Let us begin with enrolling in a second to consider the following scenario: Ah, moment to begin a task in a brand new laboratory. Different procedures, new equipment, new colleagues and best of all the new glass cuvettes to make use of! Wait however these cells aren’t marked… Is it a glass cuvette or maybe a quartz cuvette?
We get calls this way all the time from individuals attempting to determine the cuvette material that they’re using. A great deal of time the discussion goes something as this:
FFS: Hello
Researcher: Hello I merely started only at that brand new laboratory also I believe I’ve a glass cuvette but there’s absolutely no box or even labeling on it.
FFS: Are there any markings on the cuvette?
Researcher: These cuvettes appear to be quite old, so perhaps it wore off.
FFS: No problems we are able to enable you to figure it out there!
And that’s precisely what this article is approximately. Why don’t we go over closely regarding how to determine exactly how to recognize what material a cuvette is created out of.
Today most cuvettes, except for plastic material, look the same. By visually taking a look at a cuvette it’s not possible to make sure whether the content is optical glass, UV quartz, or maybe IR quartz. What we do here’s we mark all the various materials on the cuvette. Therefore in case you purchase a glass cuvette from us, you are going to receive a cellular marked “G” for optical “P” or glass for Pyrex glass. UV quartz cuvettes will likely be marked with a “UV” as well as IR cells is marked with, big shock right here, “IR” letters.
How you can Tell If You’ve a cup Cuvette
Ok so your cuvette hasn’t letters, corresponding numbers, or maybe any type of identification marks. They best thing to perform to find out if it is a quartz or maybe glass cuvette is usually to pop it in to the spectrophotometer of yours and operate a wavelength scan from 200 700 nm.
If you notice transmission beginning at 190 nm this’s a UV quartz cuvette.
If the transmission begins at 340 nm this’s a glass cuvette.
If transmission begins at 220 nm this’s an IR quartz cuvette.
The real difference between Quartz plus Glass Cuvettes
This is the very best method to determine what material an unfamiliar cuvette is created out of. Some other differences between quartz and also glass cuvettes are the following:
Transmission properties – because you are able to see through the info above quartz has a larger transmission range compared to glass.
Thermal Properties – A quartz content has a substantially larger melting point compared to glass.
Chemical Compatibility – The substance structure of quartz is better compared to glass which makes it capable to deal with a larger variety of chemical substances that could melt or even harm a glass cuvette.
Modifications – Here’s where glass cuvettes truly shine. A pyrex cuvette is quite simple to alter and also make attachments to. Quartz cuvettes could be customized but is a much larger process.
If you’ve some cuvettes available you need help identifying, provide us a call or maybe you are able to send them to the lab of ours for analysis.
Here is to the success of yours!
