this took forever to identify, but now I know what it is, EREM 2000DA is an an Excelta Roto-Pic™ vacuum tip kit, used for manual vacuum pickup of small components in electronics assembly.
  • The kit includes several interchangeable tips (PTFE, polyethylene, stainless steel) for handling delicate parts under a microscope.
  • It’s designed for manual or semi-automatic vacuum handling, not for dispensing adhesives or epoxy.
  • This package contains 5 tips, so it includes the discontinued 2080 (.004") stainless tip.
from the Excelta web site:
 The 2000DA Roto-pic™ vacuum tip kit contains one each of the 2040 (.006”ID PTFE tip), 2041 (.005” Polyethylene tip), 2043 (.012” Polyethylene), 2044 (.035” Polyethylene), 2080 Discontinued (.004” Stainless Steel)

The last photo shows the datasheet for these tips.

Note to me: second drawer, small gray cabinet

I normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box.
