Hirst七天孢子采集器是一種功能得到證實(shí)的裝置,裝有一個(gè)獨(dú)立的真空鼓,在無(wú)人操作的情況下,可連續(xù)七天對(duì)空氣中傳播的微粒進(jìn)行采樣。裝配有鼓準(zhǔn)備附件和完全設(shè)備。可以選擇24小時(shí)無(wú)間斷采樣。
特征:
無(wú)人操作可連續(xù)七天進(jìn)行采樣
內(nèi)置真空泵
精密7-寶石軸承的鐘機(jī)心
可互換的孔
可24小時(shí)連續(xù)采樣
操作可靠簡(jiǎn)便
供電為干線供電、電池或聯(lián)合式干線或電池
Burkard公司產(chǎn)品的主要優(yōu)點(diǎn)是能夠長(zhǎng)時(shí)間的連續(xù)記錄,將孢子壓實(shí)在粘性的透明塑料膠帶上(聚酯薄膜), 膠帶由一個(gè)有固定圓周、7個(gè)寶石軸承的鐘機(jī)心驅(qū)動(dòng)的鼓提供。
該工具安裝在一個(gè)緊致的滑輪上,幫助用戶將鼓和膠帶插入工具的主體,大風(fēng)向標(biāo)使得采樣器對(duì)風(fēng)向的微小變化敏感。
電源或電池
真空泵是由電源供電或電池供電的,可以互換。使用電位計(jì)或計(jì)量螺旋可以對(duì)10升的吞吐量進(jìn)行調(diào)整??梢赃x擇電源或者電池泵,無(wú)需更換泵電機(jī),可以使用任一種電源進(jìn)行操作。
構(gòu)造和配置細(xì)節(jié)
所有的部分都由硬的烤干搪瓷器或作陽(yáng)極化處理進(jìn)行保護(hù),以避免在整除天氣狀況下的腐蝕,在設(shè)計(jì)中采用鋁制作孢子捕捉器使得其重量較輕,方便在現(xiàn)場(chǎng)操作時(shí)手提。
在現(xiàn)場(chǎng)可以快速簡(jiǎn)便的更換鼓,拉出組合在一起的鼓滑輪和鼓室頂部,即可更換鼓,調(diào)節(jié)流量孔板也是簡(jiǎn)便操作的。同時(shí)提供了24小時(shí)的時(shí)鐘、或顯微鏡載(物)片上用于24小時(shí)捕捉的滑輪裝置。
標(biāo)準(zhǔn)配置: 為聚酯薄膜膠帶清理滑輪;1卷雙面膠帶;1卷聚酯薄膜; 1公斤Gelvatol;運(yùn)輸箱;涂層磁鼓可選附件:可替換14毫米×0.5毫米采樣口;流量計(jì);額外的磁鼓;24小時(shí)型滑動(dòng)組件用于顯微載波片采樣;

Product Description
A compact unit with built-in vacuum pump, designed to sample airborne particles such as fungus spores and pollens, continuously for periods of up to seven days without attention.
Particles are impacted on adhesive coated transparent plastic tape supported on a clockwork-driven drum.
Performance of the standard model is similar to the trap described by Hirst in 1952 (Ann. App. Biol. 39, pp 257-265) but interchangeable orifices can be supplied to special order to improve the trapping efficiency for particles in the range 1 to 10 μm diameter.
Construction and Equipment Details
The trap is constructed from materials which are light in weight, making it readily portable for field use. All parts are treated to prevent corrosion against normal weather conditions and the unit finished in Oyster Green hammer enamel. Attention has been given to the changeover of drums, which is quick and simple in operation. Double-sided adhesive tape is used to secure the Melinex tape around the drum. The vacuum pump is available for use most voltages and frequencies. An alternative lid assembly is available to enable monitoring to be carried out over 24 hour periods.
Standard Equipment
The Spore Trap is supplied with one roll of ‘Melinex’ tape and one roll of double sided tape, together with the laboratory stand and Perspex cutting block.
Optional extras
- 42/20 ‘Gelvatol’ available in ? kg packs
- Alternative orifice, size 2 x 14 mm reducing to 5 mm
- Additional drums
- Alternative lid assembly for 24 hour sampling directly onto glass slide
- Flowmeter for measuring throughput at the sampling orifice
- Anodised aluminium carrying case with lid
