SECTION 2.0: 6870 FREEZER/MILL SPECIFICATIONS

Type of mill: cryogenic impact mill

Grinding mechanism: steel impactor driven by dual electromagnets

Coolant: liquid nitrogen

Weight (empty, without vial or coolant): approx. 44 lbs. (20 Kg)

Grinding Vials: one 6801 Large Vial, one Mid-Size Vial (6871, 6881, 6885), or one 6753 Microvial set, also one to four Small Vials (6751, 6751/52, 6761, 6771).

Typical Sample Capacity:

Small Vials: actual volume with impactor, approx. 25 ml. Typical sample weights: 2 grams for biological samples, 1 gram for polymers. Effective capacity for a given sample is determined by trials. Overfilling a vial greatly reduces its efficiency.

6753 Microvial Set: 100 - 500 mg per individual 6753V Microvial, depending on sample.

Mid-Size Vials have up to 5 times the sample capacity of Small Vials, and Large Vials about twice the sample capacity of Mid-Size Vials.

Actual performance of any vial/sample combination depends on sample properties, cooling time, grinding time, desired outcome, etc.

Typical liquid nitrogen consumption:

10-15 liters for initial cool-down and filling of the tub. 4-6 liters for each hour of operation

Actual LN consumption can vary.

Electrical specifications: CE Approved, available in 115V 60HZ or 230V 50HZ.

Cord: 115V 60HZ version, 3-prong grounded plug supplied. 230V 50HZ version, 2-prong European plug supplied.

Operator is responsible for supplying alternate line cord/plug if required.

Fuses: Two 5-amp slow-blow fuses in AC Input module. 25-amp slow-blow fuse on driver board

Dimensions: 20½ in. (52 cm) x 21½ in. (55 cm) x 18 in. (46 cm)

CE Compliance and Certification: The 6870 Freezer/Mill has been tested for compliance with CE Directives for Industrial, Scientific, and Medical Equipment Emission, and Generic Light Industrial Immunity.

Safety Features:

Lid Interlock prevents mill from running if lid is not latched shut. Liquid nitrogen sensor shuts down mill if liquid nitrogen level is too low.

NOTE: Liquid nitrogen level should be visually checked during extended runs as well as before every run. The Freezer/Mill warranty does not cover damage to the coil caused by operating the mill with little or no liquid nitrogen.

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.
