Quick verdict
Hardware consumables can look similar at a glance while serving entirely different instrument needs. The key choice here is not simply a tube versus a larger lot: it is a decision between a specifically identified 500-micron ion transfer tube for a Thermo TSQ Quantum Access Max Triple Quadrupole Spectrometer and an assorted Thermo Fisher Vanquish UHPLC hardware lot.
Select the Thermo Fisher 70111-20972 Ion Transfer Tube when the 70111-20972 part number and TSQ Quantum Access Max target are central to the job. It is marked New and priced at USD 495.00. Select the Thermo Fisher UHPLC System Vanquish Consumables Hardware Assorted Lot when your focus is Vanquish UHPLC hardware in an assorted-lot format; it is marked New - Open box and priced at USD 699.99. The price spread is USD 204.99.

Where each option fits best
Thermo Fisher 70111-20972 Ion Transfer Tube wins for a defined TSQ component need
The 70111-20972 is the more focused choice. Its title, model, and intended discipline align around an Ion Transfer Tube 500-Micron Capillary for the Thermo TSQ Quantum Access Max Triple Quadrupole Spectrometer. The description also identifies its role at the atmosphere-to-vacuum gap in an atmospheric pressure ionization source. That specificity makes it the straightforward direction when the work calls for this named component and part number.
Thermo Fisher Vanquish Assorted Lot wins for Vanquish-oriented assortment scope
The Vanquish option is oriented around a broader collection: its model is explicitly an UHPLC System Vanquish consumables hardware assorted lot, and its MPN is VANQUISH. This makes it the better-aligned direction for someone seeking hardware consumables associated with the Vanquish UHPLC system rather than one named TSQ Quantum ion transfer tube. Its New - Open box condition is also distinct from the New condition attached to the 70111-20972 tube.
Product notes
NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum
Choose this component for a tightly defined TSQ Quantum Access Max requirement. It identifies the manufacturer as Thermo Scientific, gives the 70111-20972 MPN, and names the 0.50 mm, or 500-micron, inner diameter in the description. The instrument target is unusually specific: Thermo TSQ Quantum Access Max Triple Quadrupole Spectrometer. For a purchaser matching a named ion transfer tube rather than building around an assorted collection, those identifiers are the main advantage. It is also described as New and in an original case. Its limitation is equally clear: this is a focused ion transfer tube for the stated TSQ Quantum Access Max application, not a Vanquish UHPLC consumables hardware assortment.
THERMO FISCHER UHPLC SYSTEM VANQUISH CONSUMABLES HARDWARE ASSORTED LOT
The reason to select this choice is its Vanquish-centered assortment format. Its title and model both identify an UHPLC System Vanquish consumables hardware assorted lot, while the VANQUISH MPN provides a concise system reference. That framing suits a requirement centered on Vanquish-associated hardware consumables rather than a single, named 500-micron ion transfer capillary. The condition is New - Open box, and the merchant name is JW-iCuzATA. The tradeoff is focus: the product is presented as an assorted Vanquish lot, rather than as the specifically identified 70111-20972 Ion Transfer Tube for the TSQ Quantum Access Max. Choose it when the broader Vanquish lot designation is the deciding factor.
Final choice by use case
- For the Thermo TSQ Quantum Access Max and MPN 70111-20972: choose the Thermo Fisher Ion Transfer Tube 500-Micron Capillary.
- For a Thermo Fisher UHPLC System Vanquish hardware assortment: choose the Vanquish Consumables Hardware Assorted Lot.
- For a New condition item with a named 500-micron capillary role: the Ion Transfer Tube is the more direct fit.
- For a New - Open box Vanquish-oriented assorted format: the Vanquish lot matches that narrower use case.
