The Solution To Oxygen Uptake & Evolution Uptake rates of 3 to 300 ul 0 2 / h r can be monitored with 1 % accuracy on YSI oxygen instruments, and the curves plotted on most 100 mv recorders. You can use extra small samples, as little as 1 ml of substrate, add inhibitors and activators easily, and complete most experiments in 5 to 15 minutes. Speed is up to 200 times faster, and sensitivity up to 25 times greater than manometric techniques.

These pipettes consist of short lengths of precision made capillary glass tubing, calibrated to contain a de finite volume f r o m end to end. They are accurate to w i t h i n 1 % or less and are so low in cost that you can afford to use them once and discard. While they are of great value in general micro-chemical applications, they are especially useful in the handling of dangerous material. No particular skill is needed to obtain accurate results. "MICROCAPS" are stocked in all sizes from One-half to 100 microliter capacity. Special sizes will be made to your order and are available on short notice. PRICES: All standard stock sizes from One-half to 100 microliters (Lambdas) - $5.00 per vial of 100, including bulb assembly. Quantity discount.
