Product Description
LIGHT LABS is proud to offer the CELLTREAT 50mL Serological Pipet (Cat # 229030B) — a premium, sterile, individually wrapped standard serological pipet featuring an anti-drip tip specifically engineered for accurate delivery of large liquid volumes. The anti-drip tip is a key design feature exclusive to CELLTREAT's 25mL and 50mL serological pipet formats — the two sizes where accurate delivery is most challenging due to the increased weight of the liquid column and the greater momentum of large-volume transfers. The anti-drip tip precisely controls liquid flow at the pipet tip, preventing unwanted post-transfer dripping that can reduce delivery accuracy and contaminate adjacent wells, vessels, or work surfaces.
Manufactured to ASTM Standard Specification E-934 using high-quality polystyrene, the 229030B features bi-directional (positive and negative) graduations printed in dark, bold, easy-to-read ink — including a printed indicator arrow for quickly locating negative graduations when using a pipet controller. Orange color-coded stripes on both the pipet body and the individual paper/plastic wrapper enable instant 50mL volume identification across the bench or biosafety cabinet. A premium barrier plug prevents contamination of the pipet controller. The resealable bag packaging — 25 pipets per bag — keeps unused pipets clean and accessible between uses. Every case is printed with the lot number for quality traceability.
Note: For the maximum stability and drip-free performance of CELLTREAT's patented 2-tier step plug design, see the Wobble-not™ 50mL Serological Pipet (229094B). LIGHT LABS is your trusted source for CELLTREAT laboratory consumables.
