Mystaire® PCR Prep Stations
Compact laminar flow enclosures that reduce the risk of sample contamination while performing polymerase chain reaction experiments.
Airborne contaminants are prevented from entering into the work zone through constant positive pressure HEPA filtered air. Each PCR prep station is equipped with a built-in 254 nanometer shortwave lamp to effectively decontaminate the work area between amplifications. Safety interlocks are included on all PCR prep stations to prevent operator exposure to potentially harmful UV radiation.
MY-PCR prep stations are bench-top personal clean zones allowing the operator to amplify RNA and DNA while minimizing the potential for background from airborne contaminants.
*Note: MY-PCR and FE-PCR are not biological safety cabinets. They are designed to provide process protection only from potential airborne contaminants found in the laboratory space.
- Class 100 vertical laminar flow air
- 15-Minute UV light timer
- Clear polycarbonate construction with chemically impervious polypropylene work surface
- UV shelf with integrated pipette holder
- Electrical cord pass-through port
- Sash position switch and overlap to prevent UV light exposure

PR1MA™ Sealing Mats
PR1MA™ 96-Well PCR Sealing Mats are high-quality, reusable silicone mats designed to provide a secure, evaporation-resistant seal for 96-well PCR plates. Measuring 4.67 In. (L) x 2.90 In. (W), These mats fit standard 96-well formats and help maintain sample integrity during PCR and other laboratory workflows.
The pierceable silicone construction allows for easy sample access with pipette tips or needles without compromising the seal, reducing the risk of contamination or sample loss. PR1MA™ sealing mats are engineered to minimize evaporation, helping ensure consistent and reliable experimental results. Suitable for use across medical, pharmaceutical, food industry, and molecular biology applications, these sealing mats are rigorously tested and certified free of detectable RNase, DNase, DNA, and PCR inhibitors, making them ideal for sensitive molecular assays.
Main Attributes
- Pierceable silicone sealing mat for convenient sample access
- Evaporation-resistant seal to minimize sample loss
- Compatible with standard 96-well PCR plates
- Dimensions (L x W): 4.67 x 2.90 In.
- Suitable for medical, pharmaceutical, food, and molecular biology use

PR1MA™ Taq
- Ideal for routine PCR applications as well as genotyping, colony PCR, and fast PCR
- Improved template affinity and solubility for higher enzyme activity and greater yields
- Proprietary buffer optimized for a variety of assay conditions
- Conveniently supplied as a 2X Master Mix or in a 2-tube format of polymerase and separate 5X buffer
PR1MA™ Taq provides superior results for routine applications. Modified to improve DNA-binding, this polymerase offers higher solubility and greater template affinity, resulting in consistently superior performance. PR1MA™ Taq Polymerase exhibits a 5' to 3' nuclease activity, but no 3' to 5' (proofreading) activity and works well with a wide range of DNA templates including GC-rich sequences.
The polymerase is supplied with a 5X buffer containing MgCl2 and a proprietary mix of enhancers (dNTP's not included). For convenience, PR1MA Taq is also available in a ready-to-use 2X Master Mix - just add primers and template DNA. Our "Red Dye" Master Mix incorporates a red-loading dye that allows amplified samples to be loaded directly on an agarose gel. The red color aids in visualization during pipetting, and higher density of the buffer ensures that the samples will drop into the gel wells.

Labcon Zap™ Slik Aerosol Filter Pipette Tips - Refill Lid
ZAP™Slik Aerosol filter Pipette Tips from Labcon combine the higher standard of ZAP™ filters with our own unique low retention pipette tips. These aerosol tips provide you with complete protection from sample carry-over at the same time they reduce sample retention. Incorporating a robotically inserted 10 uM filter with a sponge-like porous pathway, ZAP™Slik tips have such a small pore they even block fluids in the unlikely event that you should over-pipette. And our SuperSlik® polypropylene increases the hydrophobicity of tips surfaces, so they have up to 10 times less fluid retention.
ZAP™Slik Aerosol Filter Pipette Tips have been proven in independent studies to block aerosol contamination. But unlike some leading brands of self-sealing aerosol resistant pipette tips they have no cellulose gum, toluene solvent, or colored dyes in the filter to mix with and contaminate your sample. Also, unlike self-sealing aerosol tips, ZAP™ tips can be autoclaved in a steam autoclave, and ZAP™ tips will not wick fluids like cellulose filled aerosol resistant tips. You don't have to worry about how you hold your pipettor. Our ZAP™ tips in sterile racks, like all our other sterile products, receive valid sterilization processing compliant with ISO 11137. So unlike "pre-sterile" tips from other pipette tip suppliers you can use ZAP™Slik tips for diagnostic and regulated procedures. And ZAP™Slik tips are RoHS compliant, unlike other low retention tips, so you don't have to worry that additives will migrate into your sample.

Labcon ZAP™ Slik Aerosol Filter Pipette Tips - Hinged Lid
Each style of ZAP™ SLIK Tips is designed from the beginning to fit precisely the range of pipettors listed in the fit charts. We carefully inspect the fitting with the actual pipettors, not just with measuring gauges. This means you won’t have to worry about leaking Tips and you don’t have to use extra force to mount these Tips.
ZAP™ SLIK tips feature a pure 10 uM pore size patented filter without any dyes or additives. The pores on this filter are 100% smaller than those in other aerosol tip brands. A smaller pore guarantees that your pipettor barrel will be kept clean of DNA, radionucleotides, and other contaminants. And this filter works to block fluids without any contaminants in the filter so you never have to worry that your work will be spoiled if your sample contacts the filter.
Real World Lab Tested
Labcon® ZAP™ Slik Tips are developed using their own in-house laboratory and tested on real pipettors. they don't use "pin" gauges or other unrealistic testing methods.
Quality Certification
Certificates are on file by lot number for all test results and available from the certificates page.
Virgin Resin
Only 100% Medical Grade virgin polypropylene resins are used in ZAP™ Slik Tips. No recycled plastics or commodity-grade resins.
FDA Registered Manufacturing
Labcon® is the only major pipet tip supplier to be registered by the U.S. Food and Drug Administration (FDA)
Sustainable Product Design
Like all Labcon® products, Eclipse tips are designed from the beginning with sustainability in mind. These products go far beyond simple recycling to offer real Earth Friendly® solutions.

PR1MA™ SmartGlow™ DNA Safe Stain
- Replaces hazardous Ethidium Bromide (EtBr)
- Better sensitivity than EtBr
- Detect as little as 0.1ng of DNA
- Two types available
- PS Pre Stain
- LD Loading Dye
- Excitation by UV light or blue light
- Compatible with Accuris SmartBlue™ Transilluminator
- Ships at ambient temperature (stored at 4°C)
PR1MA™ SmartStain™ PS (Pre-Stain) can be used as a direct replacement for Ethidium Bromide in agarose and polyacrylamide gel electrophoresis. The stain emits green fluorescence when bound to dsDNA or ssDNA and emits red fluorescence when bound to RNA. PR1MA™ SmartStain™ PS exhibits excitation peaks at 290 nm and 490 nm, allowing it to be used with UV and blue light.
Protocol:
- Prepare 100 mL of agarose or polyacrylamide solution.
- Add 5 uL of PR1MA™ SmartStain™ to the gel solution before pouring gels.
- For enhanced results, add PR1MA™ SmartStain™ PS to the running buffer at a ratio of 5 uL per 100 mL. Adding PR1MA™ SmartStain™ PS to the running buffer will result in increased sensitivity and better detection of small quantities of nucleic acid.
- After electrophoresis is complete, view the gel using a UV or blue light illuminator
