Centrifuge Labware Tubes - Bottles - Adapters

Many factors influence the performance characteristics and lifespan of centrifuge consumables. This catalog has been compiled as a general guideline but, in no case, expresses absolute guarantee of the products under laboratory conditions. Due to the large number of different applications and techniques the single „perfect“ material for centrifuge tubes does not exist. A material may show excellent performance qualities in one application and then fail horribly in the next. Note: All centrifuge tubes should be tested prior to use. At the first sign of irregularities these tubes should be...

GmbH Laborgerate 1.1. Volume The volume of the tubes is determined by the size of the sample material, the rotor bores and the necessary adapters. Chemical Groups Temperature Range Note: For continuous low temperature applications PPCO resp. PA is the material of choice.

2.1. Materials for Tubes and Sealing Caps Glass Borex = B / Duran = D / HS = High-Speed Temperature range: B = 0 to + 250°C / D = 0 to + 200°C / HS = 0 to + 300°C Transparent glass tubes are available in Borex and Duran for low speed applications when clarity and good chemical tolerance is required. Glass tubes must be treated with care when removing pellets, washing and storing. Surface scratches and etchings will significantly reduce the life span of glass tubes. All glass tubes show a better tolerance to high temperatures than to low temperatures. However, strong acids and bases may...

GmbH Laborgerate 2. Material Description Temperature range: - 150° to + 121°C Polycarbonate is a transparent, rigid and non-pierceable material. It is compatible with neutral salt and dilute acid solutions but extremely sensitive to organic solvents, alcohols, oils, DMSO and alkaline solutions. Tubes and bottles are reusable, but care should be taken to avoid scratching the surface with glass rods and hard bristle brushes. Please use rubber coated spatulas and soft bristle brushes. -Important note for cleaning: Use only mild, non-alkaline detergents and wash them by hand. Repeated washing...

2. Material Description GmbH Laborgerate 2.4. Nomograph - Relative Centrifugal Force How to use the nomograph To determine the relative centrifugal force (RCF) if the speed of rotation (rpm) and the radial distance (r,^) are known: Place a ruler on the nomograph connecting the known values, rpm and r(mu The point at which the line intersects the RCF axis is the approximate relative centnfugal force (xg). High Speed Ultra Speed High Speed Ultra Speed The speed of rotation (rpm) can be determined in the same way if the RCF =~ -q and r^, are known — 25 20 18 16 E— 14 Use the right sided RCF...
