Mikroorganismen und mehr identifizieren.

Highlights

  • Frühzeitige Feststellung bakterieller Kontamination
  • Einfaches Ein-Schritt-Verfahren
  • Nachweis von coliformen Keimen und E.coli in einem Test
  • 100-ml-Proben (behördliche Meldung)

Coliforme Keime und E.coli sind gute Indikatoren für eine generelle bakterielle Kontamination und sind, aufgrund ihrer einfachen Nachweisbarkeit, ideale Indikatorbakterien für die Überwachung von Wasserläufen, Tanks und Rohrleitungen. In den WHO-Richtlinien für die Trinkwasserqualität ist ein Gehalt von null koloniebildenden Einheiten (KBE) von coliformen Keimen und E.coli pro 100-ml-Wasserprobe vorgegeben.

Mit dem Lovibond® System werden 100-ml-Proben getestet. Das Vorhandensein von nur einer KBE/100 ml wird angezeigt.

Der Test funktioniert mit einem einzeldosierten Trockenreagenz für gesamtcoliforme Keime und E.coli. Positive Proben sind durch eine sichtbare Farbänderung erkennbar. Die Durchführung des Tests für coliforme Keime ist einfach: Geben Sie ein Reagenztütchen in 100 ml Wasser, inkubieren Sie die Probe und achten Sie auf eine Farbänderung. Die Ausbildung einer gelblichen Färbung innerhalb von 24 Stunden deutet auf das Vorliegen gesamtcoliformer Keime hin.

Positive Proben werden dann durch Feststellung von Fluoreszenz unter UV-Licht auf E.coli geprüft. Ein einfaches und zuverlässiges Verfahren, das eine schnelle Aussage zur Anwesenheit oder Abwesenheit gesamtcoliformer Keime und pathogenem E.coli ermöglicht.

Der Lovibond® DI 10 Inkubator (optionales Zubehör) für Dipslides ist ideal für die korrekte Inkubation von Proben.

Take the guess work out of the flow!
Size: 58.3mm, Color: Black
I got this because when my wife makes espresso, it's watery. When i make it, it's fine. We needed a controlled Tampering method so we both do the same job. This is heavy, and being able to use the whole hand instead of fingers, not much effort is needed. Since we purchased this, we were able to make consistent espresso shots for sure.

Not as good as I expected
When it first came, the box fell apart as I was taking it out, and a lot of some kind of dirt or sand kept falling out all over my table and floor. I had the take the entire thing apart and thoroughly wash it. After drying age reassembling it, I tried it on my portafilter that came with my Breville Barista Express, but, somehow, it doesn't always make the tamping level. You would think with the ridge that rests on the side of the portafilter that it would force it to remain level, but, somehow, it doesn't, at least not consistently. It also has varying lengths (heights, or depths), and a single spring tension, so you may still over tamping or under-tamp. I was expecting it would have a censor that would just detect once it reached 30 lbs of force and cut off after that, similar to a torque screwdriver, but that's not what this is. I'll still give it 3 stars because, despite the problems mentioned above, it at least produces some amount of consistency, even if that isn't measurable; but, I can't give it 5 stars because of those issues mentioned above.

This is the one.
Size: 58.3mm, Color: Black
As an el Supremo Coffee Geek, I've wasted money on lots of different tampers. Save your money and buy this one or it's equivalent. This thing is heavy duty, solid, well-made, self-leveling, tamps at 30 pounds and is fool-proof even for fools. Also, it's a palm tamper meaning more fun and more satisfying to use as you prep the puck for your morning buzz. Buy it. You will thank me.

Super easy to use and takes the guess-work out of getting even pressure on the grounds
Size: 58.3mm, Color: Black, Size: 58.3mm, Color: Black
I have been using a hand tamper for many years and have a good idea of the pressure I am applying to the grounds in the portafilter. I honestly considered spring tampers to be a bit silly. But this tamper really does take the guess-work out of pressing the coffee grounds. The shroud helps guide the press so that pressure is applied even and flat across the surface. With the manual tamper, there will be some play when pressing, or some unevenness in pressure. This is especially true when cranking out many espressos during a breakfast party with friends. Having the spring tamper makes quick work of turning out a lot of coffees with consistency. There are no instructions for taking this tamper apart to clean inside, and you may not really need to do that very often. After each use, just pull back the shroud (the black piece that moves up and down) and wipe off the tamper (the shiny steel part). This will help prevent grounds from working their way inside. If you do want to take it apart, it’s easy. Pull back the shroud and unscrew the tamper. It will come apart into three pieces. Wipe the pieces off and reassemble. Super quick and easy. This tamper is very heavy. My scale shows 656 g (about a pound and a half). It fits the portafilter exactly, with no slop. Just place on top of grounds and press!. Don’t even worry about pressure, just push down all the way. Overall I had fun using this tamper versus my manual one. And since I make myself a cappuccino very early in the morning, I don’t have to be very awake to get a good pack on the grounds and get my coffee fast!
