Needles are precision-engineered sterile instruments essential for a broad range of laboratory applications requiring precise fluid handling, sample injection, or tissue penetration. This category includes hypodermic needles, syringe needles, blunt-fill needles, biopsy needles, and dispensing needles—each designed for specific tasks in molecular biology, cell culture, pharmacology, veterinary science, and clinical diagnostics.
Needles are categorized by gauge (diameter), length, bevel style, and material composition. Standard gauges range from 16G (large-bore) to 30G+ (ultra-fine), with each size selected based on viscosity, sample volume, and target tissue. Smaller gauges minimize tissue trauma and are ideal for delicate cell culture manipulations, while larger gauges are used for viscous fluids, blood collection, or large-volume transfer.
Laboratory needles are manufactured from high-grade stainless steel to resist corrosion, ensure sharpness, and maintain sterility. Features such as safety shields, Luer-lock compatibility, and ultra-thin-wall designs enhance usability and reduce contamination risk. Blunt-fill needles are widely used in pharmaceutical compounding and sterile liquid handling, where sharp tips are not required but precision is critical.
Common applications include intramuscular and subcutaneous injections in animal research, aseptic reagent transfer, sampling from sealed vials, PCR reaction setup, vaccine preparation, and high-precision drug delivery. Needles are frequently used alongside syringes, liquid handlers, and automated dispensing systems in routine and high-throughput labs.
Wasteless Bio offers unused surplus needles from reputable medical and laboratory suppliers, providing full transparency on gauge, length, bevel type, sterility, and packaging. All items meet ISO and FDA standards for laboratory and medical use. By sourcing needles through Wasteless Bio, research teams can significantly lower consumable costs, reduce procurement lead times, and support a more sustainable approach to lab operations—without sacrificing precision or safety.
