Glass Capillary Tube Set Karter Scientific 200 Borosilicate Red & Blue

Description

Product Overview

The Glass Capillary Tube Set from Karter Scientific is engineered for laboratories that demand precision, reliability, and consistency in fluid handling. Each tube is fabricated from high‑grade borosilicate glass, a material celebrated for its superior thermal stability, chemical resistance, and clarity, ensuring that users can observe fluid movement without distortion. The set includes 200 tubes, evenly divided into 100 vibrant red tubes and 100 crisp blue tubes, providing visual differentiation for multiple sample streams or experimental conditions. Every tube measures 75 mm in length, with an inner diameter ranging from 1.1 mm to 1.2 mm and an outer diameter of 1.5 mm to 1.6 mm, dimensions that balance capillary action with ease of handling. The uniformity of these dimensions supports reproducible results in applications such as hematology, chromatography, micro‑fluidic device testing, and educational demonstrations. The packaging is compact, with dimensions of 6.81 × 2.44 × 1.57 inches and a lightweight of 2.08 ounces, making storage and transport straightforward for busy lab environments. Designed to meet the rigorous standards of modern scientific research, this capillary tube set delivers both functional performance and visual convenience, allowing technicians to quickly identify sample types by color while maintaining the integrity of delicate analyses.

Usage

These capillary tubes excel in a variety of laboratory settings, from clinical diagnostics to research and development. In hematology labs, the red‑colored tubes are frequently employed for blood collection, enabling easy visual confirmation of sample type and reducing the risk of cross‑contamination. The blue tubes serve equally well for plasma or serum separation, providing a clear visual cue for different processing steps. In micro‑fluidic research, the precise inner diameter facilitates controlled capillary flow, essential for experiments that investigate fluid dynamics at the microscale. The tubes are also suitable for chromatography applications, where consistent capillary dimensions ensure uniform migration rates and reliable separation of analytes. Educational institutions benefit from the color‑coded design, allowing students to distinguish between reagents or experimental groups during hands‑on training. Because the glass is chemically inert, the tubes can be used with a broad spectrum of solvents, acids, and bases without risk of degradation, making them a versatile tool for chemical synthesis, titration, and sample preparation. The 75 mm length provides enough volume for most standard assays while remaining short enough for easy handling with standard pipettes and tube holders.

Why Choose Us

Karter Scientific has built a reputation for delivering laboratory consumables that combine rigorous quality control with thoughtful design. Each capillary tube in this set undergoes a multi‑stage inspection process, including visual examination for glass imperfections, dimensional verification using calibrated micrometers, and pressure testing to confirm structural integrity. This meticulous approach guarantees that every tube meets the exacting standards required for high‑precision work. The use of borosilicate glass not only provides exceptional durability but also ensures that the tubes can withstand repeated heating and cooling cycles, a common requirement in protocols that involve temperature‑dependent reactions. Moreover, the color‑coded system reduces the cognitive load on technicians, allowing them to focus on experimental outcomes rather than tracking sample identities. Karter Scientific also offers responsive customer support, with a dedicated technical assistance team ready to address any questions regarding product compatibility, usage tips, or troubleshooting. In addition, the company provides a straightforward replacement policy for any defective items, reinforcing confidence in the reliability of the purchase. By choosing this capillary tube set, laboratories gain a dependable, high‑performance tool that aligns with both regulatory compliance and day‑to‑day operational efficiency.

FAQ

Can these capillary tubes be autoclaved?

Yes, the borosilicate glass construction tolerates standard autoclave cycles (121 °C for 15‑30 minutes) without cracking or deformation, making them suitable for sterilization before use.

What is the maximum volume each tube can hold?

Given the inner diameter of 1.1‑1.2 mm and a length of 75 mm, each tube can accommodate approximately 100‑120 µL of liquid, which is ideal for most micro‑scale assays.

Are the tubes compatible with standard tube racks?

Yes, the outer diameter of 1.5‑1.6 mm aligns with common laboratory tube rack specifications, allowing secure placement and easy retrieval during routine workflows.

How should I dispose of used capillary tubes?

Used glass capillary tubes should be collected in a designated sharps container and disposed of according to your institution’s hazardous waste protocols to ensure safety.

Do the red and blue tubes have different chemical properties?

No, the color difference is purely for visual identification; both red and blue tubes are made from the same high‑quality borosilicate glass and share identical performance characteristics.
