Diagnostic Consumables
Reaction Cup
Molded reaction cups for automated analysers, where the optical path runs through the wall and a thickness variation reads as a result error.
Product Overview
What This Component Is
Molded reaction cups for automated analysers, where the optical path runs through the wall and a thickness variation reads as a result error. This part has been in our catalogue since the original site, and it is a good example of why the tool matters more than the machine.
Key Benefits
- Wall section controlled so the optical read path stays consistent
- Cavity finish cut for clarity rather than polished until it looks acceptable
- Automated molding cells sized for analyser consumable volumes
Molded on tooling we cut ourselves in Shenzhen. Certification covers the site doing the work: ISO 9001:2015 and ISO 13485:2016.
Who It Is For
- IVD analyser manufacturers
- Reagent kit assemblers
- Laboratory consumable brands
Problems It Solves
- Read errors traced back to wall thickness variation
- Cups that stack or jam in the analyser feeder
- Clarity that varies between cavities on a multi cavity tool
Application Scenarios
- Automated analyser reaction wells
- Photometric and turbidimetric reads
- Reagent incubation steps
Technical Features
How It Is Engineered
- Even wall section maintained through the read zone
- Cavity surface finish specified for optical clarity
- Stack and feed geometry checked against your analyser during sampling
Materials
- Medical grade resin selected against your specification rather than substituted by us
- Customer nominated grades accepted where a device master record already fixes the material
- Colourants and additives confirmed in writing before the first sampling run

Manufacturing Process
- Mold design review
- Steel machining and EDM
- Mold trial and cavity sampling
- Clean room or conventional molding
- In process dimensional check
- Clean room packing
Quality Control
- Cavity by cavity dimensional sampling before a tool is released
- In process checks during the molding run rather than only at the end
- ERP system records the lot, tool and machine behind every shipment
Customization Options
- Cavitation sized to your annual forecast instead of a fixed standard tool
- Colour and resin grade to your specification
- Clean room packing format and labelling agreed before the first shipment
Comparison
Compared With Other Routes
| Generic laboratory cups | A generic cup is not toleranced for your feeder or your read path. Custom tooling lets both be designed in. |
|---|---|
| Sourcing cups without the tool | If you do not own the cavity you cannot correct a clarity problem. You can only change supplier and start again. |
Use Guide
How To Handle It
- Validate the read path on production moulded cups, not on prototypes
- Test feeder behaviour with a full carton rather than a handful
- Keep cups bagged and dry until loaded into the analyser
Questions Buyers Ask
Questions About Reaction Cup
Can you hold optical clarity across all cavities?
Clarity comes from cavity finish and packing control. We sample every cavity and compare them rather than assuming a good first shot represents the tool.
Do you test the cup in our analyser?
We cannot run your instrument here, but we will sample against your feeder drawing and send parts early so you can test them in the real machine before the tool is signed off.
What volumes can you support?
Our injection department runs automated molding cells alongside conventional ones. Send the annual forecast and we will size cavitation to it.

Water Tightness Validation On A Container And Closure Pair
A container and a closure can each pass dimensional inspection and still leak together, because the seal is a property of the pair and not of either part alone.
