Compatibility of vials with solvents

Oct 11, 2003 · nonpolar solvents (e.g., hydrocarbons, toluene, and dichloro-methane) and is not useful for manipulations requiring these solvents. The objective of this work was to define the solvent compatibility of PDMS as a first step in discerning what types of solvents (other than water) can be used in microfluidic systems fabricated in this material.

Chemical & Material Compatibility Database This quick and easy tool allows you to select from nearly 600 chemicals to see how they effect 40+ materials used in fluid handling systems. Use the drop downs below to select a Chemical or Material and compare against the whole the database (ALL) or a specific requirement to your application.

Septum Selection Guide Septa for use with general chromatography vials, liquid injection 2-056 PTFE/Natural Red Rubber PTFE Natural Red Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR.

Oct 29, 2021 · Minisart® SRP25 Venting Filter 1757A----------Q, 0.2 µm hydrophobic PTFE. Minisart ® SRP with chemically inert hydrophobic PTFE is suitable for venting as well as harsh solvents with a pH of 1 - 14. Type 1757A with a pore size of 0.2 µm can be used for sterile venting. It has hose barb outlet.

• Solvent compatibility • Try to use pre-mixed solvents • Add 5-10% of organic eluent to the aqueous eluent • Add 5-10% aqueous eluent to the organic eluent • Avoids local crystallization in the pump (with buffers) • Eluents with salt buffers • Change eluents with salt buffers regularly • Filtrate buffers

Jan 17, 2022 · May 20, 2019 · Solvent Compatibility One of the first parameters to consider would be the diluent’s compatibility with the membrane material (Figure 1). Not choosing the correct filter membrane is a common problem that creates issues in HPLC; such as the introduction of extraneous extractables and reducing the detection of analytes.

Jan 20, 2022 · Solvent-Resistant Stirred Cells. The Millipore ® Solvent Resistant Stirred Cell is constructed from stainless steel and borosilicate glass for applications requiring compatibility with solvents. It is designed to offer a rapid and efficient method for concentrating or desalting samples of up to 300 mL under high pressure.

Nov 8, 2017 · • COMPATIBILITY STUDIES . ≠. EXTRACTABLE/LEACHABLE STUDIES • Compatibility studies often only look at physicochemical properties of DP when in contact with manufacturing components don’t always include E/L assessment. • First place to go is to vendor! Use extractable report to justify no need for leachable testing

2. Dissolving the synthetic material with a solvent or intro - ducing the solvent into the synthetic material to induce swelling and a change in the material’s mechanical properties. 3. The formation of tension cracks resulting from me-chanical stress and surface-active substances (deter-gents, oils). The stress can be caused by internal forces

Jan 18, 2021 · Glen Research offers a range of vials, columns, and bottles to meet specifications for your applications.

PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals. Review the chemical compatibility of Teflon® and PTFE with various chemicals, solvents, alcohols and other products in the cart below. Shop PTFE. Please Note: The information in this chart has been supplied by reputable

5182-0551: 4 mL wash vials with fill markings and caps, 25/pk 0 -40180: Diffusion inserts with black open top screw caps, 12/pk Washes and Pumps: Diffusion Caps Diffusion caps are important • Reduce volatile solvent diffusion • Better alternative than using vial septa, which will core, contaminate wash solvent vial →septum bleed peaks

20 mL headspace crimp top vials or screw top vials directly; no effort was made to purge the vials with an inert gas prior to capping. These vial blank samples were used for blank background and potential septa contamination evaluation. Solvent blank samples were prepared by adding 1 mL of solvent blank into a vial and then capping the vial

vials can withstand temperatures up to 500 °C for autoclaving and derivatization applications. However, plastic vials are also available in a wide range of volumes and configurations. Breakage is not an issue with plastic vials, and they are non-reactive with most sample chemistries. Plastics are also: l compatible with many solvents (see Table 1)

Like all polyolefins, polymethylpentene is non-toxic, non-contaminating and lighter than water. Its excellent transparency, rigidity and resistance to chemicals and high temperatures make PMP a superior material for labware. PMP withstands repeated autoclaving. It can withstand intermittent exposure to temperatures as high as 175°C.
