How Can You Repair an MKS 1179A Mass Flow Controller?

AI Thread Summary
The discussion centers on the challenges of repairing an MKS Instruments 1179A Mass Flow Controller, particularly the difficulty in sourcing replacement parts. The user has disassembled the device and is seeking information about a specific component that includes a small stainless steel capillary tube and a ribbon cable with three wires. The device is out of warranty, and the user expresses frustration over the apparent lack of available repair parts, suggesting that MKS may prioritize servicing their own products to drive profit. There is a call for insights from others who have experience with repairing this model, highlighting a broader concern about the accessibility of replacement parts for such specialized equipment.

Would love to talk to anyonw that is familiar with MKS instruments 1179A Mass Flow controllers. I have taken apart a MKS mass flow controller and am trying to fix it but I am not sure where to get replacement parts, or even what some of the parts do.Most specifically is a small block on top of the main control block that has a very small diameter stainless stell capillary tube and an electronic ribbon with 3 wires in it. It is out of warranty so all I know is that it doesn't work and I would like it to. But this is really more of a learning experience than anything so that I can see how these controllers work. It mainly looks like the company would like to work on their own products and that there is not a lot of replacement parts available as far as I can see. Would appreciate any help from someone who has done this before.
 
I am having a hard time finding any repair parts for a MKS 1179A mass fow controller. I think that the company is trying to make money by not selling repair parts. Has anybody else had the same experience?
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
