Centrifuge tubes

Conical bottom centrifuge tube is used for testing of petroleum products. Scale and legend are durable white ceramic enamel except California type. Top is tooled to accept snap cap. Conforming to USP Type I and ASTM E438, Type I, Class A requirements.

• Wall thickness approx.: 1 mm
• Maximum loading: 3500 x g rcf.

Thin channel, crossflow filter units with 50cm² / 200cm² filter areas for capacities between 100ml / 500ml and 5L. This system provides high crossflow rates at minimum pumping pressure and does not require additional fittings for scale-up. VivaFlow 50 is easy to operate with a flow restrictor and, optionally, a pressure indicator. Modular construction with luer connections allows interlocking of units in series for easy scale-up. Recovery rates are maximised due to optimised recirculation volume and by use of low adsorption materials. Disposable.
For greater volumes, VivaFlow 200 is available with a filter area of 200cm² and includes pressure indicator, flow restrictor, filtrate tubing and connectors.
Membrane: polyethersulphone

These tubes coloured by silver ion diffusion are particularly suitable for handling UV-sensitive substances. The tubes are manufactured from borosilicate glass 3.3 which is conform to USP Type I and ASTM E438, Type I, Class A. They are supplied with a green cap.

For Oak Ridge centrifuge test tubes made of PP, PC and polysulphone.

Transparent, graduated tubes made of polypropylene copolymer. Good chemical resistance, autoclavable. For centrifugation in cooled and uncooled centrifuges. 50 and 100 ml tubes with reinforced rim.
