Specification Brand : Gardco BulletPoint1 : Set of 12 bubble tubes BulletPoint2 : U-Z6 standards BulletPoint3 : Two empty tubes BulletPoint4 : Our bubble tubes can be recertified to NIST traceable standards BulletPoint5 : 4056 centistokes, 40.2 seconds ItemName : Gardco VI-VG-9200/C Bubble Viscometer Tube Set, Certified U-Z6 Standards ItemTypeKeyword : science-lab-viscometers Manufacturer : Gardco NumberOfItems : 1 PartNumber : VI-VG-9200/C ProductDescription : Gardco bubble viscometers are used to quickly determine kinematic viscosity of known liquids such as resins and varnishes. The time required for an air buble to rise is directly proportional to the viscosity of the liquid - the faster the bubble rises, the lower the viscosity. Gardco bubble viscometers come in lettered tubes A5 through Z10 in four different tube sets covering viscosity ranges from 0.05 to 1,000 stokes. ProductSiteLaunchDate : 2019-11-09T23:47:08.322Z
