Lyophilization, or freeze drying, is a common technique used in the pharmaceutical and food industries to vacuum freeze samples for long-term, ambient storage.

Pipettes are the primary means for transferring liquids, often in milliliter and microliter volumes, into test tubes, microplates, and conical vials for analysis, storage or mixing. Pipettes aspirate a user-selected volume of liquid – samples, reagents, media – from one vessel, then dispense the set volume of liquid into another vessel according to standard operating procedures. Pipettes, or pipettors, are available in a broad range of designs (single-channel or multi-channel), volume ranges, and control systems (mechanical and electronic) for different applications and experience levels.

Liquid nitrogen vessels are designed to support long-term storage of samples at cryogenic temperatures (-196°C to -210°C). The process of cryo-preservation is widely used in clinical diagnostics, immunotherapy development, food and beverage, and semiconductor storage. Samples prepared with cryo-protectants, such as DMSO, can remain viable for up to a decade when stored in liquid nitrogen.

Lab incubators and environmental test chambers are designed to maintain environmental conditions ideal for growing and storing bacterial and mammalian cell cultures.

Gel electrophoresis systems utilize a porous, electrically-charged gel matrix to separate distinct nucleic acid and protein sequences based on molecular weight (or fragment size). The gel box is designed to include a cathode, or negatively-charged electrode, at one end of the medium and an anode, or positive-charged electrode, at the opposite end.

You need to protect sensitive samples, but you don’t want to overpay. Below is a list of application descriptions to help choose the best desiccator storage system for your application and budget.

There are compelling reasons to choose either airflow system depending on clearance requirements, process location, work surface design, and operator safety. Below is a brief comparison (read more on horizontal vs vertical laminar flow hoods).

A cleanroom fan filter unit (FFU) uses HEPA filtration to protect products and personnel inside the cleanroom from unwanted particles and germs. The HEPA filter (or ULPA filter) in the FFU is constructed of delicate tightly woven fibers to catch sub-micron particles. In a typical cleanroom, the fan powered hepa filter mounts on top of the ceiling grid and scrubs air clean as the motor pulls air from outside the cleanroom, pushes it through the HEPA filter and into the cleanroom.The downward top-to-bottom flow of air into the cleanroom provides laminar airflow - a single pass unidirectional flow of air--starting from the ceiling and exiting near the floor--to help flush out other contaminants that may be introduced inside the cleanroom. The clean filtered air being pushed into the cleanroom also creates a positive pressure environment to help keep unwanted contaminants from drifting inside the cleanroom.
