Sigma Aldrich Fine Chemicals Biosciences Ketone Body Assay sufficie
Ketone bodies 3-hydroxybutyric acid (BOH) and acetoacetic acid (AcAc) are produced in the liver primarily from oxidation of fatty acids and are normally present at low concentrations in urine and blood. Increased ketone concentrations in the blood may lead to metabolic acidosis which has been associated with diabetes childhood hypoglycemia growth hormone deficiency alcohol or salicylate intoxication and inborn errors of metabolism.
Sigma Aldrich Fine Chemicals Biosciences WelchR ChemStarTM vacuum p1EA
ChemStar vacuum pumps are distinguished by having all five of the defining features needed for pumping corrosive gases..nbspHigh contamination tolerance large oil reservoir dilutes contaminants.nbspCorrosion resistant parts Viton(R) PTFE stainless steel nickel-plated or anodized parts.nbspReduced frictional wear runs at less than 580 rpm versus 1700 rpm for direct-drive pumps.nbspNitrogen purge standard degasses and cools pump oil reducing corrosion.nbspEasy attachment of accessories trap and oil mist eliminatorSupplied with 2 pin plugModel 1400N specificationsFree Air Displacement 0.9 cfm (25 L/min)Max. vacuum 1 x 10-4 torrOil capacity 0.62 qt (0.59 L)Tubing needed I.D. 7/16 in.Exhaust and intake thread type NW 16Pumping speed 580 rpmDim.
