Glass test tube, also known as culture tube and sample tube, is a common and widely used glassware, which has a finger-like length, open top and closed bottom. It can be made of soda-lime material, borosilicate glass or quartz glass. And borosilicate glass and quartz glass test tube can withstand high temperatures up to several hundred celsuis.

Output capacity of 120V model is around 2.4Litres/Hour • Can wall or bench mounted • CE marked by independent testing agency • Supplied with an instruction/operating manual • All of the major components are available as spare parts *We recommend that the distillate is tested before use
ESCO Airstream vertical laminar Flow Clean Benches LVG offer proven protection for your samples and processes where operator protection is not required. Vertical laminar flow offers certain tangible advantages over horizontal flow clean benches (which may be conventional in some parts of the world), such as lower energy consumption (40% of conventional systems) levels through the use of exclusive motorized impeller technology and less airflow turbulence (especially when large objects are used in the work zone). In fact, the negative pressure filter mounting system employed on these models is widely recognized to be superior to that of conventional horizontal flow clean benches.
ISO Class 3 air cleanliness within work zone as per ISO 14644.1 (Equivalent to Class 10 as per US Federal Standard 209E, 10 times “cleaner” than the usual Class 100 classification on clean benches offered by the competition).
High-quality polyester pre-filter and main ULPA filter with a typical efficiency of 99.9997% at MPPS and 99.9998% at both 0.3 and 0.12 microns provide the best product protection in the world; typical main ULPA filter lifespan is more than 3 years depending on the usage of the clean bench.
Mini-pleat separator-less ULPA filter technology reduces energy consumption and delivers increased laminar airflow uniformity for better product and cross contamination protection.
Integral filter metal guard on both sides prevents accidental damage to ULPA filter; seamless filter gasket is permanently melded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO) challenge test port included.
OptiMelt provides a fast and accurate means of automatically determining the melting points and melting ranges of chemical substances. With microprocessor controlled temperature ramping, a built-in digital camera, and a selling price that is half that of competing models, OptiMelt offers the best value of any commercially available melting point apparatus.
