Product Description
LIGHT LABS is proud to offer the CELLTREAT 50mL Serological Pipet in the Double Case Economy Format (Cat # 229031B) — providing 200 individually wrapped sterile serological pipets per case at the best per-pipet price in the CELLTREAT 50mL individually wrapped serological pipet lineup. The double case format saves up to 65% on shipping costs, reduces order frequency, and minimizes cardboard waste compared to ordering two separate standard cases — making the 229031B the preferred choice for high-volume labs, core facilities, and production environments that use 50mL serological pipets on a frequent, routine basis.
Like the standard 229030B, the 229031B features an anti-drip tip specifically engineered for accurate delivery of large liquid volumes — precisely controlling liquid flow at the pipet tip to prevent unwanted post-transfer dripping that can reduce delivery accuracy and contaminate adjacent vessels or work surfaces. This is particularly important for the 50mL format where the larger liquid column creates greater momentum that can cause dripping in traditional serological pipets. Bi-directional (positive and negative) graduations at 1mL increments are printed in bold, easy-to-read ink with a printed indicator arrow for quickly locating negative graduations. Orange color-coded stripes on both the pipet body and individual paper/plastic wrapper enable instant 50mL volume identification. Every case is printed with the lot number for quality traceability. LIGHT LABS is your trusted source for CELLTREAT laboratory consumables.
