The C-chip™ is an easy-to-use, precision disposable plastic haemocytometer, developed to solve the problem of conventional glass haemocytometers. Supplied individually packed, in a box of 50 slides, these Neubauer Improved type haemocytometers have 0.1 mm 0.05 mm grids, for counting blood cells (erythrocytes, leukocytes), mammalian cells etc. Supplied as box of 50 double chamber slides (100 tests). Features and benefits: • No need to coverslip • No need to wash for reuse • No more contact to hazardous materials • Accurate, reliable and repeatable • Bright grid pattern • tests per slide • Pack of 50 double chamber slides (= 100 tests) • Quartz grade optical plastic • Sturdy and strong Main applications: • Blood analysis • Cell culture; cell concentration measurement and cell viability counts • Microbiology; bacterial and fungal spores Dimensions: 25 75 1.6 mm (w l t) Chamber depth: 100 µm Chamber volume 10 µL

These Bright-Line (Rhodium coated) glass Haemacytometers are designed for accurate counting of cells in blood or other fluids, with one-piece glass construction, an H-shaped moat to form two counting areas (plateaus) and ""V"" slash at the loading side of each plateau. Each plateau features enhanced Neubauer rulings, the ruled surface being 0.1 mm below the cover glass, limiting the volume of blood or fluid over square mm to 0.1 cu.mm and over each of 400 squares (within the central square mm) to 0.00025 cu. mm. Contact of the flat, polished cover glass surfaces with cover glass supports produces an exact volume of fluid over the counting area. The difference in surface tension characteristics between the metallic surface on the chamber and the polished cover glass assures smooth capillarity for precise loading and more even cell distribution. Supplied as double chamber with two cover glasses or kit which includes double counting chamber, cover glasses and red and white pipettes, all in protective case. Spare/replacement glass cover glasses are also available, as pack of 2. • Bright Line (Rhodium coated) counting chamber • Improved Neubauer ruling pattern • Cell Depth: 0.100 mm ±2 • Volume: 0.1 µL To clean the counting chamber after use: remove the cover glass and clean with water or mild cleaning solution (e.g. 10% bleach solution). Dry the counting chamber with soft cloth/wipe, or rinse with acetone.

These round electrodes will fit the electrode holder EL110620, the electrode connector EL150426, and rubber stoppers with hole. Diameter 6-7 mm.

Designed with microprocessor-controlled dual thermocouples, this stirring hot plate offers accurate temperature control and protection from overheating. The analogue models feature a coloured LED indicator which surrounds the heat control knob illuminating the actual surface temperature in real time. Powerful magnets and motor provide stirring speeds of up to 2000 rpm and mixing capability of up to 15 L of liquid. The square plate design allows flexibility of vessel sizes and combinations. Up to four 250 mL beakers can easily fit on the surface at the same time. To keep you safe, a “hot” warning light flashes whenever the plate surface temperature is above 50°C and continues to flash until the temperature drops below 50°C, even when unplugged. The unit includes BioCote antimicrobial protection which reduces the presence of odour and stain causing microbes such as bacteria, mould, and fungi on the product surface by up to 99.99%. Formulated from silver ion additives, BioCote provides built-in antimicrobial protection to support a more hygienic laboratory environment. This model includes an integral fitting for a retort rod and allows the retort base to slide underneath. Featuring a coated aluminium top plate for rapid heating and better temperature uniformity. Please Note: BioCote® technology does not protect users or others against disease causing bacteria, germs, viruses, or other harmful organisms. This technology is not a substitute for good hygiene and/or cleaning practices.

The timer is auto-ranging for ease of use and has clear 13mm digital display and has robust metal case with durable powder coat finish. An illuminated on/off switch is mounted on the rear panel adjacent to fused appliance inlet. • Electrical Supply: 220-240 V AC 50-60 Hz • Dimensions (W x L x H): 179 x190 x 85 mm • Mass: 1.6 kg • Ranges: 0 to 9.999s; 10 to 99.99s; 100 to 999.9s; 1000 to 9999s • Accuracy: ±0.01%

For use as a light operated timing gate. Comprises a photodetector and light source each housed in a robust ABS case spaced 40 mm apart on a plastic rod. Light source housing has a battery compartment and on/off switch. Photodetector housing is fitted with pair of 4 mm sockets to allow connection to electronic timers. When the timing gate is switched on it creates a short circuit between the two output sockets, this then becomes an open circuit each time the light beam is interrupted. Consequently the timing gate can be used as a remote switching device in wide range of dynamics experiments.
