School, vocational and university teaching labs. Durable basics bought in class sets, usually against a term budget or a tender, and often as a whole room at once rather than item by item.
Made of good-quality plastic with a quality spring, giving accurate readings and a clear scale in both newtons and grams. Resolution 0.2 N and 10 g, measuring up to a maximum of 10 N or 1,000 g. Used to measure the force and weight of objects and as an accessory in science experiments or general work.
Clear plastic container with a scale reading rainfall up to 35 mm; Mouth diameter 8 cm, about 27 cm from base to mouth; Cylindrical rain gauge 34 mm in diameter and 80 mm high
Microscope with magnification up to 400x, for viewing small specimens that cannot be seen with the naked eye and that must be prepared on a slide or viewed from a permanent slide, starting with simple specimens such as algal cells, stomatal cells and onion root cells.
Dual dimmable LED illumination: transmitted (bottom) light for slides, incident (top) light for opaque specimens; Head: monocular, inclined 30°, rotatable 360°; Eyepieces: wide-field WF10x/16 mm with pointer, and WF25x/8 mm
A basic science-laboratory instrument for heating and burning chemicals to observe the flame colour when studying the properties and composition of elements, or for use with a tripod and wire gauze to boil water, chemicals and mixtures; also for flame-sterilising equipment in science laboratories, tissue-culture rooms and other work that requires heat.
Made of high-grade stainless steel, rust free; Light in weight yet sharp; Hold firmly, do not blunt easily and pin smoothly; A wide choice of standard sizes; 100 needles per box
Used for flame-sterilising equipment in laboratories and tissue-culture rooms, for boiling water, chemicals and mixtures, for burning substances in flame tests to study elemental composition, and for other heat work such as welding, joining and flaming
Wooden-clamp test tube holder, suitable for test tubes 1.5 - 3 cm in diameter. Used to hold hot test tubes, glass rods and thermometers for the operator's safety. One end of the holder has a metal rod for mounting on a boss head or connector and stand to set up apparatus for scientific experiments, or for use when boiling solutions.
A triangle, or wire triangle, supports a crucible while it is heated over a Bunsen burner or other heating device so that the crucible is in direct contact with the heat. (Choose a triangle whose opening fits the base of the crucible.)
5x magnifier, metal frame, dia. 75 mm; Glass convex lens providing the magnification; Magnifier 3 inches in diameter; Lens set in a plastic frame with a handle
Made of aluminium, folded into a U shape and perforated for inserting the metal rod; the set includes a U-shaped metal insert; Used to support equipment such as beakers and other laboratory apparatus
Wire gauze 10 x 10 cm, a basic item in science classrooms and laboratories. It supports apparatus or vessels such as beakers and crucibles for boiling or heating over the flame of an alcohol burner or Bunsen burner; placed on a wind shield or a tripod, it helps distribute the heat evenly across the vessel.
Wire gauze with asbestos, a basic item in science classrooms and laboratories for use with a wind shield, tripod, alcohol burner and Bunsen burner. Vessels are placed on it for heating over the flame of an alcohol burner or Bunsen burner; the heat-resistant asbestos pad keeps the vessel out of direct contact with the flame and helps distribute the heat evenly and consistently.
