Combi rack for various test tubes
This combination rack is made of polypropylene (PP) and has four sides with different hole sizes, making it suitable for several types of tubes in the laboratory. The rack can accommodate 4 tubes of 50 mL (Ø29 mm), 12 tubes of 15 mL (Ø16 mm), 32 tubes of 1.5/2 mL (Ø11 mm) or mini test tubes of 10–12 x 75 mm, as well as 32 PCR tubes of 0.5/0.2 mL (Ø7.5 mm). The color may vary from the image.

Chemistry
Compact spectroscope
Hand-held spectroscope in a metal housing, which allows qualitative observation of the spectrum from spectral lamps and other light sources.
This robust spectroscope is of very high optical quality and requires no adjustment. An optical grating with 600 lines per mm and a prismatic optical system ensures sharp spectra without distorted colours.

Physics
Conical pendulum
The uniform circular motion of the conical pendulum allows the following to be investigated: centripetal force vs radius of orbit, centripetal force vs orbital period and determination of g.The disc moves almost without friction on its ball bearing, while the bob’s angle with the vertical is read on the graduated, balanced disc.The pendulum’s length can be varied using four interchangeable wires with hooks.
