Kimble 73500-650 N-51A Borosilicate 1mL Culture Tube, Rim Top, 1000pcs

Description

Product Overview

The Kimble 73500-650 N-51A culture tube is engineered from high‑quality borosilicate glass that delivers exceptional chemical resistance and optical clarity. Each tube holds a precise 1 mL volume, making it ideal for a wide range of laboratory applications, from microbiological cultures to analytical chemistry assays. The rim top design provides a secure, leak‑free seal while allowing easy insertion and removal of samples, reducing the risk of contamination during handling. The tubes are manufactured to comply with ASTM Specification E438, Type I, Class B requirements, ensuring uniform wall thickness, consistent dimensions, and reliable performance across batches. Dimensions of the tube are optimized for bench‑top workflows, with a compact footprint that fits standard incubators, shakers, and storage racks. The clear glass construction enables straightforward visual inspection of culture growth, precipitation, or color changes without the need for additional lighting or equipment. Each tube is individually inspected for defects, guaranteeing that researchers receive a product that meets rigorous quality standards.

Usage

These culture tubes are suited for a variety of laboratory environments, including academic research labs, industrial quality‑control facilities, and clinical diagnostic settings. The 1 mL capacity is perfect for small‑scale inoculations, enzyme reactions, and sample preservation. The rim top allows for the use of standard caps or sealing films, providing flexibility for both short‑term experiments and long‑term storage. Because the glass is resistant to sodium leaching, the tubes maintain sample integrity even when exposed to aggressive reagents or high‑temperature sterilization processes such as autoclaving. Users can confidently employ the tubes in aerobic or anaerobic cultures, as the clear glass permits easy monitoring of gas production and turbidity. The tubes are also compatible with common laboratory equipment, including vortex mixers, centrifuges, and spectrophotometers, enabling seamless integration into existing workflows. For high‑throughput applications, the trays of 1000 tubes streamline inventory management and reduce the time spent searching for individual units.
