CLAIMS
We claim:

1. An apparatus for harvesting fluid from a plurality of eggs comprising:
a pump;
a pipette connected to the pump and adapted to withdraw fluid from the plurality of eggs; and
a sample reservoir connected to the pump to store the withdrawn fluid from the plurality of eggs.

2. The apparatus of claim 1, wherein the pipette is a disposable pipette.

3. The apparatus of claim 1 , wherein the pipette is a volumetric pipette.

4. The apparatus of claim 1, wherein the pipette is a disposable volumetric pipette.

5. The apparatus of claim 1, wherein the pump is a peristaltic pump.

6. The apparatus of claim 1 further comprising a first valve disposed between the pump and the pipette.

7. The apparatus of claim 6 further comprising a second valve disposed between the pump and the sample reservoir.

8. The apparatus of claim 7 further comprising a control panel operatively connected to the pump.

9. The apparatus of claim 8, wherein the control panel is also operatively connected to at least one of the first valve and the second valve.

10. The apparatus of claim 8 further comprising a pressure source operatively connected to the control panel and the pipette, wherein the pressure source can expel any contents disposed within the pipette.

11. The apparatus of claim 10, wherein the pressure source is a canister of pressurized gas.

12. The apparatus of claim 11, wherein the gas is selected from the group consisting of air, nitrogen, helium, neon, argon and carbon dioxide.

13. The apparatus of claim 10 further comprising a pressure valve operatively connected to the pressure source and the control panel, wherein the pressure valve controls the amount of pressure transferred from the pressure means to the pipette.

14. The apparatus of claim 1 further comprising a pipette gun configured to be operatively connected to the pipette and the pump.

15. The apparatus of claim 14, wherein the pipette gun comprises a retrieving button and an aspiration button.

16. The apparatus of claim 14, wherein the pipette gun comprises an aspirating cone, and wherein a tube connects the aspirating cone and the pipette.

17. The apparatus of claim 14, wherein a bracket connects the pipette to the pipette gun to improve the ergonometry of the operation of the pipette.

18. The apparatus of claim 17, wherein the bracket comprises a turn ranging from about from about 60° to about 300°.

19. The apparatus of claim 18, wherein the bracket comprises a turn of about 90°.

20. The apparatus of claim 1 further comprising a separator, wherein the separator cooperates with the pipette to minimize the inclusion of undesirable objects in the withdrawn fluid.

21. The apparatus of claim 20, wherein the separator comprises a spoon.

22. The apparatus of claim 20, wherein the separator comprises a surface curved around the separator's longitudinal axis.

23. The apparatus of claim 20, wherein the separator is perforated.

24. The apparatus of claim 20, wherein the separator comprises a screen.

25. The apparatus of claim 1, wherein the apparatus is capable of harvesting fluid from the plurality of eggs at least about 70 ml/min.

26. The apparatus of claim 25, wherein the apparatus is capable of harvesting fluid from the plurality of eggs at least about 80 ml/min.

27. The apparatus of claim 26, wherein the apparatus is capable of harvesting fluid from the plurality of eggs at least about 90 ml/min.

28. The apparatus of claim 1, wherein the pipette is transparent.

29. An apparatus for harvesting biological fluid comprising:
a pump;
a pipette connected to the pump and adapted to withdraw the biological fluid; and a collection reservoir connected to the pump to store the withdrawn biological fluid.

30. The apparatus of claim 29, wherein the biological fluid comprises allantoic fluid, amniotic fluid, vaccine, pharmaceutical fluid or laboratory fluid.

31. A method of harvesting fluid from a plurality of eggs comprising the steps of:
(i) making an opening in an egg;
(ii) inserting a pipette into the egg;
(iii) drawing the fluid into the pipette;
(iv) inspecting the fluid; and (v) transferring the fluid to a sample reservoir, wherein steps (i)-(v) can be performed in a continuous manner with multiple eggs.

32. The method of claim 31 , further comprising step (vi) rejecting the fluid.
