Protect your eyes over your glasses.

This mini lab notebook is a compact solution to traditional lab notebooks.

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.

Petri dishes having a raised square grid on the bottom part. The grid consists of 36 small squares; each square is identified to facilitate special type counting or location of specimens. Supplied with top and bottom in sterile shelf packages. Size: 100 x 15mm.

First test step in Identifying Pathogenic Staphylococcus.

Transparent, shatterproof, and reusable plastic dishes are useful for applications requiring resistance to most acids, bases, alcohols, esters, and aldehydes. Ridges on the top interlock with the bottom edges for stacking. Autoclavable. Size: 100 mm dia. x 15 mm deep.

Set of apparatus for carrying out 10 basic student experiments on radioactivity. In a robust Gratnell tray with foam inserts molded to the shapes of the items and a transparent lid. Includes a CD with instructions for the experiments. The experiments are designed to occupy as little space as possible on the supplied base plate, while remaining clear and easy to perform. To determine the count rates, it is recommended that a Geiger counter be used (not included).

This product is a model of a wankel engine. The transparent plastic housing enables the students to see the internal structure at all angles. The rotor starts moving when the switch is turned on. It is powered by 110V AC. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: Size: 15L x 20W x 28H cm ; Weight: 3 kg

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.

Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analog voltage display. Unit poles can be connected to protected earth, but it is not center tapped.

Shatterproof and completely safe for short-term storage of ice water, dry ice-solvent, and liquid nitrogen; also for use as hot baths. Chemical-resistant HDPE double walls are filled with CFC-free urethane foam and withstand temperatures of -196° to +100°C. Vented, insulated polyethylene cover.

With molded-in ribs for added safety when held.

This product is a small-sized model unit used for explaining the principle of a planetary gear. By setting the internal sun and pinion gears into motion (input or fixed), you can get the different outputs from acceleration, deceleration and reverse. Comes equipped with a storage case holding 10 Planetary Gear Demonstrators. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: 24L x 14W x 14H cm ; Weight: 3kg
