CM Scientific are European distributors for Polymicro Technologies LLC. As specialists in the manufacture of Flexible Fused Silica Capillary, Polymicro Technologies provide a complete range of high quality standard and speciality products which we are delighted to be able to supply to our European clients.
As the world leader in fused silica capillary for the Gas Chromatography (GC), Liquid Chromatography (LC) and Capillary Electrophesis (CE) markets, Polymicro's capillary products are used by many of the world's leading OEM's in their chromatography products.
CM Scientific provide a range of Polymicro Technologies products including flexible fused silica tubing and capillary assemblies which are used by various clients worldwide, including research establishments and leading commercial organisations for use in analytical chemistry applications.
This flexible fused silica capillary is used for a wide range of chromatography columns in applications including Gas Chromatography (GC), Capillary Electrophoresis (CE) and Capillary Liquid Chromatography (CLC or LC).
Fused silica tubing is used as the base material for producing capillary columns such as gas chromatography columns and liquid chromatography columns. Since its introduction in the early 1980's fused silica capillary has become the standard column material for nearly all gas chromatography column, liquid chromatography column and capillary electrophoresis column manufacturers.
Although flexible fused silica capillary tubing is now used over a broad range of applications, one of the first applications for capillary tubing was in the Gas Chromatography (GC) industry. The growth in the use of gas chromatography can be traced back to the development of fused silica capillary as the basis for nearly all gas chromatography columns. Since its first use in the late 70's, the range of capillary tubing internal diameters (ID) has grown, and specification tolerances have continually tightened to meet the exacting demands of the GC column manufacturing industry. Numerous Gas Chromatography column manufacturers offer a broad selection of columns used in the analysis of food products, pharmaceuticals, clinical samples, petroleum, and a variety of other applications.
Polymicro produces a wide range of capillary designed specifically for GC applications. Capillary with ID's ranging from 50µm up to 750µm are routinely used, with the majority of gas chromatography columns employing capillary between 180µm and 530µm. Two product lines are commonly used, these being the standard TSP and high temperature TSG.

Capillary Electrophesis (CE) is a separation method based on the differential migration rates of sample components within a capillary when an electrical field is applied to the capillary. Key features that make fused silica capillary tubing the CE column material of choice include:

Chromatographic techniques that employ a liquid mobile phase loosely fall into a category referred to as Liquid Chromatography (LC). Capillary fills two fundamental roles in LC applications, as connection lines and as liquid chromatography columns.
Liquid chromatography capillary diameters most commonly range from 50µm up to 500µm, with a variety of different designs available. Standard TSP products are commonly used with TSU products gaining interest for some monolithic columns.

CM Scientific provide the full range of Polymicro's standard fused silica tubing products including polyimide and UV transparent coatings. A large standard range of sizes are also available from 2µm to 700µm internal diameters.
Alternative buffer coatings and custom sizes are available, if you have a specific requirement please feel free to contact us and we will be happy to help.
Please feel free to browse our online store for full product details. Once you have decided which capillary product is right for you then you have a choice of which format you would like to purchase it in. Available formats include:
Bulk: The majority of capillary is supplied to the market in long, continuous lengths on polystyrene reels. Reel length is dependent on customer requirements but is generally 10-100m.
Pre-cut: Capillary is often pre-cut to customer specified dimensions. Different quality of end finishes are available.
Windowed Capillaries: CM Scientific also supplies precision windowed capillary tubing. Parts are supplied with the polyimide coating removed over a defined length at a specified distance from one end of the capillary section. This provides an optical quality window that has excellent mechanical properties as well.
Additional ranges including square bore and thick wall flexible fused silica capillary are also available.
