Tools for the bench and for choosing a supplier

A solution-prep calculator for lyophilised vials, and the checklist behind every Vialwise score. Both run entirely in your browser, with no sign-up.

  • Free to use
  • Working shown in full
  • Nothing you type is stored or sent

  • Lab calculator

    Reconstitution calculator

    Enter the mass in a vial and the diluent you add. Get the concentration, the volume that holds a set mass, and how many aliquots the vial makes, with every step of the working shown.

    • Concentration in mg/mL and µg/µL
    • Volume per aliquot in µL and mL
    • Whole aliquots, and what’s left over
    • Reverse mode: diluent for a target concentration

  • Checklist

    Supplier checklist

    Work through the 16 checks we score, on any supplier’s website. The total updates as you answer, using exactly the weights behind our rankings.

    • 16 checks in 4 groups, 100 points
    • Where to look for each item, including the ABR
    • Group-by-group breakdown as you go
    • Reset and start again for the next supplier

Everything on Vialwise concerns research-grade material sold for laboratory and analytical use only. It is not a registered medicine, is not supplied for human or veterinary use, and nothing here is medical advice.

How they’re built

Plain arithmetic and published rules

Nothing in either tool is a black box. Both show their working, and neither needs anything from you but numbers and answers.

  • Arithmetic, not advice

    The calculator works with mass, volume and concentration. It has no knowledge of any particular compound and makes no recommendations.

  • One rubric, everywhere

    The checklist imports the scoring rules behind every Vialwise ranking, so a total you work out yourself is calculated exactly the way ours are.

  • Private by design

    Both tools run in your browser. There is no account, and nothing you type is saved or sent to us.
