Sigma Aldrich Fine Chemicals Biosciences TRI ReagentR for processin
TRI reagent(R) is a quick and convenient ready-to-use reagent useful for efficient total RNA extraction or for the simultaneous isolation of RNA DNA and protein. TRI reagent(R) is a mixture of guanidine thiocyanate and phenol in a monophasic SOLUTIONon. Homogenization or lysis of the tissue sample in TRI reagent(R) dissolves RNA DNA and protein. The addition of chloroform or 1-bromo-3-chloropropane followed by centrifugation results in the separation of the mixture into three phases an aqueous phase containing the RNA the interphase containing DNA and an organic phase containing proteins. Each of the components can then be isolated after separating the phases.

Sigma Aldrich Fine Chemicals Biosciences WilmadR low pressure/vacuu1EA
Novel low pressure/vacuum tube for NMR and EPR spectroscopy. A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. Offers a convenient flame-free sealing SOLUTIONon for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.features Greaseless PTfE piston provides a 100% contamination-free seal. Axial symmetric design guarantees its application in spinning experiments.Economical. reliable CAUTION Due to the nature of glass Extreme Caution should be exercised when using at elevated or reduced pressures as performance of tubes under pressure or vacuum cannot be guaranteed. Adequate safety shielding should always be used when working in these conditions.
