High quality reagent strips for urinalysis, supplied in a pack of 50. Uristix test for Glucose (g) and Protein (p).

Bacti-Caps provide firm, positive culture tube closure whilst allowing controlled gas interchange. They are an excellent and more practical alternative to wool or foam plugs. Suitable for most standard rimless test tube sizes. Made from chemically resistant plastic, colour coded and autoclavable.

Nichrome, designed to be held in needle holder. (DI05920).

Flexible loops for easier collection and inoculation Volume: 10 µl Length: 200 mm Sterilised by irradiation

Non-Sterile, disposable. NOT individually wrapped. Polystyrene, free from heavy metal.

For the measurement and collection of gas evolved by aquatic plants during photosynthesis. The gas evolved can be measured by the calibrated capillary tube and drawn off for analysis by the plastic syringes. Mounted on plastic panel 190 x 150 mm.

For demonstration of heliotropism and geotropism. Germinating seedlings are pinned to the cork table which is rotated by an electric motor at 4 revolutions per hour. The motor is spindle mounted and may be clamped so that the place of the table can be set at any angle between horizontal and vertical. An acrylic cover is provided for the cork table to shield the seedlings from draughts. The cork disc has 10 cm diameter.

For investigating the uptake of water and transpiration of cut shoot. The apparatus can be submerged in basin of water while the cut stem is mounted. The graduated capillary tube is 100 mm long with a 1 mm bore. Mounted on stand. Dimensions (H x W x D): 140 x 85 x 65 mm.

Consisting of a graduated narrow bore glass tube fitted with a vessel to take a plant shoot at one end and a funnel with glass stopcock mounted vertically. Complete with wooden stand.
