Plasma Cleaning Process

Pipette tips are lowered into the electron streamers and plasma. Plasma is then aspirated then dispensed 6 to 8 cycles. Plasma intensity increases with each cycle.

The PureTIP LHC cleaning process reduces random surface effects that degrade liquid handling precision and accuracy, even with new disposable tips. This product improves the reproducibility of results and maintains it through all reuses. Cleaning times are consistent with tip changes, but with no time lost for labware replacement, overall productivity increases. PureTIP LHC reduces plastic tip waste and the waste from product packaging.

Typical Use

Typical operation is for the liquid handler to lower a rack of pipette tips into the PureTIP LHC cleaning station for approximately 30 seconds of direct plasma exposure. The cleaning station turns on when the tips break a light beam and goes off when the tips are raised. While the plastic tips are in the cleaning station, the liquid handler is programmed to run a standard mix, pulling plasma into the pipette tip and then expelling the waste gas. Typically, 6 or 7 cycles are programmed in the mix step. After treatment, tips are ready for immediate re-use.

Benefits

• PureTIP LHC cleans better than any other washing technology – in most applications, the PureTIP LHC will clean to background, so there is no difference between plasma cleaning and a new tip.
• PureTIP LHC can save up to 98% on the cost of disposable tips and extends the life of fixed tips.
• Incorporating the TipCharger System can result in a time savings of 10-30 seconds for every microplate processed or rack of tips cleaned.
• Clear away the clutter and save time: Integrating the PureTIP LHC eliminates the need to store cases of new pipette tips and dispose of racks of hazardous used tips.
• Compatible with most liquid handling platforms, including systems from Beckman, Hamilton, Tecan, Agilent, and Thermo.
• Compared to single-use, using PureTIP LHC to clean and reuse a single rack of pipette tips just 1x greatly reduces a lab’s total Greenhouse Gas (GHG) Emissions based on a CO2 equivalency comparison.
• Cleans 20uL – 300uL tips.
• Cleaning pipette tips with plasma creates no liquid or solid waste.
• Tip costs go down 90% if re-used 9 times.
• Easy to install, minimal maintenance. Consistent, reliable performance for years. Plasma effectiveness does not diminish over time.
• Available in the 96 and 384 format to clean pipette tips and the 384 and 1536 format to clean pin tools.
• Proven in Pharma and Biotech labs to completely remove DNA, RNA, siRNA, mRNA, or any other genomic material small molecules in DMSO Proteins, enzymes and any other biomolecule.*
