Product Description
LIGHT LABS is proud to offer the CELLTREAT Wobble-not™ 50mL Serological Pipet (Cat # 229094B) — the most stable, drip-free, and easy-to-insert 50mL serological pipet available, featuring a patented innovative 2-tier step design at the plug end that sets Wobble-not™ pipets apart from every other serological pipet on the market. Traditional serological pipets have a straight cylindrical plug end that creates only a single zone of contact with the pipet controller nozzle — allowing the pipet to wobble, drip, and require more force to insert. The Wobble-not™ patented 2-tier step design creates two distinct zones of contact with the controller nozzle — one at each tier — dramatically increasing stability, virtually eliminating dripping, and reducing the insertion force required to seat the pipet securely.
The result is a serological pipet that performs more consistently and comfortably than any traditional design — particularly valuable for the larger 50mL format where stability and secure seating in the controller are even more critical. The 229094B features bi-directional (positive and negative) graduated markings including negative graduations down to -10mL — a unique feature of CELLTREAT's 25mL and 50mL pipets that allows researchers to draw more than the nominal volume when needed. Ultra-clear markings and color-coded orange stripes on both the pipet body and the individual paper/plastic wrapper enable instant volume identification across the bench or biosafety cabinet. A premium polymer fiber barrier plug prevents contamination of the pipet controller. Manufactured to ASTM Standard Specification E-934 with ±2% accuracy at full volume. LIGHT LABS is your trusted source for CELLTREAT laboratory consumables.
KEY FEATURES
- Patented 2-tier step design at plug end — creates two zones of contact with the pipet controller nozzle vs. one zone for traditional straight cylindrical plug ends; dramatically increases stability and reduces wobbling and dripping
- Requires less insertion force than traditional serological pipets — easier, more comfortable pipetting especially during high-throughput workflows
- The only serological pipet with two zones of contact in the pipet controller nozzle — maximum stability and drip-free performance guaranteed
- Negative graduations to -10mL — unique feature allowing researchers to draw more than 50mL when needed; bi-directional (positive and negative) graduation markings
- Ultra-clear bi-directional graduations in bold, easy-to-read ink — printed indicator arrow for quickly locating negative graduations
- Color-coded orange stripes on pipet body and individual wrapper for instant 50mL volume identification
- Premium polymer fiber barrier plug — prevents contamination of pipet controller; creates secure, airtight seal
- Compatible with any pipet controller — Drummond, Eppendorf, Integra, CELLTREAT, and all major brands
- Manufactured to ASTM Standard Specification for Serological Pipets E-934
- Accuracy: ±2% at full volume
- Certified RNase-free, DNase-free, and nonpyrogenic
- Sterile — gamma irradiated
- Individually wrapped in paper/plastic wrappers; 25 pipets per resealable bag; 4 bags per case (100 pipets/case)
- Fisher Scientific Catalog No. 50-202-119
