20pcs Sterile Syringe Filter, PES, 0.22 μm, 13mm, 1.3cm, HPLC, Individually Syringe Filter Parameters:
1. Filter characteristics: This filter can be mounted on a syringe. The filtering can be done by means of pushing the syringe without foreign pressure. The transparent high-polymer polypropylene material can be used for making the filter with high glossiness, small and dainty external form. In comparison with traditional filters, this filter has higher resistance to pressure . This filter has a good structure so as to insure wholeness of filter membrane and smoothly filtering. 2. Filter membrane material: It is made with imported Nylon 66 from U.K with better performances than that of Nylon 6. It has many characteristics such as hydrophily, high weak acid resistance, weak alkali resistance and thermo ability up to 80°C as well as good mechanical strength and foldable ability. This product is suitable to most organic and water solutions. |

Reasons
of ordering cuvettes from Science Outlet
(eBay
ID: quartzcrystal):
1. 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 help
Three major techniques of quartz cuvette manufacturing
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 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.
