Terms
By using Meniscus Mark, you accept that it is a free educational browser model with a deliberately narrow scientific scope and no guarantee of suitability for real laboratory work.
Educational scope
The game models a 50 mL buret, 0.1 mL printed divisions and a transparent aqueous concave meniscus. It demonstrates downward-increasing readings, hundredth-place estimation and final-minus-initial delivered volume. It does not model every liquid, buret, calibration class, optical condition or procedure.
Not a substitute for instruction or safety controls
Do not use an on-screen answer as authorization to handle chemicals or equipment. Meniscus Mark does not replace a teacher, supervisor, laboratory manual, risk assessment, safety data sheet, personal protective equipment, inspection, calibration, real glassware practice or emergency procedure. Follow the requirements that apply to your actual setting.
No metrology or certification claim
The SVG is not calibrated equipment. Pixels, browser zoom and display scaling are not volume standards. A correct game answer shows agreement with the generated exercise only. The site provides no grade, certificate, competency assessment, professional advice or accreditation.
Availability and warranty
The site is provided as available without warranties of uninterrupted access, error-free operation, fitness for a particular course or accuracy beyond the tested exercise rules. Features, questions and copy may change when reproducible issues are corrected. Keep independent records if a teacher asks you to document practice.
Original work and acceptable use
Do not present the site, original art, code, brand or explanations as another provider’s official product. Do not use the site to distribute malware, probe unrelated systems or publish private information. Links to the public contact route are provided for good-faith reports.
