Innovative Top Buret sets new standards for manual titration. Its pulse-free dispensing technique allows the desired volumes to be dispensed continuously, thus making titration simpler and safer, with precision values well within required limits. The volume is dispensed by simply rotating the wheels: Model M features a dispensing rate of 2,500 Ýl per rotation; Model H features a rate of 5,000 Ýl per rotation. The display readings on both models range from 0.01 ml to 999.9 ml.. This bottle top buret is extremely sturdy, and its user friendly display and control features provide simple, fatigue-free operation. Top Buret features : Continuous, pulse-free dispensing technique for rapid titration Recirculation valve with valve toggle Dispensing range from 0.01 ml to 999.9 ml Highly resistant to chemicals Voltage supply with long-life primary cells and charging display Removable electronics unit Modular, service-friendly construction Simple calibration program Discharge tube can be rotated a full 360Ý Adjustable discharge tube horizontal: 142–220 mm, vertical: 10–200 mm Telescopic filling tube for automatically setting the length from 210 mm to 370 mm Thread adapters for all commonly used bottle types provide maximum flexibility for the user

These electronic dispensers combine easy handling during dispensing with a broad range of features! The Repeater® E3x offers additional high-end applications, such as titration and aspirating of supernatants or sequential dilutions. In combination with the Combitips advanced®, it is an essential lab tool for all kind of liquid handling. The Repeater E3/E3x in combination with the Combitips advanced® creates a versatile dispensing system that functions according to the positive displacement principle and is therefore capable of pipetting any liquid while maintaining the highest standards for accurate results. The motor driven dispenser gives you full volume control, improved accuracy and reproducibility while reducing physical strain during use. The repetitive dispensing modes contribute to reducing fatigue by decreasing the number of movements for the user; filling the tip once allows dispensing up to 100 times. The system is an essential lab tool ideal for all liquid handling applications, accommodating more than 5,000 different dispensing volumes between 1 μL to 50mL. Consumables Combitips advanced tips easily attach to the Repeater; their built-in sensor recognizes the size of the tip, and the volume appears automatically in the display—eliminating time-consuming volume calculations and incorrect dispensing volumes. The nine sizes of Combitips advanced allow a wider dispensing range of up to 112 different volumes and longer series dispensing (e. g., 100 x 250 µL) without stopping for a refill. Always contamination-free! Combitips advanced tips function according to the positive-displacement principle, which ensures that the correct volume is dispensed regardless of the density or viscosity of the liquid. The positive displacement system provides safer dispensing of solutions that contain radioactive and/or toxic substances, as well as solutions that have a high vapor pressure, because no aerosols are formed. Combitips are easily replaced—eject with the push of a button— and dispose after use, always contamination-free. Features Automatic Combitip recognition: Eliminates time consuming volume calculations, avoiding incorrect dispensing volumes Ergonomic one-button tip ejector: For one handed operation and contact-free Combitips advanced ejection Speed Adjustment: Program aspiration and dispensing speed for the utmost in precision and accuracy while also preventing splashing Repetitive dispensing modes: Decrease the number of movements for the user by allowing them to fill the tip once and dispense up to 100 times without a refill Wide dispensing range: 1 μL to 50 mL provides up to 5,000 dispensing volumes with increments as low as 100 nanoliters Motor driven function reduces the human error to a minimum and reduces risk of repetitive strain injuries (RSI) Safe and ergonomic operation with 9 different selectable languages Large illuminated color display reduces eye strain when reading Positive displacement system: Not affected by liquid properties, most manual pipetting errors and provides protection from aerosol contamination Eppendorf TrackIT compatible: Editabled data chip contains all relevant information Applications Repetitive dispensing of volumes in long series such as tube or plate filling, aliquoting reagents and kit usage (Dispensing/Automatic Dispensing modes) Contamination-free dispensing for toxic, radioactive and other hazardous liquids (all available modes) Precise and accurate dispensing of viscous solutions (e.g. glycerol) or liquids with high vapor pressure (e.g. ethanol) (all available modes) Pooling of supernatants (Aspiration mode) Creation of dilution Series (Sequential Dispensing mode) Concentration Determination (Titration mode) Pooling and volume determination with subsequent dispensing (Aspirate and Dispense mode) Conclusion The Repeater/Combitips system is a sophisticated solution for repetitive liquid handling applications. These contamination-free manual and electronic systems are designed with your productivity and safety in mind—especially when working with hazardous, volatile or viscous liquids.

Centrifuge 5424 R is a versatile and powerful 24-place refrigerated model, available with either rotary knobs or an easy-to-clean keypad. Temperature range is –10ÝC to +40ÝC, with a guaranteed +4ÝC at the maximum speed o 21,130 x g (15,000 rpm) and continuous cooling at the end of the run. Additional rotor options include a special Kit rotor™ or 18 x spin columns, designed with an extra high rim to support open tube lids during centrifugation, as well as a specia PTFE-coated rotor for increased chemical resistance and easy cleaning. Simplicity of operation, the ability to operate quietly without the rotor lid, and a FastTemp function which cools the microcentrifuges quickly, for Centrifuge 5424 R from approximately 21ÝC to 4ÝC in only 8 minutes – all contribute to an increase in laboratory efficiency. 5424R benefits from the patented compressor technology which reduces vibrations and protects samples. Applications for this microcentrifuge range across molecular biology, biochemistry and biotechnology, from isolation of DNA, RNA or proteins and pelletizing of cells, to aerosol-tight centrifugation of infectious samples.
