Centrifuge tubes

Centrifuge bottle with 2L capacity.

• Separating large volumes up to 12L
• Centrifugation up to 7333xg, at temperatures from 4°C to 22°C
• Bottle meets the requirements of USP VI
• Non-cytotoxic, not hemolytic
• PPCO bottle, PP seal screw cap with silicone seal
• Graduated, total volume of 2380ml
• Excellent chemical resistance
• Before autoclaving, unscrew the cap and place it on the bottle neck
• Bottles must always be at least 80% filled

The closure design features a two-piece plug and sealing cap to support aseptic handling techniques. Use of the two-piece closure system protects the bottle contents from contamination when the support bridge is applied and removed from the bottle. The plug includes a retaining ring to ensure and maintain the placement of the gasket during use.

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.

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
