus, and two parts matter most at the bench. Part 1 sets terminology, general requirements and user recommendations, and Part 2 covers pipettes. A third part, Part 6, sets out the gravimetric reference measurement procedure that a laboratory uses to check the volume a pipette actually delivers.
The practical content of the series is the tolerance. Each nominal volume carries a maximum permissible error and a repeatability figure, and a pipette is in specification only when it holds both. That is why a calibration record that reports a single number, without a repeatability figure and without the test conditions, cannot show that the instrument is fit for use. The gravimetric method in Part 6 also fixes the inputs that change the answer: water temperature, air pressure, evaporation, and the balance used to weigh the dispensed water.
| Nominal volume band | What the tolerance covers | What the record should show |
|---|---|---|
| Small volume, sub-100 microlitre | Maximum permissible error and repeatability at the nominal volume | Measured volume, repeatability, water temperature, balance used |
| Mid volume, 100 to 1000 microlitre | Same two figures, checked at the nominal setting | Nominal and measured volume, test date, technician |
| Large volume, above 1000 microlitre | Same two figures, with tip fit recorded | Tip part number, measured volume, repeatability |
How do pipette calibration rules differ between Canada and the United States?
Calibration is a laboratory duty in both countries, but it is owed to a different kind of authority. In the United States, a laboratory that holds a Clinical Laboratory Improvement Amendments certificate is inspected against the condition-level requirements that include equipment maintenance and calibration. In Canada, a laboratory is typically accredited, and the accreditation standard that medical laboratories work to is ISO 15189, which places the pipette inside the laboratory's own equipment management and measurement-traceability system.
The difference is worth stating plainly for a procurement file. In the United States, calibration expectations flow from the laboratory's regulatory oversight under CLIA. In Canada, they flow from the laboratory's accreditation standard and from the provincial licensure of the laboratory. Neither route changes the pipette into a higher-class device, and neither route removes the need for a traceable calibration record.
Which pipette sizes and tips should a clinic stock?
Three decisions cover most clinical laboratories, and each one should be recorded rather than assumed.
- The volume range. A small-volume pipette for sub-100 microlitre work, a mid-range pipette for routine serum and reagent handling, and a larger pipette where bulk liquid is transferred. Buying a single wide-range instrument to cover all three is the usual source of tolerance failures at the low end.
- The tip fit. The tip is part of the volumetric system. A tip that does not seal properly changes the delivered volume even when the pipette itself is in calibration, which is why the record should name the tip part number alongside the pipette.
- The colour code. Pipette and tip colour codes are used to signal the matching volume range, and a stocking list that mixes codes without a legend is the record that fails first at an inspection.
What should a laboratory record for its pipette fleet?
Five records, each tied to a requirement rather than to a preference.
- The instrument register. Every pipette by serial number, with its nominal volume and the location where it is used.
- The calibration certificate. The gravimetric result, the repeatability figure, the conditions under test, and the reference to ISO 8655.
- The tip cross-reference. The tip part number that goes with each pipette, so that a delivered carton can be checked against the register.
- The service interval. The date of the last check and the date of the next one, because an out-of-date certificate is a finding whether or not the instrument is accurate.
- The intended-use statement. What the pipette is labelled and promoted to do, since that sentence is what decides the device question in the United States.
Which consumables sit beside the pipette line on a laboratory order?
Laboratory consumables are ordered as a cycle, and the pipette line travels with the specimen handling and incubation lines. For laboratories and clinics 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 CliniEco laboratory range gathers the specimen and bench consumables, and a laboratory that wants the pipette and specimen lines together can start from the lab consumables and pipette pack, the graduated specimen cups or the biological indicator five-pack trial for sites that also run their own sterilizer.

Frequently Asked Questions
What class is a micropipette in the United States?
Class I. A micro pipette carries product code JRC under 21 CFR 862.2050, the general purpose laboratory equipment entry, and is exempt from premarket notification subject to the limitations in 862.9.
Is a micropipette a medical device in Canada?
Not by default. A pipette that measures and transfers liquid has no medical purpose of its own, so it does not meet the Food and Drugs Act device definition unless it is intended for a medical purpose and promoted as such.
What does 862.2050 actually cover?
It covers general purpose laboratory equipment intended to prepare or examine specimens from the human body that is labelled or promoted for a specific medical use. Analytical balances, pH meters, centrifuges and blood-tube mixers are all classified under the same entry.
Which standard fixes pipette accuracy and precision?
ISO 8655. Part 1 sets terminology and general requirements, Part 2 covers pipettes, and Part 6 sets the gravimetric reference measurement procedure used to check delivered volume.
Does calibration change the device class?
No. Calibration is a laboratory duty. In the United States it flows from the laboratory's CLIA oversight; in Canada it flows from the accreditation standard, typically ISO 15189, and from provincial laboratory licensure.
Why record the tip part number with the pipette?
Because the tip is part of the volumetric system. A tip that does not seal changes the delivered volume even when the pipette is in calibration, so the record should name the tip alongside the instrument.
