When you need hardware consumables, the real decision comes down to what you are trying to keep running. A mass spectrometer demands a precision capillary that fits a specific instrument, while a TIG torch needs a collection of cups, collets, and seals that you can swap out before the next weld. The four options here cover both worlds with listed prices from $22.96 to $699.99, a spread of $677.03. One is a single lab part, one is an open-box assortment, and two are torch accessory kits. Your job is to pick the set that matches the tool on your bench.
Quick Take
- If you need a capillary for a Thermo TSQ Quantum Access Max triple quadrupole mass spectrometer, the NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary is the specific listed option at $495.00.
- If you want a broad collection of Vanquish UHPLC consumables and hardware, the THERMO FISCHER UHPLC SYSTEM VANQUISH CONSUMABLES HARDWARE ASSORTED LOT is the largest listed set at $699.99.
- For garage or home TIG torch upkeep, the 23 Pieces TIG Torch Accessory Kit at $47.89 gives you more pieces for WP-17, WP-18, and WP-26 torches.
- If you only need the basics, the 12 Pieces TIG Metal Joining Torch Consumables Kit Ceramic Hardware Reliable is the lowest listed price at $22.96.

Product Notes
NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum
If your lab runs a Thermo Scientific TSQ Quantum Access Max triple quadrupole mass spectrometer, this part is listed specifically for that interface. The 500-micron capillary design is the kind of precise hardware consumable that keeps the atmospheric pressure ionization source connected to the vacuum region, and it is sold as new with the Thermo Fisher part number 70111-20972. The listed price is $495.00, which reflects a single dedicated component rather than a multi-piece kit. The clear limitation is scope: this is one capillary tube, so it will not help with broader consumable needs like fittings or columns. For a lab that just needs this exact tube, the specificity is exactly what you want.
THERMO FISCHER UHPLC SYSTEM VANQUISH CONSUMABLES HARDWARE ASSORTED LOT
This is the broadest option in the comparison. Listed at $699.99, the THERMO FISCHER UHPLC SYSTEM VANQUISH CONSUMABLES HARDWARE ASSORTED LOT is a new open-box collection from merchant JW-iCuzATA. The Vanquish model label tells you it is aimed at UHPLC system upkeep, and the assortment includes whatever hardware and consumables are shown in the listing photos. That makes it a good choice when you need a variety of parts rather than a single replacement component. The trade-off is that an assortment lot is not a sorted, itemized kit, so you should check the pictured contents to see whether they match your current inventory. It is also the highest listed price here, so reserve it for projects where a mixed batch is useful.
23 Pieces TIG Torch Accessory Kit Unobstructed Hardware Sturdy for Home Garages
For TIG torch maintenance, this kit brings 23 pieces to the table at $47.89. The components are designed for WP-17, WP-18, and WP-26 torches and include clear cylindrical glass cups, brass threaded fittings with red shield sleeves, black torch components, copper-colored tubes, green sealing rings, and white insulating rings. That range makes it a solid choice for a garage or home setup where you want spares for several common torch models. The strength is count and variety: you get a more complete assortment of cups, seals, and fittings. The limitation is that the kit is still a consumable refresh pack, not a replacement torch head, so you need a compatible WP-17, WP-18, or WP-26 torch already. It also comes from a China-origin listing with no brand name attached.
12 Pieces TIG Metal Joining Torch Consumables Kit Ceramic Hardware Reliable
At $22.96, this 12-piece kit is the lowest listed price in the comparison. It is also made for WP-17, WP-18, and WP-26 torches, but it takes a more streamlined approach. The set includes lavender ceramic cups marked 4, 5, and 6, a copper collet body with a red shielding cap, a clear cup, a black torch cap, a white insulating sealing gasket, and four green sealing rings. The materials mix of metal, ceramic, synthetic material, and rubber is built for heat and regular joining work. Its strength is the compact, no-extras set at a low entry price. The limitation is fewer total pieces than the 23-piece kit, so you will have less redundancy for long projects or multiple torch setups.
Final Recommendation by Use Case
Choose the NEW Thermo Fisher 70111-20972 Ion Transfer Tube if your immediate task is a mass spec capillary replacement and you know your instrument is the TSQ Quantum Access Max. Choose the THERMO FISCHER UHPLC SYSTEM VANQUISH CONSUMABLES HARDWARE ASSORTED LOT if you want a large, open-box mix of Vanquish UHPLC parts and are comfortable reviewing the pictured contents. For TIG torch owners, the 23 Pieces TIG Torch Accessory Kit is the better pick when you want more spare cups and fittings for WP-17, WP-18, or WP-26 torches. If you just need the core consumables at the lowest listed price, the 12 Pieces TIG Metal Joining Torch Consumables Kit covers the essentials without going overboard.
