Volume precision and range
Dispensers with broader volume ranges and finer adjustment increments cost more to manufacture. However, ±1% accuracy is ±1% accuracy regardless of price - paying 5x more doesn't make the volumes more precise. Standard ranges handle most lab applications effectively.
Chemical resistance materials
Specialized materials for aggressive chemicals increase costs modestly. However, borosilicate glass and PTFE components perform identically in $200 and $1000 dispensers - the material properties don't change based on brand name.
Construction and durability
Quality construction affects longevity, but premium pricing often reflects brand positioning rather than superior engineering. Well-designed economical dispensers deliver years of reliable service with basic maintenance.
Adjustment mechanisms
Digital volume displays and easy adjustment add modest cost but improve usability. However, premium brands charge dramatically more for essentially the same mechanisms - you're paying for marketing, not better engineering.
Brand premium and markup
This is where costs explode without functional benefit. Established premium brands charge 3-5x more for the same specifications, chemical compatibility, and dispensing accuracy. The volumes they deliver are identical - only the invoice differs.
Replacement parts availability
Some premium brands use proprietary parts that cost significantly more and limit your repair options. Dispensers with standard, accessible components provide better long-term value through affordable maintenance.
