Transfer Pipet Globe Scientific 139050-S20 Extra Long Sterile 23mL

Description

Product Overview

The Globe Scientific 139050 S20 Transfer Pipet is engineered to meet the demanding standards of modern laboratory environments where precision, sterility, and ergonomic design are essential. Constructed from high‑quality, autoclavable polypropylene, this pipet provides a chemically resistant barrier that safeguards both the sample and the user from contamination. Its extra‑long 300 mm shaft allows users to reach deep vessels, flasks, and reservoirs without compromising control, while the 23 mL capacity ensures sufficient volume for a wide range of applications, from routine buffer transfers to more specialized reagent handling. The pipet’s tip is manufactured with a smooth, tapered geometry that promotes consistent flow and minimizes the risk of air bubbles, delivering reliable performance across repeated cycles. Each unit is supplied sterile, eliminating the need for additional sterilization steps and reducing the risk of introducing microbial contaminants into sensitive experiments. The design incorporates a graduated, easy‑to‑read scale etched directly onto the shaft, enabling quick visual verification of volume without the need for auxiliary measuring devices. With a total length of 300 mm and a lightweight yet robust construction weighing just over two pounds per pack, the pipet balances durability with user comfort, making it suitable for extended use during high‑throughput workflows. The pack of 100 units is packaged in a compact box measuring 15.98 × 7.6 × 7.48 inches, facilitating efficient inventory management and easy distribution to multiple workstations within a laboratory. Whether employed in academic research, pharmaceutical development, or quality‑control laboratories, the Globe Scientific Transfer Pipet delivers the consistency and reliability required for reproducible results.

In addition to its core functional attributes, the Globe Scientific Transfer Pipet conforms to ISO 13485 standards for medical device manufacturing, ensuring that each component meets rigorous quality control criteria. The polypropylene material is BPA‑free and resistant to a broad spectrum of solvents, acids, and bases commonly encountered in biochemical protocols, allowing the pipet to be used with aggressive reagents without degradation. The sterile packaging utilizes a barrier film that maintains aseptic conditions until the point of use, and the individual units are individually sealed to prevent cross‑contamination. The pipet’s ergonomic grip is designed with a contoured surface that reduces hand fatigue during repetitive pipetting tasks, while the smooth barrel surface minimizes the accumulation of residues, simplifying cleaning procedures. For laboratories that require traceability, each pack includes a batch number and manufacturing date printed on the exterior, facilitating compliance with Good Laboratory Practice (GLP) documentation requirements. The combination of these thoughtful design elements makes the 139050 S20 model a versatile tool that integrates seamlessly into existing liquid‑handling workflows.

Usage

The 139050 S20 Transfer Pipet is ideally suited for a variety of laboratory settings where accurate and sterile liquid transfer is paramount. Its extra‑long shaft enables users to reach into deep conical flasks, graduated cylinders, and reaction vessels without the need to tilt or reposition the container, preserving sample integrity and reducing the risk of spillage. The sterile tip ensures that each transfer remains free from microbial contamination, a critical factor in cell culture, microbiology, and molecular biology workflows.

In cell culture laboratories, the pipet is frequently used to dispense media, supplements, and reagents into multi‑well plates and culture dishes while maintaining a closed, aseptic environment. Molecular biologists appreciate the precise volume control when preparing PCR master mixes, enzyme reactions, and nucleic acid purification steps, where even minor deviations can affect downstream results. Quality‑control technicians in pharmaceutical and biotech firms rely on the pipet for consistent sampling of solvents, buffers, and standards during validation and stability testing, benefiting from its reproducible performance across repeated uses.

The robust construction also makes the pipet suitable for field‑based environmental testing labs, where users may need to transfer water or soil extracts from large containers into analytical vials. Its compatibility with a wide range of chemicals allows it to be employed in organic synthesis labs for the safe handling of corrosive acids or volatile solvents, provided appropriate safety protocols are followed. Because the pipet is supplied sterile and individually sealed, it can be stocked in bulk and accessed as needed without compromising the sterility of the remaining inventory.

Overall, the 139050 S20 serves researchers, technicians, and engineers who demand reliable, contamination‑free liquid handling across diverse experimental contexts, from high‑throughput screening to routine bench work.

FAQ

Can the pipet be autoclaved for reuse?

Yes, the pipet is made from autoclavable polypropylene and can be sterilized in a standard autoclave cycle without compromising its structural integrity or performance.

Is the pipet compatible with viscous liquids?

The smooth, tapered tip design facilitates the transfer of low‑ to medium‑viscosity liquids. For highly viscous substances, a slower dispensing rate is recommended to maintain accuracy.

What is the recommended storage condition for the sterile packs?

Store the sealed packs in a cool, dry environment away from direct sunlight. The barrier film maintains sterility for up to 12 months when unopened.

Does the pipet meet any regulatory standards?

Yes, the product complies with ISO 13485 for medical device manufacturing and is manufactured under GMP‑compliant conditions, ensuring high quality and traceability.

Can I order custom packaging or labeling?

Globe Scientific offers custom packaging options for bulk orders, including private labeling and batch‑specific documentation to meet specific regulatory or branding requirements.
