Why Strip Width Matters
Attogene offers two blue midstream cassettes with a lens in the same 140 x 15 mm body. The CO00016 is sized for 86 x 5 mm strips, while the CO00019 is sized for 4.5 mm strips. Choosing the housing that matches your strip width helps keep the strip seated and lined up with the result window, so pick the CO00019 if your cutter is set to 4.5 mm.
Typical Uses
- Handheld research tests built on narrow 4.5 mm strips
- Converting an existing 4.5 mm strip design to a midstream format without re-cutting
- Prototype and pilot lots that need a blue housing to identify the assay
- Small production runs before scaling up with a bulk order
Related Midstream Cassettes
The CO00020 pink cassette takes the same 86 x 4.5 mm strip in a 136 x 16 mm body with a lens, and the CO00015 does the same without a lens. For wider 6 mm strips, see the CO00017 green cassette. Compare every option on the lateral flow cassettes page.
Frequently Asked Questions
How is the CO00019 different from the CO00016?
Both are blue, both have a lens, and both measure 140 x 15 mm. The difference is the strip: the 86×4.5mm blue midstream cassette fits 4.5 mm wide strips, while the CO00016 fits 5 mm wide strips.
Will 5 mm or 6 mm strips fit this cassette?
The CO00019 is specified for 4.5 mm strips only. Use the CO00016 for 5 mm strips, or the CO00017 or CO00018 for 6 mm strips.
