1 Additional Specifications for HPLC Low Pressure, PFA Tubing.

Some extruders of PFA tubing list the specifications below on their website. Physical Density (g/cc): 2.12 - 2.17 Water Absorption (%) < 0.03 Standard Percent Crystallinity (%): 48 - 70 Refraction…

2 Are the ends of the Pre-cut Stainless Steel HPLC Tubing polished?

The ends of the pre-cut SS tubing are polished. They have flat, burr free ends and a clean finish. Click HERE for High Pressure HPLC Tubing Ordering Information including SS tubing. © Copyright MicroSolv…

3 Calculating the internal volume of tubing

To calculate the internal volume (V), you need to know the length of tubing (L) and the inner diameter (ID). You then use the formula for volume of a cylinder. Convert L and ID into cm first. (1 inch…

4 Can I use the Flanging Tool for PEEK tubing?

The "Flanging Tool" (MicroSolv cat# 45099-001) or Kit (cat# 45099-002) is designed for use with relatively soft tubing that is used with low pressure. It can be used for FEP, ETFE, PFA, or PTFE tubing.…

5 Can the MicroSolv Super-T PEEK tubing items be used in medical applications?

In general, PEEK is FDA-approved as a long term implantent and can be sterilized. This refers only to the natural type of PEEK tubing and does not include tubing with stripes or markings. The dashed stripes…

6 Do you offer a low-adsorption tubing suitable for proteins?

The closest tubing we recommend would be FEP or PTFE. PTFE has micro-pores, and proteins may ‘creep’ in there. FEP is preferred because it has the same chemical stability but without the micro-pores.…

7 How is pressure inside tubing calculated for HPLC?

We have a useful Pressure Calculator on our website in which you determine the contribution your tubing ID will bring to the overall back pressure in your system. This can be handy when you are setting…

8 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…

9 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…

10 Maximum Pressure Chart for Stainless Steel Tubing

Below is a chart for the suggested maximum pressure that our stainless steel tubing can withstand under use in HPLC. MTC part no. O.D. (in.) I.D. (in.) I.D. Tolerance (in.) Length (cm) Max. Pressure (psi)…

11 Sample Loops

Sample Loops are available in a variety of internal volumes. Some of these will have several turns of the loop but others will not have a loop at all. In the latter case, the reason is because the tubing…

12 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…

13 Specifications of different stainless steel grades

Cogent™ HPLC column hardware is stainless steel T1 grade, AISI 316 LC type. HPLC system tubing is AISI 316, T2 grade. Elemental assays of the various stainless steel grades are given in the following…

14 Tips on cutting stainless steel tubing

Cutting stainless steel tubing for HPLC can be challenging. Here are some tips and instructions on cutting tubing using the MicroSolv tubing cutter, Catalog number 46001-01. Introduce the tubing into…

15 What does 316 in 316 stainless steel mean?

"316" or "Grade 316" is a class of stainless steel (SS) used by the steel industry to define a specific quality; it is the grade of steel which MicroSolv offers in our laboratory tubing, fittings and…
