Description: These lightweight Standard Line pipettes feature a revolutionary suspension system which allows the shaft to retract slightly when pressed against a row of pipette tips. Each shaft moves independently, resulting in an even sealing force being applied to all 8 or 12 tips. The suspension system not only ensures secure tip sealing, but also eliminates tips being jammed.

Description: Digital block heaters which hold from one up to four aluminum blocks, provide precise temperature control in small vessels. The PT1000 temperature sensor allows temperature control directly in the sample vessel. It is used with PCR tubes, PCR strips, Greiner tubes, microplates and cuvettes. The block heaters are ideal for melting and boiling point determination, enzyme reactions, incubation and activation of cultures, immunoassays, DNA denaturation, culture media tests, coagulation tests, blood/urea nitrogen determinations and <i>in situ</i> hybridisations.

Description: Standard close-it and close-it food & pharma control seals are also available on a continuous roll. This offers the flexibility to provide a small length of tape to seal a small hole or to mark a specific point. Alternatively, longer pieces can be used to repair a long tear quickly, reliably and easily. With its extremely strong adhesive strength, close-it tapes adhere to a range of different surfaces, where the glue effect of normal adhesive tape quickly reaches its maximum capacity.

Description: 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: MEMMERT

Description: This steriliser complies with all relevant standards and regulations for medical products and guarantees reliable programme sequences, irrespective of the load and chamber volume. Especially due to the SetpointWAIT function the validation of this hot air steriliser is possible anytime. The SetpointWAIT function ensures that the programme is only continued when the setpoint temperature has been reached. Precisely maintaining the sterilisation time and thus completely killing off even highly resistant microorganisms is therefore guaranteed at all times, irrespective of the sterilisation load and chamber volume. This feature can also be used with additional, freely positionable Pt100 temperature sensors. In this case, sterilisation only begins when the setpoint temperature has been reached at all measurement points – that is, in the load. For the special application of depyrogenisation, the hot-air steriliser is absolutely ideal. The SF models are equipped with single display.
