Building the vial holder

Step 1: Inserting the O-rings #

info

The vial holder of the v1.1 now comes in two halves; a top vial holder and a bottom vial holder. Both have grooves to insert O-rings for a more secure hold on your vials and increased protection against leaks. The thinner O-ring (#024) fits into the top piece. The thicker O-ring (#121) lines the bottom piece.

The #024 O-ring has been switched to a version with an X-shaped cross section in recently shipped upgrade kits.

  1. The O-rings are pre-lubricated with a silicone-based lubricant. If needed, remove any excess lubricant from the O-rings.
  2. The top vial holder has a groove within the body where the thinner #024 O-ring sits. Carefully insert the O-ring using your fingers, making sure to not twist the O-ring.
  3. Run your finger inside the now-occupied groove, pushing the O-ring into place to ensure a snug fit.
  4. The bottom vial holder has a groove for the thicker #121 O-ring. The O-ring will sit between the base of the holder and the heater PCB. Carefully insert the O-ring using your fingers. Make sure to not twist the O-ring.
  5. Push the O-ring into place to ensure a snug fit.

Step 2: Attach the window cover #

  1. Place the window cover over the window. It should fit snugly.
  2. Attach it using four M2.5 4mm screws (2 provided in the upgrade kit, and 2 previously used in the old v1.0).

Step 3: Place and secure the heater PCB #

  1. Remove the thermal pad from the heater PCB.
  2. Place it aside so that the sticky side is upward. Take care to not dirty the thermal pad.
  3. Insert the flex cable below the O-ring and into the groove. Pull it through.
  4. Apply pressure on the back of the heater PCB so that it lies flat on the O-ring. Maintain this pressure for the next steps.
  5. While maintaining pressure, flip the piece over and insert the two M2.5-CS 5mm screws into the holes.
  6. While maintaining pressure, take turns screwing each in until both are flush, and the heater PCB is securely attached to the bottom vial holder.
  7. Stick the thermal pad back onto the heater PCB, sticky side down.

Step 4: Complete the vial holder #

  1. Screw the top and bottom vial holder sections together so that the IR label is positioned above the flat-flex-cable.
  2. Set this aside and proceed to the next page.
