20 Glass Buckets, Test Tubes For Use With Spectrophotometer Spectronic 20
Then set the needle to zero before replacing the control solution with your sample. After 10 seconds, read the percentage values and write them down before unpacking the sample. AVOID SPILLS – USE BUCKET CAPS Samples are placed in standard 4.5ml buckets with a 10mm light path. Organic solvents, in particular propanone, should only be used with glass buckets or test tubes.
Product numbers N201 and N205 are recommended for use as reaction tubes in gelstillation tests. Culture tubes are used for tissue culture and blood banks and are often disposable. Although they are usually supplied as plastic test tubes with lids, they are also available in glass.

It saves me a lot of time and saved me from breaking several tubes and buckets. Historically, reusable quartz veins were needed for measurements in the ultraviolet range, as glass and most plastics absorb ultraviolet light, causing interference. Today, there are disposable plastic buckets made of specialized plastics that are transparent to ultraviolet light. Glass, plastic and quartz submers are suitable for measurements at longer wavelengths, such as in the range of visible light.
Designed with top and bottom holders to keep containers upright and safe, and a lip to hold spilled liquid. Used with a sip accessory, they make it possible to measure controlled sample volumes. Flow cells are ideal for reducing sample processing for measuring toxic materials and for monitoring continuous production processes. It is used for highly diluted samples often for environmental testing applications. These range from 40mm, 50mm to 100mm in Biochrom instruments.
