Core Capability86 / 100 — 8 Categories

Functional Suitability
Buffer library expanded to 7 buffers (PBS, RIPA, TAE, HEPES, Tris-HCl pH 7.4, Tris-HCl pH 8.0, MOPS); custom recipe calculation now documented
11 / 12
92%
Reliability
Missing buffer type now offers manual calculation fallback; volume defaults to 500 mL with explicit assumption; script failure fallback present

Key Strengths

  • Embedded molecular weight reference table eliminates a common source of calculation errors
  • Buffer library expanded to 7 buffers (HEPES, Tris-HCl pH 7.4/8.0, MOPS added) covering most molecular biology workflows
  • Quick Verification section with expected PBS 1X 500 mL outputs enables rapid sanity checking after modifications
  • Custom recipe fallback using documented mass formula handles any unsupported buffer type
  • Common Pitfalls section covers the most dangerous lab errors (acid-to-water order, hydrate MW confusion)
