Upchurch Scientific® seamless, precut, stainless steel tubing is designed to meet the exacting requirements of today's analyses.
- Autoclavable
- Sterilization: Gamma irradiation; ethylene oxide; thermal
A variety of precut lengths as well as longer lengths (1 to 7.6 m) of some sizes are available. Cutting the tubing disturbs and roughens the tubing's end surface, so it is recommended to use precut tubing lengths whenever possible. If custom lengths are required, it is suggested that the tubing is passivated after cutting. Stainless steel precut tubing is manufactured from 316 stainless steel except the 0.020'' outside diameter (Ext.Ø) size, which is manufactured from 304 series stainless steel.
Upchurch Scientific® stainless steel tubing is available in 1/16" and 1/8" outside diameter (Ext.Ø) sizes, as well as 0.020" and 1/32" OD capillary sizes. Many sizes feature a color-coded band for easy inside diameter (Int.Ø) identification. Rockwell Hardness (B) is maximum of 95.
Each machine-cut end is polished, deburred on the inside and outside edges, and then the entire tubing is passivated. Finally, reagent-grade isopropanol is flushed through each piece. The thorough preparation and cleaning procedure guarantees tubing that is truly ready-to-use, with flat, burr-free ends and a clean finish. This care is important in achieving zero-dead-volume connections and good chromatographic results. Additionally, this tubing can be sterilized by numerous methods; however, if the tubing needs to be autoclaved, the color-coded band (if present) should be removed beforehand.
