NEXA LAB TOOLS

Precision you can follow.

Use your own laboratory quantities. Explore the volume, understand each conversion and check the limits of the measuring scale.

NEXA LAB TOOLS

Clear numbers. Every step.

Calculate concentration and sample volume.
See the units, the scale and the limits.

Single-compound mass entries. HCG potency units, blends and diluents retain their product-page tools.

Your laboratory sample

Illustrative numbers only. Enter quantities from your laboratory protocol.

Active compound only, excluding fillers and other ingredients.

mL

Use the final measured volume. The volume of added diluent can differ.

A user-entered laboratory amount, not a recommended dose.

Measuring capacity · U-100 scale
Material cost optional +

Enter the cost of this vial plus diluent actually used. No prices are assumed.

What the calculation assumes: known active mass, complete dissolution, uniform concentration and the final measured solution volume. Counts are theoretical and exclude dead volume, transfer losses and instrument error. Displayed decimals are rounded for readability; inputs are not silently rounded to scale marks.

U-100 is a volume scale: 100 marks = 1 mL. These are not peptide potency units, pen clicks, or U-40/U-500 marks. U-100 calibration reference ↗

Laboratory arithmetic only. This tool does not determine a treatment dose or establish diluent suitability, sterility, stability or suitability for human or animal use.
