Description
Product Overview
The 25mm Plastic In-Line Test Tube Rack is engineered to meet the rigorous demands of modern laboratory environments. Constructed from high‑grade white polypropylene, the rack offers exceptional chemical resistance, ensuring that it will not degrade when exposed to common solvents, acids, or bases used in scientific work. Its robust design supports six standard 25mm test tubes securely, while the integrated six drying pins provide a dedicated space for caps to dry, preventing cross‑contamination and maintaining sample integrity. The rack’s compact footprint—measuring just over ten inches in length—optimizes bench space, allowing researchers to maximize workflow efficiency without sacrificing organization. Each component is precision‑molded to exact tolerances, guaranteeing consistent tube alignment and stability during routine handling, centrifugation, or incubation processes. The white coloration not only contributes to a clean aesthetic but also enhances visibility of any residue or spills, facilitating quick clean‑up and compliance with laboratory safety protocols.
Beyond its functional attributes, the rack is designed with user convenience in mind. The smooth, rounded edges reduce the risk of accidental cuts or abrasions during handling, while the lightweight yet durable construction makes it easy to transport between workstations or storage locations. The product complies with ASTM standards for laboratory equipment, providing assurance of quality and performance. Its versatility extends to a variety of scientific disciplines, including chemistry, biology, microbiology, and clinical diagnostics, making it a universal solution for any setting that requires reliable tube organization and drying capabilities.

Usage
In a typical chemistry laboratory, the 25mm Plastic In-Line Test Tube Rack serves as an essential component for sample preparation and reaction monitoring. Researchers can arrange up to six test tubes in a single rack, allowing simultaneous observation of multiple reactions while maintaining a tidy workspace. The integrated drying pins are particularly valuable after washing procedures, as they keep caps elevated, facilitating rapid air drying and minimizing the chance of moisture re‑contamination. This feature is especially beneficial in microbiology labs where sterile conditions are paramount.
Clinical laboratories often employ the rack for handling patient samples, where precise organization and quick turnaround are critical. The rack’s clear white color aids technicians in quickly identifying any residual liquids or spills, promoting a safer working environment. Its compatibility with standard incubators and refrigerators ensures that samples can remain in the rack throughout various stages of analysis without the need for transfer to alternative containers.
Educational settings, such as university teaching labs, also benefit from the rack’s durability and ease of use. Students can learn proper sample handling techniques while the rack’s sturdy construction withstands frequent cleaning and repeated use throughout an academic term. The lightweight design allows instructors to quickly set up multiple workstations, enhancing the overall learning experience.
For field researchers conducting on‑site experiments, the rack’s compact size and lightweight nature make it an ideal portable solution. It can be easily packed alongside other essential equipment, ensuring that sample organization remains consistent even in remote locations. The drying pins are useful for drying caps after field‑collected specimens are rinsed, preserving sample integrity until they can be processed in a primary laboratory.

FAQ
What tube sizes are compatible with this rack?
The rack is specifically designed for standard 25mm (1‑inch) test tubes, which are commonly used in most laboratory protocols. It can also accommodate slightly smaller tubes, but optimal fit and stability are achieved with the intended size.
Can the rack be autoclaved for sterilization?
Yes, the polypropylene material tolerates standard autoclave cycles (121°C for 30 minutes) without deformation, allowing you to sterilize the rack alongside other lab equipment safely.
Is the rack suitable for use in refrigerated or frozen storage?
The rack’s material remains stable at typical laboratory refrigeration temperatures (2‑8°C) and can withstand short‑term exposure to freezer conditions. However, prolonged storage at extreme sub‑zero temperatures may affect the material’s flexibility.
How many drying pins are included and what are they for?
The rack includes six drying pins, each positioned to hold a test tube cap upright after washing. This arrangement promotes efficient air drying, helping to prevent moisture‑related contamination in subsequent experiments.
What warranty does Karter Scientific provide for this product?
Karter Scientific offers a one‑year limited warranty covering manufacturing defects. Should any issues arise, customers can contact our support team for replacement or repair options.
