Quick facts
- United States: cell and tissue culture supplies have a named entry at 21 CFR 864.2240, described as "devices that are used to examine, propagate, nourish, or grow cells and tissue cultures".
- United States: the identification paragraph names tissue culture flasks, disks, tubes and roller bottles, together with slide culture chambers, perfusion and roller apparatus and cell culture suspension systems.
- United States: the section places them in Class I (general controls), and adds a conditional exemption: if the devices are not labelled or otherwise represented as sterile, they are exempt from the quality management system regulation in part 820 except for records and complaint files.
- Canada: Schedule 1 to the Medical Devices Regulations, SOR/98-282 names no culture flask. A flask placed on the market with an in vitro diagnostic use is an in vitro diagnostic device, and Rule 8 of Part 2 places all other IVDDs in Class I.
- Canada: where the flask is not placed with a diagnostic use, it is a non-invasive device and Rule 7(1) places all other non-invasive devices in Class I. The class is the same either way.
- Canadian regulation text used here is current to 2026-09-21 and last amended 2026-06-17, as stated on the official consolidation; the American section was last amended 90 FR 55981, December 4, 2025.
A culture flask is the least dramatic item on a laboratory bench. It is a moulded vessel with a vented cap, bought by the case, and it is rarely the subject of a regulatory question. In the United States it has a named section, and that section carries a condition that most buyers never read: whether the flask is represented as sterile decides whether the manufacturer is exempt from most of the quality system regulation. In Canada the flask has no named entry at all, and its class is only discovered by asking which family of rules it belongs to.
Do cell culture flasks carry the same class in Canada and the United States?
Yes, Class I on both sides, reached by two different structures.
The American entry is one section covering a family. Section 864.2240(a) identifies cell and tissue culture supplies and equipment as devices used to examine, propagate, nourish or grow cells and tissue cultures, and then names the articles it covers: slide culture chambers, perfusion and roller apparatus, cell culture suspension systems, and tissue culture flasks, disks, tubes and roller bottles. Section 864.2240(b) places them in Class I and exempts them from premarket notification subject to the limitations in 864.9.
Canada names nothing. A flask is assessed by what it is placed on the market to do. If it is supplied for use with an in vitro diagnostic process, it is an in vitro diagnostic device, and Rule 8 of Part 2 of Schedule 1 provides that if rules 1 to 7 do not apply, all other IVDDs are classified as Class I. If it is supplied only as laboratory glassware or plasticware with no diagnostic use, it is a non-invasive device and Rule 7(1) places all other non-invasive devices in Class I. The two routes lead to the same class, and a laboratory does not have to choose between them to know the class.
| Item | Canada | United States |
|---|---|---|
| Named entry for a tissue culture flask | None in Schedule 1 | 864.2240, cell and tissue culture supplies and equipment |
| Route where a diagnostic use is represented | Rule 8, all other IVDDs, Class I | 864.2240, Class I, general controls |
| Route where no diagnostic use is represented | Rule 7(1), other non-invasive devices, Class I | Outside the identification paragraph if no medical use is represented |
| Premarket notification | Not applicable at Class I | Exempt, subject to the limitations in 864.9 |
| Sterility claim | Does not change the class | Changes which quality system requirements apply |
| Articles named | None | Flasks, disks, tubes, roller bottles, slide chambers, perfusion apparatus |
How does the sterility claim in the United States change the obligation compared with the route in Canada?
This is the sharpest difference between the two frameworks, and it sits in a single sentence.
The American section carries a conditional carve-out. If the devices are not labelled or otherwise represented as sterile, they are exempt from the quality management system regulation in part 820 except for requirements concerning records and complaint files. Read the other way, a flask that is represented as sterile sits inside the quality system regulation, and a flask that is not sits outside it except for records and complaints.
Canada does not organise the obligation the same way. A Class I medical device is not exempt from the framework in the way an American Class I device can be; the framework applies according to the class, and the sterility of the contents is a matter for the manufacturer's processes and the labelling rather than a switch that turns the manufacturing framework on or off.
For a buyer, the practical consequence is a question about documentation. When a supplier states that a flask is sterile, that statement is doing regulatory work in the United States. A laboratory asking for a scope of supply should ask what the sterility claim is, whether it is a claim on the label or a process control, and what evidence supports it, because the answer is not the same on both sides of the border.
| Question | Canada | United States |
|---|---|---|
| Does sterility change the class | No | No |
| Does sterility change the quality system position | Not as a carve-out in the rules | Yes, for part 820 except records and complaints |
| What the buyer should ask for | The label and the intended use | The label, the intended use and the sterility statement |
| Where the class comes from | Rule 8 or Rule 7(1) | The named section 864.2240 |
What does a laboratory record for a Class I culture flask?
Five records, and the first one is the one that keeps the class defensible.
- The intended use. Whether the flask is supplied for use with an in vitro diagnostic process or as general laboratory plasticware, stated on the file rather than inferred.
- The sterility statement. The form in which sterility is claimed, whether on the label, in the certificate or in the instructions, kept with the batch record.
- The lot record. The lot or batch number of each case, so that a recall or a contamination investigation can be traced to physical stock.
- The storage instruction. The temperature and humidity the manufacturer states for the flask and its packaging, and the storage location the laboratory applies.
- The handling instruction. The opening, venting and disposal steps, filed with the working instruction rather than left in the catalogue.
A sixth item is worth adding where the laboratory cultures patient specimens rather than only reference strains. The record should state whether the flask is used with primary specimens, with a cell line, or with a quality control organism, because that use decides which decontamination and waste route applies at the end of the run, and because it is the fact an auditor will ask for when the flask is traced back to the specimen it carried.
Which consumables does a culture bench restock alongside its flasks?
Flasks and the consumables that run with them are ordered on the same cycle. 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 sterile specimen container covers the transfer step, the sterile centrifuge tubes cover the processing step, and laboratories that also run a steriliser can pair the monitoring collection with the biological indicator 5-pack trial.

A bench that records what it opens and when is easier to keep than one that records what it intends to. The printable A5 cycle log is a free A5 form built around a short cycle list, which suits a culture bench that runs a small number of loads. The generator that matches the bench load list builds that list from the number of loads a week and the vessel sizes involved, so the sheet matches the bench rather than a template. No account and no sign-up are needed to open either one.
Where the intended use recorded for a flask does not match the way it is actually used, the question is worth putting in writing. 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 tissue culture flask a regulated device in Canada?
It depends on the way it is placed on the market. Supplied for use with an in vitro diagnostic process it is an in vitro diagnostic device under Rule 8 of Part 2; supplied as general plasticware with no such use it is a non-invasive device under Rule 7(1). Both routes give Class I.
Why does the American section mention sterility?
Because the section carries a conditional exemption. Section 864.2240 exempts devices that are not labelled or otherwise represented as sterile from the quality management system regulation in part 820, except for requirements concerning records and complaint files.
Which articles does section 864.2240 cover?
It covers cell and tissue culture supplies and equipment, and names slide culture chambers, perfusion and roller apparatus, cell culture suspension systems, tissue culture flasks, disks, tubes and roller bottles.
Does the class change if the flask is sold sterile?
No. The class is Class I in both frameworks whether or not sterility is claimed. In the United States the sterility claim changes which quality system requirements apply rather than the class.
What should a laboratory keep for a Class I culture flask?
The recorded intended use, the form in which sterility is claimed, the lot or batch number of each case, the storage instruction and the handling instruction, filed with the working papers rather than left in the catalogue.
