Hi all,

I am just curious to know, if there is any gender/ experience bias in the way we use tips for our pipettes.
Please answer the questions.

Thanks,
Ameya

Eum, as long as people dont fill in their gender... its not really usefull since you cant know who (male-female) answered the two other questions....

[gebirgsziege]

oh, I answered from top to bottom and then left to right - this is very important and I am really neurotic about it - everybody in my lab keeps their fingers from my tip boxes

So for me its two answers  instead of one

Lol, why is that so important?

Altough: I can understand why others need to stay off your boxes... I am a bit the same, but for other reasons: contamination....

I also answered 2, didn't even consider just one.

I too do Left to Right, but is Bottom to Top      and yes, it HAS TO BE that way  

[gebirgsziege]

A long time ago I started to sort EVERYTHING that way when doing DNA Extraction - so the reaction tubes -  top to bottom left to right, I think mainly because we are using 8 piece PCR stripes. This reduces the risk of mixing samples and getting confused a lot when doing large extractions (i.e. 150 - 200 samples a day) -  you have a automatic order to follow AND can control with the tips used where you are. At some point it got obsessive it seems....

Probably should consult a psychologist because of this!  

But no way to do it in another way, I would have the feeling to have made a mistake or mixed things up.....

[Chakchel]

There is one thing missing in this poll.
Is the person left or right handed?
I guess this has more influence than the gender of the person.

[casandra]

I'm glad I'm not as neurotic as some of you people (esp you, gebZ)...I just keep my tip boxes under lock and key.....and booby-trapped...

or perhaps, we also choose the order according to how we read or write...the cultural connection? the western people would favour left to right then top to bottom...the arabs (and jewish?) right to left and the chineses and japanese- top to bottom....or something like this....what about in Hindi, Ameya?

[gebirgsziege]

and the thing is you are getting even more neurotic with age

But as I see from my students it is not depending on the culture or on whether you are left or right handed - some people even "draw" when taking out tips - I once had a student who took the first tips from a box "drawing" houses, flowers, suns, smilies....

oooh...this is getting more interesting...perhaps a right vs left brain functioning?

I can see this.. It makes sense...

Its because you want to maintain a certain order , a certain workmethod.

However: I understand it when you start with a fresh box (fille completely), but what when you start with a box that is half filled? They you cant really use the counting of the tips as a control? Or you do you remember where you started at? (by for example always starting at a new row.. and thus for example leaving a few tips in the box of a non complete row? .. if you get what I mean?)

Haha, Pito, that's exactly what I do, start in a new row/column    I'm with gebirgsziege there, I'm used to follow a certain order as this makes it easier to spot mistakes (or rather not make them).

I also have a labmate that "draws" in her tip boxes, I find it very odd but fun, thought it will really stress me to use her box     maybe I need help

This is interesting, I'm with you,   almost a doctor  
I too do Left to Right, and is from bottom to Top.

and when I fill in the tips, is from left to right, but from Top to bottom...usually.
I used to draw on my tips box too... kinda coincident. show u all my art next time.

Are you talking about the same thing?

Draw on your box or make drawing in your box with the tips?


I can see how the logic arises when working with tips.. but for me: I only use a systematic why like that when I need to count and thus need to know where I am (wich well or ..) But if that is not the case, then I use them random.

[Ameya P]

So far, atleast 16 members on the forum were jobless or wondering about their psychological state (while I slept peacefully).

Pito, I had thought that as a creator of the poll, I would be able to see all votes individually somehow and that would help me understand, if there is a gender bias.

For the same reason again, I would have also liked to know, if experience makes you neurotic. So far, only gebirgsziege  has voted for that.

Draw with tips, that's something I have not seen/ heard of. Probably somebody should post some pics in Casandra's art gallery

Reg. your cultural logic, Casandra, I go right to left, bottom to top and there goes your theory to pieces.

And above all and to everyone'e envy, I DONT FILL MY TIP BOXES!!!!! There are people in the lab who do it for me. Yes,  I am spoilt  geek
