About labmate.tools
labmate.tools is a free collection of browser-based calculators and bench tools for life science labs. It is independent and vendor-neutral: nothing on the site is sponsored.
THE DETAILS LAST UPDATED 12 OCTOBER 2026
What it is
One toolbox for the whole bench, listed by category: plates, calculators, converters, labels, cells and protein, printing and cytometry. Each tool does one job — track a plate as you pipette, scale a master mix, plan a dilution, count and seed cells, load a Western, print cryo labels, check a poster, design a flow panel — and shows its formula and a worked example on the page.
Who it is for
Grad students, technicians, postdocs and lab managers. The tools are built for an iPad at the bench and also work on a laptop or phone.
How it is made
- Free to use, with no subscription and nothing to sign up for.
- Every tool runs in your browser. What you type, and any file you open, stays on your device — see Privacy.
- Independent and vendor-neutral: dyes, instruments and label sheets from every maker are listed side by side, and no listing is paid for.
- New tools come from requests. Tell us the step that slows you down at hello@labmate.tools.
Where the values come from
- Formulas are the standard relations used in lab protocols — C₁V₁ = C₂V₂, mass = molarity × volume × molecular weight, RCF = 1.118 × 10⁻⁵ × r × rpm², cells/mL = mean count per square × dilution × 10⁴. Each is written out on its tool page.
- Microplate geometry (Plate Tracker 1:1 view) follows the ANSI/SLAS microplate standards: 127.76 × 85.48 mm footprint, 9 mm well pitch for 96-well and 4.5 mm for 384-well plates.
- Plate and flask areas (Cell Count & Seeding) are typical values for standard tissue-culture plastic. Makers differ slightly, so check your vessel's data sheet when it matters.
- Cryo label sheets take label sizes and grids from the makers' product pages. Margins aren't published, so they are estimated; the calibration page lines them up with your printer.
- Cytometer presets (Panel Designer) are published default or core-facility configurations, each linked to its source sheet on the tool page. Measured spectra come from FPbase (CC BY-SA 4.0); dye peaks from each maker's published tables. Spillover is an estimate — compensation always comes from single-stain controls.
- Protein standard series follow the usual BCA, Micro BCA and Bradford kit inserts.
- Poster sizes and checks use common conference print sizes and widely used guides for image resolution and printed text size.
How values are checked
- The worked example on every tool page is calculated with the tool itself, and rechecked when that tool changes.
- Reference tables are generated from the same data the tool uses, so the page and the calculator can't disagree.
- Anything not yet checked against a primary source is marked on its page (for example “check” on some cytometer presets).
- Every change is listed in the changelog, newest first.
What the tools don't do
They calculate and track; they can't see what's in the well. Follow your own protocol and your institution's rules, and keep your lab notebook or LIMS as the record.
