Allied Telesis 6870 manual Cleaning the Vials

Page 19

The impactor will have to be separated from the sample and can be handled with gloved fingers, a strong magnet, tongs, or pliers. Tools without a good gripping surface are likely to slip off the impactor.

If some condensation on a cold sample is unacceptable, you can either wait for the sample vial to warm up before opening and emptying it, or open and empty a chilled vial in a glove box filled with dry nitrogen gas, argon, etc.

Small amounts of sample usually adhere to the vial’s impactor, end plugs, and plastic cylinder. Brushing or scraping these surfaces of the vial can often recover this fraction of the sample. Again, speed is important to minimize condensation and other effects of warming.

If it is necessary to recover 100% of the sample, let the vial warm up and add some water or other liquid that will not affect the polycarbonate (see 6.34, Cleaning the vial). Shake the vial, empty it onto some filter paper, and rinse again if necessary to recover all the sample.

6.34 Cleaning the Vials

Freezer/Mill vials may be superficially cleaned quickly and easily by placing them under running hot water. If the vial is cold a coating of ice will form on the steel parts, but will melt quickly as the water runs.

The plastic center cylinders for all vials, and the Poly-Vial end plugs and impactor capsules, are made of polycarbonate. While this polymer is very tough at low temperatures, it is sensitive to alcohol, acetone, and other organic solvents, and should be cleaned only with soap and water. A mild bleach solution will control organic contamination. Polycarbonate can be autoclaved, but this will weaken it.

Before re-using polycarbonate parts, always inspect them for cracks or other damage. They may last for dozens or hundreds of samples, but as soon as they begin to crack they should be discarded.

If sample adheres to the steel end plugs and impactor, they can be cleaned with water and soap or detergent, or with organic solvents. If they must be disinfected or cleaned of any organic residue, they can be washed with bleach or chemical cleaners or autoclaved, but should always be dried immediately after use. The steel parts in the 6751, 6801, and 6881 vials are made from 440C Stainless Steel, a so-called magnetic stainless steel, which is corrosion-resistant but will rust if left in contact with water. Surgical-grade stainless steel, which is truly rustproof, is nonmagnetic and cannot be used for Freezer/Mill end-plugs and impactor.

The steel parts of the chromium-free 6771, 6871, and 6883 vials can also be washed, disinfected, autoclaved, etc., but chromium-free steel is not rust-resistant and must always be dried immediately after washing. Store Cr-Free Vial parts in a sealed bag with a desiccant.

Rust on steel Freezer/Mill parts can be removed by scrubbing them with steel wool or an abrasive cleanser. If rusting persists, store the parts in a sealed bag with a desiccant.

6870 specifications

The Allied Telesis 6870 is a robust Layer 3 Ethernet switch designed for high-performance networking in enterprise environments. Incorporating advanced features and technologies, it serves as a vital component in managing complex network infrastructures, ensuring seamless connectivity, reliability, and enhanced performance.

One of the standout characteristics of the 6870 is its support for a high number of Gigabit Ethernet ports. With multiple SFP and SFP+ ports, the switch allows for flexibility in connecting various devices, while also facilitating the use of different physical media. This capability is crucial for organizations that demand versatile connection options, particularly when managing diverse networking equipment.

The switch is equipped with advanced Layer 3 routing capabilities, allowing it to perform IP routing functions in addition to standard Ethernet switching. Suitable for traffic management, the switch supports protocols such as OSPF, RIP, and static routing, enabling efficient and intelligent path selection in larger networks. This functionality is essential for optimizing bandwidth usage and maintaining an efficient data flow throughout the network.

Another highlight of the Allied Telesis 6870 is its support for VLANs (Virtual Local Area Networks). VLANs enable network segmentation, improving security and performance by isolating different segments of traffic. This capability is further enhanced by the switch's support for advanced features like Ingress/Egress Rate Limiting and Quality of Service (QoS). These features allow network administrators to prioritize critical applications and ensure that bandwidth is allocated effectively.

The switch also incorporates the innovative Allied Telesis Autonomous Management Framework (AMF), which simplifies device management and network configuration. With AMF, administrators can manage multiple switches as a single logical entity, reducing operational complexity and minimizing downtime. This technology supports zero-touch provisioning, enabling rapid deployment and configuration of network devices.

Security is another key aspect of the 6870, with features such as Access Control Lists (ACLs) and IEEE 802.1X port-based authentication. These measures help protect the network from unauthorized access and ensure that only authenticated devices can connect to the network.

In summary, the Allied Telesis 6870 is a versatile and powerful switch that meets the demands of modern enterprise networks. With its comprehensive feature set, including high-performance routing, VLAN support, and advanced management capabilities, it offers a reliable solution for organizations seeking to optimize their network infrastructure. Whether for deploying new services or managing existing traffic, the 6870 stands out as a formidable choice for network administrators.
