The Knitted Reactor Coils are especially designed to fit into the Post Column Photolytic Reactor (cat# 49900-01) and their material of construction (PTFE) is transparent to the 254 nm UV light. Bubble formation in the coil should not occur due to backpressure from the system and prior degassing.

Are there any solvents that I cannot use with the knitted reactor coils (KRC) and knitted delay tubes (KDT)?
Yes, you cannot use any perfluorinated solvents or any solvent not compatible with PTFE with the KRC and KDT. Click here for ordering information for the post column reactor
The unit typically generates around 600 psi, which of course can varying depending on solvent viscosity and so forth. Therefore, the unit is fully compatible with a standard HPLC pump. Knitted PTFE Tubing Ordering Information
Yes, you can use one of the MicroSolv HPLC Column Water Jackets and pump heated or cooled liquid through it. The maximum temperature that the KRC or KDT can withstand is 200°C Click here for ordering information for the post column reactor
Do you have suggestions for a knitted reactor coils with a volume of 0.375ml with an internal diameter of 0.5mm?
A 1 meter long coil with 0.5 mm ID has a volume of 196 µl. therefore you would need 1.9 meter long coil. As we do not offer a reaction coil with such length needed for 375µl volume, I suggest you purchase 8 meters of PTFE tubing with 0.2 mm ID (MTC catalog number 49210-20) and […]
The reaction time can be changed by changing the inner diameter and length of the KRC. Click here for ordering information for the post column reactor
According to the International Journal of Mass Spectrometry, Knitted Delay Tubes can be used in the following manner with mass directed prep chromatography: Due to the low flow reaching the MS after the splitter relative to the high flow directed towards the collector or waste, a delay tube is placed between the prep UV and […]
I have been using the photochemical reactor for HPLC for a while now. Is there a decrease in the pressure rating of the KRC?
Yes, with long term or constant use there is a natural decrease in the pressure rating and the knitted reactor coil should be replaced. Click here for ordering information for the post column reactor
No, you can select from one of 1 many coils that will be completely compatible with the photochemical reactor. They vary in length and ID. See link below. Click here for ordering information for the post column reactor

What is the best way to attach the inlet of the knitted reactor coil tubing to the outlet of a tee with a PEEK finger tight fitting that will hold high back pressure?
Confirm that there is not an impediment to reasonable flow through the tubing which could increase the back pressure. We recommend using our items 47320-30 and 47320-34 which are High pressure Male nuts and ferrules.
What is the pressure rating of the knitted reactor coils (KRC) used with the HPLC post column reactor?
The knitted reactor coils are rated to hold 300 psig. After time and extended use, this rating may be significantly reduced. Click here for ordering Information for the post column reactor
What maximum flow rate can I use for a PTFE, 10m, 0.75mm ID Knitted Reactor Coil (KRC) with isopropanol?
Question: I am using a PTFE Knitted Reactor Coil (KRC) with 10m length and 0.75mm ID with isopropanol as the fluid I am pumping. What is the maximum flow rate I can use under these conditions? Answer: At ambient temperature, you should operate at no more than 10mL/min with isopropanol in order to stay within the […]
What tubing is suitable for use in a knitted reactor coil system featuring isopropanol, concentrated HCl, concentrated NaOH, copper, and luminol?
Alcohols such as isopropanol, acids such as concentrated HCL,bases such as concentrated NaOH, minerals such as copper and reagents such as luminol are chemically compatible with our PTFE, knitted reactor coils. The appropriate length, OD, and ID of the tubing will depend on the specifics of the application. More information about Knitted Reactor Coils, KRC
