LILPET LIL-50
Miniature Fixed Volume Micropipette
Compact 130 mm Form Factor · Two-Step Plunger · Designed for Diagnostic Kits
Diagnostic kit manufacturing demands miniature pipettes that can fit inside the kit box, dispense identical fixed volumes across thousands of units, and survive autoclave cycles between batches. The LIL-50 is purpose-built for that workflow — a 50 uL fixed-volume miniature pipette with two-step plunger precision and a 130 mm form factor designed for kit packaging.
Why The LIL-50?
Diagnostic kits like veterinary tests, beta-lactam testing, HbA1c, and milk testing all rely on miniature pipettes that ship inside the kit itself. Standard lab pipettes are too large; budget alternatives lack the calibration traceability that regulated diagnostic kits require.
The LIL-50 is engineered for this niche. At 130 mm in length, it fits inside Rapid Test Kit packaging while maintaining ISO 8655 accuracy through its two-step plunger and universal tip cone. Calibrated in Microlit's NABL ISO 17025 lab; available as a customizable OEM product with color-matched options for kit branding.
FITS DIAGNOSTIC KITS
At 130 mm in length, the LIL-50 is engineered to fit inside Rapid Test Kit packaging, making it the standard for veterinary kits, beta-lactam testing, tetracycline testing, HbA1c testing, milk testing, and drug abuse testing.
1% AT 50 uL
At nominal volume, the LIL-50 delivers 1% accuracy and 0.4% CV per the catalog spec, verified against DIN EN ISO 8655-2 at Microlit's NABL-accredited ISO 17025 lab.
COMPACT 130 MM DESIGN
At just 130 mm in length, the LIL-50 is the standard for diagnostic kit packaging — fits inside the kit box while maintaining ISO 8655 accuracy. Hold it like a pipette, not a syringe.
TWO-STEP PLUNGER
The two-step plunger operation enables last-drop dispensing and reverse pipetting, achieving the accuracy and CV figures prescribed by ISO 8655 standards even on viscous samples.
"Fixed 50 uL miniature pipette — 1% accuracy, 130 mm form factor." — The LIL-50 is the diagnostic kit industry's miniature workhorse — ISO 8655 accuracy in a package small enough to ship inside the test kit itself.

Ideal Applications
RAPID TEST KITS
Milk testing, drug abuse testing, GMO detection kits, and food safety panels where diagnostic kits and routine laboratory transfers.
CLINICAL & VETERINARY
Patient sample handling, veterinary diagnostics, allergen testing, and specimen processing for clinical labs.
PLATE-BASED ASSAYS
ELISA sample addition, antibody dilutions, and cell-based assay setup where consistent fixed-volume delivery drives intra-plate CV.
Other Models in the LILPET Range
The LIL-50 is one of 7 fixed-volume models in the LILPET miniature micropipette platform. All share the same 130 mm form factor, two-step plunger, and ISO 8655 calibration certificate.
