Buying guide: Check out before choosing

Now as you have already gone through the top-quality cuvettes above, you need to know what basic things you need to consider before buying.

  • Decide whether disposable or reusable cuvette is ideal for you.
  • Look for regulation-size cuvettes.
  • You should check out the usability.
  • The number of polished windows does matter.
  • If it has an open-top type design, look for the lid.

We are not done here because a new buyer will still find it tough for him to choose an ideal cuvette or cuvette package. So let’s go deep into the above things.

Disposable or reusable

The quality, structure, and usability depend largely on deciding whether you need disposable or reusable cuvettes. Disposable cuvettes are one-time usable, and they are mainly made of plastic. However, reusable cuvettes come with quality quartz glass construction.

Manufacturers mostly choose polystyrene for disposable cuvettes. Another big difference between these two types is that the first comes in a package, whereas the second one can come in a single piece.

Cuvette size

The ideal size of a cuvette is 45 mm tall, 12.5 mm long and 12.5 mm wide. It is the perfect size to make the cuvette usable in any lab application. Also, for spectrophotometers, this size is regarded as the ideal one. Regardless of the size, the design and usability of the cuvettes can differ.

Polished and frosted windows

In terms of polished or transparent windows, there are mainly two types of cuvettes. One has two polished windows, and the other one has four polished. You have to choose one of these designs depending on your lab work.

Cuvettes with two polished windows also have two frosted windows. But the frosted window is completely absent in the other type of cuvettes. However, having frosted windows doesn't mean there will be a slight problem in emitting light from the source.

Applications

Both disposable and reusable cuvettes are appropriate for lab usage, but disposable ones aren’t a good option for the spectrophotometer. These cuvettes typically aren't usable when the wavelength is less than 300 nm or it goes to UV-Vis spectrophotometer.

However, quartz or reusable cuvettes are made to be used on spectrophotometers and photometers. Most of these cuvettes fit on UV-VIS-NIR fluorescence spectrophotometers. It means if the purpose is to work with a spectrophotometer, you better choose quartz cuvettes.

Wavelength

Most quartz cuvettes have a wavelength that ranges from 190 nm to 2500 nm, which makes them usable in UV-Vis spectrophotometers. However, some of these cuvettes also offer a range of 340 nm to 2500 nm. Disposable or polystyrene cuvettes are not usable when the wavelength is less than 300 nm.

Holding volume

The ideal holding volume of a cuvette is 3.5 ml. However, it ranges from 2.5 ml to 4.5 in both disposable and reusable cuvettes. In some rare models, you will find the capacity is only between 0.35 ml to 0.7 ml.

Lid or cover

Most cuvettes come with an open-top type design, and it becomes necessary to have a cover or lid for this. A lid or cover will protect the solvent inside and also ensure safety while working in the lab. You will find either a Teflon lid or PTFE cover with the cuvettes.

Resistance

The functionality of a cuvette depends a lot on the heat resistance, and it should resist heat up to 600-degree Celsius. Moreover, the buyer must ensure the resistance from acid, base, and other chemical solutions.

When you work on lab or hospital you should must wear Isolation Gown for safety.

Knowing about different types of cuvettes

The types of cuvettes are defined by the materials used to make them. There are mainly four types according to the materials, plastic, glass, quartz, and sapphire.

  • Plastic cuvettes mostly have polystyrene construction. And it works within a visible wavelength that ranges from 380 to nm.
  • Glass cuvettes are for UV applications, which work within the wavelength range of 340 to 2500 nm.
  • There are UV quartz and IR quartz in quartz cuvettes. UV quartz cuvettes are used for wavelength below 380 nm, and the wavelength ranges 220 to 2500 nm for IR quartz cuvettes.
  • Sapphire is the most durable and expensive cuvette material, which has a wavelength ranging from 250 to 5,000 nm.

What are cuvettes used for

The main purpose of a cuvette is to hold the solution, which is going to be analyzed. It is a plastic, glass, or quartz container that helps the application to measure the light absorbed by this solution keeping it inside.

Except for the absorbance, you can also measure transmittance, fluorescence intensity, fluorescence polarization, or timing of the solution using a spectrophotometer.

How much do cuvettes cost?

Before talking about the cost, you need to know whether it is a single product or a package. Typically, a single cuvette can cost you around $20 to $80, where plastic cuvettes are cheap than glass or quartz. However, buying two or four cuvettes packages can increase the cost up to $110 as well.

FAQs

What type of cuvette do I need for a spectrophotometer?

Glass or quartz cuvettes are the ideal choices for spectrophotometers.

What is the light path of a cuvette?

The light path length of a cuvette is 10 mm in general. However, it can vary from 1 mm to 100 mm as well.

How many volumes of cuvettes are available there?

There are macro, semi-macro, micro, sub-micro, and ultra-micro cuvettes available as cuvettes volume.

What are the most common materials used to make cuvette covers?

PTFE, Teflon, and silicon are the common materials used to make cuvette covers.

Are cuvettes reusable?

Through proper cleaning after usage, a glass or quartz cuvette is reusable around ten times.

How should one hold a cuvette?

Any user should hold a cuvette wearing powder-free gloves that don't hamper the clarity of the polished surfaces.

How much should you fill the cuvette with the solution?

You should fill about ¾ part of a cuvette with the solution for testing.

If you have long lab works to do, you should better look for quality cuvettes like glass or quartz. However, plastic cuvettes can save you from cleaning them every time. Now decide which one you need.
