Samco Transfer Pipette 3 ml Large Bulb 1000 Pipets

Samco 225 Graduated Transfer Pipette (3 ml Stem, Large Bulb)

The Samco 225 is a premium, high-capacity transfer pipette engineered for the rapid and safe movement of liquid samples in clinical, research, and industrial laboratories. Manufactured from high-clarity, low-density polyethylene (LDPE), these shatterproof one-piece pipettes eliminate the risk of broken glass and cross-contamination associated with traditional Pasteur pipettes. The unique "Large Bulb" design provides a powerful suction force, allowing for a total draw of approximately 3.5 ml in a single squeeze. With molded-in graduations up to 3 ml, the Samco 225 combines high-volume efficiency with the ability to perform rough volumetric measurements.

Technical Performance and Design

• High-Suction Large Bulb: The oversized bulb is designed to draw more fluid than the graduated stem capacity, ensuring that the 3 ml markings can be reached easily in a single aspiration cycle.

• Shatterproof LDPE Construction: Produced from medical-grade polyethylene that is inert to most biological fluids and common laboratory chemicals. The flexible material allows for easy access into narrow vessels and deep containers.

• Molded Graduations: Features clear, easy-to-read markings at 0.5 ml increments up to 3.0 ml, facilitating consistent aliquoting and reagent additions during routine laboratory procedures.

• Uniform Tip Geometry: Engineered to deliver consistent drop sizes, which is essential for qualitative testing, slide preparation, and pH adjustments.

Key Benefits & Applications

• Clinical Diagnostics: Widely used for transferring blood, serum, and urine samples from primary collection tubes to secondary analysis vessels.

• Rapid Reagent Transfer: The high-capacity bulb makes this the ideal "workhorse" pipette for filling reservoirs, adding buffers, and large-scale sample dilutions.

• Safety & Disposal: As a disposable, one-piece unit, it eliminates the need for rubber bulbs and glass cleaning, significantly reducing the risk of exposure to infectious agents or hazardous chemicals.

• Surface Tension Management: The low-affinity surface of the LDPE minimizes sample "clinging," ensuring maximum fluid delivery and reducing waste of expensive reagents.
