Dispensing arachnid toxins: probably the Sydney funnel web spider in
both toxicity of the venom and the quantity. The smaller male dispenses
about half the quantity of the female, but the venom is five times more
powerful, amongst the most powerful venoms in nature. It is a beastie
that is found only within a 160 km radius of Sydney and can cause
regular human death if the bite is not treated medically within an hour.
Some snakes are worse but only because the quantity of venom is greater.
After all, the SFW spider (female) grows only up to 7 cm long (male 4
cm). The venom is best not put in your syringes :-)

And they say that they can avoid the disaster causing centric rings that are oftenly caused by the today's way of manufacturing. The DL guys are from Camalot, but started on their own, of some reason.

The question is if they can manage 80 and 160 microns dot dispensing. You can see the new pump and syringe yourself at <www.asymtek.com> or read in EMI october -99 Volume 10 No 8 page 8.

I had a dicussion about the world's most venomous spider, and I said it's an australian creep making it's net like a trumpet, lives unseemingly near people in gardens and is named 'minors' or something like. Wrong said my opponent, the most deadly is a southafrican 'sand crab spider'. Aussilek, check under your bed and tell me, I think I am right.
