You always need more airline tubing.

These Micro-Hematocrit Capillary Tubes are manufactured from soda lime glass, packed in plastic vials with reclosable snap-lock caps to maintain cleanliness.

Easily measure the cloudiness of a fluid.

VACUETTE® trace element tubes are designed to test trace elements such as aluminum, lead, cadmium, chrome, iron, fluoride, cobalt, copper, lithium, manganese, molybdenum, mercury, selenium, or thalium.

Made for scrubbing test tubes, culture tubes, and pipes.

Heavy duty tubes are durable, efficient, and designed to secure your goods. Includes snapping end caps that lock into place for maximum security

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

Will Not Scratch.

Investigate the spectral pattern of different gases.

Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.

Bulk rolls for easy length adjustment.

Gentle nylon test tube brushes.
