The KNAUER Online Degasser is a 2-channel for semi-preparative flow rates up to 50 ml/min. The degas (more)sing membrane is an innovative Teflon AF fluoropolymer which is more than 200x more gas permeable than regular Teflon and has excellent physical and chemical stability characteristics. Its high efficiency also allows for reduced internal chamber volumes– less than 7.7 ml per channel. For isocratic HPLC applications the 2 chambers of the semi-prep degasser can be connected in series for maximum degassing efficiency. For gradient applications, up to 2 eluents can be degassed simultaneously. For special applications, one degasser can also be used for multiple HPLC systems. The low dead volume makes reconditioning fast and minimizes solvent waste. Extremely low chamber volumes. Broad chemical compatibility is perfect for use in general HPLC applications Zero hysteresis even at higher flow rates No need to replace check valves or other parts even when under continuous operation Prevents air bubble spikes in the chromatogram Minimizes retention time fluctuations Minimizes gradient reproducibility problems Minimizes unwanted formation of chromophores which can disturb UV detection Minimizes unwanted oxidation or reduction which can disturb electrochemical detection Minimizes fluorescence quenching Technical Data: Dimensions: 85 x 165 x 315 mm (W x H x D) Weight: 2.5 kg Power Supply: 85 – 265 V, 47 – 63 Hz, 20 W Max. Flow Rate: up to 50 ml/min Number of Channels: 2 Degassing Method: gas permeation through Teflon AF amorphous fluoropolymer membrane Degassing Efficiency: < 0.5 ppm residual dissolved O2 at 1 ml/min Dead Volume: 7.7 ml Solvent Applicability: universal, except hydrochloric acid and halogenated hydrocarbons especially hexafluoro isopropanol (HFIP) Wetted Materials: PEEK, Tefzel, Teflon AF Vacuum Chamber: polypropylene and stainless steel

High-performance ultrasonic cleaner with heating for use in the practice, laboratory and workshop. T (more)he proven and particularly robust SONOREX ultrasonic baths clean thoroughly and gently by means of intensive cavitation bubbles, even in the hard-to-reach places of the cleaning objects. A user-friendly rotary handle control is used for easy setting of the cleaning time and bath temperature. The fully automatic SweepTec function prevents standing waves in the ultrasonic field and achieves particularly even cleaning. Ultrasound frequency: 35 kHz Temperature setting: 30°C – 80°C Time setting: 1-15 min, continuous operation Capacity: 45 L Work content: 30 L Level marking: yes Tub material: Stainless steel V2A (1 4301) Tub thickness: 2 mm Inner dimension (LxWxH): 500 x 300 x 300 mm Dimension (LxWxH): 540 x 340 x 500 mm Included Cover: A suitable stainless steel lid for an ultrasonic bath protects the bath fluid from external contamination and prevents odour nuisance caused by the added cleaning or disinfecting preparations. In addition, the noise emission that may be perceived as annoying during operation of the ultrasonic cleaner is reduced. The lids are designed in such a way that any condensation water that arises is led back into the tank. Hanging basket: For holding sound reinforcement material; made of stainless steel. During ultrasonic operation, nothing may be placed on the bottom of the tank, as abrasion may occur between the material to be sonicated and the ultrasonic oscillating tank. It is therefore recommended to use a suitable basket to hold the sonication material. The BANDELIN baskets are designed in such a way that the material to be sonicated is always in the optimum area of the cavitation field (1-2 cm from the floor) in the oscillating tank. With the help of a basket, the sonication material can also be conveniently placed in the unit and removed after operation, e.g. for rinsing, without the user coming into contact with the sonication fluid in the oscillating tank. Sieve holder: For cleaning test sieves in an ultrasonic bath; stainless steel. During ultrasonic operation, nothing may be placed on the bottom of the tank, as abrasion may occur between the material to be sonicated and the ultrasonic oscillating tank. It is therefore recommended to use a suitable basket to hold the sonication material. The BANDELIN baskets are designed in such a way that the material to be sonicated is always in the optimum area of the cavitation field (1-2 cm from the floor) in the oscillating tank. With the help of a basket, the sonication material can also be conveniently placed in the unit and removed after operation, e.g. for rinsing, without the user coming into contact with the sonication fluid in the oscillating tank. Insert strip: The insert strip is used to hold the insert vessels. When using chemically aggressive liquids (e.g. TICKOPUR J 80 U), removing chemically aggressive or abrasive contaminants or sonicating sample liquids, insert cups are used (indirect sonication). Because nothing may be placed on the bottom of the ultrasonic bath. Another advantage: When using an insert strip, several insert beakers can be sonicated with different liquids at the same time (e.g. removal of dental cements with STAMMOPUR Z in one and cleaning with simultaneous chemical disinfection of dental instruments with STAMMOPUR DR 8 in a second insert beaker). Please note that the surface tension of the water must be reduced in order to transfer the ultrasound to the insert vessel and therefore a cleaning solution (e.g. TICKOPUR R 33 – 3%) must be used as a coupling liquid / contact liquid.
