Centrifuge tubes come in different materials, sizes, and volumes. Lab technicians use them to keep samples safe and to ensure centrifugation runs smoothly. Picking the wrong tube can mess up your workflow and contaminate samples. Before you buy centrifuge tubes, it’s worth considering a few things: chemical compatibility, maximum rotation speed, and the sample volume you need. The right tube makes experiments more reliable and keeps your samples protected.

Types of Centrifuge Tubes: Quick Overview

Choosing a good lab equipment supplier matters a lot. Labs can turn to BostonMed Supply and pick from a solid range of tested products. There are several different types of centrifuge tubes, and each one has its own strengths. The right type depends on what you’re spinning, how fast, and what chemicals are involved. Here’s a quick look at the main categories:

Round tubes – have a rounded bottom and work best for specific applications.
Plastic tubes – lightweight, chemically resistant, and usually safe for autoclaving.
Conical tubes – the most popular choice for collecting and concentrating sediment.
Glass tubes – better chemical compatibility, but more fragile.
Standard tubes – used for routine, everyday lab work.
Filter tubes – clean and filter samples during centrifugation.
Graduated tubes – have volume markings for precise measurement.
Ungraded tubes – used for special experiments where exact volume isn’t the priority.

Understanding the differences helps you pick what actually fits your protocol.

Conical Centrifuge Tubes

Conical centrifuge tubes are the most widely used tubes in labs – and for good reason. They come in standard sizes, such as 15 ml and 50 ml. The tapered bottom helps sediment collect right in the center, making it easy to pipette out. Most conical centrifuge tubes are made of polypropylene (PP), which is chemically resistant and can be autoclaved. Some are made from polystyrene (PS), which is more affordable but less durable.

Graduated centrifuge tubes in conical form let you measure sample volume right in the tube without any extra steps. Sterile autoclavable versions are great for clinical and cell culture work, where contamination is a real concern. The conical design, combined with volume markings, makes these tubes a reliable everyday tool.

Key specs:

Shape: Conical, tapered bottom
Material: PP or PS
Volume: 15-50 ml
Graduation: Graduation marks available
Sterility: Sterile or non-sterile options
Cap: Screw or snap
Common uses: Cell pelleting, sample storage, general separation

Glass Centrifuge Tubes

Glass centrifuge tubes are used when plastic just won’t cut it. If your sample reacts with plastic – for example, when working with organic solvents or strong acids – glass is the right call. These tubes are made from borosilicate glass, which handles high temperatures and aggressive chemicals without breaking down.

Centrifuge glass tubes are a go-to in pharmaceutical labs and chemical research, where chemical inertness is critical. That said, glass does have downsides: it’s fragile, heavier than plastic, and costs more. They’re available in both round-bottom and conical shapes, depending on the application.

Key specs:

Material: Borosilicate glass
Shape: Round-bottom or conical
Temperature: Handles high heat
Chemical resistance: Works with aggressive solvents
Fragility: Can break at high speed – handle carefully
Common uses: Pharma, chemistry, lipid extraction

Plastic Centrifuge Tubes: PP vs. PS vs. PET

Plastic centrifuge tubes are the standard in most labs. They’re light, chemically resistant, and available in both sterile and non-sterile versions. The three main materials are polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET), and each one is suited to different needs.

PP is the most durable and can handle a wider range of chemicals and temperatures. PS is more transparent and affordable, but less chemically resistant. PET sits somewhere in between. The right material depends on what you’re centrifuging and at what speed.

Key specs:

Material: PP, PS, or PET
Sterility: Sterile and non-sterile options
Speed: Compatible with both high and low RCF protocols
Clarity: Transparent or clear options available
Chemical resistance: Varies by material
Common uses: Standard lab applications across most fields

Filter Centrifuge Tubes

Filter centrifuge tubes are a practical option when you need to spin and filter in a single step. They use a membrane filter to separate and purify the sample while centrifuging. This is especially useful for protein concentration and buffer exchange. Different tubes have different molecular weight cutoffs (MWCO), so you can choose based on what you want to keep or remove.

Centrifuge filter tubes let labs combine what would otherwise be two separate steps into one, saving time and reducing the risk of handling errors. Well-known brands include Amicon, Vivaspin, and Corning Spin-X.

Key specs:

Membrane: PES or regenerated cellulose
Cutoff: 3K-100K MWCO
Common uses: Protein concentration, buffer exchange
Brands: Amicon, Vivaspin, Corning Spin-X
Efficiency: Filtration and centrifugation are done at the same time
Volume: Designed for small to medium samples

High-Speed Centrifuge Tubes

High-speed centrifuge tubes are built for ultracentrifugation and high-demand protocols. They have thicker walls and reinforced caps to safely handle extreme speeds. The tolerances on these tubes are tight, which is what makes them reliable at high RPM.

