We optimize scientific innovation and manufacturing technology to enable our customers to serve their patients and consumers. Pyrogenic-free borosilicate glass test tubes, 10x75mm, with 50/hpg lid. All test tubes are made of USP TYPE 1 flint borosilicate glass. Product number N207 is recommended for dilution of endotoxin standards and test samples for all endotoxin detection tests.
Acuvette is a tubular device with two straight sides and two round or straight sides. It also has one end that is sealed and the other end that is open. Plastic, glass, molten quartz and other materials are examples.
As the needs of our customers have evolved, so have our capabilities. We have become experts in scientific operations, improving performance with advanced solutions and providing guidance on best practices. We have built our reputation for consistent, comprehensive control of day-to-day operations, enabling laboratory, clinical and manufacturing environments to focus their high-quality resources on core scientific priorities.
The duration of a sample can be omitted, changes with different solvents. If I were measuring on something like a plate of 96 wells, I wouldn’t wait an hour simply because of the environmental factors that affect such a small sample size. While it can technically be measured after such a long time, I would personally question the validity of any result obtained that way.
Quartz excels at emitting UV light and can be used for wavelengths ranging from 190 to 2500 nm. Plastic buckets are often used in rapid spectroscopic tests, where high speed is more important than high accuracy. Plastic buckets with a usable wavelength range of 380-780 nm can be disposed of after use, preventing contamination by reuse. Disposable buckets can be used in some laboratories where the beam light is not high enough to affect absorption tolerance and value consistency.
Disposable plastic UV: These are usually low-volume 70L cells, made of special plastic for UV life sciences applications, such as nucleic acid measurements. Single-use plastics: There is a wide range of plastic cells that are suitable for a variety of applications. Carefully monitor both the application and the spectral range of the cell. In addition, there are also fittings such as a pipe rack for safer storage. Since the test tubes used must contain solutions, this helps prevent breakage and spillage. The frames can be supplied in stainless steel, which is corrosion resistant.
Most spectrophotometers need to be heated before they can give an accurate measurement. Turn on the device and leave it for at least 15 minutes before taking samples. Email updates I am interested in receiving updates about Lonza’s products and services by email, post or phone.
