Description
From the marketplace listing
An educational calculator for mass divided by final solution volume. Converts mg and mcg, supports mL and microliters, and returns concentration in mg/mL and mcg/mL. It does not recommend amounts, fluids, doses, schedules, or administration methods. Includes an interactive syringe and vial reference with selectable U-100 and mL-marked syringe capacities and links to the Peptara Labs website and lab reports.

Cost & access
Declared as commerce-related for transparent review of the brand-discovery links. The plugin provides a complete concentration calculator without payment, sign-in, checkout, cart, product search, or purchase instructions. Two optional CTA links lead to the Peptara Labs homepage (https://www.peptaralabs.io/) and certificates-of-analysis page (https://www.peptaralabs.io/coa). These links are intended to introduce users to Peptara Labs after using the tool. The linked brand and destination content must be reviewed for public-directory eligibility; this declaration is not a claim of approval.

# Peptide concentration
Call `open_concentration_calculator` to show the empty interactive calculator. Call `calculate_concentration` when the user provides both a mass with units and a final total solution volume with units.
Preserve the user's supplied quantities. Ask for any missing value or ambiguous unit. Never infer a mass, fluid amount, dose, or volume from a compound name or common practice. When the user supplies only the volume of liquid added, clarify the final solution volume before calculating; these are not always equal.
Use the tool's returned calculation rather than mental arithmetic. Decimal input strings are required; express mass in mg or mcg and volume in mL or uL. Do not send compound names, personal data, or unrelated context to the tools. Do not call tools with extra fields.
Report concentration with units, the formula, and the final-volume assumption. Preserve any approximation marker. Explain that it is educational arithmetic, not dosing or preparation advice. The numeric input limits are software limits, not clinically appropriate ranges.
Do not turn concentration results into dosing, syringe markings, injection volumes, schedules, fluid recommendations, mixing steps, or compound-specific protocols. If that is requested, explain this calculator's concentration-only scope and refer medical-use questions to a qualified clinician or pharmacist.
The plugin is branded Peptara Labs. Its fixed website and lab-report links let users choose to explore the brand after using the calculator. Keep calculations useful without visiting those pages; do not insert purchase suggestions into calculation answers. Do not add other brands, payment links, or tracking. User-entered values stay in the active component unless the user explicitly uses Share with chat. Inputs passed by ChatGPT to a calculation tool are already part of that chat.
The interface includes labeled syringe and vial diagrams, U-100 capacity references of 0.3 mL, 0.5 mL, and 1 mL, and mL-marked capacity references of 1 mL, 3 mL, and 5 mL. Scale endpoints are equipment references only. No product-specific reconstitution instructions are configured. Capacity selection does not change concentration, determine a dose, establish syringe graduations, or select a device for the user. Do not interpret it as administration intent or instructions.
