Applications
Guanidine hydrochloride can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA. It is a strong chaotropic agent useful for the denaturation and subsequent refolding of protein, it can solubilize insoluble or denatured proteins such as inclusion bodies and be used for the recovery of periplasmic proteins. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA.
Product Description
The crystal structure of Guanidine hydrochloride consists of a network of guanidinium cations and chloride anions linked by N–H•••Cl hydrogen bonds,it is a strong chaotropic agent.Guanidine HCl may agglomerate upon storage. It may appear as a free-flowing crystalline powder, a freeflowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical

Supplier: Thermo Orion

This rugged, waterproof portable meter is designed for a wide range of pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity and temperature testing and field applications. It can be used in the most demanding locations thanks to its IP67-rated housing. The meter offers two measuring channels allowing users to measure pH and conductivity simultaneously or view each channel separately.

Supplier: GRAM

The unique air distribution system combined with a finned tube evaporator results in excellent temperature consistency for biostorage: the evaporator design eliminates the risk of 'cold walls', which can damage delicate items stored touching the sides of the cabinet. Whilst the air distribution system which directs the cold air down the rear of the cabinet and back up to the evaporator fan at the top, ensures a uniform temperature throughout.

Planetary mills pulverise and mix soft, medium-hard to extremely hard, brittle and fibrous materials quickly without loss. Examples of applications include minerals, ores, chemicals, ceramics, soils, household and industrial waste and sample preparation for spectral analysis. These mills are suitable for long term trials and continuous use and are used for dry and wet grinding in all industry sectors, where a high degree of reproducibility, fineness, purity and speed is required. The excellent performance is achieved by the high centrifugal forces and very high pulverisation energy generated by the planetary mill design. The control system allows the operator to control speed, grinding time, direction reversal and interval times. The mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. Safety features include automatic safety self-test and a noise protected and ventilated chamber. A backup memory in the event of power failure ensures storage of remaining grinding time. Grinding sets are available in six different materials that allow sample preparation without contamination.
