Local-first lab utility
BufferPrep
Calculate and scale common lab buffer recipes locally in your browser.
BufferPrep helps you prepare common laboratory buffers such as PBS, TAE, TBE, TE, TBS, TBST, SSC, and EDTA stocks. Enter your desired final volume and concentration to generate a reagent table, bench protocol, and printable recipe.
All calculations run locally in your browser. No login, no upload, no server-side calculation.
Printable protocols
Generate clear, bench-ready instructions for routine preparation work.

Start from common formulations and verify against your lab protocol.
Saline buffer
PBS
Scale a common 10X PBS formulation for bench preparation and dilute to working concentration as needed.
Electrophoresis buffer
TAE
Scale a common 50X TAE stock recipe for electrophoresis workflows.
Electrophoresis buffer
TBE
Scale a common 10X TBE stock recipe for electrophoresis applications.
Storage buffer
TE
Prepare a common 1X TE buffer using Tris and EDTA stock references.
Scientific use note
- What this tool does: scales common fixed buffer recipes, calculates stock dilution volumes, or calculates mass from molarity, volume, and molecular weight.
- What this tool does not do: replace institutional protocols, validate sterility, provide clinical or manufacturing-grade validation, calculate arbitrary pH recipes in v1, or replace SDS/MSDS review.
- Research-use reference only. Verify all calculations against your institutional protocol before use. Check SDS/MSDS documentation for each reagent and follow standard laboratory PPE, handling, and waste-disposal procedures.
