Strong-Tough Rubber Suction Bulb

Constructed from natural rubber known for balanced strength and flexibility, each bulb delivers reliable performance under regular lab use. Physical specs: ~8 cm long, ~4 cm bulb diameter, ~25 g weight. Holds up to ~20 ml per full compression cycle. Material retains elasticity after hundreds of squeezes and cleans easily with warm water or ethanol wipe-downs. Functionally designed for manual liquid aspiration: user compresses bulb fully, places tip in solution, releases to generate negative pressure and draw liquid upward. Multiple cycles ensure effective removal of residual concentrate — particularly useful in pipette cleaning and ear irrigation protocols. Endorsed for daily use in demanding environments — including metallurgical labs processing ore slurries, plant pathology units handling fungal cultures, and hygiene-focused food microbiology labs where non-porous, non-shedding tools are preferred.
