Product Description
LIGHT LABS is proud to offer the CELLTREAT Wobble-not™ 10mL Serological Pipet (Cat # 229092B) — the most widely used serological pipet size in the laboratory, now with CELLTREAT's patented Wobble-not™ 2-tier step design that outperforms every traditional 10mL serological pipet on the market. The 10mL serological pipet is the everyday workhorse of cell culture and molecular biology labs — used for media additions, reagent transfers, and routine liquid handling more frequently than any other pipet size — making stability, drip-free performance, and ease of insertion more important for this format than any other.
Traditional 10mL serological pipets have a straight cylindrical plug end that creates only a single zone of contact with the pipet controller nozzle — allowing wobbling and dripping that compromises accuracy and increases contamination risk, particularly in high-throughput workflows where hundreds of transfers may be performed per session. 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 result is less fatigue, fewer drips, and more accurate transfers — every time.
The 229092B features bi-directional (positive and negative) graduated markings at 0.2mL increments for precise volume delivery. Ultra-clear markings and orange color-coded stripes on both the pipet body and individual paper/plastic wrapper enable instant 10mL volume identification. A porous polypropylene filter 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
- 10mL format — the most widely used serological pipet size in cell culture and molecular biology; the everyday workhorse of the laboratory
- Patented 2-tier step design at plug end — creates two zones of contact with the pipet controller nozzle; maximum stability, no wobbling, drip-free performance
- Requires less insertion force than traditional 10mL serological pipets — no jamming; less operator fatigue during high-throughput workflows
- The only 10mL serological pipet with two zones of controller nozzle contact — more accurate, less risk of contamination
- Bi-directional (positive and negative) graduations at 0.2mL increments — bold, easy-to-read ink with printed indicator arrow for locating negative graduations
- Orange color-coded stripes on pipet body and individual wrapper — instant 10mL volume identification
- Porous polypropylene filter plug — prevents contamination of pipet controller; two zones of secure airtight contact with nozzle
- Compatible with any pipet controller — Drummond, Eppendorf, Integra, CELLTREAT ali-Q Edge, and all major brands
