Pipette dispensor 25ml (red)

[Hendrix11]

I have bought one of these, was trying to get a picture up but seems fairly impossible, like you guys are hating on the brits at stuff ;P

I bought it because basically it was really cheap and came with a glass 10ml pipette tube thing. I have had a try of it and its really good and easy to use, you turn the wheel and it sucks up the liquid to where you need, what more could you want?

It also comes apart easily with removing a plastic stud. What I'm wondering is has anyone any experience with these? an with this having silicone gel at the plunger, whats the best way to sterilize if you don't have an autoclave? it says auto-clavable and I can get the silicone gel that goes with the product.

Basically has anyone had any experience with what I'm asking? With the plastic pipettes/glass rods and sterilising etc?

Cheers fellas

I was looking at pipettes to fill vials after Nalgene filtering,
but they seem expensive..

What are they for..
Sample transfer?

Recently, used one in school for lab and found it to be pretty neat, as for sterilizing it, I wouldn't know. What do you plan on using it for? I personally, like using 20ml syringes, as they already come sterilized.

Can you get them sterile?

After filtering with a Nalgene Cup Filter.. 1 liter
then transferring to 20ml vials..

60

My 60ml syringes with long tip work too..
This is for future possibly.. I use Syringe filters now..
I find it safer to just filter it straight into the vials

I remembre that the pipette tube had a small filter at the top, which is probably used to keep the liquids from being contaminated from the pipette. The bottle top filters also come with the same small filter, where the pump is connected.

That's most

That's most likely, so the sample doesn't have particles in it

Found these, which are similar to the ones I used.

Thanks for the responses guys.

I tried it out today on a batch of 100g of test e 250/mg. I sterilized the glass tube by drawing IPA into it, leaving for 30 mins, then rinsed with distilled water and baking with my vials at 176c. It only cost me £12, so I thought worth taking a shot on. I didn't sterilze the pipette pump itself as wasn't coming into any contact with the oil.

Its not bad to be fair, the main advantage over a syringe is that you only have to use one hand to draw and inject leaves the other hand to hold everything steady. Also you get a clear larger marker to draw to. you turn the wheel on the side to draw and push plunger on top, or side button to dispense. Pretty decent.
