Benchtop vs. Floor Centrifuges: How to Choose the Right Format for Your Lab

Compare space, speed, and sample volume to find the right centrifuge format for your lab.

When setting up a new lab or upgrading equipment in a busy one, few decisions carry as much lasting impact as your centrifuge format. It’s not just about size. It’s about how your team works, what types of samples you process, and where the equipment will fit in your lab.

Benchtop centrifuges (also called tabletop centrifuges) are often seen as the default for space-conscious labs. But modern floor centrifuges have changed expectations. They’re compact, mobile, and efficient in multiple ways, offering faster sample processing, higher capacity, quieter operation, and smarter use of lab space. Some even roll neatly under a standard lab bench, freeing up valuable workspace. 

This guide breaks down the key differences so you can choose with confidence, whether you’re outfitting a research startup or expanding a high-throughput facility.

Why your centrifuge format matters

Lab space is always at a premium. Every square inch, from your benchtop to the floor layout, needs to be optimized for access, safety, and performance.

Benchtop centrifuges sit directly on lab benches and are easy to reposition. They’re a smart choice for low-to-medium throughput workflows.

Traditional floor centrifuges were once large, noisy, and stationary, requiring dedicated space and power support.

But modern floor-standing centrifuges have evolved:

• Compact footprints
• Wheeled bases for mobility
• Quiet, stable operation
• Under-bench compatibility that utilizes unused space

Think about how samples move through your lab. A centrifuge that rolls out when needed and tucks neatly away when not can free up workspace and make daily operations more fluid, especially when processing large batches, rotating users, or scaling protocols.

Benchtop centrifuges: Compact and convenient

Benchtop centrifuges are ideal for labs that need routine processing of moderate volumes. They’re lightweight, easy to set up, and require little infrastructure, making them popular in academic labs and small research teams.

Benefits

• Small footprint
• Quick installation and setup
• Portable and flexible for small teams
• Great for minipreps and similar workflows
  

Limitations

• Lower capacity (1.5–50 mL tubes) and fewer rotor options
• May struggle with high-speed or high-volume workflows
• Can create noise and vibration that disrupt nearby work
• Takes up benchtop space, limiting room for other equipment

For one or two researchers handling small batches, a benchtop centrifuge is efficient and cost-effective. But as your lab scales, the limitations may become roadblocks.

Floor centrifuges: High capacity, low footprint

Today’s floor centrifuges offer the throughput and flexibility needed in modern research environments, without the bulk.

Many models now feature:

• Slim, under-bench designs
• Quiet motors and stable operation
• Modular rotor systems for flexibility
• Built-in wheels for mobility
  

Key advantages

• Process 72+ samples in one run (vs. 12–24 for most benchtops)
• Accept a broader range of tube sizes
• Support higher speeds and g-forces
• Reduce vibration, enabling sensitive sample prep
• Maximize lab space by occupying unused floor or under-bench areas

Dr. Jianliang Xu’s team upgraded to a TOMY floor-standing centrifuge to eliminate workflow bottlenecks and handle a growing volume of samples more efficiently. With the ability to process full tube racks in a single run and roll the unit where it’s needed, their lab gained both speed and flexibility.

“What used to take 10 minutes now takes just 1 or 2. Everyone loves it—it brings us so much joy.”
— Jianliang Xu, Ph.D., Georgia State University

By switching to a high-capacity floor centrifuge, Dr. Xu’s 10-person team dramatically increased throughput without needing multiple machines. The result? Faster prep times, smoother lab rotations, and long-term cost savings.

Another long-time user shared:

“Reliable, quiet, and easy to move. I roll it next to the bench when I need it, then slide it back out of the way. I’ve trusted it for 25 years.”
— Simon Knight, Ph.D., Lab Manager

Modern floor centrifuges are designed to meet the needs of growing labs, offering capacity, speed, flexibility, and smarter use of space.

Key considerations before you buy

Still unsure which direction to go? Start with these questions:

• What are your average and peak sample volumes?
• Is bench space more limited than floor space, or vice versa?
• Do your workflows require cooling, high speeds, or rotor flexibility?
• How many users will share the equipment, and how frequently?
• Are there specific regulatory or compliance requirements?

When to choose benchtop or floor

Choose a benchtop centrifuge if you:

• Run a small lab with low-to-moderate throughput
• Mostly process routine prep samples (e.g., minipreps, pellets)
• Have limited users and don’t need rotor flexibility

Choose a floor centrifuge if you:

• Need to process large volumes or diverse sample types
• Share equipment among many users
• Want long-term ROI from high-capacity, modular performance
• Prefer a unit that fits under the bench, rolls out, and gets to work

Conclusion: Greater throughput without sacrificing space

With TOMY’s modern floor centrifuge, you no longer have to choose between capacity and footprint. This one model gives you high-volume performance, quiet operation, and a compact design that fits where you need it—under the bench or in shared lab spaces.

Whether you’re scaling up workflows, streamlining lab rotations, or replacing aging equipment, the TOMY MDX-310 gives you the performance you need, without sacrificing space or flexibility.
