Door entry systems for wet labs

Wet labs are among the most demanding environments to manage access for. They house hazardous chemicals, biological materials, irreplaceable samples, and high-value equipment, and unlike most commercial facilities, they operate around the clock with a constantly rotating cast of researchers, students, vendors, and auditors moving through the space.

The question of who can access a wet lab, which areas within it, and at what times touches on safety, regulatory compliance, intellectual property, and research integrity. Unfortunately, traditional key systems were never built to manage this. This guide covers what modern door entry systems can do for wet labs and what to look for when choosing one.

What is a wet lab? #

A wet lab is a laboratory where experiments are conducted using liquids, chemicals, and biological materials, as distinct from a dry lab, which is primarily computational. Wet labs are found across pharmaceutical and biotech companies, university research departments, clinical diagnostics facilities, and the growing network of life science incubators that provide shared lab space to early-stage startups.

The physical environment has direct implications for access control. Wet labs should have strict separation between zones otherwise cross-contamination is possible. These types of environments need controlled environmental conditions that unauthorized entry can disrupt, plus storage areas for hazardous materials that carry their own access requirements. In this scenario, a door entry system can make a world of difference.

What is a door entry system for a wet lab? #

A door entry system replaces or supplements traditional mechanical locks with electronically controlled access managed through software. In a wet lab, this typically covers multiple points across the facility, but we’ll get to that later.

When it comes to the physical technology, the core components are:

• Reader: it’s installed at the door and reads the credential presented.
• Controller: this piece of equipment processes the credential and signals the lock to open or stay closed. The Kisi Controller Pro manages up to four access points from a single device, which is especially suitable for facilities with multiple secured zones.
• Credentials: these are the means of authentication (e.g. mobile access, key cards, fobs, or QR codes for temporary visitors).
• Access management software: the central system where administrators configure permissions, set schedules, manage users, and review entry logs.

Most modern systems are cloud-based, meaning administrators can manage the entire facility remotely. For example, if you want to add a new researcher, revoke a former employee's access, or issue a temporary credential to a visiting auditor, everything happens instantly, from anywhere, without anyone having to be on-site.

Where to deploy entry systems across a wet lab facility #

Commonly known, a wet lab is not a single uniform space. There are different zones with different access requirements. Most facilities have secured access at several distinct points of the building such as:

• Main building or floor entrance: this is the first perimeter which establishes the baseline access control for all authorized users before any zone-specific restrictions apply
• Individual lab suites: in multi-tenant incubators, each company's space needs its own controlled entry to enforce separation between tenants and protect proprietary work
• Cold storage and sample rooms: freezer farms and sample archives house materials that are often irreplaceable, so access is typically appropriate only for specific researchers and lab managers
• Chemical and reagent storage: rooms that have hazardous materials should have an additional access layer, with entry limited to trained and authorized personnel
• Shared equipment rooms: fume hoods, tissue culture rooms, and high-value instruments can have access scheduled around bookings or tied to training certification
• Administrative and data areas: offices and server rooms that house sensitive research data warrant their own restrictions, separate from general lab access

Why wet labs need controlled entry #

Wet labs aren't your typical commercial space, and the access challenges that come with them reflect that, since a lot can go wrong when the wrong person gets in. Here are the main reasons:

Safety, compliance, and biosafety requirements #

Since wet labs work with biological materials, that means they operate under biosafety level designations (BSL-1 through BSL-4). Naturally, as the biosafety level increases, so do access control requirements. Normally, higher-level labs require restricted access whenever work is being conducted, self-closing doors, and documented records of who has entered restricted areas.

The common thread is that access control systems support the documentation obligations in these environments because they generate detailed access logs. This matters when inspections and audits require accurate records of who accessed a space and when, which is important for compliance purposes.

Protecting equipment, materials, and research integrity #

It is a given that wet labs contain things such as irreplaceable biological samples, hazardous chemicals, and high-value equipment. Any type of unauthorized access risks contamination, sample loss, equipment damage, or exposure to dangerous substances. That’s why controlled entry (including zone-level restrictions for cold storage and chemical storage areas) limits exposure to only the people who are authorized and trained to be there.

IP protection in shared and incubator settings #

Another thing to consider is that wet lab incubators often house multiple competing companies under one roof. These companies usually work on proprietary research at its most vulnerable stage, right before patents are filed or results are published. Without granular access control, the separation between tenants relies on physical walls and good faith. Door entry systems replace that assumption with enforcement. In this scenario, each tenant's lab suite has its own credentials, access schedule, and entry log.

Managing a rotating, multi-tier user population #

Let’s say that a wet lab might be accessed in a single week by principal investigators, postdocs, students, technicians, visiting researchers, vendors, cleaning crews, and auditors. Each category of people should have different appropriate areas and hours when they are in the facility. Unfortunately, if you plan to manage these schedules with physical keys it can become really complicated quickly. A cloud-based system allows administrators to issue role-based, time-limited credentials and revoke access instantly when someone's affiliation ends.

After-hours access and reduced human error #

In scientific fields, research usually doesn't stop at 5pm, so authorized researchers should have 24/7 access to active experiments. However, unstaffed hours are when lapses tend to occur because of propped-open doors, shared PIN codes, or even former researchers still holding keys.

Modern entry systems address both sides of this. They usually include things like automated locking, tailgating detection, and forced-open alerts that close the gaps that policy alone can't reliably prevent. With a door entry system for wet labs, the facility can be kept accessible to everyone who legitimately needs it, around the clock.

Key features in a wet lab door entry system #

A basic access control system won't cut it in a wet lab environment, so here are some of the features worth looking for.

Role-based access and scheduling #

The system should make it easy to define who can access which doors and when. It has to give you the capacity to update those permissions as roles, affiliations, and schedules change. For example, a principal investigator might have full facility access, but a visiting technician might get a single-use credential for a two-hour window. That granularity needs to be simple to configure and maintain for administrators.

Detailed access logs and audit trail #

Every entry event should be logged automatically (who, which door, what time) and stored in a way that's easy to retrieve and export. Regulated environments usually need to produce accurate physical access records during an inspection. A system that generates these logs as a byproduct of normal operation removes a significant administrative burden.

Remote management #

Lab administrators are rarely on-site around the clock, so the ability to add users, revoke credentials, unlock a door for a visiting inspector, or respond to a security alert from a phone or laptop is essential if you’re running a facility with lean administrative teams.

Visitor and temporary access management #

As mentioned before, a visitor won’t need the same level of access as a full-time employee. They usually need scoped, short-term access without permanent credentials. Temporary solutions are QR codes or time-limited access links that expire automatically and handle this cleanly, without adding to the permanent user list or creating credential management overhead.

Touchless and hands-free access #

Researchers frequently work with gloved hands or are carrying equipment, so mobile credentials that allow a wave-to-enter interaction (where the door unlocks without requiring the user to retrieve a card or touch a reader) reduce friction in a way that is genuinely relevant to the lab environment. The Kisi Reader, for example, enables contactless unlocking with a simple hand wave.

Emergency and fail-safe design #

Access control must never impede emergency egress, especially in a sensitive environment like a wet lab. Systems should support fail-safe configurations that guarantee free exit at all times, and administrators should be able to remotely unlock or override doors when needed.

Offline reliability and integrations #

The system should continue to make access decisions locally during network outages so that researchers cannot be locked out of active experiments because of a connectivity issue. For institutions managing large or frequently changing user populations, SSO and SCIM integration are useful because they ensure that access provisioning stays in sync with HR and identity systems automatically.
