Valves for Analysis and Research

Asco Numatics offer specialist valves for analytical research. Asco's valves are optimised for the handling of corrosive liquids and gases, and can be applied in a broad range of laboratory and industrial applications.

Valves for Analytical Research

Asco's valves for analytical research are made from inert materials, that are resistant to damage from aggressive substances. They are designed for easy flushing, zero dead volume and low power usage - reducing the amount of heat transmitted to the fluid.

All Asco products are built to ensure that the fluid never makes contact with the valve's EM control systems. The valves are constructed for corrosive-resistant polyetherimide, or polyphenylene sulphide. A choice of seals are available ranging from silicone to ethylene propylene, styrene butadiene and fluoroelastomer, so the valves may be adapted for various temperatures and environments. The valves can be used in temperatures up to 100ºC with neutral gas, air, oil, water and various other fluids.

Valves for Biomedical Analysis

Miniaturisation and automation are becoming increasingly important for biological and medical research. Medical biology is driving the health care market in process optimisation and development. Valves and automation equipment are essential to this development across the big 5 biopharmaceutical sectors: biochemistry, immunochemistry, immunology, microbiology and haematology. Valves are also available for specific, medical applications.

Asco's portfolio of solenoid valves for biomedical analysis include:

• Miniature rocker type miniature solenoid valves with small dead volume designed to be installed in series, with laboratory or industrial type connections.
• Lever valves supporting a fast rate of flow and minimal heat transfer. These valves are also designed for both industrial and pharmaceutical applications and particularly simple to take apart and maintain.
• Low-powered diaphragm valves offering a rapid response and low dead volume.
• Low-powered tube pinch valves designed to be combined in series. These miniature solenoid valves are designed for contamination-free handling of ultra pure fluids.

Valves for Industry

Asco supply valves for many industry applications ranging from metering and regulation to monitoring, process control and an array of other purposes. These valves are used in environmental analysis and energy generation, and in the manufacture of pharmaceuticals, agriculture supplies, chemicals and cosmetics.

In addition to the rocker, lever, diaphragm and tube pinch valves listed above, Asco offer bellows type valves, designed specifically for the industrial handling of aggressive substances.

A common requirement for both the biomedical and industrial sectors is minimising exposure between the solenoid valve's mechanical parts, and the fluids passing through the valves. This serves to limit the amount of heat transmitted to the funds being processed. It also helps to prevent chemicals from being contaminated by the processing equipment, or equipment from being damaged by the aggressive substances that they contain.
