Specifications
The Eppendorf PCR Clean Microcentrifuge Tubes 1.5ML PK500 022363212 are designed for precision and purity in molecular biology workflows. Each tube boasts a 1.5 ml capacity, the standard volume for many PCR and micro-sample applications. They are constructed from highest purity, low adhesion polypropylene, a material known for its chemical resistance and minimal sample binding.
Key features include a flat top for easy labeling and a secure seal, crucial for preventing evaporation and contamination during thermal cycling or centrifugation. Volume graduations are clearly marked, aiding in accurate dispensing, and the etched marking surfaces allow for permanent labeling with pens or markers. The tubes are rated to withstand up to 25,000 g, making them suitable for a wide range of centrifugation speeds commonly employed in research labs.
The designation “PCR Clean” signifies that these tubes are certified free from human DNA, DNase, RNase, and PCR inhibitors. This is achieved through fully automated production and packaging within a cleanroom environment, with independent laboratory testing and certification for each batch. This rigorous quality control ensures that experiments dependent on the integrity of nucleic acids are not compromised by external biological contaminants. The pack contains 500 tubes, a generous quantity that offers good value for busy research settings.
Performance & Functionality
The primary function of the Eppendorf PCR Clean Microcentrifuge Tubes 1.5ML PK500 022363212 is to reliably contain and protect biological samples during various laboratory procedures. In this regard, they perform exceptionally well. The low-adhesion polypropylene surface consistently delivers near-quantitative recovery of precious samples, minimizing loss due to sticking.
The secure sealing mechanism of the Safe-Lock lid is a standout strength, effectively preventing accidental spills or evaporation, even during prolonged incubation or high-temperature PCR cycles. I have personally experienced issues with less robust lids popping open during centrifugation, leading to sample loss and potential biohazard situations, making this feature a critical advantage. The main weakness, inherent to all microcentrifuge tubes, is their single-use nature; while excellent for preventing contamination, it does contribute to plastic waste.
Compared to generic laboratory tubes, these units exceed expectations in terms of purity and sealing integrity. While slightly more expensive per unit than uncertified alternatives, the cost is justified by the reduced risk of experimental failure due to contamination or sample loss, especially for sensitive molecular biology assays. They meet and largely exceed the demands of standard laboratory workflows.
Design & Ergonomics
The design of the Eppendorf PCR Clean Microcentrifuge Tubes 1.5ML PK500 022363212 is a masterclass in practical ergonomics for a laboratory setting. The polypropylene barrel is translucent, allowing for easy visualization of the sample volume, while the etched marking surface provides a reliable area for sample identification. The flat-hinged lid is a significant ergonomic improvement over older designs, enabling one-handed opening and closing.
This one-handed operation is a subtle but crucial benefit when you’re juggling pipettes, reagents, and other lab equipment. The lid design also ensures it stays securely open when needed and snaps shut with a definitive click. The tubes are designed to be easy to open and close, even after repeated use or when hands might be gloved or slightly damp. There is no discernible learning curve; the design is intuitive for anyone familiar with basic laboratory consumables.
Durability & Maintenance
As disposable laboratory consumables, the concept of “durability” for the Eppendorf PCR Clean Microcentrifuge Tubes 1.5ML PK500 022363212 relates more to their resilience during use rather than long-term physical integrity. They are engineered for single-use applications, meaning their lifespan is tied to the specific experiment. During their intended use, they exhibit excellent resilience, withstanding significant forces and temperature fluctuations.
Maintenance is non-applicable as they are designed to be discarded after use, which is a key aspect of their “clean” designation. This avoids the risk of carryover contamination often associated with reusable glassware or less rigorously cleaned plasticware. While there are no specific maintenance tips, one must ensure proper disposal according to laboratory biohazard waste protocols. Potential failure points, though rare with this brand, would typically involve the hinge or seal if subjected to extreme forces beyond their specifications.
Accessories and Customization Options
The Eppendorf PCR Clean Microcentrifuge Tubes 1.5ML PK500 022363212 are primarily standalone consumables, and as such, do not typically come with accessories or extensive customization options in the traditional sense. The primary “accessory” is the 500-pack bulk quantity, which is a practical offering for laboratories. These tubes are designed to work seamlessly with standard microcentrifuge rotors and heat blocks.
While not directly customizable, their compatibility with common laboratory equipment is a key functional aspect. If one were to consider “customization,” it would involve the choice of marking pen or label applied to the etched marking surface. For highly specialized applications, different tube types (e.g., conical bottom, skirted, or specific volumes) exist within the broader Eppendorf product line, but for standard molecular biology, this 1.5 ml PCR Clean model serves as a versatile benchmark.
