Product Description
Overheating the last few hundred microliters of an extract can drive off the very compounds you are trying to measure. This concentrator tube protects the sample with an insulated air space around its constricted tip, buffering it from bath temperature as concentration nears completion.
This listing is for Kimble catalog number 570071-1025: Concentrator Tube, 10 mL. Made from borosilicate glass 3.3 with a 19/22 joint, the jacketed tube comes in 10, 15 and 25 mL capacities with 0.1 mL graduations in the 0-1 mL range and 1 mL graduations above. Secure it to a Kuderna-Danish assembly with a 675300 polyacetal clamp, sold separately. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
