Does pipetting with sterile tips and a nonsterile pipettor make sense?
The photo above depicts a daily routine for many scientists. They insist on sterile pipet tips. They gown and glove and mask to avoid contamination and then put a sterile tip on a pipettor with a barrel that is non-sterile and aspirate out of a flask that is then potentially contaminated. Does this process make sense? Does a more hygienic procedure exist?
The nUVAClean UV Pipette Carousel is the solution. MTC Bio’s nUVaClean™ is the first and only pipette rack that not only organizes and protects six pipettes, but also destroys more than 99% of contamination. The patented nUVaClean™ carousel uses a germicidal UV-C lamp with a high-efficiency reflector/concentrator that completely bathes pipette shafts in 254nm UV light. This exposure destroys unwanted microbiological contaminants and prevents cross-contamination in PCR and other sensitive procedures.
Just place single-channel pipettes of any range or brand in the nUVaClean™ and press the “start” button to begin the auto-decon cycle. After 28 minutes, the nUVaClean will power down automatically, delivering up to 6 pipettes that are safe, clean and ready for use. Brochure and ordering information can be found here.
Could Parafilm be Facing Extinction?
Parafilm was invented in the United States in the mid-1930s (often cited as 1934-1936) by the Marathon Paper Mills company. Originally trademarked in 1934 and marketed in 1936 as a moisture-proof, self-sealing wrapper for applications like map mounting, it quickly became a staple in laboratories for sealing, covering, or wrapping items. For a complete history lesson, click here.
This product has been referred to as Cling Wrap on steroids. The duct tape of science. The Forbidden Cheese. But it could soon face extinction after its 90+ year run.
HyperStretch™ is a colorless plastic / paraffin film that molds to almost any surface. It seals and adheres to an endless list of lab vessels and containers including test tubes, centrifuge tubes, petri dishes, flasks, bottles and beakers. HyperStretch™ Sealing Film is an invaluable laboratory tool.
A proprietary formula of paraffin / polyolefins, HyperStretch™ Sealing Film is latex-free and provides a strong but flexible moisture barrier that protects sensitive samples while allowing exchange of H2O vapor, O2 and CO2. This seal allows off-gassing without sacrificing integrity.
HyperStretch™ is moldable, stretchable and sticks to itself or almost any material. It can be used at low temperatures including LN2 applications, at higher temperatures on dishes, tubes, glassware, and plasticware, and as an overwrap for lids, caps and stoppers to form an extraordinarily liquid-tight, airtight seal.
HyperStretch Steri-Sheets™
Sterile Seals for Sterile Samples
The stretchiest paraffin sealing film on the market is back with a suite of new sizes and sterile packaging configurations. When so much work in the lab calls for sterile sample containers, shouldn’t your sealing film be sterile too?
HyperStretch™ Steri-Sheets™ are pre-cut in 2×4 and 4×4 inch sheets, offering ideal sizes for petri dishes, flasks, plates, and a variety of other containers. Steri-Sheets™ are packaged sterile in resealable bags of 100 ready-to-use sheets.
Saving You $$ on Chemicals
Chemicals and solutions are used in every lab. But if you shop for chemicals, such as acetonitrile, HPLC in 4X4L case you will find prices such as $3,580 per case (Fisher A998SK-4) from Fisher Chemical. But at Millipore Sigma, the price for the same chemical is $2,160 (439134). We offer the exact same quality product from Spectrum Chemical (HP412-4LT-CS).for $366.25. That is nearly 1/10th the web price advertised on Fisher’s website. (Prices quoted are active as of 1/9/2026.)

Managing your Overall Lab Spend
We manage portfolios of items for each of our clients. At the beginning of each year, we conduct a complete review of each client's portfolio. We examine each item and ask the following questions:
- Is the item being routinely purchased?
- Are there better, less costly alternatives that are now available?
We then communicate this information to our clients to obtain their feedback on recommendations.
This is the type of personalized service that our clients have come to expect. This is why we assign custom part numbers to all our clients' items.
If your current supplier isn’t helping you achieve your cost saving goals, give LPS a try! We love to serve. Schedule an appointment today.
