Test tube and pipette racks provide stable, organized benchtop storage for blood draw tubes, serum microcentrifuge tubes, and pipettors during sample preparation and testing. Keeping tubes upright prevents accidental spills, cross-contamination, and clot disturbance while serum separates.

Organizing an in-house breeding lab

Racks in this collection accommodate standard tube diameters, including 10 mm to 13 mm blood draw tubes, 1.5 ml and 2.0 ml microcentrifuge tubes, and 15 ml conical vials. Multi-tier and interlocking racks allow handlers to organize sequential draws when testing multiple female dogs on the same morning.

Pipette stands and hygiene

Dedicated pipette stands hold single-channel and multi-volume pipettes vertically, preventing liquid from back-flowing into internal pistons and protecting calibrated shafts from workbench contamination. Durable polymer construction allows rapid sanitization with isopropyl alcohol between testing cycles.

In-stock tube racks and pipette stands ship same-day for orders placed before 1:30 PM CST. For assistance outfitting your lab bench, call CanineP4 at 844-673-7378 or submit an inquiry through our contact form.

Frequently Asked Questions

Why are test tube racks important for dog progesterone testing?

Test tube racks hold blood collection tubes vertically during the clotting and separation stages, preventing the clot from adhering to the tube sides or spilling. Keeping samples upright also ensures clean separation during centrifuge loading and keeps multiple female samples clearly organized.

What pipette do you need for dog progesterone testing?

Most analyzer workflows use an adjustable-volume pipette in the 20-200 microliter range for serum transfer, with matching disposable tips to prevent cross-contamination between samples. Disposable transfer pipettes are the low-cost, single-use option for rough transfers, while electronic and adjustable lab pipettes give repeatable accuracy when a test specifies exact sample volumes. CanineP4 sells pipettes with tips matched to each line.

When should you change pipette tips between samples?

Use a fresh tip for every sample. Reused tips carry traces of serum or reagent between samples and can contaminate a run, so a fresh tip each time is the single cheapest accuracy upgrade in your testing routine. Bulk tip packs keep a season of testing stocked without reordering mid-cycle. CanineP4 sells tips in bags matched to the pipette lines it carries.
