"tube+coolers"

For use in specimen collection, wound care, application of topical dressings, cosmetic applications/tattoos, or general purpose

Insert a sugar solution into the 16" clear tube, lower the membrane end into the jar of water, and watch the water level rise.

Digital dry baths that include timed or continuous operations and a removable hinged lid. External temperature probe can be positioned directly inside a sample tube.

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.

Organic liquid thermometer features a U-shaped tube mounted on a plastic casing with metal floats at the top of each column.

Pre-calibrated test tubes and labware give fast, accurate results in the classroom or in the lab.

These foam plugs are designed to fit most test tubes and vials.

Nose cone variety pack for Estes BT-50 rocket body tubes.

Generate a uniform magnetic field perpendicular to the axis of the Teltron D series tubes.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

The HOBO® water Level data logger features high accuracy at a great price and ease-of-use, with no cumbersome vent tubes or desiccants to maintain.

Freshwater. Unicellular; lunate. Proteose agar.

Characterized by green plastids and cell walls composed of cellulose.

Check valves allow one way passage of water or air through tubing.

This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.

Demonstrate the combining volume ratios of gases.

Pre-calibrated test tubes and labware give fast, accurate results in the classroom or in the lab.
