Two-tier rack with thirteen 25mm holes, and six drying pins Solid hardwood construction Polished to minimize damage from spills

A Vigreux column is a type of air condenser where the simple tube has been modified to include an abundance of downward-pointing indentations. This dramatically increases the surface area per unit length of the condenser. Includes a 24/40 connector.

Operates on 1.5V or 3V DC. Speed: 7000-11000 RPM. Motor is 40 MM long x 20Mm in diameter. Shaft size: 2 MM diameter x 8 MM long.

These leak-proof, economical polypropylene stopcocks have a PTFE plug and serrated ports that accept tubing from 6mm to 10mm in diameter. 

Floating microtube racks are ideal for thawing, cooling, or incubating samples in water or ice baths at a wide range of temperatures from -70C to 100C.  Tubes are supported below the lip while conical ends are immersed in water.  Racks feature a handle for easy removal from water bath as...

The Advanced Projection Ripple Tank is a comprehensive system for demonstrating basic wave phenomena using water waves. A horizontal glass plate is mounted in a watertight frame with foam beaches around the perimeter to suppress unwanted wave reflections. This tank is mounted on three tall legs with...

This product effectively demonstrates the laws of reflection and refraction. The 16cm diameter acrylic water tank has a 360 degree scale and a moveable arm carrying a laser activated by a push-button. Thumb screws on the side of the laser harness can be adjusted to finely position the laser beam....

The red color of these wash bottles provides a visual indicator that they may contain hazardous liquids.  Constructed of low density polyethylene, these bottles include a built-in delivery tube.

The Newton’s Rings Apparatus consists of a plano-convex lens on top of a flat glass plate, held together by a plastic frame. The pressure between the lens and the plate can be adjusted by means of three thumbscrews.

These bottles provide an excellent option for storage of reagents and other materials in the laboratory. The square shape is designed to optimize shelf space. Available in three different sizes, these bottles feature polypropylene caps, are autoclavable, and provide good chemical resistance.