These tubes are made from materials like polypropylene or polycarbonate, depending on the application. It’s really important to match the tube to the rotor – using the wrong tube at high speed can cause it to crack or shatter, which is both dangerous and expensive. Always follow the manufacturer’s guidance on max RCF and rotor compatibility.

Key specs:

Walls: Thick and reinforced
Cap: Secure, reinforced closure
Material: PP or polycarbonate
Shape: Round-bottom or Oak Ridge style
Common uses: Subcellular fractionation, ultracentrifugation
Safety: Must be matched to rotor type

Graduated vs. Non-Graduated Tubes

Graduated centrifuge tubes have printed volume markings on the side. This makes it quick and easy to measure samples accurately without needing extra equipment. For any protocol where volume precision matters – like clinical diagnostics or aliquoting – graduated tubes are the obvious choice.

Non-graduated tubes are cheaper and totally fine for applications where you don’t need exact volume measurement. Choosing graduated centrifuge tubes when accuracy matters reduces measurement errors and speeds up sample prep. Most conical tubes come graduated by default, but it’s always worth double-checking before you order.

Key specs:

Graduation: Printed volume markings
Precision: High accuracy for aliquoting
Cost: Non-graduated versions cost less
Common uses: Clinical diagnostics, general lab work
Volume: 15-50 ml standard range
Material: PP or PS
Benefit: Fewer measurement errors, faster prep

How to Choose the Right Tube for Your Lab

Choosing the right centrifuge tube comes down to a handful of practical factors. Here’s how to think through it:

Sample type: Organic solvents need glass. Aqueous solutions work fine with plastic. If you need to filter while spinning, go with a filter tube.
Centrifuge speed: Low-speed protocols work well with PS or standard PP. High-speed or ultracentrifugation requires reinforced tubes designed for those conditions.
Sterility: If you’re working with clinical samples or cell cultures, sterile tubes are a must. For general chemistry or non-sensitive applications, non-sterile options save money.
Volume accuracy: If your protocol requires precise measurements, use graduated tubes. If not, non-graduated versions get the job done at a lower cost.
Budget: Bulk non-sterile options cost significantly less than individually packaged sterile tubes. For large-volume labs, buying in bulk often makes the most sense.

When in doubt, check the tube’s datasheet and make sure it’s compatible with your rotor and your chemicals before committing to a large order.

Top Brands and Where to Buy

When you’re ready to buy centrifuge tubes, it helps to know which brands are trusted in the industry. The most established names include Corning, Eppendorf, Falcon (Corning), Sartorius (Vivaspin), Millipore (Amicon), and Thermo Fisher (Nunc).

Common Mistakes When Buying Centrifuge Tubes

Getting the wrong tube is an easy mistake to make – and it can lead to cracked tubes, damaged rotors, or lost samples. Here are the most common issues to avoid:

Ignoring max RCF: Always check the tube’s maximum RCF rating. Exceeding it is how tubes break.
Using PS with solvents: Polystyrene is not compatible with many organic solvents. Use PP or glass instead.
Wrong MWCO for filter tubes: If your cutoff is off, your target molecule will either pass through or get stuck when it shouldn’t.
Skipping sterility checks: Clinical samples require sterile tubes. Don’t assume – verify.
Rotor mismatch: A tube that doesn’t fit your rotor properly is a safety hazard.
Not reading the datasheet: Manufacturer guidance exists for a reason. Following it prevents most of these problems.

Frequently Asked Questions

What is the difference between conical and round-bottom centrifuge tubes?

Conical tubes have a pointed bottom that collects sediment in a single spot – ideal for pelleting cells or precipitates. Round-bottom tubes are better suited for high-speed centrifugation where the stress distribution matters more.

Can I autoclave plastic centrifuge tubes?

Polypropylene centrifuge test tubes are autoclavable. Polystyrene and PET are not – they’ll deform under the heat and pressure.

How do I know which filter tube MWCO to choose?

Pick an MWCO based on the size of the molecule you want to keep or remove. If you want to retain a protein, choose a cutoff smaller than that protein’s molecular weight.

Are glass centrifuge tubes safe for high-speed centrifugation?

Glass tubes can handle moderate speeds, but they’re not rated for high-speed centrifugation. Pushing them beyond their limit is a safety risk.

How should I store centrifuge tubes to maintain sterility?

Keep sterile centrifuge test tubes in their original sealed packaging and store them in a clean, dry place. Always wear gloves when handling them to avoid contamination.
