Ten discrete fragments ranging from 300 bp to 5000 bp
The Norgen MidRanger 1 kb DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our MidRanger contains ten discrete fragments ranging from 300 bp to 5000 bp. This Ladder is ideal for sizing larger PCR products (>1kb) and most cloning applications.
Contents: 1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
Peelable heat sealing foil which is suitable for low temperature storage, high temperature uses and PCR.
Heat sealing offers a 100% effective method of plate sealing, for complete seal integrity, as well as being quick and cost effective
Our PeelASeal Foil is a laminate seal compatible with polypropylene plates
It can be removed from polypropylene plates by peeling, even with a plate which has been removed directly from -80 °C storage
PeelASeal Foil forms a complete seal to a plate enabling very low temperature uses, including very low temperature storage, and high temperature uses, such as PCR (when used with a pressurized heated lid)
The seal demonstrates moderate solvent resistance and can be utilized for short term compound storage at room temperature
The seal is available as sheets, for use with manual and semi-automated sealers, such as our HeatASeal 500 Sealing Machine
Also available in multiple roll formats compatible with specified automated heat sealers, such as our Wasp or Chameleon XT

Silicone oil thermal conductive shelf, high-precision processing method of upper and lower clamping, shelf temperature uniformity can reach ±0.5°c
Integrated cavity:
Integrated chamber, the shelf and cold trap are located in the same chamber, the steam conduction is faster and the freeze-drying effect is better
Refrigerating and heating control system:
Using thermally conductive silicone oil with a high temperature range and precise PID control algorithm, the control accuracy can reach ±0.5°C. Sample shelf temperature range: -70°C~ +80°C
Freeze-drying endpoint testing system:
The pressure comparison method is used to determine the freeze-drying end point. The freeze-drying end point test can be automatically performed after the analytical drying stage to ensure that the moisture content of the material reaches the standard requirements.
Vacuum precise control and adjustment system:
The sublimation and analytical drying processes are controlled and adjusted with high precision to make the freeze-drying process warmer and the sample sublimation more reliable.
Pulse backfill system:
Three backfilling modes can be selected: slow, medium and fast, which avoids the problem of effective substances being blown away and lost due to the aeration of granular and flocculent materials after freeze-drying.
Manual automatic mode selection:
Manual mode is used to explore process parameters (strong human intervention), automatic mode is used in the mature stage of the process, one-click operation, simple and convenient
Data recording and analysis system:
Through the PC host computer, all operating parameters and background parameters of the equipment can be recorded in real time, and all parameter action changes and action changes of operating components can be recorded.
Freeze-drying process recipe storage function:
The host can store 60 sets of fixed or user-defined freeze-drying process recipes, and the PC can store >10,000 programs (depending on the computer hard drive)
Eutectic point test function:
The eutectic point temperature of the product can be tested offline and online, and the spectrum can be analyzed manually or automatically (optional)
Remote control system:
The operating status of the device can be monitored remotely, and the device can be monitored in real time via WiFi or the cloud.
Mobile phone monitoring system:
You can monitor the operating status of the equipment with your mobile phone, which is simple and convenient (optional)
Cold trap defrost system:
The hot air defrosting method has high safety performance; the defrosting speed is fast, which solves the inconvenience caused by traditional immersion defrosting.
