Are You Paying Too Much For A Syringe Filter?

Syringe filters are disposable filter cartridges that are connected to the ends of syringes. The fluid that needs to be cleaned can be cleaned by drawing it up the syringe via the filters. During Schlenk line operations that often use needles and syringes, syringe filters were appropriate.

Although not always, syringe filters may contain Luer-lock fittings. They are reasonably priced and suitable for ordinary filtration. For users to know whether their goods are compatible with organic solvents or aggressive liquids, the majority of firms publish suitability wall charts.

A syringe filter typically comprises a membrane acting as a filter inside a plastic casing. 0.22 mm and 0.45 mm holes are the most prevalent sizes. The most typical membrane diameters are 13 mm, 25 mm, and 30/33 mm. Before an HPLC analysis, syringe filters can also be used to remove contaminants from a solution. Pore diameters in the lowest sterile syringe microfilters are 0.02 micrometers. Syringe filters are also provided for removing microorganisms and filtering gases.

The syringe filtering marketplace

To the best of my knowledge, syringe filters are the laboratory item that is sold by most vendors. If you have issues with a syringe filter manufactured in China, there is no accountable agency in the United States. Almost every vendor at Pittcon has syringe filters for sale.

They receive a tonne of emails from Chinese suppliers who provide syringe filters. In addition, EMD Millipore, Pall Life Sciences, GE Whatman, Corning, and VWR Private Label are also industry leaders. Hundreds of vendors compete for a small section of the market.

What Constitutes a "Good Price" for Syringe Filters?

The price rises in direct proportion to brand recognition. The American businesses that buy under their trademark from Asia at a price of around $0.80 per syringe have been at the bottom end of the spectrum. The syringe filter known as PES is not sterile.

While well above $3.00 each, GE Whatman filters are the most expensive. Its Fisher and VWR private-label membrane filters, which cost around $1.25 each, are in the middle of the crowd. Additionally, if you bought directly from China, users could get this filter for about $0.40 per unit.

Do brand names come with a price?

Users will spend $30,000 on filters if they buy a $3 filter and use it 10,000 times per year. You'll pay $4,000 on the opposite side of the scale; do you value that $26,000 distinction? Occasionally, yes.

A test that is already performing will incur significant expenses if additional variables are added. This is because scientists are nervous about taking a chance by introducing additional variables to successful tests. Let's examine the dangers and how they apply to the tests you are performing.

1. Sampling contamination

This depends on the syringe filter's condition or whether or not substances will leak into the housing as well as the filter. Additionally, non-filtered elements could enter your sample if the filter is over-pressurized.

2. Retaining samples

Filter breakdown or even at the very least, excruciating hand and wrist cramps are possible when the filter is overloaded with particles or highly viscous substances. If you can tell anything is very "dirty," a pre-filter or even an additional filter may have been the answer to this issue.
