2.0 mL Screw Cap Microtube, Amber, Skirted, Graduated, Non-Ribbed — 500/bag

Product Description

The LIGHT LABS A-8053 is a 2.0 mL amber screw cap microtube — skirted base, graduated, non-ribbed, manufactured from high-clarity ultra-pure polypropylene meeting FDA 21 CFR 177.1520 and USP Class VI standards. The amber color provides light protection for photosensitive samples and reagents. Suitable for a wide range of temperatures from −196°C to +121°C — note: not suitable for immersion in liquid nitrogen. Rated to 20,000 × G. Ideal for boiling applications. Certified free of detectable RNase, DNase, DNA, and PCR inhibitors. 500 tubes per bag.

Amber Color — Light Protection for Photosensitive Samples The amber color of the A-8053 provides inherent protection against UV and visible light degradation — essential for samples, reagents, and standards that are sensitive to light exposure during storage and processing. For labs storing light-sensitive nucleic acids, fluorescent probes, photodegradable compounds, enzyme substrates, and other photosensitive materials in 2.0 mL screw cap format, the A-8053 amber microtube eliminates the need for foil wrapping or dark storage boxes while maintaining the sample in a standard screw cap tube format compatible with all standard microcentrifuge equipment.

Skirted Base — Maximum Stability for Standalone Use The skirted base of the A-8053 provides a broad, stable standing footprint — allowing the tube to stand upright independently on benchtops, in racks, and during pipetting operations without requiring a tube rack for support. For labs processing photosensitive samples that need to remain upright and covered during ambient light exposure, the skirted base of the A-8053 provides the tube stability required for safe, reliable bench-top operation without the risk of tip-over and sample loss.

Graduated — Volume Monitoring Without Removing the Cap The graduation markings on the A-8053 allow direct visual monitoring of fill volume through the amber tube wall — enabling accurate sample volume estimation during filling, storage, and processing without opening the tube and exposing the contents to air or light. For labs processing photosensitive samples where every cap removal represents an additional exposure risk, graduation markings that can be read through the closed amber tube are a practical operational advantage.

2.0 mL — The Standard Microcentrifuge Tube Volume The 2.0 mL capacity of the A-8053 is the largest standard microcentrifuge tube volume — providing the maximum working volume for sample storage, pelleting, extraction, and processing workflows in standard benchtop microcentrifuge equipment. At 2.0 mL, the A-8053 accommodates the full working volume of standard 1.5–2.0 mL microcentrifuge protocols while providing extra headspace for mixing and processing. The 2.0 mL format is compatible with all standard benchtop and high-speed microcentrifuges designed for 1.5 and 2.0 mL tube formats.

Non-Ribbed Exterior — Clean, Smooth Labeling Surface The non-ribbed exterior of the A-8053 provides a smooth outer tube wall — offering an uninterrupted surface for label application, marker writing, and barcode printing across the full exterior of the tube. For labs using printed adhesive labels or direct-print tube labeling systems, the non-ribbed smooth exterior ensures complete label adhesion without the air pockets and partial contact issues that can occur when labels are applied over ribbed tube surfaces.

20,000 × G Centrifugation Rating — High-Speed Compatible Rated to 20,000 × G. The robust polypropylene construction of the A-8053 withstands high-speed centrifugation at forces up to 20,000 × G — covering the full range of standard benchtop microcentrifuge speeds as well as high-speed centrifugation protocols for nucleic acid precipitation, protein pelleting, and bead-based sample processing that require forces well above the typical 13,000–14,000 × G maximum of standard laboratory microcentrifuges.

−196°C to +121°C Temperature Range — From Dry Ice to Autoclave Suitable for a wide range of temperatures — from −196°C to +121°C. Note: not suitable for immersion in liquid nitrogen. The A-8053 is compatible with the full range of standard laboratory temperature conditions from dry ice storage (−78°C), ultra-low freezer storage (−80°C), standard −20°C and −40°C freezer storage, refrigerated storage (+4°C), room temperature, to autoclave sterilization (+121°C). For labs that autoclave sample tubes as part of their sterile workflow, the A-8053 withstands standard autoclave cycles without deformation. The upper temperature rating also qualifies the A-8053 for boiling applications.

Ideal for Boiling Applications Ideal for boiling applications. The high-temperature rating of the A-8053 specifically qualifies it for boiling water bath incubation — a common step in nucleic acid denaturation, protein solubilization, and certain enzymatic inactivation protocols. For labs running boiling denaturation steps in their DNA extraction, RNA extraction, or protein analysis workflows, the A-8053 withstands the 100°C exposure of a boiling water bath without deforming or losing cap integrity.

Ultra-Pure Polypropylene — FDA 21 CFR 177.1520 and USP Class VI Manufactured from high-clarity, ultra-pure polypropylene meeting FDA 21 CFR 177.1520 and USP Class VI standards. The ultra-pure polypropylene formulation ensures that the A-8053 does not introduce chemical extractables, leachables, or biological contaminants into stored samples — critical for sensitive analytical, molecular biology, and clinical applications where trace contamination from tube materials would compromise results.

Certified RNase-Free, DNase-Free, DNA-Free, and PCR Inhibitor-Free Certified free of detectable RNase, DNase, DNA, and PCR inhibitors. The A-8053 meets molecular biology grade purity standards — qualified for nucleic acid storage, RNA extraction, DNA extraction, and PCR workflow applications where nuclease contamination or PCR inhibitors from tube materials would degrade samples or inhibit amplification.

SureSeal® Cap System — Secure, Leak-Resistant Closure The A-8053 features the SSI Bio SureSeal® screw cap system — engineered for secure, leak-resistant closure that maintains sample integrity during storage, transport, centrifugation, and temperature cycling. The screw cap format provides a more secure seal than snap-cap designs for applications involving extended storage, repeated freeze-thaw cycles, and high-centrifugation protocols where cap retention under force is required.
