Lifestyle Visions quartz cuvettes are made out of clear rich purity quartz materials to adapt to the needs of a variety of spectrophotometer laboratory studies. The cuvettes are acid and alkali resistant. Each quartz cuvette holds 3,500 of microliters. The cuvettes are Type 1 with two sides frosted and two sides polish. The heat resistant are able to withstand high temperature up to 600 ℃.  

These cuvettes have a standard 12.5 mm square outside dimension and a 10 mm light path through the sample. The es quartz cuvettes transmittance of light is above 83%. The Cuvette design allows the light beam to come through the front window and exit the back window of the cuvettes.

The highly transparent UV cuvettes require as little as a sample for accurate and precise quantitation of DNA, RNA, and proteins.

High Quality - Made of clear high purity quartz, it can be used in many labs and meets different needs.

Specification - The capacity of this cuvette quartz is 35ml. The height is 48mm. It has a 10mm light path through the sample. The transmittance of light for this quartz is over 81%.

Supplement - Due to the UV transparent cuvette fitting for most UV and visible spectroscopic assays, it can be a compliment for working with precious DNA or RNA samples.

Cuvettes Caps

Good for glass, quartz and Disposable Cuvettes

cap size: 10x10mm

Disposable standard and semi-micro cuvettes are designed for use in spectrophotometers

They are produced from either optical polystyrene or UV grade PMMA and include optical windows for optimum transmittance through spectrum range from 340 to 800nm for the optical polystyrene and from 280-800nm for the UV Grade PMMA

These cuvettes are engineered for high reproducibility and offer variations within the range of ±1% absorption; This is vital when batch analysis is being undertaken

Our fused quartz cuvettes are fused together by molecular forces at ultrahigh temperature without the use of any kinds of adhesives.

Acid, base, organic solvent-resistant. No leakage is found for these cuvettes containing hydrochloric acid, anhydrous ethanol, carbon tetrachloride, and benzene for at least 24 hours. Special attention needs to be made to chloroform, as the chloroform slowly etches the quartz surface by nature. 


The operating spectral range is 190-2500 nm for the maximum light transmittance and the operating temperature as high as 600°C / 1,112°F for these JGS1 optical quartz materials.

Material: Clear rich purity quartz materials,UV transmittance is above 80%.

Chemical-Resistant: Acid (except hydrofluoric acid), base, and organic solvent-resistant.

Heat-Resistant: 600°C/1112°F.

Manufactured from polystyrene (PS), provides accurate, reliable results, even at wavelengths as low as 300nm.

Accommodates most sample volumes, and is compatible with most spectrophotometers and photometers.

[±5% ACCURACY] The viscometer uses a graduated disk, and the viscosity values are measured by moving the rotor rotation through the spinneret and spindle, has a large viscosity measurement range 10-100,000cps and the measurement error: ±5%, give your enough resolution to control my processes better.

[ROTORS x ROTATION RATE] Different rotors (1,2,3,4) can be selected according to the viscosity range of different test liquids, and different speed (60,30,12,6) can be set. The knob adjustment is straightforward with a coefficient table on the top for easy reference. You can unlock more unknown liquid viscosity.

[LIGHT WEIGHT BUT PRACTIALl] The rotary viscometer is light in weight, easy to move and operate flexibly. The helical gear lifting system effectively ensures that the viscometer can move up and down easily without sliding down by itself, which ensures the smooth progress of your experiment.
