Sorbent Tubes for Gerstel TDUs

Gerstel is a well respected, family owned scientific instrument manufacturer that began in Germany the late 60’s. Gerstel focuses on sample preparation and sample introduction instruments and offer a few different Thermal Desorption instruments to be used alone or in conjunction with other Gerstel sample prep/introduction products. The Gerstel TDU, Gerstel TDS 3, TDS G and Gerstel Twister instruments use Sorbent Tubes in two sizes: 6mm x 60mm and 6mm x 7”.

The Camsco Difference in TDU Sorbent Tubes.

Camsco is the most innovative Sorbent Tube maker. Both glass and stainless steel TDU tubes have barcodes, unique serial numbers and flow direction arrows are included sainless steel and fritless glass tubes. To ensure sample and testing accuracy, we inert coat all internal metal parts as part of our standard manufacturing process. The inert coated wire mesh and G-clips are less likely to introduce active sites and interfere with your analysis.

Camsco uses only the best raw materials. Camsco steel TDU Sorbent Tubes are made using Surgical Grade 316L stainless steel. Our borosilicate-33 glass tube stock is German Schott-Duran we never use Simax glass.

Camsco has the most practical experience building Sorbent Tubes (2 Million tubes) and the most experienced tube fabricators many with more than 10,000 hours of specialized tube manufacturing expertise.

Camsco's vertically integrated manufacturing facility is unmatched meaning we don’t rely on 3rd parties for any part of the tube manufacturing process.

Camsco is the largest Sorbent tube manufacturing company producing more Sorbent Tubes than all other TDU tube suppliers combined generating huge economies of scale.

COGNI™ System

Barcode, serial number, and circumferential bands come standard as part of the COGNI System. The identification marks are permanently embedded on the tubes offering an inherent advantage over other identification methods.

Custom Features – Stainless Steel

Custom options include inert coatings and conditioned tubes can be shipped with compression fittings. Cap options include compression caps (brass, steel and PTFE) and analytical caps (brass and PTFE) for conditioned tubes.

Custom Features – Borosilicate Glass

Options include fused glass frits, without glass frits and quartz wool. Tube manufacturing includes centerless grinding, ground ends, chamfers, lapping, polishing and annealing.

Capping Options

Compression caps, analytical caps and passive sampling caps are available. Please refer to the Capping Options page for more information.

If compression caps are ordered with conditioned tubes, Camsco guarantees that each cap is torqued to optimal tightness.
