LILPET PRO LILP-25
Miniature Fixed Volume Micropipette with Tip Ejector
Built-in Tip Ejector · Two-Step Plunger · Designed for Diagnostic Kits
The world's first miniature pipette with a built-in tip ejector, designed specifically for diagnostic kit manufacturing where blood samples, hazardous chemicals, and infectious materials are routine. The LILP-25 delivers a fixed 25 uL dispense with two-step plunger precision and hands-free tip ejection — protecting both the operator and the sample integrity.
Why The LILP-25?
In Rapid Test Kit manufacturing, every workflow involves potentially infectious or hazardous samples. Conventional miniature pipettes force the operator to remove tips by hand — a real safety risk and a contamination vector that disqualifies the pipette from regulated diagnostic environments.
The LILP-25 solves both problems with the world's first built-in tip ejector in a miniature format. Patent filed by Microlit in 2023, the LILPET PRO line is recognized with the India Design Mark Good Design Award 2019 and the Japanese Good Design Award 2019. The two-step plunger ensures last-drop dispensing for the prescribed ISO 8655 accuracy on every cycle.
FITS DIAGNOSTIC KITS
At 130 mm in length, the LILP-25 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 25 uL
At nominal volume, the LILP-25 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.
BUILT-IN TIP EJECTOR
The world's first miniature pipette with a tip ejector. Discard used tips without hand contact — critical for blood samples, infectious materials, and hazardous chemicals.
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.
"World's first miniature pipette with a tip ejector — 1% accuracy at 25 uL." — The LILP-25 brings hands-free tip ejection to the diagnostic kit industry — safer for the operator, cleaner for the sample, faster for the production line.
