Rated on paperwork, packing and turnaround

Documentation

Certificate matched the vial without me having to ask

The lot on the label matched the certificate in the archive, and the endotoxin figure was already on the document rather than something I had to email for. That sounds like a low bar. Two of the four suppliers we evaluated last year could not clear it.

Documentation

They publish their held lots

I went looking for the quarantined lot after a colleague mentioned it and found the full certificate still in the archive, marked as held, with the reason written out. Publishing a failure is the only part of a quality claim that costs anything, so it is the only part I read as evidence.

Shipping

Cold chain held, packaging is over-engineered

Arrived on the second morning with the gel packs still firm and the temperature indicator unbroken. My only note is that unpacking generates a genuinely absurd volume of foam for two vials. Our waste stream noticed.

Ordering

Purchase order went through without a phone call

Our accounts team needs an itemised quote with catalogue numbers before anything gets approved. The order sheet exported exactly that, including the lot numbers, so it went through procurement on the first pass. First time this year.

Documentation

Kit components stayed individually traceable

The kit shipped with both component certificates rather than one averaged summary sheet. That distinction matters when an auditor asks which lot went into which experiment, and most suppliers get it wrong.

Support

Straight answer about recovery losses

Asked about adsorption on untreated plasticware and got a reply describing what the gravimetric fill figure does and does not tell me. They also said plainly that they would not advise on my protocol, which I would rather hear than a guess.

Documentation

Gradient conditions were actually on the certificate

The certificate lists the column, the gradient and the detection wavelength. I reproduced their separation on our own instrument and landed within a tenth of a percent of the released figure. A purity number without the method behind it is not a number.

Shipping

Customs paperwork was correct the first time

Research-use declaration and the commercial invoice both matched what our import broker needed. Cleared in a day and a half. The previous supplier we used cost us three weeks and a re-order because of one wrong line on a form.

Ordering

The label and log pairing solved a real problem

Students were aliquoting into unlabelled tubes and then guessing. The pre-numbered labels with matching log rows fixed it in one term. Not glamorous, and the single most useful thing we have bought this year.

Shipping

Slower than quoted, but they flagged it first

Quoted four days, took nine. The difference is that I heard about the delay from them before I noticed it myself, with the new tracking reference attached. Marking this three because it was late, not because of how it was handled.

Support

Would not speculate, and said so

I asked a question that was really about application rather than material, and the reply said support cannot advise on protocol or use and pointed me back to the certificate and the release date. Correct answer. I have had suppliers cheerfully invent one.

Documentation

Even the consumables carry a certificate

Did not expect a carton of filters to arrive with a bubble-point record. It meant that when a separation looked wrong I could rule the filter out in about a minute instead of an afternoon.
