These sizes are sufficient for HPLC use. The smallest known sterile syringe microfilter have pore sizes of 0.02 μm. Membrane diameters of 10 mm, 13 mm, 25 mm are common as well. Some syringe filters for small volumes may not resemble a wheel at all. The syringe filter body may be made of such materials as polypropylene and nylon.
The pipette controller syringe is a Hamilton Gastight® Luer Tip syringe modified with a special free-sliding, thumb-wheel plunger. The syringe is supplied with 41 mm (1-5⁄8”) of clear vinyl tubing, 3 mm ID (0.125”) x 6 mm OD (0.250”), to attach a pipette to the syringe’s luer tip. The syringe draws liquids into the pipette (liquids
Use only clean, HPLC-grade solvents. A dirty solvent can cause baseline noise and drift and clog solvent filters with particulate matter. HPLC-grade solvents generally maintain their purity from lot to lot; use them to ensure the best possible results. After adding solvent modifiers (buffers) and adjusting pH, filter the solvents using a
Sep 28, 2016 · The majority of syringe filters used do not allow you to reclaim the solid. They are often used before analysis to remove any solid, undissolved, material. Other, filter holder (in-line) types allow you to regain your filter (Figure 1). Syringe filters normally use membrane type filters which have a specific particle size cut off (e.g. 0.45 μm).
HPLC/UV chromatograms of common proteins and comparison of unfiltered sample to filtered sample using an Aijiren Captiva Premium PES syringe filter, 0.2 µm, 15 mm. D: Dimer, M: Monomer. Filtration recovery % (FR) = × 100%

If you are looking where to buy syringe needles, Hamilton Company offers the widest variety of standard syringe needles and custom lab needles in the industry. Manufactured from 304 stainless steel and with needle gauges from 10 to 34, and lengths from 0.375 to 12 inches, almost any syringe needle is possible. Multiple hub styles available
Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime.
biggest amongst premium syringe filters and the MBS housing is color-coded for easy pore size identification. See page 10. Medical Use and Sterile Venting Special Applications Minisart® syringe filters are ideal for clarification of liquids laden with particles, e.g. for preparation of pharmaceuticals or infusion solutions.
PTFE Syringe Filters. PTFE Syringe Filters are universal filters that are inert to a wide variety of aggressive solvents and strong acids and bases. These syringe filters can also be exposed to high temperatures and are an excellent choice for HPLC sample preparation.
syringe filter device technique: Ease of Use: No need to use cumbersome, individually wrapped disposable syringes. With the Alliance Filtration System you can use disposable pipette tips which are less costly and easier to use. Saves Time: The conventional syringe filter technique is a one-at-a-time filtration process.
Sep 30, 2021 · Since 1875, Shimadzu is pursuing leading-edge science and technologies in analytical and measuring instruments including chromatographs and mass spectrometers, medical devices, aeronautics, and industrial equipment.
Syringe Filters. Syringe filters with high burst strength for assured performance. Manufactured to ISO 9002 and GMP standard and 100% integrity tested. Syringe filter sizes include 4, 15, 25, or 26 mm diameter to handle volumes ranging from 0.5 to 100 ml. The 50 mm diameter PTFE syringe filter are ideal for protecting the vacuum line and pump.
Minisart® syringe filters are ideal for clarification of liquids laden with particles, e.g. for preparation of pharmaceuticals or infusion solutions. For sterilization and removal of particles from air and other gases, syringe filters are optimal for sterile venting of containers, bioreactors, fermenters and tubing systems in medical devices.
