| Description | Thermoconductive Tube Racks are precision-engineered sample modules manufactured from a novel thermo-conductive alloy material, designed to evenly distribute temperature across all wells providing uniform and consistent temperature to all samples (+/-0.1°C)The modules eliminate variability which Thermoconductive Tube Racks are precision-engineered sample modules manufactured from a novel thermo-conductive alloy material, designed to evenly distribute temperature across all wells providing uniform and consistent temperature to all samples (+/-0.1°C)The modules eliminate variability which originate from tubes placed directly into ice, dry ice, alcohol baths, water baths and other temperature sources. - Ideal for cooling, snap freezing, heating or thawing
- Helps keep samples organized and dry
- All tubes upright and indexed
- Reproducible method
- Removes all problems created by placing sample directly in ice: variable sample temperature, wet labels, contamination risk
On ice - Adapts from ambient (25°C) to <4°c in="" 60-90="">
- Samples and labels stay dry
- Hours of ice cooling without direct ice contact
On dry ice - Adapts from ambient (25°C) to -78°C in approximately 5-7 minutes*
- Eliminates ethanol from snap freezing
- Equal or better freezing rate as compared to direct immersion into dry ice or alcohol slurry
In liquid nitrogen - Adapts from ambient (25°C) to approximately -150°C in approximately 12-14 minutes*
- Vapor barrier protects from ambient air
- No direct contact between samples and LN2
Heat sources - Use with water baths, hot plates, incubators and other heat sources to keep samples warm
*Average cooling rate from room temperature How it Works: Ease of Use: - Thermoconductive Tube Rack on ice: heat from the relatively warmer Thermoconductive Tube Rack module is transferred to cooling source (wet or dry ice, cartridge, LN2) until equilibrium is reached
- Thermoconductive Tube Rack in water bath: heat is transferred from water bath toward relatively cooler Thermoconductive Tube Rack until equilibrium is reached

The main advantage of using Ultra Optically Clear Plates is in the optically ultra-clear base of the plate, which gives superior results by delivering low absorbance and high transmission, together with low background signals. Not only this, 4titude ultra-clear base imaging microplate, black frame. The main advantage of using Ultra Optically Clear Plates is in the optically ultra-clear base of the plate, which gives superior results by delivering low absorbance and high transmission, together with low background signals. Not only this, but due to its incredible optical clarity, the ultra-clear base of these plates delivers improved transmission of signals at low wavelengths compared to standard optical films. It allows DNA measurements at 260/280nm wavelengths in a medium or high throughput. Key Features: - Free from DNase, RNase and human genomic DNA
- Ultra-clear base improves transmission for low wavelengths
- Peel-back film on the base for scratch free surface
- Optimum signal-to-noise ratios
- Alphanumeric grid reference to aid well and sample identification
- Suitable for adhesive and heat sealing
- Available barcoded upon request
- Low profile lid available (4ti-0280)

These storage plates are designed for high density sample collection and storage for a wide array of applications within cell biology, molecular biology and drug discovery. They come in three formats: 1.2ml 4titude 1.2ml and 2.2ml square wells, U and V shaped bottom, clear polypropylene. These storage plates are designed for high density sample collection and storage for a wide array of applications within cell biology, molecular biology and drug discovery. They come in three formats: 1.2ml volume U shaped well plates (4ti-0126), 2.2ml volume V shaped (4ti-0132), and 2.2ml volume U shaped (4ti-0136) plates. 4ti-0126 is also recommended as an elution plate on KingFisher™ platforms. All of these plates are ultra-flat for a completely uniform seal, either with adhesive or heat seals, or with our accompanying silicone sealing mat (4ti-0137). These plates are manufactured in cleanroom facilities which are certified free of RNase, DNase, human genomic DNA and endotoxins. We use only the highest medical grade virgin polypropylene with high resistance against chemicals such as DMSO, phenol, and chloroform. Key Features: - Made from polypropylene, a material with very low biomolecular binding characteristics, a high temperature tolerance and resistance to many standard laboratory chemicals, including DMSO
- Autoclavable
- Free from RNase, DNase, human genomic DNA and endotoxins
- Conical V-bottoms (4ti-0132) and U-shaped bottoms (4ti-0126 and 4ti-0136)
- Square wells, to make the best use of space, and to improve mixing
- Alphanumeric grid reference to aid well and sample identification
- SBS footprint
- Clear plate, perfect for storage applications
- Temperature range for use: -80°C to 120°C
- Best for precipitation, centrifugation and small volume recovery due to the conical V bottom, as the liquid gathers at the lowest point of the V for easy pipetting
- U-shaped bottom plates are best for washing, mixing and pelleting and give high surface area
- Stackable
- Suitable for adhesive and heat sealing
- Available with a U-shaped bottom in 1.2ml and 2.2ml
- Also available with a V-shaped bottom in 2.2ml
- Non-sterile as standard, sterilization available upon request
- Available barcoded upon request
- A clear silicone sealing mat (4ti-0137) is also available to fit these plates

The seal prevents evaporation and contamination whilst enabling cells to breathe. It is 4titude gas permeable adhesive seal, peelable; suitable for cell culture Our Cell Culture Adhesive Seal is a gas permeable adhesive seal which seals assay and tissue culture plates, microplates and storage plates. The seal prevents evaporation and contamination whilst enabling cells to breathe. It is made of a non-woven fiber with an acrylate adhesive layer for effective sealing. The seal has a low moisture transfer rate and a porosity enabling gas exchange. Due to its paper-based material it should not be used in wet conditions. The seal is suitable for cell culture and enables long term culture with significantly reduced evaporation. For all adhesive seals, the best sealing results are achieved using the hand held Adhesive Seal Roller (4ti-0502). Key Features: - Peelable
- Seal integrity range: -20°C to 40°C
- Gas permeability rate: 8,900m3/m2/day
- Moisture vapor transmission rate (very low): 4,200g/m2/day
- Air porosity: 10 sec/100 cc/im2
- RNase/DNase free
- Application: bacterial and eukaryotic cell culture
- Sheet format: 135 x 80mm
