For reliable monitoring of dry and wet surfaces in the manufacturing sector, in the foodstuffs and animal feed sector, in patients- and health care, in gastronomy and trade, in training and in many other areas.

• Quick and easy sampling
• Easy and quick measurement within seconds
• Sensitive and reproducible measurement

Using the LuciPac^® Pen sampling pen, surfaces can be tested easily and quickly for contamination by bacteria, fungi and food residue. Organic contamination is indicated by the presence of ATP or AMP on these surfaces. An enzyme/substrate complex in the LuciPac^® Pen sampling tube reacts with ATP and AMP to produce bioluminescence whose intensity correlates directly with the amount of ATP/AMP present. The Lumitester PD20 or PD30 then determines the bioluminescence as a direct measure of original contamination.

The unit is easy to operate, even by non-professionals. Just moisten the swab and swipe it across the surface. Then put the swab back into the tube and push it down into the reaction chamber. Shake the tube until the reagents are released and measure the bioluminescence in the Lumitester PD20 or PD30.

20 LuciPac^® Pens each are packed in a resealable aluminium bag. Store in a dark place.

For reliable monitoring of liquids, e.g. contamination control of water and wastewater.

• Quick and easy sampling
• Exact sample volumes of 150 µl
• Easy and quick measurement within seconds
• Sensitive and reproducible measurement

Using the LuciPac^® Pen Aqua sampling pen, liquids can be tested quickly and easily for organic contamination. The organic contamination of liquids, e.g. by bacteria, is indicated by the presence of ATP or AMP in these samples. An enzyme/substrate complex in the LuciPac^® Pen Aqua sampling tube reacts with ATP and AMP to produce bioluminescence whose intensity correlates directly with the amount of ATP/AMP present. The Lumitester PD20 or PD30 then determines the bioluminescence as a direct measure of original contamination. The sampling comb ensures precise sampling of 150 µl with a deviation of ≤2 %. Test results are, therefore, highly reproducible and comparable.

The unit is easy to operate, even by non-professionals. Just immerse the sampling comb into the liquid. Then put the comb back into the tube and push it down into the reaction chamber. Shake the tube until the reagents are released and measure the bioluminescence in the Lumitester PD20 or PD30.

20 LuciPac^® Pens Aqua each are packed in a resealable aluminium bag. Store in a dark place.

Break-proof and ageing-resistant container made of rustproof, robust stainless steel or transparent polycarbonate enables the growth of the colony to be monitored without opening the container.

The anaerobic atmosphere can be generated in the vessels by evacuating using a vacuum pump and gassing (e.g. with nitrogen) or with chemical anaerobic systems.

The lid, made of UV-stable black plastic or transparent polycarbonate (PC), is equipped with a ventilation screw on the "eco" and "crystal eco" models.

The lids of the "small", "standard", "large" and "crystal" models are equipped with two corner valves including chemical-resistant hose connectors for gassing hoses and vacuum hoses (5 mm inner diameter) and provided with a pressure gauge for precisely monitoring the vacuum or overpressure (-1 to +0,2 bar).

The "standard", "eco", "crystal" and "crystal eco" vessels can be used with up to 15 Petri dishes with a diameter of 60-100 mm.

The "small" anaerobic vessel is suitable for up to 10 Petri dishes with a diameter of 60-100 mm.

The "large" vessel can hold up to 15 Petri dishes with a diameter of 60-150 mm.

Suitable insertable frames for Petri dishes, microtiter plates or test tubes are available separately.
