Selecting hardware consumables is less about finding a broadly similar part and more about matching the exact instrument or part reference. Here, the decision is clear: the Thermo Scientific component is an ion transfer tube identified for the Thermo TSQ Quantum Access Max Triple Quadrupole Mass Spectrometer, while the Shimadzu option is a hardware consumables kit identified by part number 228-43969-91. Their prices and conditions also point to different purchasing situations.
Quick verdict
Choose the NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum when the job specifically calls for a 500-micron ion transfer tube for a Thermo TSQ Quantum Access Max system. Its stated 0.50 mm inner diameter and dedicated instrument application make it the more targeted selection.
Choose the Shimadzu 228-43969-91 Hardware CONSUMABLES Kit 460-08782 REV.E when the required reference is Shimadzu part number 228-43969-91 and an open-box hardware consumables kit fits the requirement. It carries the lower price of the two options.
At-a-glance comparison
| Detail | Thermo Fisher 70111-20972 Ion Transfer Tube | Shimadzu 228-43969-91 Hardware CONSUMABLES Kit |
|---|---|---|
| Price | USD 495.00 | USD 79.99 |
| Brand | Thermo Scientific | Shimadzu |
| Condition | New | New - Open box |
| Identified type | Ion Transfer Tube 500-Micron Capillary | Hardware CONSUMABLES Kit |
| Key identifier | MPN 70111-20972 | MPN 228-43969-91 |
| Country of origin | United States | Japan |
The USD 415.01 spread is substantial, but the two entries are not interchangeable on name alone: one is a specific ion transfer tube and the other is a Shimadzu hardware consumables kit.
Where each product wins
Thermo Fisher 70111-20972 Ion Transfer Tube
The Thermo Scientific tube is the direct choice for work centered on the named TSQ Quantum Access Max Triple Quadrupole Mass Spectrometer. The title and description identify a 500-micron capillary, while the description also specifies a 0.50 mm inner diameter. That degree of application and component specificity is useful when replacing an ion transfer tube rather than sourcing a broader consumables kit. Its new condition is another straightforward match for buyers who need that stated condition.
Shimadzu 228-43969-91 Hardware CONSUMABLES Kit
The Shimadzu kit wins on price and part-number alignment for shoppers seeking 228-43969-91. At USD 79.99, it sits well below the Thermo component's USD 495.00 price. The REV.E designation in the title gives the kit another useful identifier for a requirement that calls for that revision. Merchant JW-iCuzATA is associated with this Shimadzu option.
Product notes
NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum
Pick the Thermo Scientific ion transfer tube when the required hardware is explicitly a 70111-20972 500-micron capillary for a Thermo TSQ Quantum Access Max Triple Quadrupole Mass Spectrometer. The component is described as bridging the atmosphere-to-vacuum gap in an atmospheric pressure ionization source, and its 0.50 mm inner diameter further identifies the intended tube format. The new condition supports a purchase requirement centered on a new component. The trade-off is the USD 495.00 price, and the narrow TSQ Quantum Access Max application means it is best reserved for that named instrument context rather than chosen simply because a general hardware consumable is needed.
Shimadzu 228-43969-91 Hardware CONSUMABLES Kit 460-08782 REV.E
The Shimadzu hardware consumables kit makes sense when 228-43969-91 is the needed part number and the REV.E reference matches the requirement. At USD 79.99, it is the lower-priced selection in this head-to-head. The Shimadzu name, Japanese country of origin, and hardware consumables kit model give shoppers several identifiers to align with an existing requirement. Its limitation is the stated New - Open box condition, which differs from the new condition assigned to the Thermo ion transfer tube. It is also a kit rather than the specifically named 500-micron ion transfer tube, so the part category should drive the decision before price does.
Final choice by use case
For a Thermo TSQ Quantum Access Max requirement involving a 500-micron ion transfer tube, select the Thermo Fisher 70111-20972 Ion Transfer Tube. For a requirement centered on Shimadzu MPN 228-43969-91 and REV.E, select the Shimadzu Hardware CONSUMABLES Kit. Start with the instrument or part number, then use the USD 415.01 price spread and stated condition to settle the final choice.
