What Chemicals are Compatible with PTFE and Teflon®*? Low temperature: maintains high strength, toughness and self-lubrication as low as 5°K (-268°C /-450°F) and good flexibility at 194°K (-79°C / -110°F) PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals.

chromatography, well plates are only rarely used. Here are reasons why some applications require a glass vial: A) Glass vials are used because in chromatography, organic solvents are used and therefore a solvent stable and inert sample handling container is required. B) Vials are sealed tightly and reliably with caps and

3. Broad chemical compatibility choose for filtering aqueous and organic solution low protein binding. 4. Filtration of aqueous solutions as well as organic solvents and chemicals. 5. Eliminating the need for multiple filter types in the lab. 4. RFQ. 1. What is the membrane material? Answer: PP for pre-filter and PTFE Hydrophilic. 2. What is

Troubleshooting protein loss during ion exchange (IEX) chromatography. The main cause of low protein recovery or yield during ion exchange chromatography is poor binding of the protein to the ion exchanger. There are several reasons for poor binding. Explore the five troubleshooting tips below for maximizing your protein binding and recovery

* Low protein-binding for filtration of non-aggressive aqueous and mild organic solutions. * Low UV absorbing extractables and low nonspecific protein binding. * Two types in pore size:0.22μm and 0.45μm. * Three types in filter size:13mm, 25mm and 30mm. 2. Related Services * Prompt logistic service. * ODM service. * Field inspection service. 3.

AQ™ Syringe Filters can be compatible with aqueous or organic HPLC solvents and have been designed to be extremely low adsorbing even for charged molecules and extractable free from the first 0.2ml of filtration. The uniquely designed outflow path of the 25mm device has 16 channels for minimum back pressure. This allows the user to apply less

Equilibrium dialysis (ED) is one of the most frequently used approaches to investigate drug binding, where the major drawbacks are the time to reach equilibrium (varying between 6 and 24 h), a long assay preparation time and complexity of automation. A rapid equilibrium dialysis (RED) device has rec

Quality vials are essential for reliable analytical results. All Aijiren Technology Certified Vials are tested by LC or LC/MS to assure quality and cleanliness. The test results confirm the vials, cap and septa have been properly manufactured, handled and packaged, and are free from any potential contaminants which could result in chromatographic ghost peaks.
