Plasma- máy hấp tiệt trùng nhiệt độ thấp

Plasma – máy hấp tiệt trùng nhiệt độ thấp

Plasma  là gì?  Plasma là trạng thái của một chất mà chất đó không phải là ở trang thái chất rắn, chất lỏng hay chất khí mà là trạng thái chất đó bị khí ion hóa gọi là plasma, thường gọi là trạng thái plasma. Ở tại trạng thái plasma một phần nguyên tử hay phân tử bị mất đi một vài electon, ở trạng thái plasma chất đó giống như một chất khí, nó không có hình dạng và khối lượng xác định, và có tính dẫn điện. Trạng thái plasma các hạt nhân tích điện dương bơi trong một “biển” các electron tách rời tự do, tương tự như cách các điện tích đó tồn tại trong kim loại dẫn điện, nơi “biển” điện tử này cho phép vật chất ở trạng thái plasma dẫn điện.

Máy đếm khuẩn schuett-biotec

Máy đếm khuẩn schuett-biotecHãng sản xuất: SchuettXuất xứ Đức:Thông số kỹ thuật:

  • Có 3 chế độ chiếu sáng gồm từ dưới lên, bên hông hoặc từ trên xuống (chọn thêm)
  • sử dụng đĩa petri loại Ø 90 mm, Ø 60 mm hoặc Ø 150 mm (chọn thêm)
  • high transparency of colonies reached by LED-light source – practically no heat transferred to the sample
  • light intensity, pressure sensitivity for count and acoustical counting signal adjustable
  • average determination
  • data transfer via USB

Designed for reliable and efficient counting of bacterial colonies and bacteriophage plaques growing on nutrient agar or nutrient disks/filter disks in Petri dishes. For Petri dishes up to Ø 150 mm. Easy adjustable illumination intensity. Three modes of illumination – sideways from below, sideways from above and top-light (optional). State-of-the-art LED-light allows for glarefree illumination without blinding or straylight. No eyestrain. A sofar unknown transparency and differentiation is obtained. Contrast-disk for counting colonies in light and dark fields for the use with clear or dark agar. Adjustable pressure-sensitivity for counting. Designed for ergonomic and relaxed working. Accurate color re-production makes it easier to distinguish between differently coloured cultures on selective culture media and nutrient disks in food analysis. With process water and waste water, the high contrast illumination simplifies the task of distinguishing between colonies that develop within the agar and colonies that grow on the agar surface. The counting impulse is realized by marking the colonies with an ordinary felt-tip marker pen. An acoustical signal confirms each sound its sound level is individually adjustable. The attachment is equipped with a pen holder. With a 4-digit LED-display (0-9999) and a clearly arranged keypad for all controls.

Tủ bảo quản máu KN

KN Series Blood Banking

Tủ bảo quản máu KN is specifically designed to optimize the storage of blood and blood components.
Drawers are designed to hold the maximum number of bags in the smallest footprint while maintaining them in a convenient position for label reading and minimizing heat-up during the opening.

High technology is combined with practical advantages. Perfect for viewing the stock, the triple glass door window has anti-fogging inner glass for top visibility while the external glass prevents ingress of degrading UV light. Switchable inner lights assist with a viewing of the contents.

KN Series Blood Bank Refrigerators are powered by N-Smart™ which has internal memory storing temperature records for up to ten years with one-hour intervals as digitally and graphically. By means of NuveCloser™ software, KN Series Blood Bank Refrigerators can be controlled via the internet. Sample safety is given top priority with an audible, visual, open door and optional NuveWarn™ remote alarm system, plus an optional AlerText™ text message to multiple mobile phones. Sending e-mail up to five e-mail addresses in case of any failure is offered as standard Alarms are independently powered by a permanently recharged battery. The units can be placed in corridors as the door, power switch, and optional chart recorder are all key lock protected.

Technical Specifications:

Capacity: KN 72 with 72 bags; 200 liters.
KN 120 with 120 bags; 306 liters.
KN 294 with 293 bags; 630 liters
Temperature range Set up : 0°C to +10°C.
Advanced technology to store blood and blood components.
