Robert M. Rioux and Taslima A. Zaman, Pennsylvania State University, Pennsylvania, PA Users are responsible for the proper disposal of the waste generated during their work. Improper waste disposal may severely endanger public health and/or the environment. The handling of hazardous waste must be regulated from the moment of generation until its disposal at its offsite final destination facility. A waste management system must be devised before work begins on any laboratory activity. Users...

Disposing of accounts receivable refers to the process of removing unpaid invoices from a company’s books, either by selling them or writing them off. This is a critical part of managing working capital and ensuring accurate financial reporting.One common approach is factoring, where a company sells its receivables to a third party at a discount. The buyer, known as a factor, provides immediate cash but keeps a portion of the receivable as a fee. While this results in a financial loss, it...

Methods for a wide-scale central nervous system gene delivery in the rat are covered. In this example, the purpose is to mimic a disease that affects the entire spinal cord. The widespread transduction can be used to deliver a therapeutic protein to the CNS from a one-time, peripheral administration.
FAQs
The tip creates a temporary liquid-contact interface with the pipette. When the operator presses and releases the plunger, air displacement draws liquid into the tip and then expels it at the selected volume. This mechanism makes the fit between tip and pipette, along with controlled plunger operation, important for consistent aspiration and dispensing.
Replacing the tip between samples limits liquid carryover from one sample to the next. This practice is especially important when preparing reagents, handling cultures, or performing serial dilutions, where transferred material could alter a later sample. Fresh Disposable Tips therefore support sterile technique and help preserve the reliability of quantitative results.
A Disposable Tip keeps the liquid-contact portion separate from the pipette itself. Because the tip forms the temporary interface used for aspiration and dispensing, it helps protect the pipette from liquid exposure during routine transfers. This separation is useful when handling biological samples and contributes to a cleaner, more controlled workflow.
Reproducibility depends on maintaining consistent liquid transfer while preventing contamination and sample carryover. Using a fresh tip between samples addresses contamination risk, while the plunger-driven air-displacement process determines how liquid is aspirated and dispensed. Applying these practices consistently helps quantitative experiments produce more reliable and repeatable measurements.
A typical workflow connects the tip to the pipette, uses plunger movement to aspirate the intended liquid, and then dispenses that liquid into the receiving vessel. After handling one sample, the tip is replaced before the next sample or transfer. This sequence supports reagent preparation, culture handling, and other controlled liquid-transfer tasks.
In molecular biology, Disposable Tips are used when preparing reagents, performing serial dilutions, and loading samples for assays such as PCR. These workflows often require accurate transfers and careful separation between samples. Changing tips helps reduce carryover, supporting the reliability of reactions and the interpretation of quantitative experimental results.
