The VP 220 is ideal for rotary evaporators providing the powerful vacuum needed for demanding evaporations without the use of oil pumps. VP 220 has built-in Advanced Vapour Management (AVM) which means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases. The VP 220 is especially effective for rotary evaporation of low boiling point solvents such as acetone and ethanol and is able to rapidly strip DMF at 35 °C. The pump parts are all made of corrosion resistant materials such as PTFE and Kalrez to handle aggressive vapours, and together with vacuum adjustment, the evaporation process will be optimised. Use the vacuum adjustment to increase the vacuum until bubbles form in the evaporation flask - then lower it slightly. Reduce the vacuum for fast reaction to bumping or foaming.

Supplier: VWR Collection

Ideal for molecular biology applications, mechanical and chemical cell lysis, mixing tissue samples, mixing cytogenetic suspensions, and vortexing cell suspensions. Shaker is also ideal for emulsification of bi-polar viscous fluids and for mixing fluids in small diameter tubes. Specifically designed to shake and/or vortex microplates in timed or continuous modes. Shaker features programmable timed mode from 1 s to 160 hours. Speed and time are easily adjusted with the up/down arrows on the front panel.

pH adjusters are used to adjust the pH of formulations. This category includes acids that are notoriously difficult to source as truly cGMP-produced and amino acids that most companies do not fully test for EP, BP and JP. Avantor provides all that and more with our cGMP-produced acids and mutli-compendial amino acids.

Ready to use molecular biology grade dNTP mixes and dNTP sets. The dNTP mix is designed to save hands-on time for researchers, and reduce the possibility of contamination by reducing pipetting. dNTP solutions are also available in sets of four individual dNTPs, each 100 mm. Both are convenient for use in DNA polymerisation reactions, DNA labelling and sequencing processes.
