Weigh a 400 or 600 mL beaker. Weigh a piece of filter paper. Add between 5 to 7 mL of distilled water to the NaCl-SiO 2 mixture and stir gently for 5 minutes. Following the procedure outlined by the instructor (see the figure below), filter the sand-salt solution through the pre-weighed filter paper in the funnel into the pre-weighed beaker.
Cuvettes by Volume. The most widely used cuvette is square type with an external dimension of 12.5 x 12.5 mm and a height of 45 mm and an internal size of 10 x 10 mm. This is a standard dimension for which most spectrophotometers and fluorometers holders are designed.
Never use Nylon filters and always PTFE filters for your samples. The most common peaks are 325, 311, 274. The contaminations appears with the less of 14 (CH2).
Glycerol may be sterilized by autoclaving for 15 minutes and should be stored in small aliquots to prevent introduction of contaminants. DMSO should be sterilized by filtration with a 0.2 µm nylon syringe filter and stored at -20°C in small, single-use sealed aliquots.

The replaceable in-line filter prevents partic ulate matters generated by the mobile phase or piston seal from reaching the HPLC column. The inlin e filter is usually made of stainless steel or polyetheretherketones (PEEK) with 0.5 m to 2.0 m pore size. Another important component of the HPLC syst em is the injection valve.
Jan 19, 2015 · The filter was subsequently removed, and the filtered material was transferred into 1 of 5 scintillation vials. After visual inspection of each solution, the color and clarity of each were recorded and any discrepancy between the filtered solutions and the control solution was documented.

This medical grade micro size thin wall PTFE tubing absorbs practically no common acids, bases or solvents. Do not confuse this grade of tubing with general purpose, commercial & industrial grade PTFE tubing ; although it can be used in those applications.
The resulting supernatant was added to the 10 mL volumetric flask with the C-18 eluant. Deionized water was used to bring solution to volume before mixing with a small magnetic stirring bar for up to 5 minutes. About 1.5 mL of the solution was filtered into a HPLC autosampler vial using a 0.45 nylon filter (Aijiren Techbrand).

Close the lid and do the auto zeroing. There is a manual placed next to the machine you may refer to it anytime. Switch on the machine and wait for it to initialize. So on the control panel we press the button “2” to access the spectrum. On the screen we will see the scan range and we should assign it as 800 nm – 400 nm.
