BrandTech Semi-Micro UV Cuvettes
Reference:
Manufacturer: BrandTech
Eliminate the need for cleaning, and the associated risk of sample carryover and cross-contamination. BRAND's UV-transparent, disposable cuvettes replace expensive, fragile quartz cuvettes and are excellent for DNA, RNA, and protein analysis between 230-900nm. Made from a proprietary polycyclical olefin, they can be used with most polar solvents, acids and alkaline solutions. In addition to the macro and semi-micro sizes, UV-cuvettes are available in ultra-micro sizes that require only 70µL of sample volume. The ultra-micro cuvettes are also available individually-wrapped and independently-certified DNA-, DNase-, RNase-free for an extra degree of sample protection. 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.

These UV-transparent cuvettes let you measure nucleic acids and proteins without quartz cells. Because they are disposable, there is no washing between samples and no risk of a scratched or broken quartz cell spoiling a reading.
The semi-micro size needs a minimum fill of 1.5mL, a good middle ground between the macro size at 2.5mL and the ultra-micro size at 70µL. They are a practical choice for checking DNA purity and concentration before PCR or sequencing.
They handle most polar solvents, acids and alkaline solutions used in sample buffers.

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.
