5ml Sterile Serological Pipettes SPL Blue Disposable 400 Pack

Description

Product Overview

Introducing the 5ml sterile serological pipettes from SPL, a reliable solution for laboratories that demand precision and contamination‑free liquid handling. Each pipette is manufactured from high‑quality polystyrene, guaranteeing chemical resistance and structural integrity even when used with viscous solutions. The blue coloration provides easy visual identification, while the clear, graduated markings allow quick volume verification. All 400 units are individually wrapped in sealed foil pouches, preserving sterility until the moment of use. The pipettes are DNase‑and RNase‑free, non‑pyrogenic, and non‑cytotoxic, meeting the stringent requirements of molecular biology, cell culture, and diagnostic assays. With an expiry date of December 2024, they are ready for immediate deployment in research, quality control, and routine laboratory workflows.

Usage

These 5ml serological pipettes are designed for a wide range of applications, from transferring culture media in cell culture plates to aliquoting reagents for PCR, ELISA, and immunoassays. Their ergonomic design reduces hand fatigue during repetitive pipetting, and the color‑coded system helps technicians select the correct volume at a glance, minimizing the risk of cross‑contamination. Because the pipettes are sterile and individually sealed, they are ideal for aseptic techniques such as inoculating flasks, preparing sterile dilutions, and handling sensitive biological samples. The pipettes perform reliably in both ambient laboratory environments and controlled biosafety cabinets, making them a versatile tool for academic, industrial, and clinical settings.

Technical Specifications

The pipettes have a nominal volume of 5 ml with an accuracy tolerance of ±0.02 ml, meeting ASTM standards for serological pipettes. Made from medical‑grade polystyrene, they exhibit a melt flow index that ensures smooth tip passage for low‑viscosity liquids while maintaining sufficient rigidity for viscous samples. Each pipette measures 16.54 × 15.75 × 9.84 mm and weighs approximately 0.09 g, allowing easy handling and minimal waste. The graduated scale is printed with ink that is resistant to solvents and does not leach into the sample, preserving assay integrity. The product is packaged in a master carton of 400 individually sealed units, with overall carton dimensions of 16.54 × 15.75 × 9.84 inches and a net weight of 19 lb, facilitating efficient storage and transport.

Packaging Details

Each pipette is sealed in a moisture‑proof foil pouch that guarantees sterility from the moment of manufacture until the point of use. The pouches are grouped into secondary cartons of 100 units, each labeled with batch number, manufacturing date, and expiration date (12‑2024). The outer master carton is printed with handling instructions, safety symbols, and a barcode for inventory management. This multi‑layer packaging strategy protects the pipettes from physical damage, humidity, and microbial contamination, ensuring that every unit arrives in pristine condition. For bulk orders, SPL can provide custom packaging configurations, including bulk shrink‑wrap or palletized shipments, to meet specific logistical requirements.

Compliance and Certifications

SPL Life Sciences adheres to stringent quality management systems, holding ISO 13485 certification for medical device manufacturing and ISO 9001 for general quality assurance. The pipettes are tested in accordance with USP sterility testing and comply with the European EN ISO 10993‑1 biocompatibility standard, confirming their suitability for cell culture and diagnostic applications. Endotoxin levels are verified to be below 0.05 EU/mL, and the products are free from detectable DNase and RNase activity, as confirmed by in‑house enzymatic assays. All materials are non‑pyrogenic and non‑cytotoxic, meeting the requirements of Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) environments.

Customer Testimonials

“The SPL 5 ml pipettes have become a staple in our molecular biology lab. Their consistency and sterility give us confidence in every experiment.” – Dr. A. Patel, Research Scientist.

“Having a reliable supplier that offers quick technical support has streamlined our procurement process dramatically.” – L. Chen, Quality Assurance Lead.

Best Practices for Use

To achieve optimal performance, allow the pipettes to equilibrate to room temperature before use, especially when handling temperature‑sensitive reagents. Avoid bending or applying excessive force to the tip, as this can compromise the graduated scale. When dispensing viscous liquids, pre‑wet the tip with a small volume of the same liquid to improve flow consistency. Store unopened pouches in a dry, temperature‑controlled environment (2‑25 °C) and discard any pipette that shows signs of moisture ingress or physical damage. For critical applications, verify volume accuracy with a calibrated balance before the first use.

FAQ

What does DNase‑free and RNase‑free mean for my experiments?

Being DNase‑free and RNase‑free means the pipettes contain no enzymes that could degrade DNA or RNA, protecting the integrity of nucleic acid samples during transfer and reducing the risk of false results in PCR, sequencing, or gene expression studies.

Can these pipettes be used with viscous liquids?

Yes, the polystyrene material and smooth interior surface allow easy handling of viscous solutions such as culture media, glycerol‑based buffers, or enzyme mixes without excessive resistance or tip blockage.

How should I store the pipettes to maintain sterility?

Keep the sealed foil pouches in a cool, dry place away from direct sunlight. Once opened, use the pipettes promptly and discard any that have been exposed to non‑sterile environments for extended periods.

Are the pipettes compatible with automated liquid handling systems?

The standard 5ml serological design is compatible with many manual and semi‑automated dispensers, but they are not specifically engineered for high‑throughput robotic pipetting platforms that require specialized tip geometry.
