The C-MAG HS 7 magnetic stirrer has a chemically resistant ceramic square top, it offers precise temperature control. Units can stir up to 20 L (H₂O) and have a speed range of 50 to 1500 mim⁻¹.

Supplier: IKA

Compact digital magnetic stirrers with a chemically resistant ceramic top offer precise temperature control. The elevated control panel minimises contact with spills and enables easy reading and adjustment of the temperature. Units feature three operating modes: Standard, safe and adjustment protection. Stirrers have a digital error code display, a 'hot' top indicator to warn user that surface is hot and the strong magnetic adhesion prevents stirring bar decoupling.

Supplier: Thermo Fisher Scientific

Magnetic beads are a convenient affinity support for a variety of assays, which allow easy purification of the target without columns or centrifugation. After a binding step in an affinity purification procedure, the magnetic particles are easily and rapidly collected by placing the microcentrifuge tube or reaction vessel next an appropriate rare-earth magnet. MagnaBind™ beads respond rapidly to MagnaBind™ magnets but can be easily dispersed and regathered multiple times (ie. they will not irreversibly aggregate) because they do not have any magnetic memory.

The RCT basic magnetic stirrer provides reliability, an exceptionally long product lifetime and the highest safety standards. RCT basic is suitable for stirring tasks up to 20 L (H₂O) and reaches temperatures up to 310 °C. With the connection option for an external temperature sensor (PT1000.60), the temperature can be measured and controlled directly in the reaction medium. Thanks to insulation of the aluminium heating plate, maintenance-free EC motor and electronic switching power supply, RCT basic features excellent energy efficiency as well as reduced self-heating of the heating plate during stirring operation, contributing to a more sustainable laboratory.

Supplier: Cytiva

Sera-Mag Oligo(dT)-Coated Magnetic Particles enable convenient mRNA isolation and extraction. Sera-Mag Oligo(dT) Magnetic Particles bind target mRNA through pairing of the polyadenylated RNA tail found on the 3' end of mRNA to the covalently bound oligo(dT) groups on the surface of the particles. This binding is easily accomplished using standard hybridisation conditions. Versatile and efficient methods for mRNA purification are critical, given that eukaryotic mRNA makes up only 1 to 3% of total cellular RNA. Sera-Mag Oligo(dT) magnetic particles remove 90% or more of mRNA from total RNA with just one extraction.

RET control-visc safety magnetic stirrers with heating and integrated balance which are suitable for unsupervised operation. Clear, multilingual TFT display makes it easy to set all parameters and the sealed casing ensures a long service life. Integrated temperature control feature enables connection of a temperature probe, placed directly in the medium, to control medium temperature with a high degree of precision. The stainless steel composite hot plate (white units have a chemically resistant enamelled plate), reaches a temperature of 340 °C, enabling rapid heating. RS232 and USB interface enables PC control of the magnetic stirrer and documentation of all test parameters. 'Lock' function prevents inadvertent changes of speed and temperature settings. As a safety feature, a 'hot' sign flashes when the unit is switched off but the heating surface is still hot. Unit has a DIN 12878 socket for connecting an electronic contact thermometer, for high precision temperature control and also features detached magnet detection and has a BNC socket for a pH electrode.
