Microcentrifuge Tube 2.0 ml 500 ExtraGene PP DNase/RNase Free

Description

Product Overview

The ExtraGene 2.0 ml microcentrifuge tube is engineered for demanding molecular biology workflows where sample integrity and reproducibility are paramount. Each tube is fabricated from high‑grade polypropylene, a material known for its chemical resistance, low binding properties, and ability to withstand extreme centrifugal forces up to 18,000 RCF without deformation. The tube features precise graduation marks at 0.5 ml, 1.0 ml, 1.5 ml, and a full‑volume indicator at 2.0 ml, allowing researchers to quickly verify sample volumes without the need for additional measuring devices. A flat top and a dedicated side‑wall labeling area provide ample space for clear, permanent sample identification, reducing the risk of mix‑ups during high‑throughput processing.

Designed to be DNase‑ and RNase‑free, these tubes eliminate the risk of nucleic‑acid degradation, a critical requirement for PCR, qPCR, sequencing library preparation, and other sensitive downstream applications. The tubes are supplied in a convenient bulk bag of 500 units, ensuring that laboratories have a reliable inventory for routine experiments, large‑scale projects, and emergency stockpiles. The packaging dimensions of 9 × 7 × 5 inches and a lightweight 1.3 lb total weight make storage and handling straightforward, while the robust construction resists cracking or leakage during repeated heating cycles, such as those encountered in thermal cyclers or water baths.

ExtraGene, a reputable manufacturer in the life‑science supplies market, guarantees that each batch meets stringent quality control standards. The product carries the model number TUBE‑200‑MIX and has been available since February 2017, reflecting a proven track record of reliability and user satisfaction. With a competitive price point of $99.00 for 500 tubes, the offering delivers excellent value for academic, clinical, and industrial laboratories seeking consistent performance without compromising on cost.

Usage

These 2.0 ml tubes are ideal for a broad spectrum of laboratory techniques, including nucleic‑acid extraction, enzyme reactions, sample storage, and short‑term incubation. Their DNase/RNase‑free status makes them especially suitable for RNA work, where contamination can dramatically affect results. Researchers frequently employ these tubes in high‑throughput settings such as 96‑well plate formats, where the flat top facilitates seamless integration with automated liquid‑handling systems and barcode scanners.

In addition to standard centrifugation, the tubes perform reliably under rapid temperature changes, allowing them to be used in heat‑shock protocols, PCR thermal cycling, and freeze‑thaw cycles without compromising structural integrity. The clear polypropylene material provides excellent visual inspection of sample clarity, color changes, or precipitation, enabling quick troubleshooting during assay development. The side labeling area is compatible with permanent markers, laser etching, or adhesive labels, ensuring that sample identification remains legible throughout the experimental workflow.

Because the tubes are supplied in a bulk bag, they are well‑suited for large‑scale projects such as genome‑wide association studies, high‑throughput screening campaigns, and biobanking initiatives where thousands of aliquots must be processed and stored reliably. The tubes also meet the needs of teaching laboratories, where durability and ease of use are essential for student training and repeatable results.

FAQ

Are these tubes compatible with standard microcentrifuge rotors?

Yes, the 2.0 ml size conforms to the dimensions required by most bench‑top microcentrifuge rotors, allowing seamless integration into existing laboratory equipment.

Can the tubes be autoclaved for sterilization?

While the tubes are supplied sterile and DNase/RNase‑free, they can safely withstand autoclave cycles at 121 °C for up to 30 minutes without deformation, making them suitable for additional sterilization if required.

What is the maximum temperature these tubes can endure?

The polypropylene material remains stable up to approximately 150 °C, enabling use in most heating applications, including PCR thermal cycling and water‑bath incubations.

Do the tubes come with a guarantee or warranty?

ExtraGene offers a limited warranty that covers manufacturing defects. If a batch fails quality testing, we will replace the affected units at no cost to the customer.

How should the tubes be stored for long‑term stability?

Store the tubes in a cool, dry environment away from direct sunlight. The bulk bag provides protection from moisture and dust, preserving the DNase/RNase‑free condition for years.
