"These syringe filters offer a choice of filter media: hydrophobic PTFE membrane for exceptional chemical and temperature compatibility -hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without prewetting -GHP (hydrophilic polypropylene) membrane for low protein binding -and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous
Juvéderm® Voluma® XC is the only hyaluronic acid filler that is FDA-approved to instantly add volume to the cheek area. It can also last up to two years with optimal treatment. If you’re looking to plump cheeks that have sunken over time, this injectable is a quick, convenient approach to skin care.
The choice of syringe size should be based on the known effects of syringe size on the strength of vacuum generation, the force required to generate a specific level of vacuum, the difficulty to generate vacuum, the volume of fluid to be aspirated or the required biopsy yield, needle control, and patient safety considerations [1–13].
Refer to the needle gauge chart to choose a needle gauge with an appropriate µL/inch before selecting a needle. Select the minimum needle length that allows you to carry out your application comfortably. Note: The ‘s’ on a 22s needle represents a smaller I.D. (inner diameter) for the needle and a thicker needle wall for better durability.

Feb 17, 2020 · Open the syringe filter package so that you can later pick the filter up easily, especially for individually packed sterile syringe filters. a. For sample volume < 10 mL. Draw a small amount of air (about 1 mL) into the syringe before loading the sample solution. The air is used to purge the filter to minimize hold up volume.

Syringe Filters - Pall Corporation. Another aspect of choosing the right filter size is the hold-up volume. This is the volume of liquid remaining in the filter after use. A filter with a low hold-up volume is recommended for use with expensive fluids or those with limited availability.
The fluid remaining inside the filter is typically referred to as the “hold-up volume.” The hold-up volume for 25 mm syringe filters can be in excess of 1 mL and can make filtration of samples smaller than 2 mL very difficult, if not impossible, to filter. There are three ways to reduce the hold-up volume in a syringe filter. 1. Use a 13 mm
Superior filter areas of up to 6.2 cm 2; Pore sizes ranging from 0.1 μm to 5 μm; Low adsorption properties; CE-Minisart ® syringe filters For medical use. Image Credit: Sartorius Lab
