Vacuum pump, 2-stage
Vacuum pump, 2-stageVacuum pump with a wide range of laboratory and industry applications. Sturdy, long-life construction. 2-stage rotary vane vacuum pump with oil injection and lubrication system. Topping-up oil included, but it is recommended to order extra 069530 Vacuum oil.
Van de Graaff generator
Van de Graaff generatorGenerates very high DC voltages, but is safe to use due to low output current.
The generator features a conducting sphere with a diameter of 220 mm.
The sphere is fitted with a Ø 4 mm socket for connecting other equipment via a lead.
Viewing chamber
Viewing chamberThe demonstration cuvette is made of clear plexiglass and measures approx. 9 x 11 x 3 cm. It has a rounded bottom so that there are no corners where small animals can hide, making observations easier. The transparent construction makes it possible to view the contents from multiple angles, and the cuvette is suitable for both studying and photographing collected organisms.
Voltaic pile
Voltaic pileThe voltaic pile was the first galvanic battery. Invented by Alessandro Volta in 1800, it facilitated research into electrical currents. This model closely resembles the original design, but using more modern materials. Plexiglas replaces the original wooden parts.
