Product Description
LIGHT LABS is proud to offer the CELLTREAT Wobble-not™ 5mL Serological Pipet (Cat # 229091B) — the most stable, drip-free, and easy-to-insert 5mL serological pipet available, featuring the same 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 — one at each tier — dramatically increasing stability, virtually eliminating dripping, and reducing the insertion force required to seat the pipet securely.
The 229091B features bi-directional (positive and negative) graduated markings at 0.1 mL increments for precise small-volume dispensing. Ultra-clear markings and blue color-coded stripes on both the pipet body and individual paper/plastic wrapper enable instant 5mL 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. The 5mL format is ideal for routine cell culture media additions, reagent transfers, and molecular biology liquid handling where sub-5mL volumes are frequently required. 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
- Bi-directional (positive and negative) graduations at 0.1 mL increments — precise small-volume dispensing with printed indicator arrow for quickly locating negative graduations
- Blue color-coded stripes on pipet body and individual wrapper for instant 5mL 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; 50 pipets per resealable bag; 4 bags per case (200 pipets/case)
- Fisher Scientific Catalog No. 50-202-116
