Description

Product Overview

Four Es presents the PTS200-Z-US series of 200 µL yellow universal pipette tips, engineered to meet the rigorous demands of modern scientific laboratories. Each tip is manufactured from high‑quality, non‑pyrogenic polymer that is DNAse and RNAse free, ensuring that samples remain uncontaminated throughout the handling process. The soft conical design creates a reliable seal with the pipette barrel, delivering exceptional accuracy and repeatability for volumes as low as 0.5 µL up to the full 200 µL capacity. The product dimensions of the packaging are 9.33 × 8.78 × 3.39 inches, with an item weight of 11.3 ounces, making storage and transport convenient for busy lab environments. Produced by Four Es, a trusted manufacturer in the industrial and scientific sector, the tips carry the model number PTS200-Z-US and are listed under ASIN B085C4S9HT. Since their launch on March 2 2020, they have achieved a Best Sellers Rank of #70,670 in Industrial & Scientific and #14 in Universal Pipette Tips, reflecting strong adoption by researchers worldwide.

Usage

These 200 µL pipette tips are ideal for a broad range of applications, including PCR setup, qPCR, next‑generation sequencing library preparation, ELISA, cell culture media transfers, and chemical assay dispensing. Their yellow coloration provides a visual cue that helps prevent cross‑contamination between different reagent types. The tips are fully compatible with most major pipette brands such as Gilson, Biohit, Thermo, and LabSystems, allowing seamless integration into existing workflows. Researchers in molecular biology, biochemistry, genetics, and environmental testing can rely on the consistent performance of these tips for both routine and high‑throughput protocols. Autoclavability enables the tips to be sterilized without degrading their structural integrity, making them suitable for sterile environments and repeated use in clean‑room settings. The ergonomic design also reduces the risk of repetitive strain injuries (RSI) for laboratory personnel who perform frequent pipetting tasks.
