We are #1. We are eBay's #1 quartz cuvettes superstore and one of the largest online quartz/glass retailers. We are a reputable scientific instrument company, established on 1970s and selling cuvettes online 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. Never buy serious scientific cuvettes from non-professional sellers. There are lots of eBay individual sellers who sell low quality cuvettes. They buy low quality cuvettes from unknown companies and sell it in the way of selling candy bars 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 kids but definitely not suitable for serious scientific R&D.4. Drawback of low quality cuvettes. Inaccurate light path, bad optical quality, fluorescence impurities, leakage, short cuvette life time and no professional helpThree major techniques of quartz cuvette manufacturing1. 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 under 50 USD are made with is method.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 cuvettes".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.Payment:We accept PayPal and ship orders to a PayPal Confirmed Address.
