Robustly made from injection moulded Acrylic, this is a modification of the ‘classic’ design. With four compartments for holding desiccating and humidifying components (e.g. silica gel or anhydrous calcium chloride and water or cotton wool soaked in water) a piece of fine mesh is placed over the compartments and the lid placed on top to hold the mesh in place. This mesh layer ensures the organisms cannot come into contact with the desiccant etc. below. The clear lid of the chamber has slightly raised ridges which divide it into quarters, to facilitate the placement of tracing paper or card segments, creating different levels of opacity or for light to be blocked out completely. This allows a range of condition gradients within the chamber to be created. The edges of the lid can also be blacked out if required, to augment the dark conditions. The organisms being tested (e.g. woodlice or maggots) are then introduced via the single 18 mm diameter hole in the lid. The lid fits onto the base in such a way that the top segment guides align with the compartment walls below, which means the different light level sectors of the lid will match the compartments in the base precisely.

Burettes ● Chemistry Kits ● Chromatography CHEMISTRY Pipette Rinsing System A B Pipette & Burette Rinsing System E D This useful washing/rinsing system allows pipettes and burettes to be automatically rinsed when connected to a tap and drain outlet. Particularly useful where unpleasant or hazardous liquids have been used, the apparatus holds pipettes and burettes up to 600mm in length. For convenience and flexibility, the washing/rinsing system is available as separate components. 1. The polyethylene rinser/washer fills via the spray nozzle on the top rim. Contaminated water will syphon out totally, once the syphon point at the top of the rinser has been reached via the large diameter drain situated at the lowest point, before refilling automatically. 2. During washing the pipettes/burettes are housed in a specially designed basket, which minimise breakages as it buffers the glassware tips against the soft polyethylene base. 3. A soaking jar is available, which will hold a pipette/burette basket, to allow the glassware to soak before rinsing. Low water flow rate is NOT a problem, but it is better to adjust the flow for a cycle of about 90 seconds.
