Fittings for HPLC

1 Can I use a PEEK finger tight fitting on stainless steel tubing? Can I use a SS fitting on PEEK tubing?

Yes, you can very effectively use PEEK fittings on stainless steel tubing as long as you take into account the making pressure ratings of the fitting you are using and the expected pressures in your system.…

2 Can the UHPLC fittings made for PEEKsil hold the same pressure on PEEKSil as with PEEK tubing?

The nature of the problem of using PEEKSil tubing is over tightening a fitting, which can break the PEEKsil tubing. It's happened on occasion with our fittings, but the same holds true for many fittings…

3 Do all PEEK fittings fit all receiving ports?

No, you must consider if the receiving port is metric or English, the thread diameter, the pilot length of the receiving port, the thread count and the pressure expected. If you are not sure if your fitting…

4 Do I need a connector when using the Cartridge Columns that use WVS Hardware?

The WVS (Whatman Void Sealing) cartridge columns use a unique sealing system to ensure compression of the packed bed even if a void develops. All of our WVS cartridge column products require the use of…

5 Do I need the ferrule placement tool to install UPLC fittings to stainless steel tubing?

The UPLC fittings can’t be properly attached to the stainless steel tubing without using the ferrule placement tool (cat# 47327-51). If you use it without the secondary ferrule, you won’t have the…

6 Do the High Pressure Tee Fittings require ferrules or flat-bottom (flangeless) fittings?

The High Pressure Tee fittings require ferrules. Only the low pressure Tee junctions require the flat bottom fittings. High Pressure Tee Fitting Product Page © Copyright MicroSolv Technology Corporation,…

7 Fittings defined for chromatography

The dictionary defines a fitting as “a small often standardized part used to join other parts together properly.” This is very similar to what plumbers refer as fittings. For the use of chromatographers,…

8 How do I choose the correct column coupler for my instrument?

We offer a variety of column couplers. To find the correct size, simply match your tubing internal dimension (ID) to the coupler. The different Coupler colors correspond with those of the HPLC tubing…

9 How does the Clean-Cut90™ tubing cutter work for cutting PEEK tubing?

Clean-Cut90™ Tubing Cutter for PEEK Tubing Tubing Cutters Product Page The blade of the Clean-Cut90 tubing cutter has 2 sides to consider. One side (marked on the tool with an arrow) gives a perpendicular…

10 How one fitting for chromatography differs from others.

Of course, the quality of the manufacturing is important but besides that the most important features of all fittings are: Geometry of the receiving port you are putting the fitting into. Threads on the…

11 How to connect HPLC column connectors

HPLC Column Connectors So Easy... Anyone Can Use It! Assembly Instructions for the HPLC Column Connectors Push connector into port until you can engage its threads in the threads of the port. Turn clockwise…

12 I am using TFA and someone told me that I might have a problem with my Delrin type fittings. Is this true?

That person is correct. Delrin is not compatible with Trifluoroacetic Acid. If it comes in contact with your fittings, it could become compromised and your connection might slip and become less than perfect.…

13 Is PEEK tubing or PEEK fittings autoclavable?

Yes, many scientists have used PEEK successfully when autoclaving PEEK tubing and or PEEK fittings using gamma irradiation, heat or ethylene oxide. PEEK tubing information © Copyright MicroSolv Technology…

14 Is stainless steel tubing or fittings autoclavable?

Yes, many scientists have used 316 stainless steel successfully when autoclaving tubing and or fittings for HPLC using gamm irradiation, heat or ethylene oxide methods. Stainless steel tubing information…

15 Solvents and solutions that should be avoided when using PEEK fittings or tubing.

The solvents and chemicals that should be avoided when using PEEK tubing and fittings include: Nitric acid Sulfuric acid Halogenated acids, including hydrofluoric, hydrobromic, and hydroiodic acids Pure…
