Gentle pump solves many problems.
A Verderflex pump with a gentle pumping action has solved a sludge removal problem for a TV manufacturer. It also manages to empty two other waste slurry tanks in its spare time.
When researching certain germs and bacteria in pig's manure, the prepared carriers of the bacteria are infected by the samples.
The samples are cultivated on a foodstuff, which is injected into the carrier (usually Agar) and allowed to multiply.
The samples are then studied under the microscope and the results of the cultivation further analysed.
The Verderlab peristaltic dosing pump is used in such applications, first to dose the Agar into Petri dishes and then to dose the prepared sample onto the Agar.
The Verderlab CD 70 has been chosen for such procedures because it meets GMP regulations, and with its smooth stainless steel housing it provides a complete, reliable dosing system.
Agar is a difficult product to dose because it is very viscous and its temperature can reach up to 80§C.
In this application the amount of agar to be dosed needs to be very accurate.
In between several dosings, intervals must be pre-programmed to enable the dishes to be changed and also to allow changes to the total number of dishes that need to be filled.
All media pumped must be clean, reproducible and documented.
