| 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 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
- Available sterile (4ti-0517/ST)

Individual Access 4titude pierceable heat sealing foil, 96 individual seals in sheet format, high solvent resistance, resealable; suitable for PCR/storage/shipping Heat sealing offers a 100% effective method of plate sealing, for complete seal integrity, as well as being quick and cost effective. Individual Access Pierce Heat Seal is compatible with polypropylene and polystyrene plates, featuring 96 individual foil seal spots on a removable backing. This seal demonstrates good solvent resistance and can be used for low temperature and room temperature compound storage in DMSO and organic solvents. These seals result in individually sealed tubes, and they can be pierced with a pipette tip manually, or by a liquid handling robot. Individual Access Pierce Heat Seal can be resealed by applying another Individual Access Pierce Seal straight on top of a previously pierced seal. This seal is available as sheets, for use with manual and semi-automated sealers, such as our Semi-Automated Sheet Heat Sealer. Key Features: - 96 individual foil seal spots on a removable backing
- Pierceable
- 4 pin holes for exact positioning in special adapters of the Semi-Automated Sheet Heat Sealer
- Resealable
- Seal integrity range: -20°C to 120°C
- Good solvent resistance
- Autoclavable (121°C)
- Free from DNase, RNase, human genomic DNA, and endotoxin/pyrogen
- Seals polypropylene and polystyrene plates
- Suitable for long term storage
- Best used in combination with our Individual Access plates
- Sheet format: 127 x 100mm, to fit all standard SBS footprint PCR and qPCR plates, microplates, assay and storage plates
- Non-sterile as standard; sterilization available upon request

It is non sticky when removed from the packaging; this aids handling when wearing gloves. The adhesive is contained within small capsules, allowing light to pass through to ensure the optical clarity of the seal. When the seal is in position, pressure can be applied to burst the capsules, releasing a strong adhesive only where the seal touches the raised well rims of the plate - the rest of the seal area above the wells remains optically clear. Key Features: - Non-pierceable
- Peelable
- Seal integrity range: -80°C to 110°C
- Free from DNase, RNase, and human genomic DNA
- Non-sterile
- Applications: qPCR and other fluorescent applications, plate readers, microscopy and protein crystallization (96 or 384 well)
- Removal: will not leave a sticky residue on the plate surface following removal
- Replacement for: ABI® MicroAmp Optical Adhesive film, Absolute qPCR plate seals and Roche LightCycler® sealing foils
- Sheet format: 140 x 77mm, to fit all standard SBS footprint PCR and qPCR plates, microplates, assay and storage plates with 96 round wells
