Question 1

Can different instruments be on different plans?

Accepted Answer

Yes, and most programs are structured that way. Put the instruments used for critical, regulated, or low-volume work on Platinum, the general research pool on Gold, and teaching or non-critical instruments on Silver. One asset register, one due-date schedule, three tiers of documentation.

Question 2

Which plan does an auditor expect to see?

Accepted Answer

It depends on the consequence of a volumetric error in your work. GLP/GMP, clinical, and quality-controlled environments should be on Platinum, where a detailed report and measurement uncertainty are available. Gold is defensible for most non-regulated but quality-conscious work. Silver is maintenance, not a documented calibration, and should be reserved for instruments whose results are not part of a regulated record.

Question 3

What is the difference between Gold and Platinum, in practice?

Accepted Answer

Gold measures at two points — high and low volume — with four measurements at each for single-channel instruments. Platinum measures at three points — low, mid, and high — with five measurements at each, and adds a detailed report plus measurement uncertainty on request. The mid-volume point is what catches linearity problems a two-point test misses entirely.

Question 4

Are multi-channel pipettes measured per channel?

Accepted Answer

Yes on Gold and Platinum. Gold takes 3 high-volume and 3 low-volume samples on every channel. Platinum takes 5 samples each at low, mid, and high volume. A multi-channel pipette is only as good as its worst tip, so a channel average would hide exactly the failure you need to find.

Question 5

How does the plan tier affect what a visit costs?

Accepted Answer

The plan tier sets the per-instrument price. A visit charge is then spread across the instruments serviced, which is why the cost per instrument falls as your count rises. Both are itemized on the quote before anything is scheduled.

Question 6

Can we change plans later?

Accepted Answer

Yes, at any point in the cycle. Programs commonly start on Gold, then move a subset up to Platinum once as-found trend data shows which instruments carry the most risk. Tell us at scheduling and we will apply the change from that service forward.
