"SCIENTIFIC HATCHERIES"

Set of 54 Includes twenty 1 g (blue), twenty 5 g (red), ten 10 g (yellow), and four 20 g (green) weights. These colored and coded stacking masses help children see mass relationships at a glance. Each color represents a different thickness and mass. Includes plastic storage box.

Lifelike anatomical landmarks such as a carotid pulse, sternum, ribcage, and sub sternal notch provide realistic CPR practice.

A thin-walled tube for efficient thermal transfer in PCR or other micro-reactions.

A high-performance, versatile large-volume centrifuge.

This kit is a unique teaching tool for introducing students to the chemistry behind plant pigments (the blueberry bio-pigment cyanidin) and how they can be used as pH indicators and fabric dyes.

Polystyrene microscope slide tray with unique step design.

Dishes for general-purpose weighing, dispensing, storage, food processing, evaporating, or drying.

For electrical circuits with low voltages and high currents; copper wire encased in highly flexible PVC; equipped at either end with a laminated plug and a fully-insulated axial jack for connecting additional patch cords.

This magnetic induction stirrer is motor-less, using advanced coil technology that produces the strongest magnetic coupling and has no moving parts making this unit 100% wear-free and maintenance free. The magnetic coil technology works on the inductive principle with alternative current (AC) as its driving force.

For filtering out fine precipitates when filter papers are unsuitable.

Economical choice for basic applications.

Ideal for classroom use, this general purpose pH paper provides a distinct color match for each pH unit from 1 to 14.

Protect your eyes over your glasses.

Sensor for triggering the digital counter in time measurements on moving objects. Suitable for opto electronic scanning of light and dark markings on moving objects or in conjunction with a reflecting foil to form a wide spaced obstruction sensor. The intensity of the laser beam is adjusted automatically according to the distance of the object. Includes reflecting foil, stand rod with screw thread, and connector lead with 8 pin miniDIN plugs.

Vibration generator for exciting oscillating and waves mechanically, such as in coil springs, a rubber cord, a wire ring or a Chladni plate. In robust plastic housing including mounting pin with 4mm socket for attaching accessories (Chladni plates, resonance wire, rubber band, etc.). Including holder for stand rod (up to 8mm dia.) on the rear side of the apparatus for the demonstration of standing waves in a coil spring. The generator is equipped with overload protection and is driven by a loudspeaker for smooth oscillations and fine travel stepping.

These graduated measuring cylinders are made of high quality polypropylene plastic and feature an easy pour spout. Extra-wide hexagon base helps to prevent spilling. Set includes 10 ml, 25 ml, 50 ml, 100 ml, 250 ml, 500 ml and 1,000 ml cylinders. Set of seven.
