供应商: HEIDOLPH

描述: Models PD 5201 and PD 5206 for advanced requirements. Peristaltic pumps are ideal for transporting and metering aggressive, abrasive, or corrosive solutions, and also for sterile media under low pressure. The medium to be transported only comes into contact with the tubing, so there is no contamination. Suitable for transporting highly viscous media up to 10000 mPas. The pumps are self-priming without seals or valves. Can be used in the food industry for filtering and separating, for water treatment, in biotechnology and routine laboratory applications. Media can be transported under pressure and under vacuum. Maintenance-free motors ensure long service life. Quantities displaced by the pump heads are stored in the program depending on the individual tubes used, and are shown in the digital display. Software may be ordered separately as an accessory. The pump drive is microprocessor-controlled. Equipped with RS232 digital interface; speed, metered quantity, flow rate, pause, and tube dimension can be controlled. Digital display of speed (min⁻¹) and flow rate (ml/min). Digital display of displacement volume (ml) in the case of volume metering. Intermittent metering is available with adjustable pause times. A metered volume can also be specified in addition to the flow rate display. Extremely simple calibration of displacement volume (ml) and flow rate (ml/min).

目录号: (GRANTBT-T100IN)

供应商: GRANT INSTRUMENTS

描述: This convenient and effective system was developed in conjunction with the Royal Postgraduate Medical School of London University to produce large batches of uniform tuberculosis culture medium four to six times per day. Vessels containing culture medium are incubated on a shallow tray which is in contact with water held at a constant temperature of 85 ºC within a tank, ensuring that the temperature of the vessels is constant. Inspissation takes 50 minutes at 85 ºC. It is robust and durable as the tray, tank and outer case are made of polished stainless steel. Water temperature under the tray is controlled by a digital immersion thermostat for accuracy and reproducibility of set temperature. All moving parts are incorporated in the control unit which is easily removed for cleaning. An insect resistant blanket and quilt are placed over the containers to provide thermal insulation and exclude draughts.

描述: 5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser Also called AIM or activation inducer molecule, CD69 is a gp28/34 disulfide bonded homodimer with a Mr of 60 kDa under non-reducing conditions. CD69 contains one or two N linked oligosacaride. The CD69 molecule is also present on activated platelets. In normal peripheral blood a variable percentage of cells express the CD69 antigen. It is involved in lymphocyte signal transduction.

描述: With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in gradient grade; as well as isocratic grade. This enables to minimise the gradient effect of the solvent involved.

描述: With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in 'gradient grade' as well as 'isocratic grade'. This minimises the gradient effect of the solvent involved.

目录号: (IKAA3691100)

供应商: IKA JANKE KUNKEL

描述: Multi-position digital magnetic hotplate stirrers with 5, 10 or 15 stirring positions, designed for synchronous heating and stirring, suitable for continuous operation. The wear-free magnetic coils provide noiseless and consistent stirring at all positions. Screening can be performed under reproducible conditions. The surface temperature is infinitely adjustable up to 120 °C, producing a maximum medium temperature of 70 °C (depending on type of vessel). Speed remains constant, even when load changes.
