I want to ask what is the difference in terms of application between the HHH (Heinz Herenz Hamburg) Bulb Pipette Filler Standard Type (1081801) and the HHH Bulb Pipette Filler Universal Type (1081802)?

They both basically have same functions with same operations. However, universal type is longer than standard type with an adapter for pipette head (see the picture below: standard type is to your left).

 D&N Bulbs

Note: The bulbs shown are Deutsch-Neumann, but they are similar to HHH.

  • $\begingroup$ Are they used for the same pipette with the same measurement capacity or they provide different capacity of suction? Example : one is for pipette of X ml and the other can be used for pipette with higher ">X" ml. $\endgroup$ – Tomsofty33 Apr 26 '18 at 6:58
