reasons of ordering cuvettes from Science Outlet (eBay ID:
1. We are #1.
We are the eBay's #1 quartz cuvettes superstore and one
of the largest retailers on the Internet. Never buy serious scientific cuvettes
from other fly-by-night sellers who sell cuvettes as a side business. We are a
reputable scientific instrument company, established on 1970s and selling over
the internet since 2008 and on eBay since 2009. Just look at our eBay Feedback
record and you will see why our customers rave about our service.
2. We are Professional.
Currently we are the only professional quartz cuvettes
manufacture on eBay. We can design, label and manufacture quartz cuvettes and
other scientific lab wares for you.
3. How can you identify a non-professional
Just check their eBay lists, ask their questions
regarding optics and capability of build customized cuvettes. If they sell
toys, small electronics, know nothing about optics and making customized
cuvettes, they must be a non-professional store.
4. Market facts of Quartz cuvettes on eBay.
There are lots of eBay individual sellers who whole sell
low quality cuvettes with low price. However, they are not optical engineering
professionals and know nothing about the quartz cuvettes technology. They buy
low quality cuvettes from small companies and sell it on the way of selling a
candy bar or baby toys. These sellers could never use a spectrometer and know
nothing about spectroscopy, not to mention optical and material engineering. BTW,
they even steal cuvettes pictures and products descriptions from us. We believe
that low quality cuvettes might be good for high school kids but definitely not
suitable for serious scientific R&D.
5. Drawback of low quality cuvettes.
1) Windows material contains fluorescence impurities.
2) Light path is not accurate and bad optical quality.
3) Bond tech is not reliable and introducing leakage
4) Cuvette life time is short.
5) No professional help and warranty on optics, spectroscopy
and quartz cuvette applications.
major techniques of quartz cuvette manufacturing and quartz bonding:
1. Solder Frit Bonding Method: Glass frit is sandwiched between two surfaces and fused
at 800°C. The bonded surfaces are highly heat and chemical resistive. Low cost
with high quality. Most cuvettes on the market under $50 are made with is
2. Fully Fusion (Direct Fusion) Method: The process is direct fusion bonding without using any
adhesives. The bonded surfaces have superior optical surface quality and excellent
heat and chemical resistivity. All Hellma brand cells are made with this method.
All these kind of cuvettes we sell on eBay are called "Fully Fused
3. Photo sensitive adhesive Bonding Method: A bonding agent is activated or cured by Ultra-Violet
light. This method is very useful on bonding surfaces of different materials
such as glass, quartz and metal. Also, it is excellent on making cuvettes of
CaF, MgF and KBr which is very hard to do regular fusion work.
