Independent of electricity, lightweight and compact. LETZTEST has invented an electricity-free chemical incubator which will revolutionize water quality testing in regions with instable power supply. Use the sun or hot water for activation, then incubate your LETZTEST Tubes or Compact Dry Plates for 24 hours at 37°C.
Art. no.: 115178
This kit allows the quantification of E.coli and other coliforms for a large number of water samples in the laboratory. LETZTEST has developed this kit which is perfectly suited for analytical laboratories located in areas with limited infrastructure. The kit is still easy to transport and can be operated without electricity in the event of a power failure. It is therefore ideal for setting up a project laboratory in a remote location. Furthermore, very low running costs are possible with this kit.
Art. no.: 1094
Made of pharmaceutical quality stainless steel to collect water samples for microbiological analysis from points where the sample can not be taken directly into the sample bottle or bag ( e.g. at a storage tank).
Art. no.: 117952
Made of pharmaceutical quality stainless steel for application in drinking water analysis as-well as food, beverage and environmental water analysis according to ISO standard methods.
Art. no.: 1097
Ideally suited for different types of settings and different types of gas! The burner can be connected to a central gas supply in a laboratory or can be operated mobile in the fields by gas cartridge CV360 from Camping Gaz, or Express 444 using adapters.
Art. no.: 1098
Very compact, chemical-resistant and oil-free diaphragm vacuum pump. Thanks to the integrated manual speed control, the flow rate can be adapted to the corresponding application. The pump is equipped with a PPS pump head, a PTFE-coated diaphragm and FKM valves. It can be used for many laboratory applications.
Art. no.: 1085
Chromogenic selective agar to detect Escherichia coli and coliform bacteria from water with low accompanying flora (acc. to the draft standard DIN EN ISO 9308-1:2012) and from processed food. A water laboratory that consists of a solid QM system can pur its own Petri dishes and reduce the costs per test down to < 0,50€.
Art. no.: 114924
Instead of relying on single-use Petri dishes from abroad, we strongly recommend using our reusable glass Petri dishes
Art. no.: 1099
Reusable wide neck sampling bottle.
Art. no.: 1101
For those who need more than our electricity-free incubator, e.g. for daily use in a laboratory with the possibility of incubating samples at temperatures other than 37°C, while maintaining mobility ! These two incubators are specially designed for areas with limited infrastructure and can be used both in the laboratory and in the field.

Art. no.: 115931
Easy to use and robust. This unique multimeter measures pH, conductivity, salinity, total dissolved solids (TDS), temperature and the redox potential (different probe). Results can be transmitted to your connected device thanks to Bluetooth® technology. The portable kit works in conjunction with the application eXact iDip® for iOS and Android. Results and automatically generated reports, including photos and mapping, can be shared with responsible entities via e-mail and messenger apps.
Art. no.: 115945
Simple, Safe and Independent! A very practical and very easy to use tool for visual measurement of water turbidity which is very often convincing in practice! An essential test prior to water treatment by chlorination (Note: Chlorine is an effective disinfectant where water turbidity is below 5 NTU) and in ongoing water quality monitoring.
Art. no.: 117402
Simple, Safe and Independent! The Visual Color Comparator Test is an easy to use tool for measuring free/residual chlorine, total chlorine and pH (acidity) of water samples which is very often convincing in practice!
Why measuring chlorine and pH? In many cases testers want to know if a water was disinfected or if the residual chlorine (=free chlorine) level is still sufficient to protect the drinking water from recontamination. The Ideal level of free-residual chlorine is said to be 0,2-0,5 mg/L. Desinfection with chlorine is more effective at a pH value below 7,5.
Art. no.: 118311
Note: A small number of reagent tablets are included with the unit but larger quantities should be requested separately.
Phenol Red - for pH; package of 250 tablets:
Art. no.: 119020
DPD1 - for free/residual chlorine; package of 250 tablets:
Art. no.: 118312
