No install, no sign-up, data stays on your device.
Offline-first lab management — samples, reagents, tasks & equipment
Key features
Sample management with auto-generated codes and status workflows
Reagent inventory with stock in/out history, low-stock & expiry alerts
Experiment tasks linked to samples and reagents, with priorities and due dates
Dashboard, equipment records, and full offline PWA with JSON backup
How it works
From opening LabFlow LIMS to getting results in three steps.
- 1
Register your inventory
Add samples, reagents, and equipment with auto-generated codes. Set low-stock thresholds and expiry dates so nothing slips through.
- 2
Track daily work
Create experiment tasks, link them to samples and reagents, and move items through guided status workflows with a full event history.
- 3
Stay on top of the lab
The dashboard shows low-stock and expiring reagents plus overdue tasks at a glance, and one-click JSON backup keeps your data safe.
Who is it for?
Three typical ways people put LabFlow LIMS to work.
Lab managers
Track samples, reagent stock levels, and equipment status in one place — no spreadsheets, no shared drives.
Research groups
Link tasks to samples and reagents, record every status change, and rebuild exactly what happened weeks later.
Individual researchers
A private lab notebook for your bench: register plasmids and strains, watch reagent expiry, and never lose track of a sample box.
Everything you can do
Sample management
Auto-coded samples (plasmids, strains, proteins, cells and more) with freezer/box/position storage, status workflows, and a full event timeline.
Reagent inventory
Stock in/out with movement history, low-stock alerts, and expiry tracking — batch numbers, vendors, and catalog numbers included.
Experiment tasks
Priorities, due dates, assignees, and links to the samples and reagents used, so every experiment is traceable end to end.
Equipment tracking
Register instruments and log usage, maintenance, and calibration records with next-due reminders.
Dashboard & alerts
Live statistics for samples, low stock, expiring reagents, and overdue tasks, plus a merged recent-activity timeline.
Offline & private
Installs as a PWA and works fully offline — all data stays in your browser's local storage and exports to JSON anytime.

Frequently asked questions
- Where is my data stored?
- Everything stays on your device. LabFlow LIMS runs entirely in your browser using local IndexedDB storage — no account, no server, and nothing leaves your computer. You can export a full JSON backup at any time.
- Does it work offline?
- Yes. After the first visit you can install it as a PWA and use every feature offline — registering samples, moving stock, and editing tasks all work without a network connection.
- What can I track with it?
- Samples (plasmids, strains, proteins, chemicals, cells, oligos), reagents and consumables with stock movements, experiment tasks linked to them, and lab equipment with usage, maintenance, and calibration records.
- Can I back up or move my data?
- Yes. The settings page exports your entire database to a single JSON file and restores it on any device or browser — ideal for migrating between computers or keeping scheduled backups.
- Is an online multi-user version coming?
- Yes, a cloud-based online LIMS with multi-user collaboration is planned. This offline version is built on the same data model, so your records will be portable when it arrives.
- How many records can it handle?
- It is designed for individual labs and small groups — comfortably thousands of samples, reagents, and tasks on a normal computer, all with instant local search and filtering.
