smal l diameter, high precision tubes

Capillary tubing breakthrough for high-pressure applications

tolerances and burr-free end conditions are critical. HandyTube’s engineers will work to provide custom solutions, including bending and fabrication. HandyTube’s USD capillary tubing with Chromat ID™ was designed to increase measurement reproducibility, batch- to-batch. The smooth bore Chromat ID offered on USD capillaries limits Newtonian flow through the sample loop, resulting in improved peak shape and resolution. The small, tightly controlled ID coupled with the smooth bore ensures uniformity, sample-to- sample and unit-to-unit.

HandyTube can supply tubing that can withstand over 36,000 psi (2,500 bar).

With recent developments in food safety and environmental regulation, laboratory technicians are being pushed to obtain greater results in less time. Applications such as high performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) now require smaller samples to be processed at higher speeds for quicker analysis. HandyTube’s ultra-small diameter (USD™) capillary tubing products are precisely engineered for these applications, with an outside diameter less than 1.59mm (0.0625"). Demand for these engineered products has steadily increased as the desire for smaller assemblies and high-pressure equipment has become necessary.

HandyTube claims that production of these products is less of a challenge with its USD capillary tubing, which can measure 0.076mm (0.003"). USD tubing can be produced in extremely long coils – a capability that can translate to reduced set-up time. For example, a 2,000ft-long coil can be loaded onto a machine and run continuously, eliminating coil-to- coil downtime that exists when shorter coils are processed. USD capillary tubing can also be provided in straight lengths. HandyTube uses precision cutting equipment to produce parts for unique applications where tight

Redrawn precision tubes Tecnofar SpA was founded in 1974 in Delebio, Italy, as family-run company specialising in manufacturing stainless steel and nickel alloy tubes. Experimentation and research,

welding and heat treatment processes of product ranges OD 5-77mm and WT 0.35-2.6mm for austenitic series; and OD 5-77mm and WT 0.56-1.95mm for ferritic series.

The company’s quality system achieved international standard ISO 9001:2008, accredited by Italcert, and is structured in such a way as to ensure continuous improvement of products and customer service.

together with the development of new technologies, has made Tecnofar an advanced company in this field. The company has two production units, located in Delebio and Gordona, covering a total surface area of around 10,000m 2 . Tecnofar produces redrawn precision tubes, both in bar and coil form, using the TIG welding process. The company offers a modern, well-equipped department for tube cutting, and is able to produce completely burr-free cut pieces measuring just a few millimetres in length. The company can supply stainless steel tubes ranging from 0.3 to 20mm OD, and from 0.1 to 2mm wall thickness, for precision tubes, while for welded tubes the maximum diameter available is 76mm, with wall thickness up to 3.5mm. Tecnofar uses stainless steels provided and guaranteed by leading steel mills, and offers products in line with the strictest production controls.
