PR1MA™ Starter Kit
The PR1MA™ Starter Kit is a comprehensive package that includes everything required to get started with accurate and reproducible pipetting. With this kit, you can ensure that your liquid handling tasks are consistent and precise. The PR1MA Starter Kit is perfect for new labs and customers who want to upgrade their existing pipetting equipment.
The PR1MA Starter Kit is different from other liquid handling starter kits because it contains four pipettes that cover a wide volume range of 0.5 µl to 1,000 µl. These pipettors are designed to provide accurate and reproducible results, and they are perfect for a wide range of applications. The pipettor volumes include 0.5 to 10 µl, 2.0 to 20 µl, 20 to 200 µl, and 100 to 1,000 µl.
In addition to the pipettes, the PR1MA Starter Kit includes three racks of PR1MA Low-Retention Pipette Tips. These tips are specially designed to reduce sample retention and ensure accurate and precise pipetting. The kit also includes a six-position carousel stand that can hold all four pipettes and a PR1MA Backpack for easy transport.
This kit offers over $250.00 in savings compared to purchasing the kit components separately!

PR1MA™ Extra Stretch Sealing Film
Flexible, airtight laboratory seal.
PR1MA™ Extra Stretch Sealing Film is a colorless paraffin/polyolefin film that molds to almost any surface, creating a secure seal for a wide range of laboratory containers. It adheres to test tubes, centrifuge tubes, petri dishes, flasks, bottles, and beakers, making it an essential tool for protecting sensitive samples.
This latex-free sealing film provides a strong yet flexible moisture barrier while allowing controlled exchange of H2O vapor, O2, and CO2, ensuring sample integrity without compromising off-gassing. Its unique formulation makes it stretchable, moldable, and self-sealing, sticking to itself or nearly any material. Ideal for use at low temperatures (including LN2 applications) and at higher temperatures, it forms an extraordinarily liquid-tight, airtight seal for dishes, tubes, glassware, and plasticware.
Whether you're preserving sensitive biological samples or securing vessels for transport or storage, PR1MA™ Stretch is the go-to sealing solution trusted by scientists across research, pharmaceutical, academic, and industrial laboratories.

PR1MA™ TC9639 Gradient Thermal Cycler
The PR1MA™ TC9639 Thermal Cycler provides consistent, reliable results for laboratories with medium to high throughput. From its large, touch-screen user interface to its unique, multi-format block, this cycler is loaded with features. The program wizard and 10 pre-installed programs make it easier than ever to get up and running.
The fully adjustable heated lid prevents condensation and evaporation of samples. Lid temperature can be programmed, and when the block temperature is below 35°C, the lid automatically shuts off. The heating and cooling of the block are precisely and accurately controlled within exceptionally tight tolerances by a proprietary algorithm that simulates sample temperature.
With the multi-format block, there is no need for the expense of multiple interchangeable blocks. The PR1MA™ TC9639 has the flexibility to accept 96 × 0.2 mL tubes, a 96-well plate, 0.2 mL strips or 39 x 0.5 mL tubes all in the same sample block. For protocol optimization, a gradient can be set up across the block. An optional in-situ adapter allows for the incubation of slides. Additionally, the unit may be purchased with a 384-well sample block.
Compatible with PR1MA™ and Accuris™ PCR reagents. For research use only.
A large, full-color touchscreen serves as the operations center where all functions are accessed. From the “Home” screen, simply touch an icon to view the last run program, enter the program library, or use the program wizard to quickly enter a protocol. In addition, icons for favorite programs can be added for faster access.
The program wizard guides users through quickly setting up a protocol on a single screen. Once entered, programs are shown graphically and can be edited by simply touching the step that requires modification. Time and temperature increments can be built into programs as well as slower ramp rates. Storage capabilities are unlimited; programs can be stored in public folders, private (password-protected) folders, or on a flash drive. The full virtual keyboard allows for alphanumeric naming of programs and folders.
Main Attributes
- Gradient capabilities- ideal for protocol optimization
- Intuitive touchscreen control- Works even when wearing gloves!

PR1MA™ Long-Neck Pipet Controller
The PR1MA™ Long-Neck Pipet Controller is an advanced controller designed specifically for enhanced comfort and ergonomic pipetting, especially when working under hoods or in biosafety cabinets. Its extended neck design allows users to rest their elbow on the benchtop or work surface while pipetting—significantly reducing strain on the shoulders, elbows, and wrists.
This ergonomically engineered pipette controller helps prevent repetitive strain injuries by eliminating the awkward angles commonly required during extended pipetting sessions under the hood.
The PR1MA™ Long-Neck Pipet Controller also features a retractable kickstand, which folds out to support the pipette at an optimal angle when not in use and automatically returns to a neutral position to avoid interference during operation.
With a pressure-sensitive speed control, 8-hour rechargeable lithium battery, and compatibility with 1 mL to 100 mL serological pipettes, the PR1MA™ Long-Neck Pipet Controller is the ideal solution for lab professionals seeking comfort without sacrificing performance.
Main Attributes
- Long-neck design ideal for use under hoods and biosafety cabinets
- Promotes ergonomic posture – rest your elbow on the bench
- Reduces risk of repetitive strain injuries
- Retractable kickstand supports pipette when not in use
- Cordless and rechargeable – up to 8 hours of continuous use
- Pressure-sensitive speed control for precise aspirating and dispensing
- Compatible with 1 mL to 100 mL serological pipettes
- Lightweight and balanced for comfortable extended use
Experience enhanced comfort and productivity with the PR1MA™ Long-Neck Pipet Controller.
PR1MA™ Touch Power Supply
- Touch screen control
- Bright color display
- Dual orientation, auto-rotating display
The PR1MA™ Touch is a workhorse electrophoresis power supply, ideal for the efficient separation of nucleic acids and proteins as well as basic western blotting applications. Four pairs of output jacks are wired in parallel for connecting multiple electrophoresis tanks. A color touch screen allows quick setting and monitoring of all run conditions, including run time, voltage, and current. Users can select “Constant Current” or “Constant Voltage” during an electrophoresis run, keeping the chosen parameter fixed as resistance changes. The dual orientation design with a rotating display allows the PR1MA™ Touch to be installed in the most convenient location, on a shelf or bench, saving valuable space.
The PR1MA™ Touch features a logical user interface.
Setting up an electrophoresis run couldn’t be easier; simply touch the parameter to select it, press the “up” and “down” arrows to adjust the value, and then touch “Start”. All parameters are always displayed, with no need to toggle between Time, Voltage, or Amperage. In addition, the run status is always displayed.
