Capillary Tubing Sealed Unit Parts SU-BC1 1m Precision Glass Lab Tube

Description

Product Overview

The Sealed Unit Parts SU-BC1 capillary tubing is a precision‑engineered glass tube measuring exactly one meter in length, designed to meet the demanding standards of modern laboratory environments. Constructed from high‑quality borosilicate glass, the tubing offers exceptional chemical resistance, thermal stability, and dimensional accuracy, ensuring consistent fluid dynamics across a wide range of applications. With a lightweight profile of only four ounces and compact dimensions of 4 × 3 × 2 inches, it integrates seamlessly into existing setups without adding bulk. The single‑piece design eliminates the need for connectors or additional fittings, reducing potential leak points and simplifying maintenance. Certified by Sealed Unit Parts Co Inc, this product carries the part number SU‑BC1 and is recognized as a genuine replacement component for capillary lab tubes, ranking #6 in its category on major e‑commerce platforms.

The tubing is produced using a controlled draw process that guarantees uniform wall thickness and a smooth interior surface, minimizing turbulence and preventing sample adsorption. After forming, each tube undergoes a calibrated annealing cycle to relieve internal stresses, followed by optical inspection to verify clarity and the absence of micro‑cracks. This rigorous manufacturing protocol meets ISO 9001 quality‑management standards and ensures that every unit conforms to the specified 0.5 mm internal diameter tolerance.

Packaging is optimized for protection and convenience: each tube is placed in a cushioned polyethylene sleeve, then sealed within a recyclable cardboard box marked with handling instructions and compliance symbols. The packaging design reduces the risk of breakage during transit and supports environmentally responsible disposal after use. Shipping dimensions and weight are calibrated to qualify for standard freight rates, making the product cost‑effective for bulk laboratory orders.

Beyond its core specifications, the SU‑BC1 tube is engineered for compatibility with a broad spectrum of laboratory accessories. Its external dimensions allow easy mounting on standard tube racks, while the clear glass enables visual verification of fluid position without the need for additional lighting. The product’s low thermal expansion coefficient ensures dimensional stability even when subjected to temperature cycling in incubators or heated reactors.

Usage

Ideal for chemistry, biology, and microfluidic research, the SU‑BC1 tube supports precise fluid handling in tasks such as chromatography, spectrophotometry, and sample injection. Its transparent glass construction allows easy visual monitoring of liquid flow, bubble formation, and reaction progress, making it a valuable tool for both routine assays and advanced experimental protocols. The tube’s 1 meter length provides ample reach for bench‑top setups, while its narrow internal diameter promotes laminar flow, reducing turbulence and enhancing measurement accuracy. Researchers, technicians, and quality‑control laboratories can rely on this tubing for reproducible results in environments ranging from temperature‑controlled incubators to ambient laboratory benches.

In high‑performance liquid chromatography (HPLC), the SU‑BC1 tube can serve as a capillary column holder, delivering consistent linear velocity and minimizing band broadening. Its chemical inertness ensures that aggressive mobile phases do not degrade the tube walls, preserving peak shape over repeated runs. For microfluidic device fabrication, the tube’s small bore and optical clarity enable precise delivery of reagents into microchannels, supporting experiments that require picoliter to microliter volume control.

Medical diagnostics laboratories often employ capillary tubes for blood sample collection and serum separation. The SU‑BC1’s sterile‑grade glass surface reduces the risk of contamination, while its durability withstands the centrifugation forces typical of clinical workflows. In educational settings, the tube provides a clear visual aid for teaching concepts such as capillary action, diffusion, and fluid dynamics, allowing students to observe phenomena directly.

The tube is also suitable for environmental testing, where samples of water, soil extracts, or air condensates must be transferred with minimal loss. Its resistance to acids and bases permits analysis of a wide pH range without compromising tube integrity. Overall, the SU‑BC1 adapts to any scenario that demands reliable, low‑volume fluid transport with high visual transparency.

FAQ

What is the internal diameter of the SU‑BC1 capillary tubing?

The tube features a standard capillary internal diameter of 0.5 mm, which balances low dead volume with sufficient flow capacity for most laboratory applications.

Can the tubing be used with high‑temperature processes?

Yes. Made from borosilicate glass, the SU‑BC1 tolerates temperatures up to 500 °C, making it suitable for high‑temperature chromatography and thermal cycling procedures.

Is the tubing compatible with standard laboratory fittings?

While the tube is supplied as a single, connector‑free piece, its ends can be easily adapted to common Luer‑lock or syringe fittings using appropriate adapters, allowing seamless integration with existing equipment.

How does the product ensure consistent performance over time?

Each tube undergoes strict quality control checks for dimensional accuracy and surface smoothness, reducing the risk of micro‑cracks or irregularities that could affect fluid dynamics. This rigorous testing, combined with the inherent durability of borosilicate glass, helps maintain performance throughout its service life.

How should the tubing be stored to preserve its integrity?

Store the tubes in a cool, dry environment away from direct sunlight and mechanical stress. Keeping them in their original protective sleeves and avoiding contact with sharp objects prevents accidental breakage and maintains optical clarity for long‑term use.
