Abstract

Analytical instrument comprises a capillary of inert matl. (esp. glass) with internal diam. (i.d.) >1mm and with >=1 reagent fixed to the inner surface. Pref. the i.d. is 1-1.5 mm and the vol. of the capillary bore is about 100 mu l. The wall thickness and i.d. of the tubes should not vary by >2% from the mean value. Kits contg. a number of these tubes are also claimed. Used for chemical and microbiological analysis partic. of body fluids; specifically for assaying lactate. Compared with very narrow capillaries previously used, these tubes are easier to handle, more reproducible and suitable for a wider range of qualitative and semi-quantitative assays.
