Buying cell culture equipment and cell culture lab equipment in the order that lets work start: why a cell culture hood and a lab incubator or cell culture incubator have to be in and certified before anything else, what to look for in cell culture plates and vessels, and the items whose absence stops a culture laboratory

The order to buy in

1. Containment and incubation first. A biosafety cabinet certified in place, and a carbon dioxide incubator with a decontamination cycle. Both have lead times, both need siting decisions about heat and airflow, and neither can be improvised. Nothing else in the room matters until they are working.
2. Then the separations used every day. A benchtop centrifuge with a swing-out rotor for tubes and plates, refrigerated if primary cells or proteins are involved. This is the item a growing laboratory queues for first, so size it for the people rather than for today's samples.
3. Then cold storage with alarms. A laboratory refrigerator, a minus twenty and a minus eighty with monitoring and an alarm somebody receives, plus nitrogen storage for cell banks. Cell stocks are the laboratory's real asset and the failure plan belongs in place before the first vial goes in.
4. Choose vessels and plates from the assay, not the catalogue. Surface treatment, well geometry, optical bottom and lid design all change results. An assay read on an imager needs an optical bottom; a suspension culture needs an untreated surface. Standardise on as few formats as the work allows.
5. Buy the small things that stop work. A water bath or bead bath, a pipette controller per cabinet, aspiration with a trap, a cell counter, and enough plasticware to work for a term. A laboratory with an incubator and no serological pipettes cannot start.

Siting the room around the heat

Incubators, freezers and centrifuges all reject heat, and a small room full of them warms until everything runs continuously. Check the room's cooling capacity against the equipment list before ordering rather than after.

Put the microscope next to the incubators and the cabinet. A culture instrument across the room is a culture instrument used less often, and cultures checked less often fail more often.

What to share and what to own

Own the cabinet, the incubator, the centrifuge and the microscope, because they are used daily. Share imaging, cytometry and sorting, which are intermittent, expensive and much better with an expert beside them.

Nitrogen storage is worth centralising where a building allows it, because the monitoring, the filling and the safety arrangements are easier to do once and properly than in every laboratory.

Common questions

What cell culture equipment comes first?

A certified biosafety cabinet and a carbon dioxide incubator. Both have lead times and siting requirements, and no culture work can begin until they are installed and the cabinet has been certified in place.

How do I choose cell culture plates?

From the assay. Surface treatment decides attachment, optical bottoms are required for imaging, and well geometry changes edge effects and evaporation. Standardise on as few formats as the work allows to keep the stock manageable.

How much cold storage does a new culture laboratory need?

More than current need, with monitoring, alarms and a written failure plan before the first vial. Cell banks are the irreplaceable asset, and the day a freezer fails is the wrong day to find out where their contents would go.

What is most often forgotten?

The consumables and the small equipment: pipette controllers, aspiration with a trap, a counter, and enough plasticware. They are cheap, they have lead times, and their absence stops a fully equipped laboratory from working.
