Polypropylene Culture Test Tube Globe Scientific 5ml 3000g 1000

Description

Product Overview

Globe Scientific’s 5ml polypropylene culture test tube is engineered to meet the rigorous demands of modern biological research, microbiology, and clinical diagnostics. Constructed from high‑grade polypropylene, the tube provides exceptional chemical resistance, ensuring that aggressive reagents, solvents, and buffers do not degrade the container. The dimensions of 12mm diameter by 75mm length conform to standard laboratory racks, allowing seamless integration with existing equipment such as incubators, shakers, and storage cabinets. Each tube is designed to withstand centrifugal forces up to 3000 times the force of gravity (3000 g), making it suitable for high‑speed centrifugation steps without risk of breakage or leakage. Autoclavable at temperatures up to 121 °C, the tubes can be sterilized repeatedly, supporting reusable workflows and reducing waste. The clear, natural‑colored polymer offers easy visual inspection of sample volume and color, while the smooth interior surface minimizes sample adhesion, promoting accurate measurement and transfer. With a capacity of 5 ml, the tube balances sufficient volume for most assays with minimal sample consumption, an important factor when working with precious or limited specimens. The product is supplied in a bulk pack of 1,000 tubes, delivering cost‑effective inventory management for high‑throughput laboratories that require consistent, reliable supplies.

Usage

These polypropylene culture test tubes excel in a wide range of laboratory environments, from academic research labs investigating cell culture and microbial growth to industrial quality‑control facilities performing sterility testing and product validation. Their robust construction makes them ideal for routine procedures such as inoculation, sub‑culturing, and sample storage, as well as more demanding applications like high‑speed centrifugation, heat‑based sterilization, and long‑term incubation at temperatures ranging from 4 °C to 37 °C. The tubes are compatible with standard pipettes, serological pipettes, and automated liquid handling systems, enabling precise dispensing of reagents and samples. Because the material is inert, the tubes are suitable for use with a broad spectrum of chemicals, including acids, bases, organic solvents, and enzymatic solutions, without risk of leaching or contamination. Researchers working with sensitive cell lines appreciate the autoclavable nature of the tubes, which ensures a sterile environment for each experiment. The 5 ml volume is particularly advantageous for assays that require multiple replicates or serial dilutions, as it reduces the need for frequent tube changes and minimizes sample waste. In high‑throughput settings, the bulk packaging of 1,000 tubes streamlines inventory control, allowing laboratories to maintain a ready supply without frequent reordering.

FAQ

Can these tubes be used for both bacterial and mammalian cell culture?

Yes, the polypropylene material is inert and compatible with a wide range of biological samples, including bacterial cultures, yeast, and mammalian cell lines. The tubes can withstand the temperature ranges typically required for incubation (4 °C to 37 °C) and are safe for use with common culture media, antibiotics, and supplements. Their autoclavable nature also allows you to sterilize them before initiating a new culture, ensuring a contaminant‑free environment for both prokaryotic and eukaryotic applications.

What centrifuge speeds are safe for these tubes?

The tubes are specifically designed to endure centrifugal forces up to 3000 g. This rating covers most standard laboratory centrifuges used for pelleting cells, precipitating proteins, or separating supernatants. When operating near the maximum limit, it is recommended to balance tubes precisely and to use appropriate rotor adapters to prevent imbalance. Exceeding the 3000 g threshold may increase the risk of tube deformation or leakage, so adhering to the specified limit ensures optimal performance and safety.

How many autoclave cycles can the tubes withstand?

Globe Scientific has validated the tubes for at least 20 autoclave cycles at 121 °C for 15 minutes each, without observable loss of structural integrity or changes in dimensional accuracy. This durability makes them suitable for repeated sterilization in busy laboratory environments where reusable consumables are preferred. After each cycle, inspect the tubes for any signs of warping or discoloration; under normal conditions, the tubes should remain clear and functional throughout their intended lifespan.

Is there technical support available if I encounter issues?

Globe Scientific provides dedicated technical support staffed by experienced laboratory professionals. Whether you need assistance with product specifications, troubleshooting unexpected performance, or guidance on best practices for storage and handling, the support team is reachable via phone, email, or online chat. They can also supply documentation such as material safety data sheets (MSDS) and detailed usage guidelines to help you integrate the tubes seamlessly into your workflow.
