You're basically working with a phosphatidylcholine and deoxycholate formulation here, but the real application isn't what teh label suggests—it's a controlled solvent mixture for precision cleaning in electronics assembly, specifically for removing flux residues from tight-pitch BGA and QFN packages after reflow.
We've seen these 5*10ml vials used in R&D labs testing new solder paste formulations where standerd isopropanol leaves a film that interferes with impedance measurements, and at 99.5% purity by HPLC you're looking at less than 0.5% non-volatile residue after evaporation, which matters when you're dealing with sub-100nm line widths.
ROHS compliance means you've got restricted substance levels below 1000ppm for lead, mercury, cadmium, and hexavalent chromium—actually, the batch we shipped last week tested at 12ppm lead and undetectable levels for the others, but don't expect this to work for aqueous-based cleaning systems, it's strictly a solvent-phase process.
Storage is critical here—keep it between 15-25°C in the original aseptic packging, and you'll get about 18 months shelf life give or take, but we've had customers push it to 24 months with no degradation in dissolution performence when sealed properly.
10 sets is the MOQ, so you're looking at 50ml total for roughly $45-60 depending on shippng, and we usually have stock in Shenzhen ready to go in 2 business days, though confirmed lead time is worth checking if you're ordering over 10,000 units (about 8-12 days for that volume).
One thing most buyers don't ask about is the vial cap liner—we use PTFE-faced silicone septa that hold up to multiple needle punctures without coring, so if you're transferring via syringe into smaller aliquots, you won't get particulate contamination, which is a common issue with cheaper polypropylene liners.
We keep it low — you can start with as little as 1 pack of 5 vials. No need to commit to large volumes upfront.
Yes, we include the ROHS compliance doc with every order. Just let your sales rep know if you need it in a specific format.
Lead time is typically 7-10 business days after payment confirmation, depending on your location and shipping method.
Absolutely — each batch is tested for purity before filling. We can share the COA (Certificate of Analysis) upon request.
We offer customization on the outer packaging for larger MOQs. For the 5*10ml kit, standard disposable aseptic packaging applies unless agreed otherwise.
