BrandTech PMMA Macro or Semi-Micro Cuvettes
Reference:
Manufacturer: BrandTech
BRAND's plastic cuvettes are manufactured from the highest quality virgin resins for the highest optical quality and are an excellent choice for most spectrophotometry applications in the visible range. Manufactured from polystyrene (PS) or polymethyl methacrylate (PMMA), they provide accurate, reliable results. Choose PS for determinations above 340nm, and where cost is a concern. When performing assays above 300nm, choose PMMA. (For wavelengths below 300nm, see BRAND UV-cuvettes). These disposable cuvettes are available in macro and semi-micro sizes to accommodate most sample volumes and are compatible with most spectrophotometers and photometers. All BRAND cuvettes are manufactured from scratch-resistant materials and are grouped by manufacturing mold cavity number to ensure the lowest variation in extinction coefficient.

PMMA cuvettes are single-use sample cells for spectrophotometers and photometers. They are a good fit for routine colour reactions and protein assays read in the visible range, where you want to skip washing quartz or glass cells between samples.
Two sizes are offered: macro cuvettes for larger sample volumes, and semi-micro cuvettes when sample is limited. PMMA reaches a little further toward the UV than polystyrene, so it is the better choice when assay wavelengths sit close to that edge.
Being disposable, each sample gets a fresh cuvette, which avoids carryover between readings.

What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
