Planning the sequencer lab requirements for a new instrument almost always starts in the wrong place, with the instrument’s footprint. That is the easy part. Modern sequencers are, for the most part, benchtop or small floor-standing units that fit in a reasonable amount of space. The footprint rarely forces a renovation. What forces a renovation is everything around the instrument: conditioned and backed-up power, stable environment, the cold storage the reagents and samples require, and a network connection fast enough to move the data off the instrument. These are the requirements that get discovered late, after the purchase order is signed and a delivery date is set, and they are the ones this guide is built around.
The specific numbers, exact power draw, precise clearances, temperature tolerances, are instrument-specific and come from the vendor’s site preparation guide, which you should request and read before purchase, not on installation day. What follows is the set of requirements to plan for, why each matters, and the failure each one prevents, so that the site assessment happens while it can still change the decision. Confirming these before committing is part of the broader readiness question covered in Is Your Lab Ready for NGS? A Readiness Assessment.
Key Takeaways

Bench and Floor Space
Start with the obvious requirement, then keep going past it, because the footprint is where planning usually stops and it should not. The instrument needs its stated bench or floor area, but it also needs clearance around it for maintenance access, which the vendor specifies and which is easy to underestimate when a room is being packed efficiently. An instrument wedged into exactly its footprint cannot be serviced without moving it, and moving a sequencer is not trivial.
The requirement most often missed at this stage is not about the instrument at all: it is workflow separation. Library preparation, especially any step involving amplification, should be physically separated from areas where completed libraries and post-amplification product are handled, to control the contamination risk that can compromise results. Designing that separation into the layout from the start is far cheaper than retrofitting it into a room that was planned around the instrument alone. Space planning that accounts for workflow, not just equipment, is what distinguishes a functional sequencing lab from one that merely houses a sequencer.

Power, UPS, and Backup
Sequencers need clean, dedicated, adequately rated power, and they need protection against interruption. The specific electrical requirements, voltage, circuit rating, whether a dedicated circuit is required, come from the vendor and should be confirmed with facilities before installation. What is universal is the principle: a sequencing run can take hours to more than a day, and a power interruption partway through can cost the entire run, wasting not just the time but the reagents and the sample material committed to it.
This is why an uninterruptible power supply is not optional for a production instrument. Sized correctly, it protects a run in progress through a brief outage and provides a controlled shutdown window during a longer one. The sizing has to account for the instrument’s actual draw and the runtime you need to protect, which again is an instrument-specific calculation. Treat the UPS as part of the instrument purchase, not an afterthought, because the first time a run is lost to a five-second outage, its absence becomes the most expensive line item nobody budgeted for.
Temperature, Humidity, and Vibration
Sequencing instruments operate within a specified temperature and humidity range, and the stability of the environment matters as much as the setpoint. A room that holds a steady temperature is better than one that hits the target on average while swinging around it, because environmental drift during a run can degrade data quality partway through rather than producing a clean failure you would notice immediately. Confirm that the HVAC serving the space can hold the vendor’s specified range under real conditions, including on the hottest day of the year and when the room is occupied, not just under ideal test conditions.
Vibration is the environmental factor most often overlooked, and it can matter for sensitive instruments. Sources range from foot traffic and nearby equipment to building systems and external activity, and the effect depends on the instrument, its location in the building, and the floor structure beneath it. An upper floor near an elevator is a different vibration environment from a ground-floor slab. Where vibration is a concern, assess it before installation rather than diagnosing it after unexplained data quality problems appear, and the How to Plan for Vibration Control in Lab Buildings guidance covers how vibration criteria are set and controlled in laboratory spaces.
Network and Data Egress
A sequencer produces a large volume of data, and that data has to leave the instrument efficiently after every run. An undersized network connection turns into a bottleneck exactly when the instrument is most productive, forcing data to queue on local storage and, in the worst case, delaying the next run because the previous run’s data has nowhere to go. The network drop at the instrument, and the path from there to wherever the data is processed and stored, both need enough capacity to clear a run’s output comfortably in the window before the next run completes.
The requirement is not just raw speed at the instrument; it is a clear, provisioned path from the instrument to processing and storage, sized for burst transfer at run completion rather than average load. Plan the network as part of the site preparation, with input from whoever manages your institution’s network, because a data path that works for a single test run may not hold up under routine production. The full treatment of storage, compute, and the data pipeline the instrument feeds into is covered in Managing NGS Data: Storage, Compute, Retention, and Staffing.
Reagent and Sample Storage
The instrument’s environment is only part of the site requirement. The reagents and samples that feed it have their own storage needs, and cold storage is frequently the requirement that actually forces new equipment and the space and power to run it. Sequencing reagents and kits typically require refrigerated and frozen storage, and precious or irreplaceable samples often require ultra-low-temperature storage. A minus-eighty freezer is a substantial piece of equipment in its own right: it has a meaningful footprint, draws significant power, generates heat the room’s HVAC has to remove, and is itself a candidate for backup power, because the samples inside it can be as valuable as anything else in the lab.
Plan cold storage capacity for the program you expect to run, not just the first month, and plan it with room to grow, because freezer space fills faster than anyone predicts and adding a freezer later means finding both the floor space and the electrical capacity for it after the room is already committed. The cold storage requirement is a common example of the guide’s central point: the instrument fit was never the hard part.
A Site Readiness Checklist
The table below organizes the site requirements by system, with the failure each one prevents, as a starting checklist to work through with facilities before the instrument is ordered. Replace the general items with the specific figures from the vendor’s site preparation guide as you go.
System | What to Confirm | The Failure It Prevents |
Space | Footprint plus maintenance clearance; pre- and post-amplification separation | Uninstallable or contamination-prone layout |
Power | Dedicated, correctly rated circuit per vendor spec | Instrument that cannot be powered as delivered |
UPS and backup | UPS sized to the instrument draw and protected runtime | Runs lost to power interruptions |
Environment | HVAC holds the vendor range under real conditions; vibration assessed | Data degraded by environmental drift |
Network | Provisioned path sized for burst transfer at run completion | Data egress bottleneck stalling the next run |
Cold storage | Refrigerated, frozen, and ultra-low storage with room to grow; backup power considered | No place for reagents and samples; lost samples |

Run this assessment while it can still change the decision, not after the instrument has a delivery date. A site problem found during evaluation is a factor in the choice; the same problem found on installation day is an expensive emergency. The structured selection process this feeds into is covered in Choosing an NGS Platform: A Lab Manager’s Selection and Procurement Guide, and the broader operational picture of running the instrument once it is installed is in Next-Generation Sequencing in the Lab: A Manager’s Guide to Building, Budgeting, and Scaling NGS Capacity.
